Store surplus electricity generated by your PV system with solar battery storage – for even more energy independence
Solar battery storage has been around for a few years, and now – with smart tariffs – it enables you to save money in at least three different ways. For example:
1. Capture excess solar electricity
Most solar PV systems generate more electricity than the house can use. This excess electricity will flow out to the national grid and be lost. However, with solar battery storage, some of this surplus solar electricity is captured in one or a series of batteries and less energy flows out to the grid. This stored electricity will then automatically discharge to the house when you need it, perhaps when you’re preparing dinner, for example.
2. Charge your battery at cheap, off-peak rates
Even if you don’t have solar panels, home or business battery storage can bring benefits. Modern smart tariffs, and even old Economy 7, charge you at different rates for the electricity you use at different times of the day. For example, you might pay 7.5p per unit at night and 30p during the day. Home battery storage allows you to fill your battery with cheap electricity off-peak, and then let it out when you need it during the day when rates are higher. In this way, battery storage can lower your daily electricity bill.
3. Let your battery charge your electric car
When you join the electric car revolution, you’ll find the combination of solar panels and home battery storage is very attractive. You can store excess solar electricity in a battery during the day, then use it to charge your electric vehicle when you get home from work and plug in. There’s nothing like filling your car with sunlight!
