In May, TaiyangNews reported record-breaking updates in the top solar modules. The June edition, based on research conducted before the world's largest solar shows SNEC and Smarter E / Intersolar Europe take place, remains unchanged from last month. The list still features 57 products from 33 companies, with no alterations in the rankings. It is made up of 4 IBC, 8 HJT, 20 TOPCon, and 25 PERC products. After nearly about a year of AIKO creating history by attaining a landmark efficiency of 24% for commercial modules, the Chinese company broke its own record once again in May by commercializing yet another module with an even higher efficiency of 24.2% and a power of 655 W. This improvement, though, has no impact on the current top modules list as AIKO was already at the top and, thus, retained its 1st rank. Like the previous model, its latest Comet series is also based on back-contact cell architecture.
Another very interesting aspect of last month's listing was that the pioneer of back contact technology, Maxeon Solar, commercialized a 24.1% efficient module with a power output of 445 W. While the Maxeon 7 module series was publicly introduced a few months ago, we have received the proof of commercialization asked for in the May edition. As a result, Maxeon Solar is up in the 2nd position from 4th previously.
Looking back at the May edition, it's important to note that the changes at the very top influenced the rankings of several products, particularly the top 5. While LONGi has shifted from rank 2 to 3, Huasun has moved from 3rd to 4th, and Tongwei Solar from 4th to 5th. These rankings remain unchanged in June.
Aside from AIKO and Maxeon, there was also another change in the May edition – EGing PV's TOPCon module is now listed with a slightly higher efficiency of 0.05%, while its power remains unchanged at 580 W.
Despite the May changes, the statistics of our TOP SOLAR MODULES LISTING have not changed from the previous month, showcasing 57 products from 33 companies.
For more details on the different modules, please check the Results & Changes section below, following the Background and Methodology chapters.
Before diving into the details, we reiterate the launch of our Excellence Badge scheme announced in December 2023. Manufacturers who have featured in the TOP 10 for at least 6 months within a calendar year are eligible to apply for the badge. A total of 8 companies – AIKO Solar, Huasun, JA Solar, JinkoSolar, LONGi, Risen, Tongwei Solar and Trina Solar – have already availed the badge, which is also indicated in the efficiency table below.
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 covering the efficiency progress of solar modules through its annual reports on Advanced Module Technologies starting in 2017. We also cover cell/module technology updates in our High Efficiency Solar Technologies Conference once year; the most recent took place in Dec. 2023 (access the presentations here). However, in the quickly changing solar sector, a lot happens over the course of a year, which is also covered in the many events we are organizing on different topics (see latest on Solar Power Plants in April 2024).
To put these information pieces together and keep our readers updated about the global module efficiency progress more frequently, TaiyangNews started publishing this monthly column on commercial TOP SOLAR MODULES at the beginning of 2022. TaiyangNews has also published several reports presenting the analysis of this monthly list – the latest in March 2024 (see TOP SOLAR MODULES 2023).
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 the minimum efficiency of 21.5% as the criterion to feature in the list. We have listed only commercially-available top modules from each cell technology stream of one module maker. For example, if a company is offering 2 different product streams based on PERC technology 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 the 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 an 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. A module that has the complete data sheet listed on its manufacturer's website is the first step towards being considered a commercially-available product. As such, the efficiency and power data listed here are taken from the data sheet 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 having a data sheet online 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
Our current list, compiled as of the first week of June 2024, includes 57 products that meet our criteria, from 33 companies. The changes observed in the May edition have remained consistent in the June edition, with no alterations in the rankings of the listed products. Since AIKO entered the list in March 2023 with its ABC series module featuring an efficiency of 23.6%, the company has retained the top seat. AIKO broke its own record and created history in June 2023 with another ABC series module by reaching the benchmark efficiency of 24% for a commercial module. Again, in May, AIKO continued its legacy with its latest Comet 2U series that features 24.2% efficiency. The particular product – AIKO-G655-MCH72M – is built with 144 cells of M10 format, enabling the product 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.
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 plans to make these fully commercially available in Q3/2024 (see World's Highest Commercial Solar Module Efficiency). But we received details about shipments and other data only for May edition of the TOP SOLAR MODULES LISTING.
