What is it?
What is balcony solar?
Balcony solar panels — also known as balcony power stations or Stecker-Solar (plug-in solar) — are compact photovoltaic systems designed to be mounted on a balcony railing, flat roof edge, or garden fence. They require no rewiring or professional electrician.
Here’s how they work: sunlight hits the solar panels, which feed electricity to a micro-inverter that converts DC power to the 230V AC your home uses. You plug the system into a standard 13-amp socket, and from that moment your home draws less electricity from the grid — reducing your bill automatically.
A typical UK system runs at 300–800W, costs between £400 and £950, and can save a household £80–£200 per year depending on usage, orientation and local irradiance.

Popular in Germany, growing in the UK. Germany now has over 1.2 million balcony solar installations. The UK is catching up fast — particularly since the government’s 2026 legalisation announcement.

Renting? You’re not forgotten.
There are an estimated 4.4 million private rented households in England alone. For too long, access to solar energy has been restricted to homeowners. Balcony solar changes that.
Because these systems plug in rather than connect to your wiring, many renters can install them without landlord permission — though we always recommend having an honest conversation with your landlord first. Our renter’s hub covers everything from legal rights to a ready-made letter template you can send today.
