Key Takeaways
The November 2025 edition features 47 high-efficiency modules from 33 manufacturers, compared to 49 modules and 34 companies in the previous (October) edition
Trinasolar’s Vertex N series features a new model in our listing, TSM-NEG19RC.20, with an improved efficiency of 23.7%, boosting its ranking from 9th to 3rd
Maxeon's BC modules and a PERC product from DAS Solar have been delisted from the current listing
Following a host of efficiency improvements in recent months, the November edition presents one new efficiency improvement and the delisting of couple of products from the TaiyangNews TOP SOLAR MODULES ranking. These updates have resulted in a rearrangement of the rankings for several products in this month’s listing, especially Rank 10 and below.
The November edition features 47 commercially available high-efficiency modules from 33 manufacturers. Compared to the previous edition, the total product count has decreased by 2, and the number of companies by 1.
The most notable change in the November edition is Trinasolar has bumped up the efficiency of its TOPCon module from 23.2% to 23.7%, significantly improving its ranking from 9th to 3rd. With this, Trinasolar not only tops the TOPCon segment but also earns a spot among the top 3 not only for itself but also for TOPCon technology. This shift is also influenced by the delisting of Maxeon, previously ranked 3rd with its Maxeon 7 series.
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, which was started in 2023 and 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 Badge of Excellence 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 ways 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 was 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. 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 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 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 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.
Results & Changes
The latest edition of TaiyangNews’ Top Solar Modules, compiled in early November 2025, features 47 high-efficiency products – 2 fewer than in the previous month – from 33 companies, with Maxeon delisted due to product unavailability.
A significant increase in Trinasolar’s TOPCon Vertex N module efficiency has elevated its ranking from 9th to 3rd, placing it among the Top 3, and making it the top among TOPCon. Trina’s updated module efficiency is 23.7%, with a rated power of 640 W.
On the downside, 2 modules have been delisted in this edition. The first is Maxeon’s BC module, as its datasheet is no longer available on the company’s website. DAS Solar’s PERC product has also been delisted due to the unavailability of product specs; the company is most likely following in the footsteps of many leading companies that are withdrawing from PERC technology. These changes resulted in a reordering of the overall rankings in the November edition of our TOP SOLAR MODULES listing.
What has not changed is that the top 2 ranks are occupied by AIKO and LONGi.
AIKO has made the top seat its own ever since its entry into the list in March 2023, with its ABC series module boasting an efficiency of 23.6% at the time. It further cemented its position 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 dominance with the latest Comet 2U series, featuring 24.2% efficiency. In June 2025, AIKO 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 3rd 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 2nd 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 surpassed Maxeon and has held sole possession of the 2nd place ever since. This product remains unchanged in the current 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, which 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, 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, rated at 24.4% efficiency and 660 W of power, under the same Hi-MO 9 series.
Trinasolar achieved a significant upgrade this month, improving its Vertex N series module efficiency from 23.2% to 23.7%. The model, TSM-NEG19RC.20, is based on 210R wafers, unlike Trina’s previous listing, which was based on a 210 mm side length wafer. This latest module has a power rating of 640 W.
The Vertex N series replaced the previous Vertex S+ in September 2023. Back then, while both product groups had the same efficiency, the former offered a higher power output of 700 W compared to 450 W for the latter. As a result, the company’s ranking among products with 22.5% efficiency rose from the penultimate position to 2nd from the top in this group in May 2024. It went on to achieve 23% in May 2025, and then 23.2% in October 2025.
The TSM-NEG19RC.20 module is built with 132 half-cells based on 210R wafers. This bifacial module uses 2 mm glass on both sides and offers a bifaciality of 80±5%. Keeping these core specifications unchanged compared to the previously listed TSM-NEG21C.20, the module achieves improved efficiency through the rectangular wafer format. With this new product, Trinasolar has surpassed other TOPCon players, achieving the highest module efficiency of 23.7%.
JinkoSolar first commercialized its Tiger Neo (JKM625–635N–66HL4M-BDV) TOPCon module in July 2025, debuting 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 to the top of the listed TOPCon modules.
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 the October edition, marking a significant milestone, as it was the first time a TOPCon module surpassed the top HJT efficiency benchmark within the TaiyangNews TOP SOLAR MODULES rankings. In the current edition, Jinko is surpassed by Trina’s TOPCon module. However, JinkoSolar remains at Rank 4 with Trina replacing Maxeon at Rank 3.
