Start with your postcode
Sunlight varies more than you'd think across the UK. We'll use the actual figures for your area.
That doesn't look like a UK postcode. Have another go.
No email needed to see your first result.
Annual sunlight, by region
kWh generated per kWp installed, per year. It's a smaller gap than most people expect - Glasgow still gets 80% of what Truro does.
01
You stop buying electricity you're making yourself
Every unit your panels make and you use is a unit you don’t buy at 26p. This is where most of the saving comes from – not from selling it.
02
You sell what you don't use
Whatever you don’t use goes back to the grid and your supplier pays you for it. It isn’t a fortune. It adds up quietly in the background.
03
A battery moves the saving to when you need it
Usually the difference between using about a third of what you make and around three quarters. Is a battery worth it?
Panels make most of their power at lunchtime. Most homes use most of theirs around 6pm. Nearly everything else follows from that.
The simple version
Three ways it puts money back
- You will never use 100% of what your panels produce.
Anyone showing you a saving based on that number is either being careless or hoping you don’t check. Without a battery, most homes use around a third of what they generate.
- A north-facing roof genuinely might not be worth doing.
We’ll tell you if your roof isn’t right for it. We’ve talked people out of solar before and we’ll do it again.
- Payback is usually 8 to 12 years, not four.
Anyone promising you four is quoting a best case they can’t guarantee. Panels also lose about half a percent of their output every year, and that belongs in the maths.
