Technical FAQs 4

Can plug-in solar be legalized in Europe?

The EU and national governments are increasingly recognising the possibilities of plug-in solar, with new policies emerging to match market realities. Belgium is expected to legalise plug-in solar in April 2025, while Germany has taken major steps to simplify grid registration for plug-in solar.

What is a plug-in solar PV system?

The solution consists of usually one or two solar PV modules, which can be plugged into a grounded home power socket. A common type of plug-in solar PV is ‘balcony solar.’ In some markets in Europe, plug-in PV can cover up to 25% of annual household electricity needs.

How many plug-in PV systems are there in Europe?

The plug-in PV market is growing in Europe, though exact numbers are difficult to uncover. Germany leads the way with over 780,000 registered plug-in PV systems by the end of 2024. Estimates suggesting up to 4 million systems could be in use in Germany, many of which remain unregistered.

What is Solarpower Europe?

Same permitting rules as for standard PV. SolarPower Europe, the premier association for the European solar PV sector, unites 320+ organisations. Collaborating with members, we shape regulations and business landscapes for solar’s growth. Our dedicated policy experts lead focused workstreams, addressing key issues and influencing legislation.
