It's advisable to seek quotes from professional installers for accurate cost estimates based on your specific circumstances.
FAQ 9: Can I retrofit a solar battery to my existing solar PV system in Australia?
Yes, you can retrofit a solar battery to your existing solar PV system. Retrofitting involves adding a battery storage system to your current solar panel setup. However, there are few considerations to be made to ensure that the battery will be compatible with the current solar system.
FAQ 10: How do grid-connected solar battery systems interact with the electricity grid in Australia?
The interaction between your solar battery system and the electricity grid aims to optimize energy usage, reduce reliance on grid power, and potentially earn you credits for excess energy you provide back to the grid. This setup enables homeowners to make the most of their solar energy generation and enhance overall energy efficiency. 

  • Energy Generation: During sunny hours, your solar panels generate electricity from sunlight. Any excess energy not immediately used in your home is sent back to the grid.

  • Energy Consumption: When your home's energy demand exceeds what your solar panels are producing (at night or during cloudy periods), you draw electricity from the grid.

  • Battery Charging: If you have a solar battery system, excess energy generated by your solar panels can be stored in the battery instead of being sent to the grid. This energy can be used later when the sun isn't shining.

  • Battery Discharging: When your solar panels aren't producing enough energy, or during peak usage times when electricity costs are higher, you can draw energy from your battery instead of the grid.

  • Feed-In Tariffs: If your battery is fully charged, and your home's energy demand is low, any surplus energy generated by your solar panels can be fed back to the grid. You might receive feed-in tariffs or credits for this exported energy.

  • Smart Grid Support: In some cases, grid-connected solar batteries can also provide support to the grid during periods of high demand or stress, if they are part of VPPs (Virtual Power Plants). This is known as grid balancing and can be very attractive for homeowners, generating an additional income which can lead to positive electricity bills, where you retailer will send you a cheque, instead of you paying for electricity.

FAQ 11: Can I sell excess energy from my solar battery back to the grid in Australia?
