The July 2026 edition of the TaiyangNews TOP SOLAR MODULES listing remains unchanged from the previous month, with no commercial module additions, efficiency upgrades, or product delistings affecting the ranking. The 55th edition retains the same 38 products from 31 companies featured in the June edition. On the sidelines, TaiyangNews is reviewing and updating the qualification criteria to better reflect current market conditions
Back-contact (BC) technology continues to maintain its 25% efficiency benchmark for commercial modules, with AIKO and LONGi jointly holding the top spot, sharing rank 1. The next rank is held by TOPCon technology, represented by JA’s module with 24.1% efficiency. HJT remains the segment leader in terms of power, represented by Risen’s 740 W module.
Looking back at the developments during H1 2026, the most significant changes occurred in April 2026. It marked the industry’s first commercially available modules to reach the 25% efficiency benchmark with BC technology. The same month also saw TOPCon technology surpass the 24% efficiency benchmark. JinkoSolar and DMEGC further strengthened the technology’s competitiveness with their commercial products reaching 23.9% and 23.7%, respectively. The top 3 positions are held by BC and TOPCon technologies.
As part of the TOP SOLAR MODULES feature, we list the efficiency leaders for the year 2025, highlighted through the TaiyangNews Badge of Excellence released in December 2025. As part of the TOP SOLAR MODULES Analysis Report 2025, summarizing the findings from an analysis of 24 editions published throughout 2024 and 2025, we announced the names of the companies that are eligible for the Badge of Excellence, which was started in 2023. The rules of the game remain the same – manufacturers who have featured in the Top 10 for at least 6 months within a calendar year are eligible to apply for this badge. The winners of the TaiyangNews Badge of Excellence 2025 are: AIKO, Astronergy, DMEGC Solar, Huasun, JA, JinkoSolar, LONGi, Maxeon, Tongwei Solar, and Trinasolar. Compared to the Badge of Excellence 2024, SPIC slipped off the list, while Trinasolar filled the gap, maintaining the total count at 10.
Efficiency and output power are the 2 key characteristics of a solar module. While there are several ways to improve module power, such as using larger cell sizes or integrating more cells into a module, efficiency is what truly speaks to the solar device's ability to convert sunlight into power per unit area. That’s why this list includes only the highest-efficiency solar modules.
TaiyangNews has been diligently tracking the efficiency progress of solar modules through its annual reports on Advanced Module Technologies, a series that began in 2017. We also provide in-depth coverage of cell and module technology updates in our annual High Efficiency Solar Technologies Conference, the most recent of which took place in December 2025 (access the presentations here).
However, the solar sector is characterized by rapid change, with significant advancements occurring throughout the year. We capture these developments through the various events we organize on different topics. To synthesize this information and provide our readers with frequent updates on global module efficiency progress, TaiyangNews launched this monthly column on commercial TOP SOLAR MODULES at the beginning of 2022.
Furthermore, as mentioned above, TaiyangNews publishes reports analyzing this monthly list, the latest of which was released in June 2026 (see TOP SOLAR MODULES Analysis Report H1 2026).
Before going into the details, here is some background on the methodology and selection criteria: module efficiencies have been improving considerably in recent years. To ensure the list rewards technically advanced products, we set 21.5% as the minimum efficiency criterion for inclusion, and select only commercially available top solar modules from each cell technology stream of each module maker. For example, if a company offers 2 product streams based on PERC with efficiency above 21.5%, only the product with the higher efficiency is considered for this list. However, if a module maker offers, for example, products based on PERC and TOPCon with efficiencies of 21.5% or above, then both products are listed. Efficiency is the only criterion for ranking on the list (where available in the specs, we have used two digits after the decimal point for efficiencies; otherwise, one). However, as we see products with the same efficiency more often, power determines the ranking order in this case. And when both efficiency and power are the same, we list the manufacturers in alphabetical order.
The list does not distinguish between different module formats. All typical module sizes used in rooftop and ground-mounted solar system applications are included and treated equally, as companies increasingly use larger modules in rooftop applications as well.
We only list modules that are based on the manufacturer’s cells produced in-house, which means modules using externally sourced cells are not featured in the TOP SOLAR MODULES list. Having the complete datasheet available on the manufacturer’s website is the first step toward a module being considered commercially available. As such, the efficiency and power data listed here are taken from the datasheet available on the respective company’s website. This also means that any new product announcements without final technical data published are not included in the list, as their module specs often differ considerably from the products that are ultimately available for purchase, and some products presented at trade fairs do not even see commercial light at all. However, the mere existence of an online datasheet generally does not suffice, especially for top efficiencies in the respective technology stream. If module specs listed on company websites appear to have ‘conspicuously’ high efficiencies or new record-efficiency products are announced, we ask for additional proof of commercialization before we include a product in the list.
Starting with the January 2026 edition, we have incorporated a few changes to the table published with this feature.
