Results & ChangesOur current list, compiled in the first week of December 2024, features 53 products from 33 companies. This represents a decrease of one product compared to the previous month, with the number of companies remaining constant. JinkoSolar and SolarSpace have led the most notable changes in this edition. Jinko’s PERC module has been removed from the list because its datasheet is no longer available on the company website. SolarSpace, on the other hand, has replaced its monofacial PERC module, which first appeared on the list in July 2023, with a bifacial version.The November list highlighted significant advancements in TOPCon efficiencies from 3 companies: JA Solar, Astronergy, and SolarSpace. This is the first time a TOPCon module has achieved 23% efficiency, listed under JA Solar.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 that features 24.2% efficiency. This product – AIKO-G655-MCH72M – is built with 144 half-cells of the M10 format, enabling it to reach a power rating of 655 W, 35 W higher than its predecessor. This rise in power rating is not just due to efficiency improvement, but the module size, i.e., the length, has been increased from 2,278 mm to 2,382 mm, while the width remains the same at 1,134 mm. It is a monofacial module featuring a grid-free front design for improved aesthetics and uniform appearance. AIKO has delivered third-party test lab measurement data, shipment data, and a list of projects where the module series has been used in commercial-scale installations as proof. AIKO showcased a product with up to 24.4% efficiency at SNEC & Intersolar Europe 2024, but we have yet to receive certification and shipment data from the company. AIKO also presented a very impressive 25% module at its booth, but first shipments will probably only start toward the end of the year.Maxeon Solar secured the 2nd position in May 2024, propelled by the introduction of its latest high-efficiency module Maxeon 7, which replaces the Maxeon 6 panel. Despite maintaining the same power output of 445 W, Maxeon 7 comes with 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 be noted here is 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 performance warranty of 40 years. As mentioned above, the back contact technology expert announced the new 24.1% product earlier this year – in Feb. 2024, it said that the product is available for select partners of the manufacturer in Europe, while Maxeon had plans to make these fully commercially available in Q3/2024 (see World’s Highest Commercial Solar Module Efficiency). However, we received shipment details and other data only in the May edition of the TOP SOLAR MODULES Listing.As a result of the above changes, the Hi-MO 6 module from LONGi, which was upgraded from 22.8% efficiency to 23.2% in May 2023, moved a place down to 3rd one year later in May 2024. LONGi’s product is based on its proprietary HPBC cell technology, which is essentially a back contact (BC) cell architecture. Apart from being top-class in efficiency, the Hi-MO 6 module series is also powerful. It reaches up to 600 W in the highest power class. The 144 (6 × 24) half-cell panel is a single-glass (3.2 mm) product with an anodized aluminum alloy frame, measuring 2,278 × 1,134 × 35 mm and weighing 27.5 kg. The module with up to 23.2% efficiency also features a 25-year power warranty with <1.5% power degradation in the first year and an average of 0.4% from years 2 to 25. The world’s largest vertically integrated module maker recently published a new solar lab cell efficiency record of 27.3% and announced its Hi-MO 9 panel with 24.43% efficiency (see LONGi Announces New Lab-Scale Cell Efficiency Record). LONGi also showcased it at SNEC and Intersolar Europe. However, the product does not find itself in our listing as the company has yet to provide details about the commercial status of this high-efficiency module.Huasun’s HJT module, introduced in September 2023, which moved to the 4th position in May 2024, has improved efficiency and power ratings. Until August, Huasun’s top product was listed with 22.53% efficiency and 700 W power. The Himalaya series module from Huasun is based on the G12 wafer size in a 132-half-cell configuration. The module has an efficiency of 23.02% and a power rating of 715 W, which was the highest among all listed products for a few months. The release of this product was also the first time that a module surpassed the 700 W benchmark. It is also bifacial, which, along with its high-power attribute, makes the product highly compatible with utility-scale applications. This 2 mm double-glass bifacial module has a bifaciality of 90±5%, measures 2,384 × 1,303 × 33 mm, and weighs 37.9 kg. It comes with a 15-year product warranty and a 30-year power warranty. This module improved its efficiency to 