Do solar panels work in the UK?

Real data from 1.85 million systems. Regional yield tables (800–1,132 kWh/kWp), seasonal output, and why "it's always cloudy" is a myth. 2025 was the sunniest year on record.

The UK regional solar installer landscape 2026

Why regional firms are winning the retrofit market — and a tour of who is serving where, region by region.

Choosing an installer

Before comparing battery brands it is worth working out what size solar battery you actually need. And churches bring their own rules — listed-fabric fixings and faculty jurisdiction — which is why parishes go to dedicated UK church solar specialists.

Funding is where most commercial projects stall, and Commercial Solar Grants maps what help genuinely exists. Car parks are the growth story in commercial PV this year — solar panel canopies cover the structures making it happen.

When you're ready for quotes, a good local installer usually beats a national call centre on price and aftercare — see, for example, solar installers in Hertfordshire, ElectriFusion Solutions in South Yorkshire, or AMP Pro Electrical. For EV-charger pairing, this Zappi vs Ohme vs Hypervolt comparison is a useful read. Running a business instead? See solar panels for UK factories and the commercial solar payback period. For batteries specifically, an installer's Sigenergy vs Tesla vs GivEnergy comparison is a useful real-world read.
