Commercial Solar PV & Battery Storage

Commercial 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!
