When researching solar systems for your home or speaking to one of our experts to get a quote, you are likely to hear the phrase “solar panel battery” often, and while you might gain a slight understanding of what they are from conversations and reading, a comprehensive understanding will go a long way when it comes to designing and installing a solar panel system for your home.

As solar panels only work when there is sunlight, their function relies heavily on daytime. But with a solar panel battery, you can ensure your solar panel system works as efficiently as possible so that you make the most out of the renewable energy source during the evening and night and reap all the benefits of solar power.

In this blog, we are going to dive into the world of solar batteries, explaining how they work and why you need them as part of your system.

How A Solar Panel Battery Works

Solar batteries are an energy storage system that holds power while it isn’t needed.

Excess energy that is generated during the day is used to charge the battery. When your solar PV panels are no longer producing energy, at times when there is low to no sunlight, the stored energy in the battery is converted into electricity.

This equipment usually uses an inverter to convert the Direct Current (DC) generated by solar panels into Alternating Current (AC) that can be used by your household appliances.

The most common types of solar panel batteries are lithium-ion and lead-acid, with lithium-ion being preferred for their higher energy storage capacity and efficiency.

Why you need a solar panel battery

With over 1.2 million homes in the UK utilising solar power, it isn’t surprising that the number of solar panel batteries being installed is increasing. But why?

Adding a solar panel battery to your home’s solar panel system provides many benefits.

Energy Storage

Solar panels create all their energy during the daylight hours, making sense as they use the sun to generate power. However, not all this power is used at that time, meaning that the solar panels create excess energy. By installing a solar panel battery, you can store the excess energy produced and use it when the solar panels aren’t generating energy. This means you have a continuous power supply away from the grid.

Energy Independence

Solar panels and batteries enable you to reduce your dependence on the National Grid for energy. As you will be utilising excess energy when the sun isn’t out, you won’t need to rely on the National Grid to supply energy to your home in the evening or during the night. Not only can this help reduce energy bills, but it will also keep your home powered throughout power outages or grid failures.

Saving Money

Reducing reliance on the National Grid enables you to reduce reliance on third-party energy suppliers, leading to a reduction in your energy bills. By storing energy provided by your solar system, you won’t need to buy as much energy from your energy provider and, therefore, will save money on your bills.

In addition to this, if you live in an area with time-of-use electricity pricing, having a solar panel battery will enable you to store energy when prices are low and use it when prices are high.

Increased System Efficiency

Solar panel batteries can enhance the overall efficiency of your solar panel system by allowing you to use the stored energy when it’s most needed. This can result in a more optimised use of renewable energy.

Environmental Impact

Storing excess solar energy can help reduce reliance on non-renewable energy sources. It contributes to a more sustainable and environmentally friendly energy consumption pattern, reducing carbon emissions associated with conventional grid power.


As we become a more eco-conscious society and move away from the use of fossil fuels to provide us with energy, the energy landscape will change. Installing a solar panel battery now could help you future-proof your home and energy provisions, allowing you to be adaptable as regulations, grid configurations, and technologies change.
