Description

It features Poly-crystalline and Mono-crystalline technology modules which are the most efficient modules in the world (best Wp/sqm ratio). High yield modules (minimum of 130 Wp/sqm) guarantee an optimized space occupation (2 ha for a 1 MWp project) unlike other photovoltaic technologies such as Thin Film modules which have a lower yield (up to 3,5 ha for a 1 MWp project) and are compounded of heavy metals.
