Solar Battery Storage in Cardiff (4)

Most homes without solar battery storage lose half of the energy generated by their solar panels.

Having a solar battery solves this problem by allowing you to store the surplus, ready for use at any time.

This means you’ll even have electricity during a power cut. You can even sell the extra energy to an energy company.

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.

However, exactly how much solar battery storage you'll need depends on the:

• Size of your home
• How much electricity you use
• 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

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

It's worth noting, solar panels can last up to 30 years, so you will most likely 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. To learn more about the cost of solar panel installation, check out our handy guide.
