Why Solar Battery Storage?
Whilst solar panels drastically reduce your power bills, they do have some limitations. Firstly any excess energy generated by your system is sent back to the grid at a fraction of the price you will later buy it back for. Secondly, when the sun goes down, your energy generation ceases for the day. Finally, in the case of a power outage, batteries ensure power continues to run through your house.
Batteries maximise the benefits of your solar system and provide greater independence from power outages and rising electricity prices.
