TOP SOLAR MODULES Listing – July 2025

Following dramatic changes in the TaiyangNews TOP SOLAR MODULES listing last month, this July edition features subtle changes. While no new companies have joined the list this month, there are 2 notable efficiency upgrades from 2 companies. JinkoSolar and Astronergy have provided proof of commercialization for their modules, which have higher efficiency than the ones listed previously. As a result, the top efficiency of JinkoSolar’s product reached the top of TOPCon modules in our list, albeit marginally (at second order of decimal / at second decimal place) higher than the previous topper. JinkoSolar’s new module, with an efficiency of 23.32%, replaces its previous 22.65% product, a sharp 0.67% absolute jump. The company did have a few high-efficiency commercially available TOPCon modules; however, we received the necessary proof of commercialization only this month. In fact, many companies are now promoting TOPCon modules with efficiencies above 22.5%. However, we include such products in our ranking only after verifying that they are indeed commercially available.

This edition features another upgrade: Astronergy’s commercial TOPCon efficiency reached new heights, up from 23% to 23.1%. Astronergy has been updating us with its shipment data for its top products periodically, giving the impression of organic efficiency improvements.

The current edition also features a deletion. The specs for EGING PV’s PERC product are absent from the company’s website, leading to its delisting. The company is likely divesting from PERC technology, following in the footsteps of other leading manufacturers. As a result, the number of products listed in the July edition of TOP SOLAR MODULES has been reduced to 50 from 51, while the count of companies remains at 33.

As always, efficiency remains the primary metric of comparison, and the leaderboard continues to reflect this, with the top 3 positions still held by BC (Back Contact) technology represented by AIKO, LONGi, and Maxeon, followed by Huasun’s HJT module in 4^th place.

As part of this TOP SOLAR MODULES feature, we would also like to acknowledge last year’s efficiency leaders, highlighted through the updated TaiyangNews Badge of Excellence released in January 2025. As part of the TOP SOLAR MODULES Analysis Report 2024, summarizing the findings from an analysis of 24 editions published throughout 2023 and 2024, we also announced the names of the companies that are eligible for the Badge of Excellence Started in 2023, the Badge of Excellence extended to 2024. 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 Excellence Badge 2024 are: AIKO, Astronergy, DMEGC Solar, Huasun, JA Solar, JinkoSolar, LONGi, Maxeon, SPIC, and Tongwei Solar.

Background

Efficiency and output power are the 2 key characteristics of a solar module. While there are several means to improve module power, such as employing larger cell sizes or integrating more cells into a module, it’s the efficiency that truly speaks to the ability of the solar device to convert sunlight into power per 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 2024 (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 is released in June 2025 (see TOP SOLAR MODULES Analysis Report H1 2025).

Methodology

Before going into the details, here is some background on the methodology and selection criteria: module efficiencies have been improving considerably in recent years. In order to make the list rewarding for technically advanced products, we set 21.5% as the minimum efficiency criterion to feature in the list. We have listed only commercially available top solar modules from each cell technology stream of a module maker. For example, if a company is offering 2 different product streams based on PERC that have more than 21.5% efficiency, then only the product with the higher efficiency is considered for this list. But if a module maker is offering, 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 in the list (whenever available in the specs, we have used 2 digits after the decimal point for efficiencies; otherwise, one). However, as we see products with the same efficiency more often, power determines the order in this case. And when both the 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 also for rooftop applications.

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 data sheet listed on its manufacturer’s website is the first step for a module to be considered a commercially available product. 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 finally available for purchase, and some products presented at trade fairs do not even see commercial light at all. However, just the existence of an online datasheet generally does not suffice, especially for top efficiencies in the respective technology stream. If module specs listed on the websites seem 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.

Results & Changes

The latest edition of our TOP SOLAR MODULES list, compiled in early July 2025, features 50 high-efficiency modules from 33 manufacturers. While the overall count has declined from the previous month by one, due to the delisting of a single product, the update brings with it 2 improvements in the TOPCon stream.

One of the most notable changes is the commercialization of a high-efficiency TOPCon module from JinkoSolar. The company’s newly listed module, with a rated efficiency of 23.32% and a power output of 630 W, replaces its earlier 22.65% efficiency product, which had been part of the list since September 2022. This marks a big leap of 0.67 percentage points in module efficiency.

Being a pioneer of TOPCon technology, JinkoSolar has been improving the efficiency of its commercial TOPCon products. However, the company provided proof of commercialization only in this edition. As a result, in addition to moving up a rank, JinkoSolar now also tops the TOPCon segment.

