Your individual savings will depend on your circumstances. They’re influenced by factors like:

• The size of your home, which affects how much energy you use and how many panels can fit on your roof
• The appliances you use: things like heat pumps, hot tubs or electric vehicles affect energy usage a lot
• The angle and direction of your roof, which affects how much light you get throughout the year
• The energy tariffs you’re on, which affect the rate you pay for electricity

That’s why we always offer a free 30-minute consultation to customers before discussing any specific savings figures. We need to know about your circumstances to give you an accurate quote!

To give some idea though: 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.

Yes! This is one of the key benefits of going solar with a home solar battery – which we offer as standard.

You’ll need to sign up to an ‘export’ tariff, which lets you sell energy back to the grid. When you join Sunsave, we recommend the best export tariff for your situation and give you guidance on how to sign up.

Your export tariff doesn’t have to be from the same energy supplier you’re already with, but many suppliers do offer existing customers better rates.

Yes, definitely. We don’t offer solar panels without a battery, because we believe this is by far the best way to get the most value from your system. 

Adding a battery means you can:

• access the best flexible energy tariffs
• store any excess energy your panels generate which you don’t need, and sell it back to the grid to make even bigger savings
• charge up with cheap overnight electricity, which you then use during the day when buying energy from the grid would otherwise be more expensive