Looking back, JinkoSolar’s trajectory over the past year illustrates how quickly its module efficiency has advanced: the company dropped from 9th to 11th in the July 2024 edition, slipped further to 12th in October, to 13th in May 2025, then to 14th in June 2025, before its major leap to 5th in July 2025 following the introduction of the Tiger Neo series.
This bifacial module is built with 132 half-cells based on n-type monocrystalline TOPCon architecture and incorporates the company’s HOT 3.0 cell design for enhanced light trapping, current collection, and reliability. It 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.
Huasun’s HJT module, introduced in September 2023, moved up to the 4th position in May 2024, thanks 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. The first to surpass the 700 W threshold on our list, the product later improved 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 raised the bar in the June 2025 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 a 30-year power warranty.
Although its specifications remained unchanged in the October 2025 edition, the product’s ranking stepped down to a joint 5th, following JinkoSolar’s rise to 4th place. Since then, Huasun shares the 23.5% efficiency band with DMEGC Solar and JA Solar, as a result of the latter pair improving the top efficiencies of their commercial offerings.
DMEGC Solar achieved a notable upgrade in October, improving its Infinity RT TOPCon module to 23.5% efficiency and a 635 W power output from the previous 23% and 620 W. The company’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 6th from 10th in July 2024, this module dropped to 7th in October and then to 9th in November 2024. An improvement in its efficiency 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, the product upgrade elevated DMEGC Solar back into the Top 5, sharing the 23.5% efficiency band with Huasun and JA Solar. 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%. DMEGC’s position remains unchanged in the current edition.
JA Solar improved its TOPCon module efficiency in October from 23.3% to 23.5%, also raising the power output from 630 W to 635 W. JA Solar commercialized a high-efficiency TOPCon module – JAM66D45 630/LB – with an efficiency of 23.3% in September 2025. This follows the JAM72D40 series, which entered the list in July 2024 at 22.8% efficiency, was raised to 23.0% in November 2024, and further improved to 23.2% in June 2025. Before that, JA Solar had been represented by the JAM72D42 630/LB, which had remained unchanged since August 2023 after replacing the earlier JAM66D45 630/LB.
The currently featured JAM66D45 635/LB measures 2,382 × 1,134 × 30 mm and weighs about 33.1 kg. It is a bifacial double-glass module with a bifaciality of 80±10%, consisting of 66 full cells (132 half-cells) based on JA Solar’s rectangular M10 wafer platform. The module is interconnected with 16 busbars and is rated for a power output of 635 W at 23.5% efficiency. Compared to the previously featured JAM72D40 600/MB, which adopted the smaller 94 mm half-cell format in a shorter 2,278 mm, 72-full-cell (144 half-cell) module, the current product employs the larger 99.5 mm half-cell format. While these are also the features of the previously listed module, the current product features an improved efficiency of 23.5%. With this, JA Solar has become a part of the 23.5% efficiency club, sharing the 5th rank with Huasun and DMEGC Solar, which remains unchanged in this edition.
Astronergy improved its module efficiency from 23.1% to 23.3% in September 2025. 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).
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 7th to 5th. The bifacial TOPCon module is composed of 132 half-cut cells based on 182 mm rectangular wafers. At 2,382 mm, the N7 module is slightly shorter in length compared to the previous model, 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 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 module mentioned above. In September, with efficiency reaching 23.3%, Astronergy reclaimed the 6th place. However, in the October 2025 edition, it moved a step down to 8th, a position it holds in the November 2025 edition.
With Trinasolar moving up from 9th to replace Maxeon at 3rd, rankings 10th and beyond have moved up by one rank. The first in the list is DAS Solar, which has moved from 10th previously to 9th in this edition.
DAS Solar first appeared in the TOP SOLAR MODULES list in October 2022 with a product featuring 570 W of power and 22.1% efficiency. This was followed by several quick updates: in April 2023, the company introduced the DAS-DH08NA with 435 W power and 22.3% efficiency; in July 2023, the DAS-DH144NA reached 580 W of power and 22.4% efficiency; and in August 2023, the DAS-DH156NA was launched with 630 W power and 22.5% efficiency. DH156NA then remained in the rankings for almost 2 years before being replaced in September 2025 by the new, higher-efficiency (23.1%) DAS-DH132NE. With this update, DAS Solar’s ranking catapulted from 19th to 8th. In the October 2025 edition, while its efficiency and power ratings remain unchanged, the company ranked 10th.
