Your independent expert on site in the capital region
Looking for a PV expert in Berlin or Brandenburg? As a Berlin-based, TÜV-certified photovoltaic surveyor, I assess your system independently, manufacturer-neutral and free of conflicts of interest – on site across the entire capital region. Short travel distances mean fast appointments and low travel costs.
The region has its peculiarities: dense urban development with shading from neighbouring buildings in Berlin, ground-mounted and rooftop systems in the Brandenburg surroundings, and the requirements of local grid operators and insurers. I know this practice from numerous on-site visits.
