Solar Battery Installation in Dorking, Surrey
If you have solar in Dorking but still buy most of your evening electricity from the grid, battery storage may be the next step. Solar Panel Price can pass your enquiry to up to four battery installers working in and around Dorking, each able to survey the property and give you a written quote.
How a Solar Battery Works
During the day, surplus solar that the house is not using charges the battery instead of flowing out to the grid. Once generation drops, the battery supplies the house before any power is drawn from the grid. On a time-of-use tariff, it can also top up overnight at a lower rate, helping it earn its keep in winter when solar output is low.
Retrofit or New System?
Plenty of batteries are added to panels that have been on the roof for a decade or more. An AC-coupled battery can sit beside the existing inverter, but if the old inverter is ageing, a hybrid swap can deal with both jobs at once.
What Battery Installers Will Need to Know
- A photo of the inverter's rating label
- The size of your solar array in kW
- A recent bill showing kWh used
- Where you would like the battery to go
- If emergency power is a priority
- Any plans for an electric car or heat pump
How Much Is a Battery in Dorking?
Most home battery installations in Dorking cost between £3,000 and £8,500, with capacity and the inverter arrangement making the biggest difference. A 5kWh AC-coupled retrofit sits at the lower end, and large batteries with a new hybrid inverter or backup are at the top. Domestic batteries currently benefit from 0% VAT.