DAH Solar, a new entrant in the TOP SOLAR MODULES list in September 2025, made its debut at the 9th rank. Headquartered in China, the company is recognized for its balcony solar kits and its patented Full-Screen module design, which eliminates the front frame to reduce dust accumulation and improve effective power generation in outdoor conditions. The debut product is a Full-Screen TOPCon module that achieves 23.02% efficiency, reaching a maximum power of 595 W. Built on the 182 mm wafer format in a 132 half-cell configuration, the module measures 2,278 × 1,134 × 30 mm and weighs about 30.7 kg. It features a dual-glass construction, offers a bifaciality of around 80%, and comes with a 30-year linear power warranty. In the October 2025 edition, following the above efficiency upgrades, DAH Solar’s ranking moved to 11th. In this latest edition, while its specifications remain unchanged, its ranking improves to 10th due to the changes mentioned above.
With the latest round of module upgrades, most manufacturers have moved beyond the 23% efficiency range. The 23% band, previously shared by Trinasolar, Tongwei Solar, and DMEGC Solar, is now represented solely by Tongwei Solar, which holds the 11th rank in the current edition.
In December 2023, Tongwei Solar also started offering a 715 W HJT module, which entered the list ranked 4th. It then moved to 5th in May 2024 and to 6th in June 2025. Till November 2023, Tongwei was only represented in the TOPCon and PERC (shingled) segments. With the inclusion of this HJT product, Tongwei became one of the few companies to have featured simultaneously in all 3 different technology streams in our listing. However, the delisting of its PERC module in September 2024 narrowed 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%. This module now ranks 11th. 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, and they can be accessed here.
Jetion Solar, which held the 13th position since September 2025, has moved to 12th in the current listing.
Established in 2004 and operating under the China National Building Materials Group Corporation (CNBM), Jetion 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 in June 2025 at the 10th 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 11th in the July 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 6th. Subsequent efficiency updates from JA Solar and Astronergy in November 2024 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, the module moved down to 10th. Jetion Solar’s entry in June 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 edition, it moved to 14th rank, and occupies 13th rank in the current edition. The company’s 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, weighing 38.5±0.5 kg. It features a bifaciality of 85% and is supported by a 30-year linear power warranty.
The next efficiency band on the list is 22.8%. Represented by 5 products in July 2024, the number dropped to 3 in November 2024 after Astronergy and JA Solar advanced to higher-efficiency groups. In July 2025, DMEGC’s move to the 23% class further reduced the count to 2. There has also been a steady decline in the band’s rank – from 9th in November 2024, to 10th in March 2025, 11th in May, 12th in June, 13th in July, and further down to 15th in September 2025. Although it has improved to 14th rank in the current edition, it is not really due to technological advancements, but rather a result of reshuffling at the top.
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% and power from 580 W to 590 W. These improvements enabled its move from 10th place to 6th. However, Grand Sunergy’s entry in October 2024 shifted it down to 7th, with further declines to 10th in November and 11th following Trinasolar’s May update. In June 2025, it was pushed to 12th, to 13th in July 2025, and to a further 15th in September 2025. It currently occupies Rank 14. The product is designed with a TNC cell type and an anodized aluminum alloy frame, and features a 30-year linear power output warranty. This product is built with 144 half-cells of the G12 wafer format.
Ranked 6th from December 2023 until September 2024, SPIC moved down to 7th in October and to 9th in November, alongside its fellow rankers. With subsequent advancements by LONGi, Astronergy, and DMEGC Solar, the rankings of Tongwei and SPIC both slipped to 10th in March, then to 11th in May, 12th in June, to 13th in the July 2025 edition, and to 15th in September, and currently to 14th.
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 has a rated top efficiency of 22.8%. 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 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 2025 and October editions. It now ranks 16th in the current edition. This 580 W module is composed of 144 half-cells based on the 182 mm wafer format. Additionally, SolarSpace’s Lumina I, a PERC module with an efficiency of 21.57%, is one of 6 products tied for the 39th rank on the list. In December 2024, the company’s SS9-66HS mono-PERC module was replaced with the SS9-66HD bifacial PERC module.
In October 2025, Canadian Solar improved the efficiency of its existing TopHiKu6 TOPCon module from 22.5% to 22.6%, along with a corresponding power increase from 580 W to 585 W. As a result of this improvement, the company’s ranking also improved from 21st to 18th, sharing the rank with REC Solar. Currently, both of them rank 17th in the listing.