As a result of the above changes, the Hi-MO 6 module from LONGi, which was updated in May 2023 – up from 22.8% efficiency to 23.2% – , one year later, in May 2024,moved a place down to 3rd. LONGi's product is based on its proprietary HPBC cell technology, which is essentially a back contact 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 x 24) half-cell panel is a single-glass (3.2 mm) product with an anodized aluminum alloy frame, measuring 2,278 x 1,134 x 35 mm and a weight of 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. It remains to be seen, when LONGi's higher efficient product will be available – the world's largest vertically integrated module maker recently published a new solar lab I 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). However, the product does not find itself in our listing as 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 in May 2024 to the 4th position, remains the same. Until August, Huasun 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. (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 that feature 3 times in our list, meaning in 3 different technology streams. Tongwei's HJT module is built with 132 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).
Astronergy, which updated its module efficiency from 22.65% to 22.8% in March 2024, remains in the 6th position. The company has also improved the module's power output from 585 W to 590 W. This bifacial panel from Astronergy is built with 144 half-cut cells of the 182 mm wafer format. This update lifted its product to 6th place from 8th, thus sharing the rank with Tongwei Solar and SPIC (see below).
Tongwei Solar updated the efficiency of another product, its TOPCon panel, in February. 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. The product is designed with a TNC cell type, an anodized aluminum alloy frame and features a linear warranty of 30 years for power output. This product is built with 144 half-cells of the G12 wafer format.
SPIC shares the 6th rank, a place it has been in for some time now. 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 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's module has not undergone any changes and remains at its 9th position. Jinko's Tiger Neo TOPCon module is offered with a power rating of 585 W. This panel has a 144 half-cell configuration and an efficiency of 22.65%. This 2 mm dual glass module has a bifaciality of 80±5%. This module is last updated in September 2022.
DMEGC's TOPCon product, which was last updated from 22.4% to 22.5% in January 2024, has again seen a 0.1 percentage point improvement to 22.6% in April 2024. As a result, its ranking has also improved from 11th place to 10th. The module's power rating has also increased from 580 W to 585 W. This bifacial module is designed with 144 half-cells based on the 182 mm wafer format.
The best module from Jolywood, the early adopter of TOPCon technology whose products have not undergone any changes technically and ranks 11th. However, the product slipped a rank by one position in April 2024. 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.
In the latest rankings, 7 companies share the next efficiency level of 22.5%, placing them jointly at the 12th position. The count has increased by 1 in May 2024, with EGing PV improving the efficiency of its TOPCon module to 22.5% from 22.45%.
Risen gets the first mention in the group sharing the 12th place, which is structured according to power first and, if equal, an alphabetical order is applied. 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 the 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 ranked 12th (22.5% efficiency) has gone up from the penultimate position to 2nd 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 is also listed at 12th. This n-type TOPCon solar module remains unchanged, featuring 156 half-cells and 630 W power.
JA Solar's TOPCon listing saw a change in power ratings in the August 2023 edition. The JAM72D42 630/LB has a higher power rating of 630 W compared to the 530 W JAM72D40 580/GB product, but its efficiency is the same at 22.5%, and thus ranked 12th. It is a bifacial double-glass module with a bifaciality of 80 ±10% and is built with 144 half-cells of the G12 size and 16 busbars. As to the physical characteristics, the module measures 2,465 x 1,134 x 35 mm and weighs 34.6 kg.
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.
EGing PV improved its TOPCOn module efficiency slightly in May 2024. Also from the Star Pro series, the company's updated 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 the 21st place to 10th, and in April 2024 down to 12th. The company is another leading Chinese cell vendor that ventured into the module business not 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 in the 182 mm wafer format. The bifacial TOPCon module has an efficiency of 22.5%.
The above changes in May 2024, however, have affected the ranking of the next efficiency band of 22.45%. This batch is now represented by 3 companies, compared to 4 until April, and their collective ranking has also slipped by a rank from 18th to 19th with EGing PV moving up to the next efficiency level.
Qn-Solar, a Chinese solar cell and module manufacturer, entered our list 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 19th 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 inclusion in our current listing at the 46th position. The PERC module has an output power of 670 W.