Another TOPCon efficiency upgrade comes from Astronergy, which improved its ASTRO N7 module’s efficiency from 23.0% to 23.1%, while simultaneously increasing the rated power from 600 W to 625 W. This is the same module, which has seen its first refinement in July, after debuting in March 2025 at 23.0% efficiency.

This edition also features a deletion; EGING PV’s PERC product, featuring an efficiency of 21.56%, has been delisted as its datasheet is no longer available on the company’s official website – a key criterion for the products to be part of the TOP SOLAR MODULES list. However, this is not surprising, as several leading companies are moving out from PERC production, a trend that started in H2 2024.

AIKO has retained its top seat ever since announcing its entry into the list in March 2023, with its ABC series module boasting an efficiency of 23.6%. AIKO further cemented its dominance in June 2023 by breaking its own record and achieving a landmark 24% efficiency for a commercial module with another ABC series module. Again, after about a year, in May 2024, AIKO continued its legacy with its latest Comet 2U series, featuring 24.2% efficiency. In June 2025, AIKO has once again raised the bar by commercializing its latest product – AIKO-G660-MCH72M – which maintains the same form factor as its predecessor, featuring identical dimensions, a monofacial design, and a grid-free front that gives it a uniform and aesthetically pleasing appearance. While the structure remains unchanged, both power and efficiency have improved – the power output has increased from 655 W to 660 W, and the efficiency has increased from 24.2% to 24.4%. These gains are most likely the result of cell-level advancements.

The previously listed Comet 2U series module, rated at 655 W, was already a step up from AIKO’s previous ABC modules. Built with 144 half-cells of the M10 format, it introduced a larger module footprint, with the length extended from 2,278 mm to 2,382 mm, while the width remained at 1,134 mm. This increase in size contributed to a 35 W power gain over its 620 W predecessor. It is a monofacial module featuring a grid-free front design for improved aesthetics and uniform appearance.

The company has supported its claims with third-party lab test data, shipment records, and a list of commercial-scale projects already deploying this module series.

LONGi had held the 3^rd place since May 2023, when its Hi-MO 6 module improved from 22.8% to 23.2% efficiency. In March 2025, the company moved up to share the 2^nd position with Maxeon after commercializing its Hi-MO 9 module featuring 24.1% efficiency. In June 2025, LONGi improved it again by commercializing a new high-efficiency module reaching 24.2%. As a result, LONGi is now in sole possession of the 2^nd place, while Maxeon moves down to 3^rd. This product remains unchanged in the current July edition.

The Hi-MO 9 module, based on LONGi’s proprietary HPBC (Hybrid Passivated Back Contact) cell technology, utilizes the company’s TaiRay wafer and BC technology. The product – named LR8-66HYD – that replaces the previously listed LR7-72HYD, has the same external dimensions of 2,382 × 1,134 × 30 mm and a weight of 33.5 kg. However, LR8-66HYD is built with 132 half-cut cells, compared to the 144-cell layout of its predecessor. It achieves a maximum efficiency of 24.2% and a power output of up to 655 W, which is slightly higher than the earlier model’s 24.1% and 650 W. Despite the reduced cell count, the listed module delivers improved performance, likely due to a change in the wafer configuration apart from design and material enhancements. Additionally, it features an improved spec for bifaciality, up from 70±5% to 75±5%.

In addition to development on the commercial front, LONGi has also been working at the lab level, with its 27.3% efficiency still the highest for crystalline silicon solar cells. The company is also in the process of commercializing a very high-efficiency model with 24.4% efficiency and a power rating of 660 W under the same Hi-MO 9 series.

Maxeon Solar moved from 2^nd to 3^rd position in June 2025 following LONGi’s update. Previously, it had moved up to share the 2^nd rank with LONGi by introducing its latest high-efficiency Maxeon 7 module, which replaced its Maxeon 6 series. Despite maintaining the same power output of 445 W, the Maxeon 7 module has seen an impressive increase in efficiency from 23% to 24.1%. Similar to its predecessor, this IBC module features a sleek design with a white backsheet and a black frame structure. An important point to note here is that, unlike the previous product, which was built with 166 mm wafers, this Maxeon 7 series module is built with 112 cells based on a 125 mm wafer size. The Maxeon 7 panel comes with a 40-year performance warranty.

Thus, the Top 3 positions are now occupied by 3 different companies – AIKO, LONGi, and Maxeon – and interestingly, or perhaps unsurprisingly, all 3 are based on back-contact (BC) technology.

