Household Solar Battery Storage Systems Can Make Sense or Not. Here’s Why.
You Export a Lot of Unused Solar
If you are exporting a lot of unused solar power during the day and using it all in the evening then a battery could be of value to you. Check your smart meter to see how much you are exporting during the day. If it is a lot then a battery would pay for itself quickly.
Your Evening Usage Is High
Batteries are very effective at saving money at peak times, i.e. when you use power in the evening when most people are returning home from work and doing their cooking and washing. So, if you have an electric car, use loads of power for cooking, have a big house that’s always full and use lots of power after dark, then a battery will save you a lot of money.
Your Tariff Makes the Maths Work
Battery charging can also make sense for households with Time-of-Use tariffs, where the rate paid for importing energy is lower during certain periods of the day (such as overnight). The battery is charged up during these cheaper periods, and used to meet peak tariff demand later in the day.
Grant Support Is Available
Even though prices have fallen dramatically in recent years for home battery storage systems (the cheapest are around £2,500 for a basic system and £6,000 for a more premium model) there are often grants available for their installation.

Payback Is Typically Seven to Twelve Years
The payback is between 7-12 years depending on the individual’s circumstances. If most of the points above are relevant to you then the payback is likely to be towards the lower end of this range. If only a few then it’s worth waiting a bit longer for the costs to fall or for your circumstances to change.
Check out the payback estimate for your specific circumstances. Make sure you enter your current bills to get a realistic payback period.
