Storage Battery


If you have solar panels already installed and would like to further reduce your energy outgoings then a storage battery is perfect for you.

Adding To Your Investment

If you already have solar panels fitted and want to get even more out of your investment, then our solar battery only installation is the right choice for you.


A solar battery collects excess energy from the installed solar panels, and stores that energy to be used in your home when solar panels aren’t working during non-daylight hours.  Your battery can also automatically sell any excess energy it doesn’t use back to the national grid, saving you even more money all year round.

The question of how much a solar battery costs isn’t a one size fits all answer.  The cost will depend on the size of the battery your home needs, and how many solar panels you have fitted.

By adding a solar panel and battery system to your home you will save much more money on your energy bills as you won’t need to use as much energy from the national grid, allowing you to enjoy the full benefits of harnessing solar energy.
