Product Feature and Application

Stable and Reliable

Exceptional PID resistance ensures stable power generation even in harsh environments.

High Power Output

Low temperature coefficient (-0.29%/°C) minimizes power loss during hot weather, maximizing overall energy generation. Strong low-light performance also boosts output during early mornings, evenings, and overcast conditions.

Robust Warranty

We offer a 15-year product manufacturing warranty, extendable to 25 or 30 years. Coupled with a 30-year linear power output guarantee, it delivers peace of mind for years to come.
