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: EcoFlow claims savings of "up to £115" a year. Warranty length is not stated on the kit page. Register entry seen for the 800 W facade kit; check the entry for the size you buy.
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 4 years at today's prices.
- Confirmed on the ENA Type Test Register, so it can be plugged in under the UK rules.
- 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.
- 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
