Battery Storage in March

Battery storage lets you capture the solar electricity your panels generate during the day and use it in the evening, overnight, and on cloudy days — reducing your grid electricity use by 70–90%. In March, where average electricity bills run at £79/month, battery storage is one of the most impactful upgrades you can make.

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 March Is Ideal for Battery Storage

March sits in the heart of the Cambridgeshire Fens — one of the driest and flattest regions in England. The unobstructed horizon in all directions maximises solar exposure throughout the day. Higher solar generation means more surplus electricity available to store — making battery storage in March particularly cost-effective compared to areas with lower irradiance.

Complete Home Energy System in March

Battery storage works best as part of a complete home energy system. Pair it with solar panels to capture free electricity, a heat pump to eliminate gas or oil heating, and an EV charger to drive on sunshine. In March, the combined system typically reduces total energy costs by 60-80% and cuts household carbon emissions by over 4 tonnes per year.
