Why Solar Batteries?
Power Your Home for Longer
Solar PV panels can create lots of energy, sometimes too much for a property to use at once.
And unfortunately, without a solar battery installed, any excess energy created by solar PV panels is sent back to the National Grid, rather than kept under your roof.
This means that while you may have had enough to survive the night comfortably, you’ll now be relying on your energy supplier to power your home.
However, with a solar battery, your home can use up any surplus energy sitting in the battery to power your home throughout the evening and night-time.

How much can I save from installing Solar Batteries?
Increase your savings by up to several hundred pounds a year!
Adding a solar battery to your solar panel system allows you to store the energy you generate during the day and use it when you need it most—like in the evenings or on cloudy days. This can reduce your reliance on the grid and help lower your energy bills even further.
According to the Energy Saving Trust, a typical home with a 4.2 kilowatt-peak solar panel system can save between £210 and £514 per year on their energy bills.¹ By adding a battery, you can increase the amount of solar energy you use, potentially boosting your savings beyond this—especially if you use most of your energy in the evenings when electricity from the grid is more expensive.