The columns are rearranged with cell and module parameters in the order of Cell Tech, Cell number, Cell size (in mm), Module technology, Power (in W), Efficiency (%), and Module size (in mm)
The cell sizes are now represented in 2 dimensions (L × W mm), indicating the size of the final individual cell (half-cut, 3-cut, etc.) placed inside the module
The sizes for most of them are collected from the manufacturers or product datasheets, while a few are based on our estimations, which are marked with an '*'
The module technology column now features the type of front and rear cover – glass-glass or glass-backsheet – and eliminates half-cell and MBB, as these are anyway standard
Additionally, the table now features a column with module dimensions
The 'wafer type' column is also removed, as it is common knowledge that all the latest cell architectures are based on n-type, while PERC represents p-type
The July 2026 edition marks the 55th release of TaiyangNews TOP SOLAR MODULES, which continues to feature a total of 38 high-efficiency commercial modules from 31 companies, the same as the previous edition. This month’s edition features no new commercial module additions, upgrades, or delistings, and as such, the positions of all listed products remain unchanged from the June 2026 edition. Separately, TaiyangNews is currently reviewing and updating the qualification criteria for the TOP SOLAR MODULES listing to reflect the latest developments in commercial module technologies.
AIKO continues to hold the top position in the TOP SOLAR MODULES listing, a position it has maintained since the debut of its ABC series in March 2023. However, it has shared the top rank with LONGi since April 2026, with both suppliers listing their modules at 25% efficiency. AIKO’s Comet 3N72 (AIKO-A-MDE72Mw) module remains the company’s highest-ranked commercial product with 25% efficiency and 675 W rated power, marking a milestone for commercial BC technology. The Comet 3N72 succeeds the earlier Comet 2U module (AIKO-G660-MCH72Mw), rated at 24.8% efficiency and 670 W power.
The currently listed module is based on AIKO’s n-type ABC (All Back Contact) cell architecture and comprises 144 half-cells in a 183 × 98.65 mm format. The module measures 2,382 × 1,134 × 30 mm and uses a monofacial glass-backsheet configuration with 3.2 mm tempered glass on the front side. Since all the contacts are on the rear side, the front features a grid-free aesthetic and a uniform appearance. It uses an anodized aluminum frame and weighs 28.2 kg. As with most modules, the first-year power degradation is rated at 1%, followed by an annual degradation of 0.35% from the second year onward, resulting in 88.85% of power retention at the end of 30 years.
Looking back, before the recently replaced Comet 2U module with 24.8% efficiency and 670 W power, AIKO was represented by a 24.4% efficiency module until November 2025, the highest at that time. The company has held the top position ever since its debut, featuring 23.6% efficiency at that time. AIKO went on to break its own record, achieving 24% in June 2023. In May 2024, it further increased efficiency to 24.2% and power to 655 W, while also increasing the module length from 2,278 mm to 2,382 mm. The company repeated this feat in June 2025 by commercializing AIKO-G660-MCH72Mw, improving the efficiency to 24.4% and power to 660 W.
LONGi is represented by its EcoLife series LR7-54HJD-510M module, which shares the top position with AIKO at 25% efficiency. LONGi achieved this important milestone in April 2026, helping it move to the top of our listing. The product is a 510 W module comprising 108 half-cut bifacial back-contact cells in the 182.2 × 96 mm cell format. It measures 1,800 × 1,134 mm and employs 2 mm glass on the front side and 1.6 mm glass on the rear, making it well-suited for residential applications. The module is based on LONGi’s hybrid interdigitated back contact (HIBC) technology, which combines a TOPCon-based passivated contact architecture for one polarity and HJT for the other. The technology also underpins LONGi’s highest certified crystalline silicon cell efficiency of 28.13%, which remains the current world record for a single-junction solar cell. LONGi presented more details about this technology in its presentation at the TaiyangNews High-Efficiency Solar Technologies 2025.
The module uses an anodized aluminum frame and weighs 23.5 kg. The power degradation specified for the product is less than 1% in the first year, with an annual degradation of 0.35% thereafter, resulting in 88.85% of the initial power remaining at the end of 30 years. This represents a major improvement over LONGi’s previously listed EcoLife module, which had an efficiency of 24.7%, entered the ranking in December 2025, and had already placed the company in 2nd.
Until November 2025, LONGi’s best product was Hi-MO 9 with an efficiency of 24.2%, and it has held the 2nd position since March 2025. This 24.2% efficiency level was first featured in our list in June 2025. In March 2025, LONGi moved into 2nd place alongside Maxeon, commercializing its Hi-MO 9 module with 24.1% efficiency, holding this position on its own. Before that, LONGi had held 3rd place since May 2023, when its Hi-MO 6 module's efficiency improved from 22.8% to 23.2%.
The DeepBlue 5.0 JAM66D50-650/GB represents JA in TOP SOLAR MODULES, with 24.1% efficiency, making it the highest-ranked TOPCon module in the listing. Commercialized in April 2026, it marked the first time a TOPCon module surpassed the 24% efficiency benchmark in the listing. The module delivers 650 W at a conversion efficiency of 24.1%, and is currently ranked 3rd. The module is constructed in a bifacial double-glass configuration with a bifaciality of 85±5%. It comprises 198 cells based on the 182 × 70 mm rectangular wafer format and measures 2,382 × 1,134 × 30 mm.
The company’s previously listed module, JAM66D45 640/LB, is based on the DeepBlue 4.0 Pro series, rated at 23.7% efficiency and 640 W power, and was placed 4th. This improvement, from an efficiency of 23.5% (ranked 7th), was reflected in February 2026. Before this, the company was represented by JAM66D45 630/LB until September 2025, with 23.3% efficiency, which improved to 23.5% in October 2025 while the power output increased from 630 W to 635 W.
