SonneSammeln on a grand scale - a Profit for all
Solar parks are booming. The reasons for this are obvious: solar energy is the cheapest form of electricity generation today, it is widely accepted and particularly environmentally friendly. Photovoltaics is the decisive solution for converting our energy supply to be climate-neutral.
Good prospects for local authorities, landowners and local people to take their future into their own hands.
New PV knowledge area

In co-operation with the Open Energy Trackerwe show you the current expansion figures for ground-mounted PV in Germany. While the figure on the left illustrates the current stock and trend of ground-mounted photovoltaics (FFPV) and sets it in relation to the current government targets, the figure on the right shows the continuous and accelerating expansion of PV in Germany. The data is taken directly from the Open Energy Tracker market master data register on a monthly basis.
