Instead of sending excess energy back to the grid, keep it under your roof
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.
