The vast majority of people who have home battery storage—big batteries that can store lots of energy, to power a home—have them installed alongside solar panels. That’s because they make solar panel systems far more efficient, as surplus energy can be stored rather than going to waste.
That being said, home battery storage in the UK without solar panels can still offer cost savings by storing cheaper, off-peak grid electricity for use during peak hours. This is beneficial for leveraging lower energy prices (and providing backup power should you need it). However, the initial cost can be high, and without solar, the environmental and financial benefits are less. It’s a practical option for those focused on energy independence and managing electricity costs, but the return on investment and sustainability benefits are more limited compared to combining it with solar generation.