Previously, the list featured the JAM72D40 model, which entered in July 2024 with 22.8% efficiency and ranking 6th. It was raised to 23.0% in November 2024, moving it to rank 5, and further improved to 23.2% in June 2025, where it remained until it was replaced in September 2025. Before JAM72D40, JA was represented by JAM72D42 630/LB, which had remained unchanged from August 2023 through July 2024.
JinkoSolar is currently represented in the listing by the upgraded version of its Tiger Neo series TOPCon module, commercialized in April 2026. The module achieves an efficiency of 23.9% and a power output of 645 W. This enabled the company to advance from 7th to 4th place, a ranking that remains unchanged in this edition. This bifacial double-glass module is built with 132 n-type TOPCon half-cells. This upgrade represents an improvement over its previously listed 23.69%-efficiency Tiger Neo module. With this update, JinkoSolar retained its position as the second-highest-ranked TOPCon supplier in the current TOP SOLAR MODULES list.
The previous improvement to 23.69% efficiency was introduced in December 2025, placing JinkoSolar 4th at the time. Its stay at this position, however, was short-lived as Risen’s product update pushed it to 5th in January 2026. The company’s JKM640N-66HL4M-BDV, also part of the Tiger Neo series, has a similar architecture to the currently listed module. It incorporates the company’s HOT 3.0 cell design for enhanced light trapping, current collection, and reliability. The module uses 2 mm glass on both sides, achieves a bifaciality of 80±5%, and is backed by a 30-year linear power warranty with only 0.4% annual degradation after the first year.
The company first commercialized its Tiger Neo (JKM625–635N–66HL4M-BDV) TOPCon module in July 2025, with 23.32% efficiency and a 630 W power rating. Until then, the company was represented by a 22.65% product, ranked well below the Top 10. With this major upgrade, JinkoSolar’s ranking jumped sharply from 14th to 5th in July 2025, making it the highest-ranked TOPCon module in the listing at that time.
Within just 3 months, the company further enhanced the module’s performance, increasing efficiency to 23.51% and power to 635 W. As a result, JinkoSolar climbed another step up to 4th place in October 2025 – a significant milestone, as it was the first time a TOPCon module surpassed the top heterojunction (HJT) efficiency benchmark within the TaiyangNews TOP SOLAR MODULES rankings. However, in November 2025, Trinasolar surpassed Jinko, with the former replacing Maxeon at rank 3.
Looking back, the company dropped from 9th to 11th in the July 2024 edition, slipped further to 12th in October, then to 13th in May 2025, and to 14th in June 2025, before its major leap to 5th in July 2025 following the introduction of the Tiger Neo series.
Trinasolar is next in the listing, sharing 4th position with JinkoSolar through its Vertex N series TSM-NEG19RC.20 module. The product features 23.9% efficiency and 645 W of power, representing an improvement over its earlier version, which had 23.7% efficiency and 640 W of power. Before reaching its current position, the product was ranked 3rd, dropped to 4th after Risen’s January 2026 update, and subsequently moved further down the list to 6th as competing products were upgraded, where it shared the rank with two other contestants until May 2026. Built with 132 half-cells based on 210R wafers, the bifacial double-glass module uses 2 mm glass on both sides and offers a bifaciality of 80±5%.
After a significant improvement in efficiency from 23.2% to 23.7% in November 2025, Trinasolar remained in 3rd position until Risen’s move discussed above.
The company was previously represented by the NEG21C.20 module from the same Vertex N series in our listing, from September 2023 until October 2025, with 22.5% efficiency and 700 W of power. It reached 23% in May 2025 and 23.2% in October 2025. Before the Vertex N series, Trina was represented by the Vertex S+ series until August 2023, featuring the same 22.5% efficiency but a lower module power of 450 W.
Back then, although both product groups offered the same efficiency, the Vertex N series delivered higher power of 700 W compared with 450 W for the Vertex S+ series. As a result, the company’s ranking among products with 22.5% efficiency rose from the penultimate position to 2nd place in this group in September 2023.
Risen currently occupies the 6th position with its Hyper-ion Pro HJT module RSM132-8-740BHDG. Although the company held the 3rd position for 3 months with the introduction of its 23.8% efficiency and 740 W power product in January 2026, the subsequent efficiency upgrades by JA and JinkoSolar in April, and Trinasolar’s 23.9% efficiency product pushed Risen down to its current ranking.
The product features 132 half-cut cells of the 210 × 105 mm format. Measuring 2,384 × 1,303 × 30 mm, it is constructed with 2-mm glass on both sides and has a bifaciality of 90±5%. It offers a 1% degradation warranty for the first year and a 90.3% power retention after 30 years. Risen presented its advancements in products and technology at the recent TaiyangNews High-Efficiency Solar Technologies 2025 Conference, held in December, and the presentation can be accessed here.
Risen’s previous module efficiency update came in December 2025, increasing it from 22.5% to 23.5%, a 1% absolute increase, resulting in a big leap in its ranking from 21st to 6th. This improvement resulted from collective advancements at the cell and module levels. Starting at the cells, the structure features microcrystalline silicon passivation layers on both the front and rear sides. As for advancements in metallization, it features a fine finger width, increasing the light-absorption area. The module is based on a zero-busbar (0BB) interconnection layout.
Risen Energy’s Hyper-ion HJT module, first featured in June 2023, ranked 7th at the time, with an efficiency of 22.5% and a high power rating of 700 W.
