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. The GivEnergy 9.5kWh 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 Diss Is Ideal for Battery Storage
Diss and the Waveney Valley receive 1,030+ kWh/m² irradiance. The border area between Norfolk and Suffolk has gently rolling terrain with open agricultural skylines. Diss Mere's lakeside setting provides a unique microclimate. Higher solar generation means more surplus electricity available to store — making battery storage in Diss particularly cost-effective compared to areas with lower irradiance.
