Methodology of the PV-list creation

To compile our photovoltaic list, our research team conducted a detailed analysis of the German solar industry. For this purpose, the top rated and most relevant PV installers were identified in each major German city. The entries were primarily based on the number of installed systems and customer ratings. In addition, installers of ground-mounted systems and solar parks were identified with particular focus. These were also immediately classified as “top installers”. In addition to major cities, regional areas were also searched for the leading installers.

Since numerous installers also have websites that appear to be outdated at first glance, our team additionally called such entries and inquired about their current business activities.

Note: Despite our intensive research and detailed analysis, it is always possible that additional PV installers would have to be included based on installed capacity. For this reason, we are constantly updating the list and look forward to your input at kontakt [at]
