LESSO Solar showcased 210N and 210R solar cells with mass-production efficiencies exceeding 26%
The company highlighted high-density BC modules and quarter-cut TOPCon modules reaching up to 665 W and 24.62% module efficiency
The portfolio also includes an 800 W TOPCon module and an integrated residential solar energy system
Chinese solar manufacturer LESSO Solar showcased its latest solar cell and module portfolio at SNEC 2026. The company highlighted its 210N and 210R solar cells, along with its module portfolio based on quarter-cut cells, and back-contact (BC) and TOPCon technology.
According to the company, the 210N and 210R cell platforms achieve mass-production efficiencies exceeding 26%, with bifaciality above 80%, a temperature coefficient of -0.30%/K, 97% relative efficiency at 200 W/m², zero light-induced degradation (LID), and high PID resistance. The company further stated that its 210R quarter-cut and 210N passivated half-cut cells reach efficiencies of 26.3%, with the former reducing current loss for high-efficiency module packaging and the latter using edge passivation to improve reliability and reduce packaging losses.
LESSO Solar also highlighted its high-density BC modules. The company says that the busbar-free rear and grid-free front architecture of these modules maximizes light absorption, delivering 30-40 W higher power than mainstream TOPCon modules while improving low-light and high-temperature performance. At its booth, the company showcased a 210R BC module delivering 665 W with a module efficiency of 24.62%.
The company also exhibited a TOPCon module rated at 800 W and 23.65% efficiency. According to the company, the module uses proprietary cell technology and high-density packaging to achieve this high power rating, while also reducing balance-of-system (BOS) costs and the levelized cost of electricity (LCOE). It is based on the 210 mm platform with dual-glass configuration, and measures 2,596 × 1,303 × 33 mm.
The company also offers a 210 mm n-type TOPCon dual-glass bifacial module. According to its current datasheet, this TOPCon module offers up to 730 W of power with a maximum efficiency of 23.50%. Built with 132 half-cut cells, the module measures 2,384 × 1,303 × 33 mm and carries a 12-year product warranty and a 30-year linear power output warranty.
LESSO Solar also showcased a 210R TOPCon quarter-cut module with 665 W and 24.62% efficiency. The company claims its quarter-cut architecture delivers up to 30 W more power than conventional half-cut designs while improving crack resistance and reducing the risk of hotspots. The showcased module measures 2,382 × 1,134 × 30 mm. LESSO Solar also offers a 210R n-type TOPCon dual-glass bifacial module with the same dimensions, offering 615-635 W with a maximum efficiency of 23.51%. Built with 132 half-cut cells, this module is backed by a 12-year product warranty and a 30-year linear power output warranty.
Also part of the company’s showcase was its integrated residential solar energy system, featuring 10 kW split-phase and 12 kW 3-phase solutions. They integrate DC/AC conversion, battery storage management, and smart monitoring while supporting both on-grid and off-grid operation.
