Can a Solar Battery Help Reduce Energy Bills?

‍

Rising electricity costs have encouraged many households to look more closely at how and when they use energy.

‍

Solar panels can reduce the amount of electricity bought from the grid during daylight hours, but any unused generation is usually exported. A solar battery allows you to store more of that electricity and use it later, which can help reduce energy bills further.

‍

How Does Solar Battery Storage Work?

‍

Solar panels generate electricity whenever there is sufficient daylight. Your home uses this electricity first. If the panels generate more than you need, the surplus can be directed into a battery rather than immediately exported to the grid.

‍

The stored electricity can then be used during the evening, overnight or whenever solar generation is low. As a result, you may buy less electricity from your supplier at times when your household demand is highest.

‍

Battery Storage can also be charged using grid electricity. Households on a suitable time of use tariff may be able to charge their battery when electricity is cheaper, then use the stored energy during more expensive periods. Actual savings depend on your tariff, consumption and battery settings.

‍

How Much Could a Battery Save?

‍

There is no single figure that applies to every property. Your potential savings will depend on the size of your solar panel system, the capacity of your battery and your daily electricity usage.

‍

A household that uses plenty of energy in the evening may benefit more than one where most electricity is consumed during daylight hours. Homes with heat pumps, electric vehicles or regular home working may also have higher electricity requirements, making careful battery sizing particularly important.

‍

Seasonal changes should be considered too. Solar panels generally generate more electricity during spring and summer, giving the battery more opportunities to charge from surplus solar power. During winter, charging from the grid on a cheaper tariff may become a useful part of the system’s operation.

‍

Can a Battery Be Added to Existing Solar Panels?

‍

In many cases, battery storage can be added to an existing solar panel system. The best arrangement will depend on the age of the installation, the inverter and the available space for new equipment.

‍

Battery storage can also be installed without solar panels. In this arrangement, the battery is charged from the grid during lower cost periods and used when electricity prices are higher. This can provide savings for households on compatible tariffs, although the results will vary.

‍

Modern battery systems also provide monitoring through an app, helping you see when electricity is being generated, stored and consumed. This information can make it easier to adjust daily habits and use more of your own stored energy.

‍

Is Solar Battery Storage Worth Considering?

‍

A correctly sized battery can reduce reliance on grid electricity and increase the amount of solar power used within your home. It may also provide greater control over when you buy electricity, particularly when combined with a suitable tariff.

‍

The financial return depends on installation costs, energy prices, household consumption and how effectively the battery is managed.
