When Do Solar Batteries Need To Be Replaced?

Auswell Energy explains when you need to replace your solar batteries.

Solar batteries are handy additions to Queensland homes: they can provide power for your home if the grid is down, and they collect ample energy because of the sunny weather we enjoy for most of the year. Take advantage of the 2999 hours of sunshine every year!

Before giving the go-ahead, you may be wondering how much time you will get out of your batteries before they need to be replaced. If you’re looking to install solar batteries in Brisbane, here’s everything you need to know about their lifespan.

How long will my solar batteries last?

In general, you can expect your solar batteries to last between 5 and 15 years. This time range varies depending on a number of different factors, including what type of battery you install.

At Auswell Energy, we recommend and stock the Tesla Battery, as it has a 10-year warranty – meaning you won’t have to worry about purchasing a new battery for a decade.

Factors that impact the lifespan of your batteries

Other than the type of battery you have installed, there are many factors that can impact its lifespan. These include:

  • How often you use the battery – Just like any electronic device, your battery won’t last as long between charges as time goes on. The more you charge and use the battery, the less time it will last.
  • The battery’s surroundings – Extreme heat and cold, as well rainy weather, can negatively affect the lifespan of your battery. This is something to keep in mind in the scorching Brisbane summers. To combat this, consider having it installed in a covered, well-protected location.
  • Running your battery flat or over-charging – Both running your battery until it’s completely flat or over-charging your battery constantly can decrease its lifespan. Make sure you’re paying attention to how much energy you are using from it and adjust the charging accordingly.

How do I know that my batteries need replacing?

In general, if your battery is no longer meeting your energy requirements when it is in use, it’s time for it to be replaced. Again, most solar batteries last between 5-10 years, so if you’re having problems before this time, you should have it inspected by an expert. Remember to also check your warranty.
