Savings depend on your electricity tariff, how much of your generation you use directly, and whether you have battery storage. We model this for every quote.
Typical savings
- Small 3 kWp system, no battery: around £300–£450/year.
- 4 kWp system, no battery: around £450–£700/year.
- 5 kWp system with battery: around £800–£1,100/year.
Two ways solar saves you money
Direct use: every kWh you generate and use is a kWh you don't buy from the grid. Export payments (SEG): your energy supplier pays you for every kWh you export.
Payback
Most systems now pay back in 7–10 years and continue to save for another 15–20 years after that.