Huasun’s HJT module, which was introduced in September 2023, moved up to the 4^th position in May 2024 due to improved efficiency and power ratings. Until August, Huasun’s top product was listed with 22.53% efficiency and 700 W of power. The Himalaya series module from Huasun is based on the G12 wafer size in a 132-half-cell configuration. It became the first product on the list to surpass the 700 W threshold, later improving to 23.18% efficiency and 720 W power output in August 2024.

Commercializing an upgraded version of this module with 23.5% efficiency and 730 W of power, Huasun has once again raised the bar in the latest June edition, maintaining its claim to the highest power rating among all modules listed in the TOP SOLAR MODULES ranking. This bifacial module features 2 mm double glass and boasts a bifaciality of 90±5%, making it particularly well-suited for utility-scale applications. It measures 2,384 × 1,303 × 33 mm, weighs 37.9 kg, and is backed by a 15-year product and 30-year power warranty. Despite the performance upgrade, the module remains ranked 4^th, due to even more aggressive advancements among the top 3. This product from Huasun also leads the HJT pack in efficiency.

When it comes to TOPCon, the technology continues to make notable strides at the macro level, inching closer to HJT’s performance levels. JA Solar led the charge in June 2025, improving its top commercial module to 23.2% efficiency and 600 W power output. In addition to being the top efficiency among TOPCon products, 23.2% was also close to the efficiency of the top HJT product from Huasun till May 2025. This month, JinkoSolar takes the lead in the TOPCon segment by commercializing a significantly improved module with 23.32% efficiency and a power output of 630 W. Till last month, the company was represented with a 22.65% product. With this 0.67-percentage-point efficiency increase over its previously listed product, JinkoSolar now holds the top position among all TOPCon modules and has entered the overall Top 5 as a result – pushing JA Solar to 6^th place.

Taking a quick glance at JinkoSolar’s product ranking over the past year, the company dropped from 9^th to 11^th in the July 2024 edition and slipped further to 12th in October. It moved down to 13^th in May 2025 and then to 14^th in the June 2025 update, before its move up in the current edition.

JinkoSolar’s currently featured product – JKM625-630N-66HL4M-BDV – built with 132 half-cells is rated for up to 630 W of power and a maximum efficiency of 23.32%. Built on n-type monocrystalline cells with TOPCon architecture, the bifacial module incorporates JinkoSolar’s HOT 3.0 technology, designed to enhance light trapping, current collection, and overall performance stability. The dual-glass module, with 2 mm glass on both sides, has a bifaciality of 80±5% and is backed by a 30-year linear power warranty with 0.4% annual degradation after the first year. With this upgrade, JinkoSolar’s ranking has jumped sharply from 14^th place in the June edition to 5^th position in July

JA Solar improved the efficiency of its DeepBlue 4.0 Pro series module JAM72D40 600/MB to 23.2% from 23.0% in June 2025. Its previously best-performing TOPCon module, the JAM72D42 630/LB, which had remained unchanged since August 2023, was replaced in July 2024 by JAM72D40 590/MB. This module from the DeepBlue 4.0 series initially featured an efficiency of 22.8%, up from 22.5% previously, and improved further to 23% in November 2024. Despite consisting of the same 144 half-cells of M10 size and higher efficiency, this module featured a lower power rating of 595 W, which is 35 W less than its predecessor’s 630 W. This is obviously due to a change in the wafer format.

JA Solar has developed 3 different half-cell formats derived from a single wafer size of 182 × 199 mm. One format involves cutting the cells into 2 symmetrical pieces along the longer length into 99.5 mm each. Cutting the same cell asymmetrically – one at 105 mm and another at 94 mm – gives 2 additional base formats. The company has designed several module configurations based on these 3 different wafer formats. Although not explicitly mentioned in the datasheet, the earlier product, measuring 2,465 mm in height, seems to have been built with 99.5 mm half-cell wafers. The presently featured product, with a height of 2,278 mm, is most likely based on the smallest wafer size of 94 mm. This is a bifacial double-glass module with a bifaciality of 80±10%, interconnected with 16 busbars, weighing 31.8 kg. However, its ranking followed a different pattern as it also depends on the progress of products from other companies. In the current edition, JA Solar ranks 6^th.

