Smart Tariffs: Maximise Your Battery

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.

Octopus Agile — pay by the half-hour
Octopus Flux — sell and buy at same time

How Battery Storage Works

1

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.

2

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.

3

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.

4

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 Downham Market Is Ideal for Battery Storage

Downham Market sits on the Fenland edge where flat terrain meets the gentle slopes of West Norfolk. The Denver Sluice area has unobstructed horizons providing excellent solar exposure at 1,030+ kWh/m² irradiance. Higher solar generation means more surplus electricity available to store — making battery storage in Downham Market particularly cost-effective compared to areas with lower irradiance.
