Store Cheap Off-Peak Power

As the vast majority of tariffs are time-of-use, i.e. they vary depending on the time of day, storing power at night when it’s cheap and using it during the day when it’s expensive in peak hours, makes absolute sense. For example, Octopus Go is currently charged at 7p per kWh overnight (midnight to 5am) and 25p+ per kWh in peak hours. By storing power overnight and using it during the day, you can save a huge amount of money on your electricity bill.

Avoid Evening Grid Surges

The evening peak hours of 4pm-8pm are the hours that your Solar Battery Storage will earn its keep most visibly. But also in these hours the energy price cap will be charged at the highest rate for imported energy. On average a UK household uses 2-3 kWh of energy in the evening hours. A battery of 5 kWh will easily cover this load.

Earn Smart Export Guarantee Payments

Even when your solar panels are generating more electricity than your battery can store, any excess electricity generated by your solar panels will be exported to the grid and you will receive a Smart Export Guarantee (SEG) payment for this. These payments are currently between 4p and 15p per unit of electricity exported.

Match the Battery to Your Usage

We don’t make batteries but we can recommend a good solar battery storage installation company for you. When choosing the right battery size for your home it is essential to check your smart meter data for your typical evening draw.

Pair Storage with a Time-of-Use Tariff

The savings will be real but limited without a time-of-use tariff. With a tariff, you can add the benefits of off-peak charging to the power that your solar panels are already generating. The more, the merrier!

The right setup can turn your solar system into a 24/7 tool.