Another major update this month comes from Astronergy. 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 improved to 22.8% by March 2024. By November 2024, the company launched 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). In March 2025, the ASTRO N7 series entered the listing with an efficiency of 23%, replacing ASTRO N5 and improving the company’s ranking from 7^th to 5^th. The bifacial TOPCon module is composed of 132 half-cut cells based on 182 mm rectangular wafers. Compared to the previous model, the N7 module is slightly shorter in length at 2,382 mm, while its width and thickness remain the same at 1,134 mm and 30 mm, respectively. It has a bifaciality of 80±5%. In the current July edition, Astronergy has further improved the module’s efficiency to 23.1% and its power to 625 W. Despite these improvements, the module’s ranking has dropped from 6^th to 7^th, overtaken by JinkoSolar’s module mentioned above.

With JA Solar’s move up in June and Astronergy’s further improvement this month, the group of companies previously sharing the 23% band has now been pushed down to Rank #8. This band is currently represented by 3 companies – Trinasolar, Tongwei Solar, and DMEGC Solar – down from 4 in June and 5 in May.

Trinasolar’s Vertex N series replaced the previous Vertex S+ in the September 2023 edition. Back then, while both product groups had the same efficiency, the former had a high power of 700 W compared to 450 W for the latter. Thus, the company’s order among the products with 22.5% efficiency went from the penultimate position up to 2^nd from the top in May 2024. The currently listed TSM-NEG21C.20 module is built with 132 half-cells based on 210 mm wafers. This bifacial module uses a 2 mm glass on both sides and offers a bifaciality of 80±5%. Keeping these core specifications unchanged, the module improved its efficiency and power to 23% and 715 W in May 2025. This moved Trina up to 5^th from 16^th position at the time, though it dropped to 6^th in June following JA Solar’s update. It has now slipped further to 8^th in the current edition due to JinkoSolar’s jump to 5^th and Astronergy’s move to 7^th. Nonetheless, the Vertex N module remains one of the highest-power products among TOPCon modules and also among those in the 23% efficiency band.

In December 2023, Tongwei Solar also started offering a 715 W HJT module, which entered the list ranked 4^th. It then moved to 5^th in May 2024 and to 6^th in June 2025. Till November 2023, Tongwei was only represented in the TOPCon segment and PERC (shingled) modules. With the inclusion of this HJT product, Tongwei was among the few companies to have featured simultaneously in all 3 different technology streams in our listing. However, its PERC module was delisted in September 2024, narrowing its representation to 2 streams. Tongwei’s HJT module is built with 132 half-cells of the 210 mm format. It is designed with the company’s THC cells – an n-type HJT cell technology. The highest power rating for this bifacial module is 715 W, with an efficiency of 23%, and it shares the 8^th position with Trinasolar. Tongwei has also provided production details and a testing report for this panel. The company presented the details of its latest products during the TaiyangNews PV System Technology Trends – SNEC & Intersolar Product Review Conference, which can be accessed here.

DMEGC Solar’s Infinity series TOPCon module, which was updated in April 2024 with 22.6% efficiency, was replaced by the Infinity RT series in July 2024. This module is built on the 210 mm rectangular wafer format and a 132-half-cell configuration. Compared to its 182 mm, 144-half-cell configured predecessor, this module has a 30 W higher rated power (610 W) and boasts an efficiency of 22.8%. Having moved up to 6^th from 10^th in July 2024, this module dropped to 7^th in October and then to 9^th in November 2024. An improvement in its efficiency to 23% in March 2025 pushed it up to 5^th, where it was grouped with several other TOPCon modules. Along with the above 2 companies, the rank of DMEGC Solar also dropped one step down to 6^th in the previous edition. The module’s dimensions are 2,382 × 1,134 × 30 mm, and it weighs 32.3 kg. The 2 mm double-glass module features a bifaciality factor of 80±5%. In the current edition, DMEGC Solar’s module has moved down to 8^th place, alongside Trina and Tongwei.

Another major highlight in the June edition was the entry of a new company into the TOP SOLAR MODULES list. Jetion Solar, established in 2004 and operating under the China National Building Materials Group Corporation (CNBM), is a vertically integrated PV manufacturer with production capabilities spanning solar cells and modules. The company operates 5 manufacturing facilities across China and Thailand, with a total cell production capacity of 4.4 GW and a module capacity of 2.5 GW.

Jetion Solar joined the listing at the 10^th position with its HJT module, featuring a rated maximum efficiency of 22.9% and a power output of 710 W. Its JT SLk(B) series module features bifacial, dual-glass HJT technology, and incorporates 132 half-cut monocrystalline cells based on the 210 mm wafer format. It measures 2,384 × 1,303 × 33 mm and weighs 36.4 kg. The module offers a bifaciality factor of approximately 90±5% and utilizes 2.0 mm high-transmission, AR-coated tempered glass on both the front and rear sides. It is backed by a 15-year product warranty and a 30-year linear performance guarantee. Its Top 10 debut in June, however, was short-lived, being pushed to 11^th in the current edition due to efficiency improvements by other manufacturers.

