Future through solar energy

A partner for everything to do with solar energy.

That’s hep. Since 2008. We develop, build, operate and finance solar parks. World-wide. For energy production that can do more than supply electricity. The large-scale photovoltaic facilities we have developed have a capacity of around 1,310 MW peak. From our sites in Germany, Japan and the USA we operate 18 solar projects ourselves. Our active pipeline for future projects comprises around 5,300 MW peak (as at 12/31/21).
