Solar Panel Battery Storage Explained

Understanding Solar Panel Battery Storage

As the cost of living rises, you may look at ways to lower your energy costs and reduce your carbon footprint. Investing in solar panels is a great way to ‘go green’ and save money in the long run, but if you want to maximise solar energy and come off the National Grid completely, solar panel battery storage is the way to go. Let’s find out more.

Storing Solar Energy in Batteries – How Does it Work?

Many modern solar power systems come with a battery connected to them which can store excess energy for later consumption. This helps to generate clean energy in periods of high demand or after dark. You’ll even have energy during a power cut. Essentially, you don’t have to rely purely on sunlight being present in order to heat your home economically.

But how does storing solar energy in batteries actually work? Well, when your solar panels generate electricity that you don’t need to use straight away, a battery will convert this DC electricity into AC power and store it. Your solar panels charge the battery for use when you need it, helping to reduce or eliminate your reliance on the National Grid. The science behind solar panels is fairly complex and involves a chemical reaction within a lithium-ion battery. But all you really need to know is that solar energy generated in the day won’t go to waste.

How Long Can Solar Power Be Stored in a Battery?

Solar panel batteries for home use are an extremely clever addition to solar panel systems. Generally, a standard solar battery will hold a charge for 1-5 days, depending on the type of battery connected to your solar panels. Seeing as there is sunlight every day of the year – even through winter – your solar battery will constantly be charging.

What Size Battery Do I Need for Solar Panels?

Each home’s individual energy needs are different, and the type of battery you get will depend on the size of your property. For example, a one-bedroom property would require a 2kWh battery as minimal power is needed for a small space. A four-bedroom property, however, may require a 9kWh battery. The bigger the battery, the more solar energy it can store.

How Long Do Solar Batteries Last

Standard solar batteries last 15-30 years (depending on the type you buy), making them a great investment. Not only will you not have to worry about replacing the batteries regularly, but you’ll be able to save money in the long run by not relying on National Grid prices. Going green with solar panels has an initial cost, but afterwards, you’ll start to reap the benefits.