23.18% and power to 720 W in August 2024. Despite an improvement in efficiency, the module stays at the 4th rank (see Huasun’s Director of Business Development Europe Christian Comes’ presentation on State of the Art High Efficiency – Heterojunction in 2024 here, which he presented during our Solar Power Plants 2024 Conference in April).In December 2023, Tongwei Solar also started offering a 715 W module. Its HJT module, which entered the list at 4th, moved to 5th in May and has remained unchanged. Till November 2023, Tongwei was only represented in the TOPCon segment and PERC (shingled) modules. With the inclusion of this HJT product, Tongwei is among the few companies to have been featured simultaneously in all 3 different technology streams in our listing; however, this is no longer the case since its PERC module was delisted in September. 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, and an efficiency of 23.0%. Tongwei has also provided production details and a testing report for this panel (see details on Tongwei’s latest downstream plans in its presentation at a recent TaiyangNews Conference here).JA Solar’s previously best-performing TOPCon module, the JAM72D42 630/LB, which had remained unchanged since August 2023, was replaced in July 2024 by the higher efficiency JAM72D40 590/MB. This new module from the DeepBlue 4.0 series initially featured an efficiency of 22.8%, up from 22.5%, and improved it further to 23% in November 2024. As a result, JA Solar, which was ranked 12th prior to July 2024 and 6th until September, dropped to 7th in October and shares the 5th rank with Tongwei as of now. Despite having the same 144 half-cells of M10 size and higher efficiency, this module has a lower power rating of 595 W, which is 35 W less than the previous 630 W. This is obviously due to a change in wafer format. JA Solar has developed 3 different half-cell formats derived from a single wafer size of 182 x 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. While not explicitly mentioned in the datasheet, the earlier product, measuring 2,465 mm in height, seems to be built with 99.5 mm half-cell wafers. The latest 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, and weighs 31.8 kg.In March 2024, Astronergy upgraded its module efficiency from 22.65% to 22.8% and introduced a high-power, high-efficiency module from the same Astro N5 series. This bifacial panel improved its efficiency to 22.8% in November 2024.The module features 156 half-cut cells of the 182 mm wafer format and a power output of 640 W – an increase of 40 W over the previous model. This enhancement was achieved by increasing the cell count from 144 to 156, which also resulted in larger module dimensions of 2465 x 1134 x 30 mm. Despite these improvements, Astronergy's ranking has remained steady, still positioned at 7th as in the October update.Grand Sunergy, a China-based manufacturer specializing in HJT cell manufacturing, entered the renewable energy sector in 2022. The company's heterojunction (HJT) module debuted on the list in October 2024 with an efficiency of 22.86%. Following November updates from JA Solar and Astronergy, the Grand Sunergy module, which was previously ranked 6th, has dropped to 8th. 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, since July, has been represented by 5 products. It has reduced representation with only 3 products since November, following the advancements of Astronergy and JA Solar, previously part of this group, to higher efficiency. The products at this efficiency mark moved 2 places down to rank 9 last month.DMEGC’s Infinity series TOPCon module, which was last updated in April 2024 with 22.6% efficiency, was replaced with 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 previous 182 mm 144-half-cell configured module, this module has a 30 W higher rated power of 610 W and boasts an efficiency of 22.8%. This module, which moved up to 6th from 10th in the July edition, dropped to 7th in October and then to 9th in November. The module 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%. The module comes with a 30-year linear power warranty, less than 1% degradation in the first year, and a maximum of 0.4% annual degradation thereafter. Since DMEGC’s Infinity RT series module has the highest power output among all 3 modules listed at the 9th rank, it is placed first among the group.Tongwei Solar updated the efficiency of another product, its TOPCon panel, in February 2024. The module, making its entry into the list in April 2023, improved its efficiency from 22.5% to 22.8%, along with an improvement in power from 580 W to 590 W. These improvements enabled its move from 10th place to 6th. However, the entry of Grand Sunergy in October moved it back to 7th, and further updates in November pushed it down to 10th place. 