Grand Sunergy, a China-based manufacturer specializing in HJT cell manufacturing, entered the renewable energy sector in 2022. Its HJT module first appeared on the list in October 2024 with an efficiency of 22.86%, initially ranked 6^th. Subsequent efficiency updates from JA Solar and Astronergy in November 2024 led to a drop in its position to 8^th, followed by another shift to 9^th in March 2025. With Trinasolar’s latest efficiency improvement in May, the module moved down to 10^th. In June, it was pushed to 11^th with Jetion Solar’s entry, and has now dropped another place to 12^th following efficiency gains from JinkoSolar and Astronergy. Its GSM-MH3/132-BHDG710 module, which delivers a power output of 710 W, utilizes G12 large-size wafers and measures 2,384 × 1,303 × 33 mm, with a weight of 38.5±0.5 kg. It features an 85% bifaciality and is supported by a 30-year linear power warranty.

The next efficiency band on our list is 22.8%, which was represented by 5 products in July 2024. Its representation was reduced to only 3 products in November 2024, following Astronergy and JA Solar, which were previously part of this group, having moved up with higher efficiency modules. The ranking for this group has gradually declined – from 9^th in November 2024, to 10^th in March 2025, 11^th in May, 12^th in June, and now to 13^th in July.

Tongwei Solar updated the efficiency of its TOPCon panel in February 2024. The module, which entered the list in April 2023, improved its efficiency from 22.5% to 22.8%, along with an increase in power from 580 W to 590 W. These improvements enabled its move from 10^th place to 6^th. However, Grand Sunergy’s entry in October 2024 shifted it down to 7^th, with further declines to 10^th in November and 11^th following Trinasolar’s May update. In June 2025, it was pushed down another step to 12^th, and now ranks 13^th. The product is designed with a TNC cell type and an anodized aluminum alloy frame, and features a linear power output warranty of 30 years. This product is built with 144 half-cells of the G12 wafer format.

Ranked 6^th from December 2023 until September 2024, SPIC moved down to 7^th in October and to 9^th in November, alongside its fellow rankers. With subsequent advancements by LONGi, Astronergy, and DMEGC Solar, the rankings of Tongwei and SPIC both slipped to 10^th in March, then to 11^th in May, 12^th in June, and now share the 13^th position in the July 2025 edition. The 2 companies have been equally placed since March 2025.

While SPIC had been promoting a product with 22.3% efficiency till August 2023, it made a remarkable change in September 2023 by improving it by 0.5% absolute. Its Andromeda 3.0 product series features a top efficiency of 22.8%. The Chinese company has also provided shipment and production data, indicating the product’s commercial availability. The module features an elegant full-black design combined with SPIC’s TBC cell technology, which is an IBC concept adopted on a TOPCon base cell architecture. The module, with a bifaciality of 70% and built with 120 half-cells, has a power rating of 410 W. SPIC offers a 30-year power warranty for this product.

SolarSpace, a leading cell manufacturer that has ventured into module production, is represented in our listing with both PERC and TOPCon modules. The Lumina II TOPCon module, 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 20^th to 12^th. However, subsequent updates from other companies pushed it down to 13^th in May 2025, 14^th in June, and to 15^th in the current July 2025 edition. This 580 W module is composed of 144 half-cells that are based on the 182 mm wafer format. Additionally, SolarSpace's Lumina I, a PERC module with an efficiency of 21.57%, is one of 7 products tied for the 41^st rank on the list. In December 2024, the SS9-66HS mono PERC module was replaced with the SS9-66HD bifacial PERC module.

In July 2024, REC Group, the Singapore-based manufacturer, made a significant update to its product lineup by commercializing the new bifacial Alpha Pure-RX module. This module replaced its predecessor, the Alpha Pure-R series, in our listing. This HJT module boasts an efficiency of up to 22.6% and a power output of 470 W. Designed with foil-wire combination interconnection technology, the Alpha Pure-RX is significantly improved compared to its predecessor, which had an efficiency of up to 22.3% and a module power of 430 W. As a result of this advancement, REC’s ranking jumped from 27^th to 12^th and then a couple of places down to 14^th in November. It slid to 15^th in May and to 16^th in June, where it remains in the current edition.

