Battery Storage

Battery storage lets you store electricity to use later, making your home more energy-efficient and less reliant on the grid. It pairs perfectly with solar panels but can also work on its own. In this section, you'll find clear answers about how battery systems work, how much they cost, and whether they're a good fit for your home.

Top 10 questions

What is a solar battery, and how does it work?

Solar batteries store extra energy from your solar panels, so you can use it when the panels aren't producing much electricity, like at night or on cloudy days. The panels turn sunlight into electricity, and the battery keeps any excess that you don't use straight away. This means you use less electricity from the grid, which can save you money.

Should I get a solar battery system for my home?

A solar battery system can be a good choice because it helps you store extra energy from your solar panels to use when you need it, like at night. This can cut your energy bills and make your home more self-sufficient. It's also good for the environment, as it reduces reliance on fossil fuels.

How does a solar battery save energy from my solar panels?

A solar battery takes any extra power your home solar panels make during sunny times and keeps it for later. When your panels aren't making enough power, like at night, the battery kicks in and powers your home. This helps you use less power from the grid and can lower your electricity bills.

Why should my small business have solar battery storage?

Solar battery storage helps your small business save money by storing solar power to use when electricity is more expensive. It keeps essential systems running during power cuts and reduces your carbon footprint, boosting your green reputation. Plus, there are UK incentives to lower upfront costs and help your business grow sustainably.

Can I save money on my energy bills with a solar battery?

Yes, a solar battery can help you save money on your energy bills. By storing excess energy from your solar panels for use later, you can rely less on electricity from the grid. This setup can cut your electricity bill by about 70% to 85%, which could mean savings of around £700 to £1,000 each year. Your exact savings will depend on your energy use, the size of your system, and how well you manage your stored energy.

What kind of batteries are best for solar panels?

Lithium-ion batteries are usually the best choice for solar panels. They're popular because they hold a lot of energy for their size, last a long time, and waste less energy when charging and discharging. Brands like Tesla Powerwall and LG Chem are well-known options.

How long do solar batteries last before you have to replace them?

Solar batteries usually last between 5 and 15 years. Their lifespan depends on how often you use them, how you maintain them, and what type of battery you have. This is shorter than solar panels, which often last 25 to 30 years.

Can solar batteries keep my home running during a power cut?

Yes, solar batteries can keep your home running during a power cut if they're set up to do that. They store energy from your solar panels, which you can use when the power's out. Just make sure your system is equipped with a suitable battery and an inverter that allows it to work independently from the grid during outages.

Can I add a battery to my solar panel setup?

Yes, you can add a battery to most solar panel setups. It’s quite common to do so. There are two main ways: using AC-coupled batteries that connect to your home’s electrical system, or replacing your inverter with a hybrid one that can manage both solar panels and batteries. Each option has its pros and cons, so it’s a good idea to check compatibility and consult a certified installer.

What size solar battery should I get for my home?

Solar batteries come in different sizes, like small (4-5 kWh) for lower energy needs, medium (8-10 kWh) for average homes, and large (10 kWh or more) for higher usage. To choose the right size, consider how much electricity you use, your solar panel capacity, and what you want from your battery, like maximising solar use or backup power during outages.