The 7th position is currently shared by 2 companies, Tongwei and DMEGC, both featuring 23.7% efficiency modules. Tongwei is listed first among the two, owing to its higher module power. Earlier, Trinasolar held this efficiency level alone between November 2025 and January 2026, before being joined by Tongwei and JA in February 2026. The efficiency level remained at rank 4 until March. In April, JA advanced to a higher efficiency level, while DMEGC joined the group by improving its product's efficiency. At the same time, JinkoSolar surpassed the 23.7% efficiency level, pushing the group’s rank down to 6. Further efficiency improvements from Trinasolar pushed it up, with the group’s ranking pushed down to 7th and now represented by Tongwei and DMEGC.
Tongwei’s current module, TWMNF-66HD735, features 23.7% efficiency and 735 W power. The product incorporates a series of improvements at both cell and module levels. At the cell level, it adopts finer finger widths achieved by stencil printing, passivated cut edges using Tongwei’s TPE technology, and poly-fingers on the rear side. Unlike its predecessor, this model is built with the company’s TNC 2.0 cells based on the 210 mm (G12) wafer format and comprises 132 bifacial half-cut cells. The module measures 2,384 × 1,303 × 33 mm and is constructed in a double-glass configuration with a bifaciality of 80±5%. Tongwei presented the technical aspects of TNC 2.0 at the recent TaiyangNews High-Efficiency Solar Technologies Conference 2025, and can be accessed here.
Its previously listed module, TWMND-72HS575-590W, rated at 590 W and 22.8% efficiency, ranked 17th at the time. It was designed with 144 half-cells using its monofacial TNC cell technology on the 182 mm wafer format. The module featured a 3.2 mm front glass and a white backsheet. It was slightly smaller at 2,278 × 1,134 × 35 mm.
Having entered the listing in April 2023, Tongwei improved the top efficiency from 22.5% to 22.8% and power from 580 W to 590 W in February 2024. These improvements enabled it to move from 10th to 6th at the time. However, Grand Sunergy’s entry in October 2024 shifted it down to 7th, followed by further declines to 10th in November 2024 and 11th following Trinasolar’s May 2025 update. It was pushed to 12th in June 2025, to 13th in July 2025, and further to 15th in September. In November, its rank improved to 14th; however, it dropped to a shared 17th in December and remained there until January 2026.
The second member of this group, DMEGC Solar, is represented by its Infinity RT series module, DM640G12RT-B66HSW. The company reached this level by commercializing an upgraded module with 23.7% efficiency and 640 W power in April 2026. It was placed 9th prior to that. The current module comprises 132 half-cells based on 182.3 × 105 mm rectangular wafers, with a 2 mm dual-glass construction. Measuring 2,382 × 1,134 × 30 mm and weighing 32.3 kg, it offers a bifaciality of 80±5%, a rated power retention of 87.4% after 30 years, and an annual degradation of 0.4% from the second year onward.
The Infinity RT series debuted in July 2024 with an efficiency of 22.8%, replacing the Infinity series (based on 182 mm wafers, 144 half-cell format) and moving from rank 10 to 6th. It dropped to 7th in October and then to 9th in November 2024. An efficiency improvement to 23% in March 2025 pushed it up to 5th, where it was grouped with several other TOPCon modules. All these modules dropped a step to 6th in June 2025, to 8th in July, and further to 10th in September 2025. In the October 2025 edition, a product upgrade elevated DMEGC Solar back into the Top 5, placing it in the shared 23.5% (at 620 W) efficiency band with Huasun and JA. It moved down to 6th in December 2025 with Astronergy’s jump to rank 5. With Risen’s update, it moved down to 7th in January 2026, 9th in February 2026, and remained there in March 2026 before the April upgrade lifted it back to 6th.
The next efficiency level is 23.5%, which is shared by 3 companies, GCL, Huasun, and Astronergy, appearing in the same order in the listing based on the ranking methodology. Until April 2026, this group consisted only of GCL and Huasun, ranked 10th. Astronergy joined the group in May, following a correction in its efficiency from 23.51% to 23.5%, which also improved the group’s rank from 10th to 9th.
Leading the group is GCL System Integration (GCL SI), a subsidiary of GCL Group, a vertically integrated, globally recognized silicon supplier to the solar industry. The company’s listed product remains the GCL-N12/66GDF, with an efficiency of 23.5% and a power output of 730 W, following a December 2025 update. With a nearly 1-percentage-point increase in efficiency from its predecessor in the same series (22.53%), the company’s ranking rose sharply from 19th to 6th in December 2025. The company, however, did not disclose the technological improvements that led to this significant gain. The N12/66GDF is a bifacial double-glass TOPCon module comprising 132 half-cells based on the 210 mm wafer format. It measures 2,384 x 1,303 x 33 mm, weighs 38.3 kg, and has a bifaciality of 80±5%. The power performance warranty at the end of 30 years is 87.4% with 0.40% annual degradation from the second year onward.
The NT12/66GDF was first introduced in June 2025 with 22.53% efficiency, replacing the GCL LOTUS series module with 22.3% efficiency. This upgrade improved the company’s ranking from 28th to 17th at the time. It moved down to 19th in the September 2025 edition and dropped another rank to 20th in October. It moved back up to 19th place in November. After moving to rank 6 in December, it fell a rank to 7th in January 2026 with Risen’s update.
