Photovoltaic solar panels create electricity at the time it is generated – in the middle of the day, which is often when we are not in the house or requiring much electricity. By installing a solar battery system, we are able to save the generated energy and store it for when we need it, or even sell it back to the grid!
In this way we can improve the above illustration in useable output by 40% adding to the savings!
This illustration is the cost of the solar panel system with the simple addition of a battery
- It can create 3946 kWh/year
- This would save you an average of £1342 per year and calculated at 0.34p/kWh as of 30/1/2023
- Total cost of the solar panel and battery installation is £10,600 with 0% VAT
The above cost example is based on using 405 watt solar panels measuring 1722x1134mm, a 8.6kW battery, standard on-roof fixings, relevant solar inverter, standard cabling, excludes scaffolding and assumes 100% usage.
