Powerful panels up to 375Wp, featuring multi-busbar technology and 120 halfcut monocrystalline cells


Our latest solar panel series features 166mm large-size silicon wafers and monocrystalline PERC cells. The new panels come with the same innovative design features introduced with the MHE series allowing high power output of more than 200Wp/m2. Based on superior multi-busbar technology, the MHI series integrates advanced halfcut cells and non-destructive cutting.

The MHI series now comes with a 12 year product warranty and insured 25 year power output guarantee to 83.1%, thanks to our experience in manufacturing halfcut and multi-busbar technology.


A combination of innovations

Multi-wire and halfcut technologies for superior reliability and performance
