Solar Power

The SDDirect Module technology is recognized as a stable, established product and represents 90% of the worldwide market. The manufacturer guarantees an optimum performance of up to 80% over a 25 year period with the panels boasting a life time of over 30 years. SDDirect Poly-crystalline and Mono-crystalline technology modules 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.