GCL SI first debuted in our listing in July 2023 with 2 modules from its GCL GEMINI series – one based on TOPCon and the other on PERC technology. In April 2024, the GEMINI TOPCon module was replaced with a GCL LOTUS series module, although the core specifications remained unchanged. In October 2024, this product dropped from 28th to 29th, tying with Qcells for the rank. GCL SI regained the 28th position in January 2025, as the number of companies at this position fell from 3 to 2 after REC moved up. GCL SI’s PERC product was delisted in December 2025 as it is no longer available on its website.
Representing Huasun at a shared 9th in the listing is its Himalaya series HS-210-B132DS730W module. This module has a conversion efficiency of 23.5% and a power output of 730 W. It is assembled with 132 HJT half-cells using 210 mm wafers. It employs a bifacial dual-glass construction with 2 mm glass thickness, measures 2,384 × 1,303 × 33 mm, and weighs 36.5 kg. With a bifaciality of 90±5%, it is particularly well-suited for utility-scale applications. The module is backed by a 90.3% power retention performance warranty at the end of 30 years, with an annual degradation of less than 0.3% from year 2 onward.
Huasun debuted its Himalaya series module with 22.53% efficiency at 700 W, ranking between 3 and 4. In September 2023, it improved its efficiency and power rating to 23.02% and 715 W, becoming the first to surpass the 700 W threshold on our list, moving it to 3rd position. The product later improved to 23.18% and 720 W in August 2024; however, it ranked 4th due to Maxeon’s improvement at the time. In June 2025, Huasun commercialized an upgraded version of this module with 23.5% efficiency and 730 W of power, maintaining its claim to the highest power rating among all modules listed in the TOP SOLAR MODULES ranking until Risen broke it in the January 2026 edition. In October 2025, the product’s ranking fell to a joint 5th, following JinkoSolar’s rise to 4th place. Later in December, as Astronergy’s TOPCon module moved up with improved efficiency, Huasun’s rank dropped to 6th. In January 2026, it fell to 7th with Risen’s HJT module moving up in the ranking.
The last member of this group is Astronergy, with its Astro N7 series module. Its joint 9th rank was the result of a correction to its module efficiency, from 23.51% to 23.5%. Although the rest of the module specifications remained unchanged, this efficiency change grouped it with GCL SI and Huasun. At the beginning of this year, Astronergy’s rank dropped from 5th in December 2025 to 6th in January 2026. This trend continued in February with a drop to 8th, and then to 9th in April, while its product efficiency remained at 23.51%. These changes resulted from the product upgrades that took place above its position. Rated at 635 W power, the bifacial double-glass module is built with 132 half-cut TOPCon cells based on 182 mm rectangular wafers. It has dimensions of 2,382 × 1,134 × 30 mm and a bifaciality of 80±5%.
The ASTRO N7 series module was added to the listing in March 2025 with an efficiency of 23%, replacing the ASTRO N5, improving the company’s ranking from 7th to 5th. In the July 2025 edition, Astronergy further improved the module’s efficiency to 23.1% and its power to 625 W. Despite these improvements, the module’s ranking dropped from 6th to 7th in July 2025, overtaken by JinkoSolar’s jump to rank 5 at the time. In September 2025, Astronergy reclaimed 6th, improving its efficiency to 23.3%. However, in the October 2025 edition, it moved 2 steps down to 8th, which it held for another month. In December 2025, it jumped to 5th place with a module rated at an improved efficiency of 23.51% and 635 W of power.
Over the past 2 years, Astronergy has progressively improved its module efficiency. The previous ASTRO N5 variant, introduced in September 2023, had its efficiency upgraded from 22.5% to 22.6%, and later to 22.8% by March 2024. By November 2024, the company commercialized a high-power 640 W version with 22.9% efficiency, achieved by increasing the cell count from 144 to 156, which also resulted in larger module dimensions (2,465 × 1,134 × 30 mm).
Unlike the efficiency groups above, the next level at 23.2% is occupied solely by Jolywood at rank 12. The company’s JW-HD144N-R0-600W module continues to represent this position. This JW Pro series is a bifacial dual-glass module built with 144 half-cells based on the M10 wafer size. It uses 2 mm glass on both sides, weighs 31.8 kg, and measures 2,278 × 1,134 × 30 mm.

The module is assembled using 132 half cells based on 210 mm wafers, measures 2,384 × 1,303 × 33 mm, and weighs 38.5±0.5 kg. The module offers 85% bifaciality and comes with a 30-year linear power performance warranty.
In November 2024, efficiency updates from JA and Astronergy led to a drop in its position to 8th, followed by another shift to 9th in March 2025. With Trinasolar improving its module’s efficiency in May 2025, the module moved down to 10th. Jetion Solar’s entry in June 2025 pushed it further to 11th, and another place to 12th in July 2025, following efficiency gains from JinkoSolar and Astronergy. With more efficiency improvements from other companies in the September 2025 edition, it moved to 14th, then to 13th in October, to 16th in December 2025, and eventually to 17th in February 2026.
The delisting of SPIC’s BC product – featuring 22.8% efficiency – in May 2026 resulted in an improvement of all the ranks below by a place.
SolarSpace, one of the leading cell manufacturers that ventured into module production, features both PERC and TOPCon modules in our listing. The company’s highest-ranked module is its Lumina II, a TOPCon series module with 22.65% efficiency and 585 W of power.

It measures 2,278 × 1,134 × 30 mm, weighs 31.2 kg, and offers a bifaciality of 80±10%.
