We don't recommend a kit until we can confirm its listing. Check the register before you buy.

Not electrical advice. We compare products; we are not electricians. Before you connect a solar kit to your home, ask a qualified electrician to check the socket, the circuit and your consumer unit, and follow the maker's instructions.

Note: We could not confirm a separate register entry for the roof-bracket versions. Check the ENA register before you buy. Working at height on a roof is a job for a professional.

Why it's worth a look

  • Could take about £113 a year off your bill (south-tilted, someone home in the day): payback in about 5 years at today's prices.
  • No roof work and no installer for the kit itself; take it with you when you move.

Watch out for

  • Sold out at every seller we checked.
  • Not yet confirmed on the ENA Type Test Register. Only connect a register-listed kit.
  • Output is capped at 800 W by the rules, so panel watts above that add less than you might expect.
  • You must tell your network operator () after plugging it in.

Reliability signals

  • Repairs: through the maker's UK support; we list known issues only from named reviews, and none are recorded yet
