STC: radiation 1000W/ square meters, component temperature 25 C, AM=1.5



Durable PV modules, independently tested for harsh environmental conditions such as exposure to salt 


mist, ammonia and known PID risk factors.

Advanced Glass

Our high-transmission glass features a unique anti-reflective coating that directs more light on the solar 


cells, resulting in a higher energy yield.

Extended Size


Our large-format module facilitates system-level cost savings through reduced handling and installation
