“Which roofs are suitable for photovoltaic installations? How much electricity could such facility produce? What would the investment cost be?
The Solar Atlas Berlin shows the city’s solar potential down to the individual building. Property owners and investors can use the Atlas to determine whether a building’s roof is suitable for a solar installation and whether the investment will pay off. The Atlas provides key information at a glance on such matters as the potential power output, reductions in CO2 emissions, and investment costs.”

Using the Berlin Solar Atlas

A 2D web application with no plug-ins required allows you to start the Solar Atlas in your browser directly. Simply enter any address and click on a building to obtain information about its solar potential.

Experience the Berlin Solar Atlas in three dimensions using Google Earth! To access the Solar Atlas in Google Earth, you must install Google Earth and download a launch application. To try it, follow the installation instructions to the right. Download the launch file (kmz) for the 3D city model in Google Earth with the integrated Solar Atlas. (free download)

About the project
By creating the Solar Atlas Berlin, the city has shown its clear commitment to investing into the future of renewable energy, while also underscoring the capital’s role as a center of innovative green technologies.

About 500,000 roofs in the capital were surveyed for the Solar Atlas using laser systems in airplanes. Data on such matters as the roofs’ slope, compass orientation, and amount of shadow vs. sunlight received by each roof were used in calculating each building’s solar potential. The amount of solar radiation received and the average price and efficiency of solar cells were also part of the evaluation. The Solar Atlas uses the 3D model created by the Land of Berlin, which is based on official cadastral information.

The atlas provides detailed information about more than 30 photovoltaic installations, solar-thermal systems and buildings with other solar energy concepts. It also presents 30 relevant producers, associations and research institutions of the solar industry.

There are three ways to access the Solar Atlas: a 2D web application with no plug-ins required, an internal 3D model and a public version in Google Earth.

The Solar Atlas was realized in cooperation with the Berlin Senate, virtualcitySystems GmbH and the engineering firm simuPLAN.
