What Is A Solar Battery?

A solar battery is a power storing device that can be charged by the energy your solar panels generate. This energy is saved for later use during times your solar system is not producing enough energy to power your needs. This is common during low sunlight times such as early mornings and evenings.

Depending on your individual circumstances and power usage, more often than not you will find your solar system will produce more power than you are using. Without a battery storage device, this excess power gets fed or sold back to the grid at. This sounds all well and good, however, your electricity provider will almost always sell the power back to you at a much higher rate than you sold it for. eg your energy provider will buy off you at 8 cents and sell to you at 28 cents.

With a battery storage system in place, rather than selling your excess power back to the grid, you store it on your battery for use whenever you need it during periods of low light conditions. This reduces your dependency on the grid making the battery storage option a more cost effective solution in the long term. The only time you will need to draw power from the grid is when your battery is depleted.

How Does A Solar Battery Work?

The energy your solar system draws from the sun via the solar panels is called the DC (Direct Current) power. By way of a device called an inverter, the DC power is converted to AC (Alternating Current) power. The AC power is what is required to run electrical appliances in your home or office. The AC power gets stored on your batteries for later use.

There are some batteries on the market that have their own inverter which mean they can convert the DC to AC without the need of additional components. These batteries are called AC batteries.

Latest technology has seen hybrid battery systems being made available on the market which can be described as an all in one battery unit. These storage systems in some cases can eliminate the need for a typical solar inverter altogether.

The very first solar battery storage system in the world was developed by Telsa called the Telsa Powerwall, but there are now many other batteries available today. Choosing the right one for you will depend on your individual circumstances. We always recommend seeking advice from a professional before making your purchase.