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.Having maintained its 6th rank since December 2023, SPIC stepped down to 7th in October and to 9th, alongside its fellow rankers, in November 2024. While the Chinese company had been promoting a product with an efficiency of 22.3% till August 2023, it made a remarkable change in September 2023 by improving the efficiency of its top product by 0.5% absolute. Its latest Andromeda 3.0 product series comes with a top efficiency of 22.8%. The 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 bifacial module, with a bifaciality of 70% and built with 120 half-cells, has a power rating of 410 W. SPIC is offering a 30-year power warranty for this product.JinkoSolar, which moved 2 places down from 9th to 11th in the July edition and then to 12th in October, remains ranked 12th. The Tiger Neo TOPCon module is offered with a power rating of 585 W. This panel, which was last updated in September 2022, has a 144-half-cell configuration and an efficiency of 22.65%. This 2 mm dual-glass module has a bifaciality of 80±5%.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. This 580 W module is constructed with 144 half-cells using 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 43rd rank on the list. The SS9-66HS mono PERC module is now 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 new module replaces its predecessor, the Alpha Pure-R series, in our list. 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 new Alpha Pure-RX has significant improvements over the previous model, 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 this module is a couple of places down to 14th from November onwards. 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 made in Singapore and is offered with a comprehensive 25-year product and power warranty.The best module from Jolywood, the early adopter of TOPCon technology whose products have not undergone any changes technically, ranks 15th. 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 of 440 W power and 22.53% efficiency.The next group of products are all listed with 22.5% efficiency. The number of companies sharing this spot decreased from 7 to 6 in July and it remains unchanged since. However, their collective ranking fell from 15th to 16th in NovemberRisen gets the first mention among the 16th 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. The product is built with 132 half-cells, cut from the 210 mm original format, and is bifacial.Trina Solar’s Vertex N series replaced the previous Vertex S+ in the September 2023 edition. While both product groups have the same efficiency, the currently-featuring Vertex N has a high power of 700 W compared to 450 W for the former. Thus, the company’s order among the products with 22.5% efficiency went from the penultimate position up to 2nd from the top in May 2024. The TSM-NEG21C.20 is built with 210 mm wafers and 132 half-cut cells. This bifacial module, using a 2 mm glass on both sides, reaches a bifaciality of 80 ± 5%.DAS Solar's DAS-DH156NA solar module remains unchanged in design. This n-type TOPCon module features 156 half-cells and delivers a power output of 630 W. Built on the 182 mm wafer format, this bifacial half-cell module has 2 mm glass on both sides, offering up to 80% bifaciality.Canadian Solar’s TopHiKu6 TOPCon model is yet another module that offers 22.5% efficiency. The module entered our list in June 2023, replacing a bifacial product, and has an efficiency that is 0.2 percentage points higher. CS6W-580T has 144 half-cells based on the 182 mm wafer format and has a rated power of 580 W.EGing PV improved its TOPCon module efficiency slightly in May 2024. Also from the 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, listed with 22.4% efficiency until November 2023, improved its efficiency to 22.5% in December. With this change, the company moved from 21st place to 10th. This dropped to 12th in April 2024, to 14th in July, and holds the 16th rank from November. The company is another leading Chinese cell vendor that ventured into the module business not too long ago (for background, watch our interview with Runergy CTO Yang Yang). Its 2 product streams, based on TOPCon and PERC cell technologies, were featured in our review for the first time in July 2023. Runergy’s HY-DH144N8 is built with 144 half-cells of the 182 mm wafer format. The bifacial TOPCon module has an efficiency of 22.5%. However, Runergy might soon disappear from that list depending on Tongwei’s plans for the brand. Tongwei’s takeover plans for Runergy became public in August 2024 (see Tongwei Makes Offer To Acquire Majority Stake In Fellow Chinese Company).As a result of module efficiency upgrades, the 22.45% efficiency band is occupied by 2 companies since November, down from 3 in October and 4 in April. This