Solar Battery Savings Calculator
Thinking about adding a solar battery? Use our free calculator to estimate the right size, the extra you could save each year, and a rough cost. Figures are indicative — your exact numbers depend on your usage, tariff and whether you already have solar. We’ll always give you an honest answer.
Is a solar battery worth it?
A battery stores energy — either surplus from your solar panels, or cheap off-peak electricity — so you can use it during expensive peak hours instead of buying from the grid. That cuts your bills and shields you from price rises, and it keeps essential circuits running during a power cut. Payback is longer than for solar panels alone, but for many homes the combination of savings, backup and rising energy prices makes it worthwhile. We’ll always tell you honestly whether it stacks up for you.