Lumina II, which entered the rankings in July 2023, was upgraded in December 2023 to a high-efficiency variant, increasing its efficiency from 22.02% to 22.45%. In November 2024, the company further enhanced the top efficiency of its commercial TOPCon offering to 22.65%, resulting in a significant jump in its ranking from 20th to 12th. However, subsequent updates from other companies pushed it down to 13th in May 2025, 14th in June, 15th in July 2025, and to 17th in the September and October 2025 editions, and then up to 16th in November. In December 2025, its ranking dropped to 19th, then moved to the current 18th position. Additionally, SolarSpace’s Lumina I, a PERC module with 21.57% efficiency, is one of 5 products tied for the 31st rank on the list. In the January 2026 edition, the company’s SS9-66HD bifacial PERC module advanced 3 steps, from 37th to 34th, due to the delisting of 3 PERC products.
The next efficiency level, 22.6%, is currently shared by 2 companies – Canadian Solar and REC – which are ranked 19th. Earlier, this efficiency level was ranked 20th in April 2026. According to the power order, Canadian Solar warrants the first mention.
Canadian Solar’s highest-ranked product in our listing is its TopHiKu6 series CS6W-585T, a TOPCon module with a conversion efficiency of 22.6% and a power output of 585 W. It is a monofacial module built with 144 half-cells based on the 182 mm wafer format. It features a 3.2 mm glass on the front and a backsheet on the rear. The module weighs 27.6 kg, measures 2,278 × 1,134 × 30 mm, and is backed by a 30-year linear power warranty.

In October 2025, Canadian Solar improved the module's efficiency from 22.5% to 22.6%, with a corresponding increase in power from 580 W to 585 W. As a result of this improvement, the company’s ranking also improved from 21st to 18th, tying with REC Solar. While both companies moved up to 17th in the November 2025 edition, they eventually fell to 20th in April 2026 and then rose to the current 19th after the delisting of SPIC’s BC module.
REC Group, based in Singapore, shares the 19th position with Canadian Solar. Its bifacial Alpha Pure-RX module, manufactured in Singapore, is an HJT module offering 22.6% efficiency and a power output of 470 W. The module comprises 88 half-cut HJT cells and is assembled with 3.2 mm front glass and a backsheet. It measures 1,728 × 1,205 × 30 mm, weighs 22.7 kg, and is backed by a performance warranty of more than 92% power retention at the end of 25 years.
In July 2024, REC Group made a significant update to its product lineup by commercializing the new Alpha Pure-RX module. This module replaced its predecessor, the Alpha Pure-R series, in our listing. Designed with a foil-wire interconnection technology, Alpha Pure-RX is significantly improved over its predecessor, which achieved up to 22.3% efficiency and a module power of 430 W. As a result of this advancement, REC’s ranking jumped from 27th to 12th, then fell a couple of places to 14th in November. It slid to 15th in May 2025, to 16th in June, to 18th in September, up a place to 17th in November, and again down to 20th in the December 2025 listing.
The 22.5% efficiency level is currently represented by only 2 companies – EGING PV and Runergy – both occupying the 21st position. Once one of the most crowded efficiency levels, this group has gradually shrunk as manufacturers commercialized higher-efficiency products and moved to higher ranges. Initially, the number of companies sharing this value declined from 7 to 6 in July 2024, with the collective ranking slipping from 15th to 16th in November 2024. In May 2025, Trinasolar’s advancement to the 23% efficiency band further reduced the count to 5, resulting in another drop in the group ranking to 17th. In June, the group’s position dropped further to 19th. In September 2025, DAS Solar’s improvement reduced the number of companies to 4, with the group ranked 21st. In October 2025, following Canadian Solar’s efficiency improvement to 22.6%, the number of companies in this band further decreased to 3, with the collective group ranked 22nd. In November 2025, following Maxeon’s product delisting, the group’s rank rose to 21st. With Risen Energy’s efficiency update in December 2025, the group's members were reduced to only 2 – EGING PV and Runergy – and their rank dropped again to 22nd. It improved with a delisting in May 2026 to 21st, which remains unchanged in this edition.
EGING PV is represented by its STAR Pro series EG-580NT72-HL/BF-DG module, which offers a conversion efficiency of 22.5% and a power output of 580 W. The TOPCon product is built with 144 half-cells based on the 182 mm wafer format. The module features a 2 mm dual-glass configuration. It measures 2,278 × 1,134 × 30 mm and weighs 31.7 kg.

Runergy, a major Chinese cell manufacturer that expanded into module production, had both its TOPCon and PERC products featured in the listing for the first time in July 2023. The current TOPCon module, initially listed with 22.4% efficiency until November 2023, was upgraded to 22.5% in December, resulting in a significant jump from 21st to 10th place. The ranking gradually declined thereafter, dropping to 12th in April 2024, 14th in July, and to 17th in November 2024. It then moved down to 19th in June 2025, to 21st in September, to 22nd in October, and improved to 21st in November 2025. Due to the efficiency updates above, it dropped to 22nd in December 2025, and moved to 21st in the May edition with the delisting of SPIC’s product.
URECO, a company formed through the merger of 3 leading Taiwanese cell manufacturers – Neo Solar Power, Gintech, and Solartech – offers commercial modules based on all 3 mainstream cell technologies – PERC, TOPCon, and HJT. While the company had all 3 products listed at one point, its PERC and HJT products were delisted in January 2026, as the product datasheets and commercialization information were no longer available on the company’s website.