reduction is due to the upgraded efficiency of SolarSpace’s TOPCon module in November. In the July 2024 edition, the collective ranking of these companies dropped from 19th to 20th, and to 22nd in November. Qn-Solar, a Chinese solar cell and module manufacturer, entered our listing in July 2023. Originally a project developer and EPC, the 2014-launched Shanghai-headquartered company also operates its own power plants and has been strongly expanding into the manufacturing field recently to reach 69 GW cell and 39 GW module capacity in 2023, according to the company’s website. It is promoting TOPCon modules with an efficiency of up to 22.45%, qualifying it for the shared 22nd position. Qn-Solar’s listed bifacial TOPCon product has a rated power of 580 W and is built on the 182-wafer format with 144 half-cells. Qn-Solar is also promoting a PERC module that qualifies with an efficiency of 21.57%, which earns it a place in our current listing at the 43rd position. The PERC module has an output power of 670 W.URECO is a manufacturer formed after a 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 PERC products were already part of our earlier listing, the modules based on the remaining 2 advanced cell technologies were included in our August 2023 edition. Named GLORY, the company’s TOPCon series is represented by its FBF580B8D model with an efficiency of 22.45%, which means it is the 2nd company that shares the 22nd rank. URECO’s HJT module, with a rated efficiency of 22.44%, very narrowly misses the spot by 0.01%, thus putting it 2 ranks down at 24th. 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, remains unchanged. 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, against the previous one that was based on 156 half-cells. While its power output has changed, the module’s efficiency remains the same at 22.4%, as do its other characteristics, such as TOPCon cells and bifacial module technology. This module has moved to 25th place in October from 24th and holds this rank alone. Another product from Suntech featuring since July 2023 has an efficiency of 21.7%, is placed 34th, and is among the top efficiency products in the PERC category.Kalyon PV, a vertically integrated PV manufacturer from ingot to module production headquartered in Turkey, debuted in March 2024 with its TOPCon module at rank 24, dropped to 25th in July, and to 26th in October. The company, which has 4 factories and an R&D center, 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 until July, has since been delisted.Akcome’s HJT module remains unchanged since its last update in December 2023, was down a rank to 26th in July from 25th previously, and ranks 27th since October. The company increased the efficiency of this module to 22.37% from 22.22% in December. The Ak iPower HJT module is built with 132 half-cells based on the 210 mm wafer size and is rated for 695 W of power. Betting on the high bifaciality of 90% for this dual-glass module bestowed by HJT technology, the company claims a power generation gain of 7% to 30% from the back side. Akcome also promotes a 560 W and 21.68% efficient bifacial PERC module built with 144 half-cells sliced from M10 cells. With Tongwei’s PERC module being delisted in September, Akcome’s PERC product ranking stepped up from 39 to 38. With the entry of Grand Sunergy’s new product above, this PERC product retains the 39th rank. With the delisting of JinkoSolar’s Tiger Pro PERC module, Akcome now holds this rank alone.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 made from its in-house 5 GW cell production capacity for TOPCon, while the company has 20 GW of module capacity including PERC and TOPCon. The listed module is built with 156 half-cells. The bifacial module interconnected with MBB technology has an efficiency of 22.36% and a power output of 625 W. This module is down from 27th to 28th, while another product from Yingli also earned a spot in our list in the PERC category in February 2022, which is now ranked 44th.Part of the vertically integrated GCL Group, which is a global leader in silicon production for the solar industry, GCL Integration (GCL-Si) is offering solar modules and battery storage products as well as full PV project solutions (for details on GCL Group, watch our interview with Group Chairman Gongshan Zhu). In the July 2023 edition, we included 2 module products from GCL-SI. Both the TOPCon and PERC modules of the company are listed under the same series – GCL GEMINI. However, the April 2024 list replaced the TOPCon GCL GEMINI series with GCL LOTUS without altering the key specs of the product, while the PERC range remained under the GCL GEMINI series. The most efficient product of this series, the GCL_NT10/72GDF, represents the company’s TOPCon range and has an efficiency of 22.3% and a power output of 575 W. The bifacial module is designed with 144 half-cut cells based on the 182 mm wafer format. In October, this module moved from 28th to 29th to share the rank with Qcells. This remains unchanged in this edition as well. The number of companies sharing this position dropped from 3 to 2 in July, with REC’s move up.Qcells, which re-entered our list in February 2024 with its TOPCon Q.TRON SMART product, which was replaced with a higher power Q.TRON variant already in March 2024. 