Find Out If UK Plug-in Solar Will Save You Money
Calculate your likely annual savings in under a minute, then see which legal plug-in solar kit gives you the fastest payback.
Traditional solar isn't right for everyone
Many people want lower electricity bills but can't justify a £7,000-£14,000 rooftop solar installation.
If you rent, live in a flat, or simply want a lower-cost option, plug-in solar may now be worth considering.
The difficult part is knowing whether it will actually save you money.
Balcony Solar Kits in the UK
Balcony solar kits are the fastest way to start generating your own electricity in the UK without scaffolding, drilling, or a long wait for an installer. A typical balcony setup uses one or two rigid 400–465 W panels on a secure balcony bracket or ground frame, wired to a plug-in microinverter or an all-in-one unit like the EcoFlow Stream.
From 27 August 2026, plug-in panel microgenerators up to 800 W will be legal in the UK under the new SI 2026/848 regulations. That means a compliant balcony solar kit can be plugged into a normal UK socket and run in parallel with the grid. Read the regulations summary.
The best balcony solar kits for UK renters and flat owners are modular: You can even start with a single panel and add more as your budget allows, and you can take the whole system when you move unless you have fixed to a roof.
