How much does a solar battery cost?

Solar batteries come with a hefty upfront cost. The actual cost will depend on your home and the size of the battery you want or need, but it can range between £1,000 and £10,000. You'll likely need two batteries during the life of your solar panels. Batteries last around 15 years, while solar panels last about 25 years.

Is a solar battery worth it?

It's incredibly difficult to quantify whether a solar battery will be worth it, as every household has different energy usage patterns. According to The Eco Experts, a typical three-bedroom home could save around £582 every year with a solar battery AND solar panel system. Yet most of this saving will come from the solar panels.

What is a solar battery?

Solar batteries are designed to work with solar panel systems. It's a device that stores the electricity you generate (but don't use immediately) from your solar panels, allowing you to then use that electricity later in the day.

Why should you buy a solar battery?

This should reduce your energy bills – and your carbon footprint. For example, if you're not at home during the day to use the energy your solar panels are generating, having a battery will enable you to store (and later use) energy from your solar panels. A solar battery means you can take advantage of cheaper electricity.

What is a good solar battery size?

Battery sizes are measured by how much solar electricity they can store, but generally, you shouldn't fully drain a battery, as it can damage it, meaning it'll likely need replacing sooner. Most modern batteries allow you to use 85% and 95% of the energy stored. So you'd expect a 8kWh battery to have a usable capacity of between 6.8kWh and 7.6kWh.

Can a solar battery be used as a car charger?

If you're an electric vehicle owner, you can use your solar battery as a car charger. Any electricity generated from your panels can be stored in your solar battery to then charge up your EV overnight. So is it worth getting a solar battery?