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.CECEP Solar Technology Zhenjiang is a Chinese cell and module producer founded in 2010 that operates around 4 GW of cell and 8 GW of module capacity, according to its website. CECEP’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. This module has had no changes to its specifications and ranks 31st.The remaining 22 products listed are below 22%, of which 2 are HJT-based while the bulk are PERC modules. The number of PERC modules has been declining recently. In July, Kalyon PV’s PERC module, and thus the company itself, was delisted, followed by Tongwei Solar in September. October saw a module each from Astronergy and Talesun being delisted, and JinkoSolar’s module was delisted this month. In total, 5 PERC modules have been delisted over the last 6 months.Jinergy’s HJT module, which was updated in September 2023, is ranked 32nd. Its efficiency of 21.85% is 0.17 percentage points higher than the previously listed product. Not just efficiency, the featured JNHM144-475 is a slightly larger module compared to the previous one, built with 144 cells, and thus has 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 at the 33rd position since last month.There are several module series available today with efficiencies slightly exceeding 21.5%, as high-efficiency cell architectures are not a must to reach that level, but 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 not able to support efficiencies above 21.6% until the end of last year. 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 – and all of them are ranked #34. However, Tongwei’s PERC module with shingled technology was delisted in September, reducing the number of companies ranked #33 at the time from 6 to 5. Following the order of rated power, the second module of Canadian Solar in this list, the HiKu7, is based on a 132 half-cell configuration with 210 mm wafer size and a rated power of 675 W. Risen Energy’s TITAN module is built with 132 half-cells of the 210 mm wafer format for 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 module 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 Solar’s shingled interconnection technology-based product with 21.7% efficiency and a power output of 430 W has been delisted as the company is not offering the module anymore.If rounded, the next 2 products would also reach 21.7%, but the companies – Akcome and JinkoSolar – chose not to do so in their spec sheets. Thus, they continue to share the 39th rank, which was 38th previously. JinkoSolar’s Tiger Pro is a module with 21.68% efficiency based on a 144-cell configuration, resulting in a rated output of 560 W. Akcome has a bifacial product with the same number of cells, cell format and output as Jinko.Another change in this edition involves JinkoSolar, whose Tiger Pro module, previously ranked 39th with an efficiency of 21.68%, has been delisted due to the unavailability of its datasheet on the company’s official website. This leaves Akcome's iChaser PERC module as the sole occupant of the 39th rank. The Akcome module features an efficiency of 21.68%, a rated power output of 560 W, and is constructed with 144 cells in the 182 mm wafer format. With Talesun’s PERC module delisted in October, the 41st rank is now shared by GCL SI, Trinasolar, and JA Solar, all listed with an efficiency of 21.6%. As a result of this change, the 3 modules previously ranked 41st have moved up to 40th. The products from GCL Si and Trinasolar share a power rating of 670 W due to the same 132 half-cells of G12 size. However, JA Solar’s DeepBlue 3.0, built with M10-sized 156 half-cells, has a lower power rating of 605 W.The next 7 products, with an efficiency of 21.57%, share the 43rd . 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 count of half-cell strips.EGing PV’s PERC product is the lone beholder of the current 50th rank, moving up from the 53rd place it had slipped to in April. It has a lower efficiency of 21.56%, but the power rating of 670 W is the same as the products from the group above.The lowest efficiency of 21.5%, which is also the minimum criterion to be included in this list, is represented by 3 products at rank 51 – Runergy, Qcells and CECEP. Astronergy’s longstanding PERC module, which entered our listing in September 2023, was delisted in October 2024.