The Alpha Pure-RX module is built with 88 half-cut bifacial HJT cells, compared to 80 cells in the Alpha Pure-R, contributing to its higher power. The physical dimensions of the Pure-RX module are slightly larger, measuring 1,728 × 1,205 × 30 mm and weighing 22.7 kg, compared to the Pure-R’s 1,730 × 1,118 × 30 mm and 21.5 kg. It also features a bifaciality of 80±10%. Constructed with a highly resistant black polymer backsheet and an anodized aluminum frame, the module is manufactured in Singapore and is accompanied by a comprehensive 25-year product and power warranty.

GCL System Integration (GCL SI), a subsidiary of the vertically integrated GCL Group – the globally recognized silicon supplier to the solar industry – provides solar modules, battery storage products, and complete PV solutions. In the July 2023 edition, 2 modules from its GCL GEMINI series were listed – 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, this product dropped from 28^th to 29^th, sharing its rank with Qcells. GCL regained the 28^th position in January 2025, as the number of companies at this position fell from 3 to 2 following REC’s move up in July. In June 2025, the listing was updated with a new commercial product – GCL-NT12/66GDF. This bifacial, half-cell module features n-type TOPCon technology, built on the 210 mm wafer format with 132 cells. It delivers a rated power of 700 W and achieves a module efficiency of 22.53%.

The design incorporates a multi-busbar (MBB) architecture, and the product is confirmed to be commercially available. The PERC product from GCL SI is listed at 38^th.

Jolywood, one of the early adopters of TOPCon technology, currently shares the 17^th rank. The last change for this product was in August 2023 when its former Niwa Light module was replaced with a bifacial product called Niwa Pro, which has the same specifications – 440 W power and 22.53% efficiency.

The next group of products, all rated at 22.5% efficiency, saw the number of companies sharing this spot reduce from 7 to 6 in July 2024, with the collective ranking slipping from 15^th to 16^th in November 2024. In May 2025, Trinasolar’s advancement to the higher 23% efficiency band further reduced the count to 5, leading to another drop in the group ranking to 17^th. In June, the group’s position slipped further to 19^th, and it remains unchanged in the July edition.

Risen gets the first mention among the 19^th rankers, a group that is structured according to power first and, if equal, according to alphabetical order. Risen Energy’s Hyper-ion module, which was included in June 2023, remains unchanged. This HJT module from Risen has an efficiency of 22.5%, corresponding to a high rated power of 700 W.

Runergy’s TOPCon module, initially listed with an efficiency of 22.4% until November 2023, was upgraded to 22.5% in December, resulting in a significant jump from 21^st to 10^th place. The ranking gradually declined thereafter, dropping to 12^th in April 2024, 14^th in July, and to 17^th in November. It then moved down to 19^th in June 2025, with no change in its ranking this month.

Runergy, a major Chinese cell manufacturer that expanded into module production, had both its TOPCon and PERC products featured for the first time in July 2023. The listed TOPCon module, HY-DH144N8, is a bifacial product built with 144 half-cells using the 182 mm wafer format and offers a maximum efficiency of 22.5%.

As a result of module efficiency upgrades, the 22.45% efficiency level has seen a drop in numbers to 2 since November 2024, down from 3 in October and 4 in April of the same year. . In the July 2024 edition, the collective ranking of these companies dropped from 19^th to 20^th, and then to 22^nd in November 2024, with SolarSpace’s TOPCon module moving up that month. In June 2025, the group’s position declined further to 24^th, where it remains currently.

Shanghai-headquartered solar cell and module manufacturer Qn-Solar entered our listing in July 2023. Launched in 2014 and initially a project developer and EPC, the company also operates its own power plants and has been strongly expanding into the manufacturing field recently. According to the company’s website, it had 69 GW of cell and 39 GW of module production capacity in 2023. Its TOPCon module, with an efficiency of up to 22.45%, qualifying it for the shared 15^th position with DMEGC in July 2023. Qn-Solar’s listed bifacial TOPCon product has a rated power of 580 W and consists of 144 half-cells built on the 182 mm wafer format.

URECO is a manufacturer formed from the merger of 3 leading Taiwanese cell manufacturers – Neo Solar Power, Gintech, and Solartech. The company offers products based on all 3 mainstream cell technologies – PERC, TOPCon, and HJT. While its PERC products were already part of our earlier listing, the modules based on the 2 remaining advanced cell technologies were included in our August 2023 edition. Named GLORY, the company’s TOPCon series is represented by its FBF580B8D model featuring an efficiency of 22.45%, which means it is the 2^nd company to share the 24^th rank. URECO’s HJT module, with a rated efficiency of 22.44%, very narrowly misses the spot by 0.01%, slotting in 2 ranks down at 26^th. Called GLORY HELLO, the module is built with 120 half-cells of the 210 mm wafer format and has a power rating of 635 W.

