Your solar panels are constantly working to convert energy from the sun into power for your home. When your panels are bringing in more solar energy than you need, solar battery storage is a great option.

Rather than losing that extra solar power, a solar battery can store the surplus, ready for use at any time.

You can even sell the extra energy to a local energy company.

Did you know that most homes without solar battery storage lose half of the energy generated by their solar panels?

Having a solar battery means you won't waste energy and you’ll even have electricity during a power cut.

Solar batteries have a range of different benefits that make any initial cost well worth the investment. They’re perfect for storing excess energy, reducing your carbon footprint and lowering energy prices.

With your solar battery storing energy during sunny days, you’ll have solar generated electricity even at night and on cloudy days. This means you won’t need to use any energy from your electricity company. You can also charge your battery during off peak hours and discharge it during peak hours, reducing your energy bills.

This depends on the size of your home, how much electricity you use and whether you plan to use any energy from your power company. If you plan to solely use solar energy in your home, you’ll need a bigger battery.

Larger homes that use more power will also require a bigger battery than small homes.

On average, most households in the UK use between 8 and 10 kWh of power each day. Solar batteries are available in a variety of sizes, ranging from 2.5kWh to 15kWh.

The lifespan of your solar battery storage will be affected by the size, type and capacity of battery you choose. Most solar batteries are designed to last up to 15 years.

Please note, solar panels can last up to 30 years so you may need to buy more than one solar battery to cover the lifespan of your panels.

Surprisingly, you don't need solar panels to use a solar battery. Your battery can be powered by electricity from your power company instead. However, in order to reap the benefits of using solar energy, you’ll need to have solar panels installed.

If you do decide to add solar panels to your home, you may be interested in the average cost. Most systems will cost between £5,000 and £8,000. To learn more about the cost of solar panel installation, check out our handy guide.

The price you pay for your solar battery storage will vary depending on a number of factors. So before setting a budget, consider the following variables:

• Size of your home - Larger homes need more electricity. This will increase your solar battery installation cost.

• Current set up - If you want to switch from fossil fuels to solar power, you’ll need to pay for solar panel installation as well as solar battery installation.

• Brand of battery - Different brands have different prices.

• Capacity of battery - The higher the capacity of your solar battery, the more it’ll cost to buy.

• Type of battery - Different types of battery will be priced differently.

• Location - Depending on where you live in the UK, labour prices will vary.

Solar battery installation cost

Bearing the above factors in mind, you can now look at some average solar battery installation costs. Assuming your battery power is 7kWh peak/5kWh continuous, the average cost of a standard battery is £5,000. If you choose to also add an inverter and solar panels, the average solar battery installation cost will increase to £12,000.
