Victorians have embraced renewable energy at home, installing solar PV systems in record numbers. Some of these households are ready to take the next step and invest in an energy storage system to make the most of the solar electricity generated throughout the day.
Battery technology has developed rapidly in the last few years, giving more options to solar households connected to the grid to store their own renewable energy in a battery. Households can use solar-generated electricity at a later time to reduce their bills, charge their battery at times of the day when grid electricity is cheaper, or install a system designed to provide backup during a power outage.
Household battery systems are expected to become more affordable in the next few years as tech advances help bring prices down. Until then installing a battery system might not make financial sense to all households, with a system often unlikely to pay for itself before the end of its warranty period.
The Victorian Government is encouraging households to install battery systems with a Solar Battery Rebate, to make the cost of adding a battery more affordable to current solar PV households.
If you meet the criteria we encourage you to consider adding a battery to your solar PV system. Use the information in Section 5: Working out the costs and benefits of a solar battery system, to work out the financial equation on solar and batteries at your house. Solar PV with batteries doesn’t suit all households just yet, but it might be a perfect combination for you, and could set you up for significant savings on energy bills for many years to come.
Once a battery system is installed, households may want to consider joining an Aggregation program or a Virtual Power Plant trial (VPP) , where a large number of rooftop solar panels and battery storage systems are linked across a region, using smart technology to meet local demand for grid electricity.
The Solar Battery Buyers Guide has been produced in conjunction with non- profit organisation to help you plan the right system for your home. Read the guide, do your homework and inform yourself before contacting installers for quotes or signing a contract.
