The Money Saving Opportunity Millions of Homeowners are Missing Out On
Are you looking at ways to save money on your energy bills but don’t have the finances or a suitable roof for solar panels? At SolarTherm UK we have a solution to your home energy needs. Even without solar panels, you can still save money by installing a home battery storage system.
Home battery storage can reduce your energy bill by benefitting from off-peak tariffs. Your battery storage system can be programmed to charge from the grid during these off-peak lower rates, such as Economy 7 or Octopus Go.
Let’s look at some figures. Octopus Go off-peak rate is currently 8.5p per kWh (as of March 2025). The Voltsmile 10.24kWh battery, fully charged on the off-peak rate would cost you 87.04p, you would then use this energy during the day to reduce the amount of peak rate electricity you draw off the grid. Octopus Go peak rate is currently 28.96p per kWh meaning 10.24kWh of electricity from the grid would cost you £2.97. Using a home battery storage system could potentially save you up to £2.10 per day, or £766.35 per year.
A home battery storage system also allows you to have back up power in the case of a power cut. When installing your battery system, opt-in for an Emergency Power Supply (EPS) so your battery system can keep important rings on your circuit board powered in the event of a power cut. This can be especially useful if you have home medical equipment that requires electricity to continue running.
At SolarTherm UK, while we look at the benefits of a complete solar PV system from panels to batteries, we can’t argue with the figures that prove a battery installation on its own can reduce your energy bills and reduce your reliance on peak rate electricity imports.
