Buy energy when it's cheap. Use it when it isn't.
A home battery stores your solar generation and off-peak grid power, then runs the house through the expensive hours. It's the single biggest upgrade to a solar system's returns.
Why it pays
The gap between buying and selling is the whole point
Export earns you maybe 4–15p per kWh. Buying back at peak can cost 30p or more. A battery keeps that difference in your pocket.
Time-of-use arbitrage
Charge overnight at around 7p, avoid daytime rates three to four times higher.
Higher self-consumption
Solar homes typically jump from around 40% to 80% self-consumption.
Optional backup
Specify backup wiring and keep essential circuits alive through a power cut.
