As an investor respectively operator of a PV plant you should have received the end-of-year results from your energy supplier or network operator. Often this is a disillusioning moment since the original rating has not been achieved, hence yields are not as expected.

Avoid a further loss of performance by having your PV system checked by the ADLER Solar Repowering experts!
We conduct a detailed status quo analysis of the PV plant, develop a tailored planning concept plus list of recommended measures and profitability assessment before we offer a technical turnaround concept. The project management includes recycling of old modules as well as handling of warranty claims. We also take over negotiations with the network operator for you.

Profit from our long-standing know how as a full service provider and effective project control from a single source. The result is a significant yield increase of your PV system.
