Add a battery to your solar system

How does solar battery storage work?

Adding a battery to your solar system allows you to store the excess electricity you generate during the day to power your home at night. This means you’ll import less electricity from the grid, saving you money on your energy bills. 

What is a solar battery?

Put simply, a solar battery allows you to store electricity generated from the sun via your solar panels to use at a later date. With a battery, you could use 30% more of the electricity you generate than with solar panels alone1.

Most typical solar systems would require a mid-sized battery of around 4-6 kWh. As a rough guide, a typical home suitable for solar consumes around 12kWh a day on average.

Frequently asked questions about solar battery storage

Where will the battery be installed?

We will conduct a full survey of your home that will help you to decide on the best location for your battery. It has to be fairly close to your main consumer unit so we have to take that in to account but we normally try to put it in a cupboard, garage, utility room or somewhere similar.

Can I have the battery in a loft?

No, our batteries can’t go in a loft space as they are too heavy. 

How big is the battery?

Our  batteries are around 0.4m wide, o.6m high and 0.2m deep

Can solar panels work without battery storage?

Yes you don't need to have a battery with your solar panels, however a battery storage system allows you to use more of the energy you generate in your home rather than exporting it back to the grid.