The TopHiKu6 series first entered the TOP SOLAR MODULES listing in June 2023, with the CS6W-580T variant achieving 22.5% efficiency, replacing an earlier 22.3% efficiency bifacial module. The CS6W-585T module comprises 144 half-cells based on the 182 mm wafer format and a bifacial configuration.
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 27th to 12th and then a couple of places down to 14th in November. It slid to 15th in May, to 16th in June, and 2 places down to 18th as of September 2025. In the current edition, REC shares its rank with Canadian Solar at 17th.
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 28th to 29th, sharing its rank with Qcells. GCL regained the 28th 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 a 210 mm wafer format with 132 cells. It delivers a rated power of 700 W and achieves a module efficiency of 22.53%. With this upgrade, the company’s ranking improved significantly, jumping from 28th to 17th. In the September 2025 edition, this module moved to 19th, and it went down another rank to 20th in October 2025. In the current edition, the product is up a place to 19th. The design incorporates a multi-busbar (MBB) architecture, and the product is confirmed to be commercially available. GCL SI also lists a PERC product, which is ranked 38th.
Jolywood, one of the early adopters of TOPCon technology, currently shares the 19th rank with GCL SI. 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 at 22.5% efficiency saw the number of companies sharing this spot considerably reduced over time, 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 higher 23% efficiency band further reduced the count to 5, leading to another drop in the group ranking to 17th. In June, the group’s position slipped further to 19th. In September 2025, DAS Solar’s improvement reduced the number of companies to 4, with the group ranked 21st. In the October 2025 edition, following Canadian Solar’s efficiency improvement to 22.6%, the number of companies in the 22.5% band further decreased to 3, and the collective group ranked 22nd. In the current edition, due to Maxeon’s product delisting, the group’s rank has moved to 21st.
Risen gets the first mention among the 21st rankers, a group that is structured according to power first and, if equal, in alphabetical order. Risen Energy’s Hyper-ion HJT module, which was included in June 2023, has an efficiency of 22.5%, corresponding to a high rated power of 700 W. This bifacial product consists of 132 half-cells, cut from the original 210 mm format.
EGING PV improved its TOPCon module efficiency slightly in May 2024. Also from its Star Pro series, the company’s best TOPCon product has an efficiency of 22.5%, increased from 22.45%. This bifacial module, comprising 144 half-cells of the 182 mm wafer format, maintains its power rating at 580 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 21st to 10th place. The ranking gradually declined thereafter, dropping to 12th in April 2024, 14th in July, and to 17th in November. It then moved down to 19th in June 2025, to 21st in September, to 22nd in October, and now improved to 21st in November 2025.
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 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 upgrades, the 22.45% efficiency band, at a collective rank of 24, has seen a drop in product 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 19th to 20th, and then to 22nd in November 2024, with SolarSpace’s TOPCon module moving up that month. In June 2025, its ranking dropped to 24th and further to 25th in September 2025.
In the October 2025 edition, this trend continued as Qn-SOLAR’s TOPCon module was delisted; its datasheet was no longer available, and no commercialization details have been provided for modules with higher efficiencies. As a result, the 22.45% efficiency level is now represented by only 1 product from URECO.
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 places it at 24th rank. In October 2025, following the delisting of Qn-SOLAR, this module became the sole representative of the 22.45% efficiency band. URECO’s HJT module, with a rated efficiency of 22.44%, very narrowly misses the spot by 0.01%. 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. This module is listed 1 rank below its peer, at 25th. Previously, its overall rank went up by 1 due to the delisting of Qn-SOLAR. All the products down the list from here have improved their ranking due to the exclusion of Qn-SOLAR’s TOPCon product.
Yingli Solar is one of the early adopters of n-type wafer-based cell architectures. It has 5 GW of cell production capacity for TOPCon and 20 GW of module capacity for PERC and TOPCon. Yingli entered the list in November 2023 with its PANDA 3.0 PRO, a TOPCon module product that remains unaltered since then. The listed TOPCon bifacial module, comprising 156 half-cells with MBB interconnection, has been rated at 22.36% efficiency and 625 W of power. 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. Currently, it holds 26th place. 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. This product now holds the 36th rank in the listing.
Suntech’s module, which saw a change in April 2024, remains unaltered 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 consists 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 24th to 25th in October 2024, to 27th in June 2025, further down to 28th in September 2025, back to 27th rank in October 2025, and up another rank in the November 2025 edition. Another Suntech product, a PERC module first listed in July 2023, boasts an efficiency of 21.7% and ranks 33rd, 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 25th in July, and then 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. Currently, the module ranks 28th in the listing, with 22.38% efficiency.
