What is solar battery storage?

For those who aren’t yet in the loop, a solar battery is essentially just that – a battery that stores power generated by your solar panels.

In the past, solar energy that was not immediately used by your household would be exported to the grid in exchange for a solar feed-in tariff. But now, homes that have a battery installed can store this energy for their own use later on.

How to choose the best solar battery

Now that you know the best solar battery companies in Australia, how do you choose which one to go with? Here’s a list of considerations before you buy:

Price

One of the main considerations when buying a solar battery is its cost. Consider your budget alongside potential long-term savings when purchasing a battery.

Battery capacity

The bigger your battery’s capacity, the more power it can have on standby for when you need it most. Consider the size of your home and predicted usage when choosing a solar battery company.

Efficiency

Efficient solar batteries use less power than other, lower efficiency batteries. While it may cost more to initially purchase an efficient battery, you’ll be saving power and money in the long run.

Warranty

A solar battery is a big investment and while most companies offer a warranty of around 10 years, some go as high as 20. Ideally you want an affordable battery with as long a warranty (or high usage limit) as possible.

Mobile app

Apps are an easy way of keeping an eye on your solar battery system. Consider purchasing from a company that has an app for hassle-free system monitoring.
