Overview

• Economics Senator Franziska Giffey said the city will prioritize installing photovoltaics on large commercial and other owners’ roofs to tap underused potential.
• Berlin reports about 53,000 solar installations totaling roughly 459–460 MWp, supplying an estimated 5.6% of in-city electricity generation.
• The Masterplan Solarcity sets a target of at least a 25% solar share and around 4,400 MWp of installed capacity by 2035.
• Fraunhofer ISE and the city’s economic administration judge the 25% goal feasible but emphasize the need for a substantial acceleration in deployments.
• Recent growth has leaned on small balcony systems, with about 27,000 SolarPlus grants since 2022 including 19,000 for such units, yet officials stress larger systems deliver far more capacity.
