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 do solar panels use batteries?

The batteries have the function of supplying electrical energy to the system at the moment when the photovoltaic panels do not generate the necessary electricity. When the solar panels can generate more electricity than the electrical system demands, all the energy demanded is supplied by the panels, and the excess is used to charge the batteries.

How does a solar panel battery work?

At its core, a solar panel battery works in a three-step process to generate, store, and then utilise power for a home. While the basics of taking energy and storing it for later use are the same for all kinds of units, the exact nature of battery storage technology will vary depending on the type of coupled storage inverter being used.

Are solar batteries worth it?

A battery for a three-bedroom property tends to cost around £4,500, which, combined with the costs of a solar panel system, can be a barrier for many. However, solar batteries are worth it if you want to reduce your reliance on grid electricity because they allow you to store the electricity generated by your solar panels.

What kind of batteries do solar panels use?

Lead acid batteries. These deep cycle batteries were the most common option for solar panels since their inception. Like the batteries in your combustion engine vehicle, they are affordable and recyclable. They do, however, need occasional maintenance. The efficiency of lead acid batteries is considerably less than lithium ion batteries.

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.