The company, currently ranked 23rd, is represented by its GLORY series FBF580B8D TOPCon module rated at 22.45% efficiency. While it shared this efficiency level with Qn-SOLAR in the past, the latter’s delisting in October 2025 made it the sole representative of the 22.45% efficiency level.
The 22.4% efficiency level is currently shared by Yingli Solar and Suntech, both ranked 24th. Their collective ranking improved from 26 to 25 in January 2026, and eventually to 24th. Since Yingli’s product has a higher power rating, it is mentioned first in the group. Its PANDA 3.0 PRO 1 series YL625CF78 e/2 model delivers 625 W and features a bifacial dual-glass design comprising 156 half-cells of the 182 mm wafer format. The module measures 2,465 × 1,134 × 30 mm and weighs 34.5 kg.
An early adopter of n-type wafer-based cell architectures, Yingli Solar entered the list in November 2023 with its PANDA 3.0 PRO TOPCon module rated at 22.36% efficiency and 625 W. In the August 2025 edition, its efficiency value was rounded up to 22.4% with no change in power rating, reclaiming its January rank of 27th. After Akcome’s delisting in January 2025, Yingli moved from 28th to 27th, but subsequent efficiency advancements by other manufacturers pushed it down to 29th in June. It briefly climbed back to 27th, slipped to 28th in September, and regained the 27th rank in the October 2025 edition. In January 2026, it ranked 25th following the adjustments to the listing above. In addition, Yingli’s YLM 3.0 Plus 1 PERC module, first listed in February 2022, also adopted a new efficiency representation strategy – changing from 21.57% to 21.6% in August 2025.
Sharing the 24th position with Yingli is Suntech, represented by its Ultra V Pro series TOPCon module. The product is rated at 22.4% efficiency and 605 W of power. Introduced in April 2024, this module replaced the previous 625 W Ultra V Pro Plus module and has remained unchanged since. While the predecessor comprised 156 half-cells, the current module uses a 132-half-cell configuration. Its efficiency, however, has remained unchanged at 22.4%, as have its other characteristics. The module moved from 24th to 25th in October 2024, then down to 27th in June 2025, to 28th in September 2025, before improving by one step each over the next 2 months, and subsequently to rank 25 in January 2026. Another Suntech product, a PERC module first listed in July 2023 with 21.7% efficiency and ranked 32nd, was delisted in February 2026 as its commercialization information was no longer available on the company’s website.
Kalyon PV is the sole occupant of the 22.38% efficiency level, holding the 26th position in the listing. The TOPCon module records an efficiency of 22.38% and an output power of 580 W. It is made with 144 half-cells of the 182 mm wafer format. This bifacial product weighs 32 kg and measures 2,285 × 1,134 × 30 mm.
Kalyon PV, a Türkiye-headquartered vertically integrated PV manufacturer from ingot to module, debuted in March 2024 with its TOPCon module at rank 24, then dropped to 25th in July and to 26th in October. It moved down to 28th in the June 2025 edition, to 29th in August, to 30th in September 2025, and back to 29th in the October 2025 edition before going back up to 27th in April 2026.
Qcells ranks 27th with its Q.TRON series TOPCon module. With 22.3% efficiency and 435 W power output, the module features a 108-cell configuration, most likely based on the M10 wafer format, half-cell, and MBB module technology. The module has a 3.2 mm front glass and a rear composite film construction. It measures 1,722 × 1,134 × 30 mm and weighs 21.2 kg.
The company re-entered our listing in February 2024 with its TOPCon Q.TRON SMART product, which was replaced by a higher-power Q.TRON variant the very next month. While its efficiency remains unchanged at 22.3%, this module delivers 35 W more than its predecessor. Interestingly, the higher power was achieved despite the cell count decreasing from 120 to 108, indicating the adoption of a larger wafer format. Qcells ranked 28th alongside GCL SI until May 2025. However, with the latter’s transition to a higher band in June 2025, Qcells’ module moved to an independent 30th position, followed by another move to 31st in September 2025. In the October 2025 edition, it regained its June position at 30th. It moved up a rank to 29th in November 2025, up to 28th in the April edition, and currently occupies 27th.
CECEP Solar Technology features its High Efficiency series TOPCon module, which slots in at 28th, with 22.1% efficiency and 570 W power. The listed product is assembled with 144 bifacial half-cells based on M10 n-type wafers. The module dimensions are 2,279 × 1,134 × 30 mm, uses a 3.2 mm front glass, and weighs 32.6 kg. It is also backed by a linear power warranty, similar to that of mainstream TOPCon products. Although the module’s specifications have remained unchanged, its position shifted in the listing in response to the shift in rankings among higher-efficiency modules. After moving from 30th to 31st in June 2025 and then to 32nd in September 2025, the module returned to 31st in October 2025. It further improved to 30th in November 2025, to 29th in December 2025, and currently to 28th in May, which remains unchanged in this edition.
