With a smart electricity tariff like Octopus Agile or Flux, your battery charges automatically on cheap overnight electricity (typically 2–8p/kWh), then discharges during expensive peak hours (25–35p/kWh). This can add £200–£400/year in additional savings on top of the solar benefit.
How Battery Storage Works
Solar panels generate electricity during daylight
Your home uses what it needs in real time. Surplus electricity that would otherwise be exported to the grid is sent to the battery.
Battery stores surplus solar electricity
Modern lithium batteries are 95%+ efficient, retaining almost all the energy they receive. A 9.6kWh battery stores enough for a typical evening's use.
Battery discharges in the evening and overnight
As solar generation drops after 4–5pm, the battery automatically discharges to power your home. The grid only tops up when the battery is depleted.
Smart charging from overnight cheap-rate electricity
On smart tariffs, the battery can also charge from the grid during cheap overnight hours (typically 12am–5am at 7–15p/kWh).
Why Bury St Edmunds Is Ideal for Battery Storage
The Bury St Edmunds area receives 1,030+ kWh/m² solar irradiance annually. West Suffolk's agricultural landscape and open skies mean excellent solar generation with minimal shading for both residential and commercial rooftops. Higher solar generation means more surplus electricity available to store — making battery storage in Bury St Edmunds particularly cost-effective compared to areas with lower irradiance.
Local Grant Support in Bury St Edmunds
