Solar Systems 2021

Statistical Base

As mentioned earlier, the previous method of data recording used in the solar cadastre was discontinued with the introduction of the Energy Atlas. The method switched to a combination of multiple sources and ways of presenting analysis results. In the future, this responsibility will be transferred to the Energiedatenbank (Energy Database), which currently forms the basis for the Energy Atlas.

The individual data sources are listed below:

Photovoltaics:

  • Energieatlas Berlin (Energy Atlas), Senate Department for Economics, Energy and Public Enterprises (SenWEB), online version as of March 2021
  • PV locations: data provided by the Bundesnetzagentur (Federal Network Agency) according to the Anlagenregisterverordnung (Installation Register Ordinance) and the core energy market data register (MaStR), as of January, 14, 2021
  • PV electricity feed-in: data provided by Stromnetz Berlin GmbH, as of December 31, 2016
  • PV coverage rate: data provided by the Bundesnetzagentur (Federal Network Agency) according to the Anlagenregisterverordnung (Installation Register Ordinance) and the core energy market data register (MaStR), as of January 14, 2021
  • PV potential: analyses of the Solaratlas Berlin (Solar Atlas), SenWEB, as of December 31, 2013
  • Postal code areas: data as of March 3, 2016

Solar thermal energy:

  • Energieatlas Berlin (Energy Atlas), Senate Department for Economics, Energy and Public Enterprises (SenWEB), online version as of May 2021
  • ST locations: data provided by the solar cadastre Berlin, as of December 31, 2015
  • Number of systems per borough or postal code: location data from December 31, 2015; supplemented by data from the Federal Office for Economic Affairs and Export Control for the years from 2016 to 2019, as of December 31, 2019
  • ST potential: analyses of the Solaratlas Berlin (Solar Atlas), SenWEB, as of December 31, 2013
  • Postal code areas: data as of March 3, 2016

It may safely be assumed that not all solar systems installed in Berlin are known, also in relation to the respective year of recording. For example, photovoltaic systems that do not feed into the grid and use the electricity exclusively for self-supply are not included in the data collection and the presentations. This applies both to off-grid systems as well as stand-alone power systems, such as PV modules on parking meters, park lighting systems and in allotment gardens.
