Estimate how much electricity a solar PV system could make, how much you might use yourself, how a battery could change this, and the possible yearly saving.
Your Solar System
If you already have a solar quote, use the figures from it where possible.
The generation figure is editable because roof direction, shade, location and system design can all affect solar output.
Your Electricity Use
This is the share of solar electricity used in your home while it is being made, before battery storage is added.

Estimated Yearly Benefit
Battery-only simple payback: 71.4 years
Where Your Solar Electricity Goes
This calculator gives an estimate only. It is not a solar or battery quote and does not guarantee savings.
Actual results can change because of roof direction, shade, weather, panel performance, battery losses, battery ageing, electricity prices, export payments and when you use electricity.
For the best estimate, use generation and performance figures from a proper survey or installer quote.
