Domestic Solar PV & Battery Storage
What is Solar PV & Battery Storage?
Solar PV (photovoltaic) panels convert sunlight into electricity for use in your home. In the UK, they produce electricity even on cloudy days, reducing your reliance on the grid. Battery storage lets you store excess solar energy to use later (when the sun isn’t shining), like in the evening. This helps lower your annual electricity bill, increase energy independence and reduce your ‘carbon footprint’.
Domestic Solar PV & Battery Storage Explained
Frequently Asked Questions:
1. How much does it cost?
There are several factors that influence the price of a Solar PV & Battery Storage system, for example; size of scaffolding required, number of batteries required, any enabling electrical works required, any enabling roof repairs or adjustments required, external secure equipment storage space required etc.
Small Terraced House ~ £10,000 - £15,000
Medium Semi-Detached House ~ £15,000 - £25,000
Large Detached House ~ £20,000+
2. What is the average payback period**?
The time it takes to pay-off the initial cost of your Solar & Battery Storage System varies depending on several factors, for example; the amount of electricity your home consumes per year, the tariffs available from your electricity supplier (do they offer a day/night tariff?), the initial cost of the system itself, the ratio of enabling works to energy generating & storage equipment (does your roof or house electrical infrastructure need substantial upgrades to allow the Solar PV & Battery Storage to be connected?) etc.
Best Case ~ <6 years
Average ~ 7-10 years
Worst Case ~ 11 years+

**Be very wary of inflated payback periods marketed by installers / designers where assumptions of electricity price increases have been factored in. There is no guarantee the price of electricity will increase every year, in fact, it may even decrease!
