On average, you could save 94% on your electricity bills with a solar & battery system.
This is based on projected first-year savings from a sample of over 600 systems installed by Sunsave across the UK in 2025. The average system is 5kWp, with 44% of solar electricity used at home and 56% exported to the grid. Actual savings with solar will vary depending on several factors, including your property and system.
Why go solar?
With a solar and battery system, you’ll be buying less electricity from the grid and you’ll be able to sell any excess electricity to the grid. Combining these savings, your annual electricity bills can fall by 94%*, on average.
It could also increase the value of your property by up to £11,157**.
