What Are Solar Batteries and How Do They Work?


Solar batteries store the excess energy generated by your solar panels during the day, which can then be used in the evening or during power outages. Instead of sending surplus energy back to the grid, you can store it for later use, maximising your energy efficiency.

Benefits of Solar Batteries

  • Lower Energy Bills: By storing and using your own solar energy, you reduce the amount of power you need to purchase from the grid.
  • Blackout Protection: Keep your lights and essential appliances running during power outages with reliable battery backup.
  • Environmental Impact: Solar batteries further reduce your reliance on fossil fuels, making your home even more eco-friendly.


Is It a Smart Investment?


While solar batteries offer multiple benefits, the return on investment (ROI) can be challenging. The current cost of solar batteries often means that the time it takes to recoup your investment may exceed the battery's warranty period. However, if you highly value energy independence and environmental benefits, a solar battery might still be the right choice for you.

Frequently Asked Questions

  • Are solar batteries worth it in Australia?

    In many states, feed-in tariffs for exporting solar energy back to the grid are relatively low compared to the cost of buying electricity at night. A solar battery allows households to store excess solar power generated during the day and use it later, reducing reliance on the grid and lowering overall electricity bills. Homes with higher evening energy usage often see the greatest financial benefit. 


    Batteries can also provide backup protection during power outages, which adds value in areas prone to blackouts. The overall return on investment depends on system size, installation cost, available government rebates, and long-term energy goals.

  • How long do solar batteries last?

    Most modern solar batteries are designed to last between 10 and 15 years, depending on the type of battery, usage patterns, and environmental conditions. Lithium-ion batteries, which are the most common type used in residential solar systems, typically come with a 10-year manufacturer warranty and are built to handle daily charging and discharging cycles. 


    Over time, battery capacity gradually decreases, meaning it may store slightly less energy than when it was new. Proper system sizing, professional installation, and correct settings can help maximise lifespan. Many manufacturers also specify a minimum performance level that the battery should maintain throughout the warranty period.

  • Do solar batteries work during a blackout?

    Many modern solar battery systems are capable of providing backup power during a blackout, but this depends on how the system is designed and installed. Standard grid-connected solar systems without battery storage typically shut down during an outage for safety reasons. However, when a battery with backup functionality is installed, it can automatically detect a power outage and switch to stored energy. 


    Some systems can power the entire home, while others are configured to supply electricity to essential appliances only. The duration of backup power depends on how much energy is stored in the battery and how much electricity is being used during the outage.

Government Rebates and Incentives

Various state rebates and incentives are available to help offset the cost of solar batteries. Our team at Des Mullins Electrical & Solar can help you navigate these options, including our tailored solar finance solutions to make the most informed decision.
