Solar in Berlin

Berlin sits close to Germany's national average for sun — not the sunniest, not the cloudiest. It's also one of the slower-adopting big cities for Balkonkraftwerk relative to its size, which has nothing to do with the weather.

How to tell if today is worth it

The annual averages above set expectations, but any single day in Berlin is driven by cloud. The free Sun Hours app takes your postcode and your system’s best-ever day, then gives Sol’s personalised 7-day forecast — so you know whether to run the washing machine now or wait for tomorrow. Setup is two questions and there’s no account.

Thinking about a Balkonkraftwerk? Germany's Solarpaket I (May 2024) raised the plug-in limit to 800W and made registration far less bureaucratic — see the SolarDE guide for what's changed and what it means for Berlin.
