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.

LONGi's crack-free intelligent welding technology increases the power

and efficiency of the module and improves the load resistance of the

module.

The working current of the optimized electrical parameters

component is about 13A, which is perfectly adapted to mainstream

string inverters.

The bifacial power generation superimposed on the

back of the module generates electricity, the comprehensive power

generation capacity is higher, and the power generation gain has been

verified by customers and third parties.

Reasonable module size M10

silicon wafer with double-glass framed design to ensure module load,

suitable for two-person handling of module weight, fully consider the

arm span during manual handling.
