What are solar batteries & how do they work?

Solar batteries store any unused electricity generated by your solar panels to be used later, such as at night when your panels aren’t working (Adobe) Solar batteries are energy storage devices designed to store the electricity generated by solar panels.

What is a solar battery?

A solar battery is a storage device designed to hold onto the excess energy your solar panels generate throughout the day. You can use this extra energy at times when the sun isn’t shining – such as evenings – or sell it to the grid through a solar export tariff.

Can you connect a battery to a solar panel?

You can connect batteries in series or parallel, with each option offering different tradeoffs. Much like connecting solar panels, it is a matter of what you are solving for, increasing the voltage or current. With batteries, though, there are a few basics you need to keep in mind before you proceed: Batteries use higher currents.

Do solar batteries work with solar panels?

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.

Do I need storage batteries for my solar panels?

Whether you need storage batteries for your solar panels depends on several factors. With a grid-tied system, you might not need storage batteries, as you can rely on supplied energy for backup power when your panels are not generating enough. Solar storage batteries become essential for off-grid systems or areas with unreliable grid connections.

Why should you buy a solar battery?

You'll be able to use more of the electricity you generate. 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.
