Homeowners could save up to £796 per year on their energy bills by installing a battery storage system in their home, according to The Energy Savings Trust.
For a three-bedroom home, with average energy prices, this could equate to as much as 85 per cent of their energy costs.
While solar panels alone can save the typical household some £310 each year, battery storage systems enable energy transferred from sunlight to be stored for use at night.
Using solar panels alone will save homeowners around 30 per cent of their energy bill, according to Mark Millar, chief executive of battery maker Puredrive Energy.
He said: ‘The average home [with solar panels] consumes 10 kilowatt hours of energy per day, except only 30 per cent of the energy gets absorbed into the home because we generate in the day but use energy in the evenings and mornings.
‘The other 70 per cent of the energy goes to the grid, So the homeowner doesn’t see a benefit to that.’
According to Millar, adding a battery system allows this otherwise wasted energy to be stored and used in the evening and potentially the next morning, increasing savings to 60 per cent.
While some 1.4million UK households have solar panels, around 4.9 per cent of the population, just 43 per cent of those with solar panels, or 602,000, also have a home battery.
The most up-to-date systems, however, can make the most of variable tariffs to store energy when it is cheap, for use during periods where it is more expensive.