SolarSpace also belongs to the category of leading cell manufacturers venturing into module making, and is represented with both PERC and TOPCon modules in our listing. Having entered our rankings in July 2023, its Lumina II TOPCon module was upgraded in December to a high-efficiency variant, increasing its efficiency from 22.02% to 22.45%, which has remained unchanged so far. The 580 W module is built with 144 half-cells based on the 182 mm wafer format and has an efficiency of 22.45%. This module shares the 19th place with 3 others. Lumina I from SolarSpace is a PERC module with 21.57% efficiency and is one among the 7 products sharing the 46th rank on the list.
URECO is a manufacturer formed after a merger of 3 leading Taiwanese cell manufacturers – Neo Solar Power, Gintech and Solartec. The company has products on offer that are 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 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 4th company that shares the 19th rank. URECO's HJT module, with a rated efficiency of 22.44%, very narrowly misses the spot by 0.01%, putting it 4 ranks down at #22 in March 2024, which has also not changed this June. Called GLORY HELLO, the module is built with 120 half-cells using 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 powered 605 W Ultra V Pro last month. 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%, meaning it still holds the 23rd rank all alone. Even the other characteristics remain the same such as TOPCon cells and bifacial module technology as the previous model. Another product from Suntech featuring since July 2023 has an efficiency of 21.7%, is placed 33rd 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 at 24th and remains unchanged. The company, which has 4 factories and an R&D center, commenced production in 2019. Its TOPCon module, notable for its 22.38% efficiency and 580 W power output, features M10 half-cut cell technology and a bifacial module design. Additionally, another module from Kalyon, listed in the PERC category, achieves an efficiency of 21.61% with a power output of 380 W, placing it 41st in the ranking.
Akcome's HJT module remains unchanged at the 25th position, in fact since its last update in December 2023. 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 a power of 695 W. 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. This PERC product shares the 39th rank with JinkoSolar's Tiger Pro PERC module which has the same efficiency.
Yingli Solar, one of the early adopters of cell architectures based on n-type wafers, 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 placed 26th, while another product from Yingli also earned a spot in our list in the PERC category in February 2022 , ranked 46th in March 2024.
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. The company has renamed its GCL GEMINI series as GCL LOTUS without altering the key specs of the product. 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.
Qcells reentered our list in February 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. Qcells shares the 27th rank with the existing products from GCL-Si and REC.
REC's top HJT module offered commercially hasn't seen any change from 2023 to date. The Singapore-based manufacturer's Alpha Pure-R series HJT product is available with an unaltered efficiency of up to 22.3% and 430 W module power.
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 ranks 30th.
The remaining 27 products listed are below 22%, of which 2 are based on HJT while the bulk are PERC modules.
Jinergy's HJT module, which was updated in September 2023, now ranks 31st. 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, now listed at the 32nd position.
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%, the cell technology is key.
As shown in our recent TOP SOLAR MODULES 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 #33. 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. Tongwei Solar, which had a 21.5% efficiency product listed until February 2023, introduced a 21.7% product that reaches a power output of 430 W. Like its predecessor, this product is also based on the shingled interconnection technology, stripping cells into 5 and a total of 61 cells are used to build this shingled module.
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. 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. Thus, the 2 products now share the 39th rank.
Kalyon PV, fairly young and Europe's only fully integrated wafer-to-module maker, has also earned the 41st rank for itself with its PERC module of 21.61% efficiency. The module consists of 144 cells based on the 158.75 mm wafer format. This bifacial module has a rated power output of 380 W.
Of the remaining 16 PERC products, 4 reach 21.6% efficiency. 3 products from this group – from GCL-Si, Talesun and Trina Solar – have the same power rating of 670 W owing to the same cell count of 132 half-cells of the G12 size. JA Solar's DeepBlue 3.0, built with M10-sized 156 half-cells, has a lower power rating of 605 W. While listed lower, it is ranked the same at 42nd.
The next 7 products, with an efficiency of 21.57%, share the 46th 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 count of half-cell strips.
EGing PV's PERC product is the lone beholder of the 53rd rank that it slipped to from the 51st place in April, with an 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 4 products at rank 54, again lower by 2 compared to last month. These products are offered by Runergy, Qcells, Astronergy and CECEP, all sharing this position.
Summary
