Increased module power

Featuring 210 mm wafers, 132/120 half-cut cells, and PERC cell technology

Module power reaches up to 670W with a 0.4% increase in power generation

over the module's lifespan.

Reduced BOS and LCOE costs

System BOS cost reduction by 5.7%, and 3.5% decrease in levelized cost

of electricity (LCOE). Perfect compatibility with mainstream market

tracking brackets.

Enhanced reliability

LeTID reduced by 50%, low hot spot risk, efficiently minimizes power loss

due to shading.
