What is a Solar Battery?
A solar battery, also sometimes referred to as a ‘home battery’, is a device which stores electricity for later use. Usually this is electricity generated from the sun, making it a perfect addition to your solar panels. However, solar batteries can also store electricity from the grid if need be.
You can use this stored energy to power your home when your solar panels don’t generate enough electricity, such as at night or during extreme weather conditions. Some solar battery storage systems even work during power outages, so you can continue to use your home appliances without any disruptions. Meaning you could potentially be 100% independent from the grid.
Furthermore, for those of you who want to make some extra money, in the UK it’s possible to sell your solar battery’s stored surplus energy back to the grid through the Smart Export Guarantee (SEG). Alongside free solar energy generated from your solar panels, solar batteries can also help you save money through the grid by charging your battery during cheaper off-peak hours.
According to Powervault, you can reduce your energy bills by up to 50% through storing your solar energy during the day and then using it in the evening. And you can potentially reduce them by a further 15% if you only purchase electricity from the grid through cheaper night tariffs like Economy 7.
