Solar batteries are worthy additions to any solar power system in Australia. Ask any solar contractor and they’ll tell you that investing in them is an excellent way to get the most value from your solar panels.

The main reason for this is that they serve as a source of backup power. These batteries increase a property’s energy independence and can even help them save money in the long run.

Our team at Connected Solar Gippsland highly recommends people in the area to invest in quality solar batteries. We believe that doing so will allow you to maximise your savings to make the switch to solar worth it.

In this post, we’ll talk more about solar battery storage, the cost associated with it, and how long they last.  

How Much Solar Battery Storage Should I Get?

To know how much solar battery storage you should get, you’ll need to calculate your average daily electricity usage. This numerical figure will allow you to estimate how many kilowatt-hours of energy you’ll have to store, so you have power even at night time.

Calculating your solar battery storage before purchasing from any of the solar battery brands is important. Buying a battery your solar system can’t fill within a reasonable time is just a waste of money. Likewise, purchasing a smaller battery will result in you having to pay for the energy you need from the grid.

If you’re unsure how to calculate your energy usage at home, Connected Solar Gippsland can help. Our crew can come to your property to give advice on the best solar battery solution for you. 

How Much Does Adding a Solar Battery Cost?

A solar battery can cost anywhere between $4,500 to $18,000, depending on the size and capability. Solar batteries that have increased kilowatt-hour capacities will cost more.

Due to the high initial expense, it’s important to consider buying solar batteries carefully. The good news is that the continuous savings and increase in energy independence provided by these batteries make them worth the upfront cost.

You might notice that there are lower-priced solar batteries sold on the market today. The problem with these devices is that many of them aren’t complete and are only battery packs. This means that you’ll still have to purchase a solar inverter for the battery along with other components to make them work as intended.

How Long Do Solar Batteries Last?

A solar battery can last between 5 to 15 years. However, their longevity is mainly determined by their usage, temperatures in the area, and maintenance. The latter plays an essential role in making solar batteries last.

If you plan to purchase a solar battery today, you’ll most likely end up replacing them to match the 20 to 30-year lifespan of most solar power systems.
