In this article, we explain some of the advantages and disadvantages of home battery systems, provide a battery cost guide, present some alternative options to using batteries, and present a detail.
How much does a storage battery cost?
Capacity is the main factor that dictates how much a storage battery costs. It works out at around £900-£1,000 per kWh of electricity a battery can store. The more solar panels you have, and the higher your energy usage, the larger your battery's capacity will need to be.
Alternatively, you could install a home storage battery. These store your electricity to use later, making your energy system more independent from the National Grid. Usually battery storage is used alongside solar panels, but it can also be used with an energy tariff that offers cheaper electricity at off-peak times.
A solar storage battery is well worth having in the UK. If you add a battery to your solar panel system, you can use much more of the electricity your panels produce. This is because a battery stores any excess energy your solar panels produce when the sun shines, so you can use it to power your home after dark.
But while a battery can save you a fortune in electric bills, it is a chunky upfront investment. The average price of a storage battery for a UK home is £5,000. Prices vary according to factors including a battery's capacity, lifespan and brand name. You can also cut the cost of solar panels and a battery by having them installed at the same time.
A solar battery system helps to protect you from energy price rises, since it means nearly all your electricity will come from solar. A three-bedroom property with a solar panel system and a 5kWh battery will save nearly £600 per year through reduced electricity bills.
The benefits of adopting battery energy storage systems extend beyond mere cost savings. For instance, these systems can significantly enhance energy security and resilience for households. By storing energy, homeowners can maintain a supply during power outages, ensuring that essential appliances and systems remain operational.
