Most plug-in solar ads exaggerate. We’d rather you know the real numbers. The government’s own estimate for plug-in solar is £70–£110 a year – in a sunny spot the Duo does a little better.

*Savings estimate: south-facing, unshaded, approx. 650 kWh/year, 60–70% used at home, electricity at 26.32p/kWh (Ofgem price cap, 1 Oct–31 Dec 2026). Results depend on location, orientation, shading and usage.

Questions, answered

Is plug-in solar legal in the UK?

Yes, in England, Scotland and Wales since 27 August 2026, for kits listed as compliant on the ENA register. The Solarfy Duo 910 is listed as SOLAW/21608. One kit per household, up to 800 W. Not yet permitted in Northern Ireland.

Do I need an electrician?

Not for most homes. You plug it into a suitable fixed wall socket. You’ll need an electrician if you need a new outdoor socket, or if your wiring is old and has no RCD protection.

Can I use an extension lead or adaptor?

No. The kit must plug directly into a fixed wall socket. That’s why we offer 5 m and 10 m solar DC cables instead.

How much will I really save?

Around £100–£120 a year in a sunny, unshaded spot at today’s price cap, if you use 60–70% of the power at home (about 650 kWh a year). The government’s estimate for plug-in solar is £70–£110 a year. Shade, direction and when you use electricity make the difference.

Does it work in winter or when it’s cloudy?

It still makes power in daylight, but much less. Most of the yearly output comes from March to September – setting up now means you’re ready for spring.

I rent – can I use it?

Yes, with your landlord’s or freeholder’s permission – we include a letter template. It’s not allowed on timber balconies or combustible cladding. When you move, unplug it and take it with you.
