Millions of people want lower bills and cleaner power. Many are now looking at rooftop solar. The idea is simple. Make your own electricity. Use more at home. Buy less from the grid. And cut emissions while you save.
Why now?
Energy prices eased this summer. But they’re still high by past standards. From 1 July to 30 September 2025, the price cap for a typical home is £1,720 a year. That’s down 7% from spring, yet about 10% higher than last summer.
So households are chasing long-term fixes. Solar helps because it offsets grid use. It also lets homes get paid for extra power they export under the Smart Export Guarantee (SEG).

What solar can do for a home
The Energy Saving Trust says solar cuts electricity bought from suppliers. It also cuts carbon. A typical home system can save around one tonne of CO₂ a year, depending on location. That’s a clear climate win.
System size varies. Many UK homes install systems near 3.5 kWp. That size usually needs about six to twelve panels and 10–20 m² of roof.
- Lower bills: Use free sunlight to power appliances and charge batteries.
Lower carbon: Replace grid electricity with clean generation.
Export income: Get paid for surplus electricity under SEG.