Below 22% Efficiency Group
The sub-22% efficiency category includes 10 products: 9 PERC modules and 1 HJT module. The delisting of Meyer Burger’s HJT product in March 2026 reduced the HJT count in this category to 1. The PERC segment also contracted significantly over the past 2 years, although no modules have been delisted since February 2026. The reduction began in July 2024, with Kalyon PV’s PERC module, followed by Tongwei Solar’s product in September. In October 2024, a module each from Astronergy and Talesun was delisted, while JinkoSolar’s module was delisted in December. In total, 5 PERC modules were delisted over H2 2024. Additional PERC delistings from Akcome and Risen Energy followed in January 2025. In July 2025, EGING PV’s PERC module was removed from our listing, as its datasheet was no longer available on the company’s website. With the delisting of JA’s PERC product in October 2025, DAS Solar’s PERC module in November 2025, and GCL SI and Canadian Solar’s PERC modules in December 2025, the count of PERC products dropped to 13. A major reduction occurred in January 2026, when products from LONGi, Trinasolar, and URECO were removed, bringing the total count to 10 within a month. With Suntech’s PERC product phase-out in February 2026, the current product count has been reduced to 9.
Jinergy remains the only company with its HJT module, JNHM144-475, represented by a non-PERC product in this efficiency category. Ranked 29th, the product has a conversion efficiency of 21.85% and a power of 475 W. The dual-glass bifacial module is built with 144 half-cells based on 166 mm wafers. The module measures 2,094 × 1,038 × 30 mm and offers a bifaciality of over 85%.
The current product was updated in September 2023, increasing its efficiency to 21.85%, 0.17 percentage points higher than its predecessor. Compared with the earlier product, the featured JNHM144-475 model is slightly larger, with 144 cells, and thus boasts a higher power rating of 475 W.
Previously, the 22% efficiency level featured a second HJT product, from Meyer Burger, which was delisted in March 2026.
Several commercial modules available today achieve efficiencies slightly above 21.5%, demonstrating that reaching this level does not require high-efficiency cell architectures. However, in order to design products beyond 21.7%, cell technology is key.
Over the past years, we have observed a steady increase in the number of companies achieving module efficiencies of up to 21.7% with PERC. The representation eventually narrowed to a single product – Suntech’s PERC module with 21.7% efficiency and 560 W power – which was also delisted in the February edition.
At its peak, this efficiency level included LONGi and Risen until November 2022. Canadian Solar joined the list of 21.7% efficiency PERC modules in January 2023, Tongwei in February, DAS Solar in April, and Suntech in July 2023. However, Tongwei’s PERC module with shingled technology was delisted in September 2024, reducing the number of companies sharing the rank at the time from 6 to 5. In the January 2025 edition, Risen Energy discontinued its PERC module, prompting its delisting, and further reducing the number of companies to 4. With the delisting of PERC products from DAS Solar in November and from Canadian Solar in December 2025, the 21.7% efficiency group's representation further dropped to 2 companies: LONGi and Suntech.
With the delisting of Meyer Burger’s HJT module, all the ranks below moved up a notch in the March edition.
The next efficiency level is 21.6%, which is currently represented by Yingli alone. Earlier, it was represented by Trinasolar and Yingli until December 2025. With the delisting of Meyer Burger’s HJT, its rank moved up from 32nd to 31st in March 2026, and it is currently ranked 30th with the delisting of the SPIC module mentioned above. It was ranked at 38th in the October 2025 edition, when the efficiency band was represented by GCL SI, Trinasolar, and Yingli Solar’s PERC products, following the delisting of JA’s PERC module. In November, this trio ranked a joint 36th. All 3 modules shared a power rating of 670 W and featured 132 G12-size half-cells. With the details of GCL SI’s PERC product no longer available on its website, the product was delisted. The group, comprising Trinasolar and Yingli, was placed 35th in December 2025, moved to 33rd in January 2026 following the delisting of PERC products from LONGi and Trinasolar, and eventually to 32nd with the phase-out of Suntech’s PERC module in February 2026.
The 21.57% level is currently represented by 5 companies: Jinergy, Qn-SOLAR, Seraphim, SolarSpace, and ZNSHINE- all sharing the 31st position, up from 32nd in April 2026. The group’s rank moved down from 41st in July 2025 to 42nd in August, then to 43rd in September 2025, again to 41st in October 2025, and to 39th position in November 2025. With the 2 PERC products delisted as noted above, the group’s ranking improved to 37th in December 2025 and to 34th in January 2026. All listed products from these companies are built with 132 half-cells of the 210 mm wafer format interconnected with MBB. In addition to sharing the same module efficiency, the products feature identical power of 670 W due to a common wafer format and cell configuration.
The minimum qualification threshold for inclusion in TOP SOLAR MODULES is 21.5%, a category that is currently represented by 3 products at rank 36, one up from April 2026 and 6 steps up from 43rd in the previous edition – Qcells, CECEP, and Runergy.
In the May 2025 edition, within this group, Qcells receives the first mention after introducing an update with a new high-power PERC module rated at 600 W, replacing its earlier 590 W version. While its efficiency remains unchanged at 21.5%, only the power increased compared to its peers’ 555 W.
There have been several new commercial module announcements with higher efficiencies in the recent exhibitions and events, which have not made it to the TOP SOLAR MODULES July 2026 edition. Separately, with all the recent developments in view, TaiyangNews is reviewing and updating the qualification criteria for the commercially available modules to feature in the listing.
This month’s edition essentially remains the same as the last one in terms of the listed modules and companies.
It features 38 high-efficiency commercial modules from 31 companies. BC retains its leading position at the 25% efficiency level, with AIKO and LONGi. TOPCon follows next, with JA leading with its 24.1% efficiency module. HJT products continue to occupy several positions in the ranking, with the highest at 6th.