Suntech’s module, which saw a change in April 2024, has remained unchanged since. The Ultra V Pro Plus module with 625 W was replaced with the lower-power 605 W Ultra V Pro. The latter is built with 132 half-cells, while the former consisted of 156 half-cells. While its power output has changed, the module’s efficiency remains at 22.4%, as do its other characteristics, including TOPCon cells and bifacial module technology. Following this update, the module moved from 24^th to 25^th in October 2024, and then to 27^th in June 2025, a position it retains in the current edition. Another Suntech product, first listed in July 2023, boasts an efficiency of 21.7% and ranks 34^th, thus making it one of the highest-rated modules in the PERC category.

Kalyon PV, a Turkey-headquartered vertically integrated PV manufacturer from ingot to module, debuted in March 2024 with its TOPCon module at Rank 24, dropped to 25^th in July, and then to 26^th in October. In the June 2025 edition, the module moved down to 28^th. With 4 factories and an R&D center, the company commenced production in 2019. Its TOPCon module, with 22.38% efficiency and 580 W power output, features M10 half-cut cell technology and a bifacial module design. Another module from Kalyon, listed in the PERC category from March 2024 until July 2024, has since been delisted.

Yingli Solar, one of the early adopters of n-type wafer-based cell architectures, entered the list in November 2023 with its PANDA 3.0 PRO, a TOPCon module product that remains unaltered. The cells used in this module are manufactured in-house. The company has 5 GW of cell production capacity for TOPCon and 20 GW of module capacity for PERC and TOPCon. The listed bifacial module, comprising 156 half-cells, is interconnected with MBB technology and has an efficiency and power output of 22.36% and 625 W, respectively. Following Akcome’s delisting in January 2025, Yingli moved up one rank from 28^th to 27^th. However, due to recent efficiency advancements by other manufacturers in June, the module dropped one rank to 29^th. Additionally, another Yingli product in the PERC category, first listed in February 2022, remains in the current edition with a ranking of 41.

Qcells re-entered our list in February 2024 with its TOPCon Q.TRON SMART product, which was replaced with a higher power Q.TRON variant the very next month. While its efficiency remains the same, the Q.TRON module delivers 35 W of additional power over the previous one. Interestingly, despite the power increase, the cell count has reduced from 120 to 108. This is only possible when adopting larger wafer formats. The current 108-cell configuration is most likely based on the M10 wafer format, half-cell, and MBB module technology. According to the website, the module is available in the UK region. Qcells shared the 28^th rank with GCL SI until May 2025. However, with GCL’s transition to a higher efficiency band in June 2025, Qcells’ module moved to an independent 30^th position.

CECEP Solar Technology is a Chinese cell and module producer founded in 2010, operating around 4 GW of cell and 8 GW of module capacity, according to its website. The company’s TOPCon product is a High Efficiency series bifacial solar module made with 144 half-cells based on M10 n-type wafers. The product is rated with an efficiency of 22.1% and a power output of 570 W. Although the module’s specifications have undergone no changes, ranking shifts above it caused the product to move from 30^th to 31^st in June 2025, where it remains in the July edition.

The remaining 19 products in the list feature efficiencies below 22%, of which 2 are HJT-based, while the bulk, or 17, are PERC modules. The number of PERC modules has been declining recently. In July 2024, Kalyon PV’s PERC module was delisted, followed by Tongwei Solar’s product in September. October 2024 saw a module each from Astronergy and Talesun being delisted, and JinkoSolar’s module was delisted in December. In total, 5 PERC modules have been delisted over H2 2024. In January 2025, 2 PERC modules were delisted, one each from Akcome and Risen Energy. In July 2025, EGING PV’s PERC module exits our listing, as its datasheet is no longer available on the company’s website. This brings the total number of listed PERC modules down to 17 in the current edition.

Jinergy’s HJT module, which was updated in September 2023, is ranked 32^nd. Its efficiency of 21.85% is 0.17 percentage points higher than its predecessor. The featured JNHM144-475 model is a slightly larger module compared to the previous one, built with 144 cells, and thus boasts a higher power rating of 475 W. It is bifacial too, with a bifaciality of over 85%.

Meyer Burger is offering its HJT product with the same efficiency of 21.8% and a power rating of 390 W, listed 33^rd.

Several module series available today have efficiencies slightly exceeding 21.5%, as high-efficiency cell architectures are not a prerequisite for reaching that level. However, in order to design products beyond 21.7%, cell technology is key.

