module power output and operational efficiency.

Renowned globally for exceptional power generation in multi-faceted modules.

Unmatched quality assurance for zu'jian components

Smart welding technology eradicates hidden cracks. Our innovative welding

technique enhances module power output, efficiency, and

boosts module load resistance.
 

 

Augmented module power

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

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

over the module's extended lifespan.

Optimized BOS and LCOE costs

System BOS costs slashed by 5.7%, and a 3.5% reduction in levelized cost

of electricity (LCOE). Seamlessly integrates with mainstream market

tracking brackets.

Enhanced operational reliability

LeTID minimized by 50%, significantly reducing hot spot risk and power loss

due to shading.