With 4 factories and an R&D center, the company commenced production in 2019. Its TOPCon module, featuring 22.38% efficiency and 580 W power output, utilizes 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.
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 at 22.3%, 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 28th 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 30th position, followed by another move to 31st in September 2025. In the October 2025 edition, it regained its June position at 30th. In the November 2025 edition, the product ranks 29th in the listing.
CECEP Solar Technology is a Chinese cell and module producer founded in 2010, operating capacities of around 4 GW for cells and 8 GW for modules, 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 seen no changes, ranking shifts among higher-efficiency modules have impacted its placement in the overall list. After moving from 30th to 31st in June 2025 and further to 32nd in September 2025, the module rose back to 31st in October 2025. With the exclusion of products above, its rank further improves to 30th in November 2025.
Below 22% Efficiency Group:
The remaining 17 products in the list feature efficiencies below 22%, of which 2 are HJT-based, while the bulk, or 15, 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. In October 2024, a module each from Astronergy and Talesun delisted, while JinkoSolar’s module was delisted in December. In total, 5 PERC modules were 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 was removed from our listing, as its datasheet is no longer available on the company’s website. With JA Solar’s delisting of its PERC product in October 2025 and DAS Solar’s PERC module in November 2025, the total count of PERC modules now stands at 15, 2 down from 17 in the previous edition.
Jinergy’s HJT module, which was updated in September 2023, is now ranked 31st. 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 32nd.
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 achieving 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 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 ranked 34th to 4. In the current edition, the 21.7% efficiency group is further narrowed to 3, as DAS Solar has discontinued its PERC product. While the group’s rank improved to 33 in this edition, product rankings 38th onward in the previous edition have improved by 2 positions in this edition.
Following the order of rated power, the second module in this group, the HiKu7 from Canadian Solar, 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, was delisted since the company is no longer offering the module.
In December 2024, JinkoSolar’s Tiger Pro module, previously ranked 39th 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 39th 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 41st 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 40th. By January 2025, with the reduction of 3 products, their ranking further shifted to 37th. In the June 2025 edition, they were pushed to 38th, and slipped one more step to 39th in September 2025 as newer, higher-efficiency modules entered the list. In the October 2025 edition, with the delisting of JA Solar’s PERC module, this efficiency band was jointly represented by GCL SI, Trinasolar, and Yingli Solar, ranking 38th. In the current edition, this trio shares the 36th rank. In the August 2025 edition, Yingli Solar’s PERC module efficiency improved slightly from 21.57% to 21.6%, thus sharing the rank with the other 2 companies. GCL SI, Trinasolar, and Yingli modules share a power rating of 670 W, all featuring 132 half-cells of G12 size.
With Yingli’s move up, the number of modules representing 21.57% efficiency reduced from 7 to 6. Ranked 41st at the time, all these products moved down a position to 42nd in August, to 43rd in September 2025, again to 41st in October 2025, and to 39th position in November 2025. Jinergy, Qn-SOLAR, Seraphim, 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 6 products have the same rated power of 670 W due to the same wafer format and the number of half-cell strips.
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 45 – Runergy, CECEP, and Qcells.
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 November 2025 edition of TaiyangNews’ TOP SOLAR MODULES presents several key changes, which are reflected in the overall rankings across all efficiency groups. This edition also features a slightly shorter list of top modules due to the delisting of 2 products – Maxeon’s back-contact module, ranked 3rd in the previous edition, and DAS Solar’s PERC product, ranked 34th in the previous edition.
The current edition also features a considerable upgrade from Trinasolar, which underscores TOPCon technology’s dominance – not only in manufacturing but also in terms of commercial module efficiency potential. Trinasolar provided the proof of commercialization for its latest Vertex N series, labeled TSM-NEG19RC.20, featuring an efficiency of 23.7% and a module power of 640 W. This not only earned the top spot for the company among the TOPCon products, but also marked the entry of TOPCon technology into the top 3 club. That means Top 3, which has been a BC league, now shares space with TOPCon.
Meanwhile, the share of PERC modules continues to decline as manufacturers retire legacy products in favor of n-type architectures. Following the delisting of DAS Solar’s PERC module, the sub-22% efficiency group now comprises 17 products – 15 PERC and 2 HJT. The number of companies listed in TOP SOLAR MODULES is now 33, and the product count is 47. What has not changed is that the top 2 ranks are still represented by BC – namely AIKO and LONGi – and Huasun’s HJT module continues to offer the highest power in the list at 730 W.