As shown in our recent TOP SOLAR MODULES Analysis Report, PERC in general was unable to support efficiencies above 21.6% until the end of 2023. At the time, modules with efficiencies above 21.6% usually employed cells based on high-efficiency cell architectures such as IBC, TOPCon, or HJT.

Of late, however, we have observed an increase in the number of companies reaching module efficiencies of up to 21.7% with PERC. Until November 2022, LONGi and Risen were part of this group. Canadian Solar joined the list of 21.7% efficiency PERC modules in January, Tongwei in February, DAS Solar in April, and Suntech in July 2023. However, Tongwei’s PERC module with shingled technology was delisted in September, 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 ranked 34^th to 4.

Following the order of rated power, the second module of Canadian Solar in this group, the HiKu7, is based on a 132-half-cell configuration with 210 mm wafer size and a rated power of 675 W. DAS Solar’s DAS-DH144PA module is based on a 144-cell and 182 mm wafer format. LONGi’s Hi-MO 5m is built with 144 cells of 182 mm cell size, offering 560 W of power. Suntech’s Ultra V module has a 144-half-cell design based on the 182 mm wafer format and a rated power output of 560 W. As mentioned above, Tongwei’s shingled interconnection technology-based product, with 21.7% efficiency and a power output of 430 W, has been delisted as the company is no longer offering the module.

In December 2024, JinkoSolar’s Tiger Pro module, previously ranked 39^th with an efficiency of 21.68%, was delisted due to the unavailability of its datasheet on the company’s official website. This left Akcome's iChaser PERC module, with the same efficiency of 21.68%, rated power of 560 W, and a 144-cell design using 182 mm wafers, as the sole occupant of the 39^th rank. However, in January 2025, the Akcome module was also delisted as its website was inaccessible. With Talesun’s PERC module delisted in October, the 41^st rank was shared by GCL SI, Trinasolar, and JA Solar, all with an efficiency of 21.6%. Following JinkoSolar’s delisting in December, these 3 modules moved up to the 40^th rank. By January 2025, with the reduction of 3 products, the ranking further shifted to 37^th. In the June 2025 edition, they have been pushed back to 38^th, following the entry of newer products. GCL SI and Trinasolar’s modules share a power rating of 670 W, both featuring 132 half-cells of G12 size. In contrast, JA Solar’s DeepBlue 3.0, built with 156 half-cells of M10 size, has a lower power rating of 605 W.

The next 7 products, with an efficiency of 21.57%, share the 41^st rank. Jinergy, Qn-Solar, Seraphim, Yingli, and ZNShine leverage bifacial capabilities, while modules from SolarSpace and URECO are not specified. All these products are built with 132 half-cells of the 210 mm wafer format interconnected with MBB. Not just efficiency, these 7 products have the same rated power of 670 W due to the same wafer format and the number of half-cell strips.

EGING PV’s PERC module, ranked 48^th with an efficiency of 21.56% and a rated power of 670 W, has been delisted in the July edition as mentioned above. The lowest efficiency of 21.5%, which is also the minimum threshold for inclusion in this list, is currently represented by 3 products at rank 48 – Runergy, Qcells, and CECEP Solar.

In the May 2025 edition, Qcells introduced an update with a new high-power PERC module rated at 600 W, replacing its earlier 590 W version. While the efficiency remains unchanged at 21.5%, the power upgrade positions Qcells ahead of Runergy within this group, based on the alphabetical sorting method.

Summary

The July 2025 edition of TaiyangNews’ high-efficiency module listing features 50 products from 33 companies – one less than the previous edition due to a product delisting.

The most significant change comes from JinkoSolar, which commercialized a TOPCon module with 23.32% efficiency and 630 W power. This upgrade catapulted the company from 14^th to 5^th in the rankings – the highest jump this month. With this, JinkoSolar represents the top of TOPCon products in the TOP SOLAR MODULES listing. Meanwhile, Astronergy improved its module efficiency to 23.1%, but dropped from 6^th to 7^th due to Jinko’s entry. JA Solar, which had moved up to 5^th in June with its 23.2% efficiency module, has now been pushed to 6^th. On the other hand, EGING PV’s 21.56% PERC module was delisted in July due to the unavailability of its datasheet on the company’s website, bringing the total number of listed modules to 50 and reducing the count of PERC modules to 17.

At the threshold of inclusion, the 21.5% efficiency group remains unchanged, represented by 3 modules from Qcells, Runergy, and CECEP Solar, all tied at the 48^th rank.
