Installing more solar panels is of course immediately positive for the environment, as your household will produce more clean energy, displacing more fossil fuel generated electricity. This is because batteries ultimately store electricity they don’t generate or produce any additional renewable electricity to what a household solar system produces. If you want to help the fight against climate change right now, then installing a battery at home doesn’t immediately reduce fossil fuel generated electricity in the grid. If the voltage gets too high, solar systems cannot export and solar generation is wasted.īattery systems can alleviate high voltage issues by reducing exports to the grid thereby minimising network costs which means savings for you and the community. Solar batteries benefit the communityĭrawing from batteries in the early evening reduces your demand on the grid at peak times, which could help your electricity network provider delay expensive capacity upgrades (which consumers pay for indirectly).Īlso, powerline voltage in some streets rises when everyone is exporting from their solar systems at the same time. Use more of your own solar-generated electricity, especially if you are often out during the day when your solar is generating and have high consumption in evenings and mornings (when it’s not). Find out how the Victorian Government’s Solar Battery rebate can help pay for part of the cost of a system so you can enjoy more savings on bills. An exception is where your battery’s cost is subsidised. However, the battery’s high initial cost means that these bill savings might be cancelled out for many households. With enough batteries and solar panels, imports from the grid can become rare events. Households may also be able to charge the battery with electricity purchased from the grid at off-peak rates for further savings on bills, although charging from solar would remain the priority.
Read the guide, do your homework and inform yourself before contacting installers for quotes or signing a contract.Īdding a battery will enhance your solar bill savings by being able to store solar-generated electricity for use later in the day.
The Solar Battery Buyers Guide has been produced in conjunction with non- profit organisation Renew External Link to help you plan the right system for your home. For more information visit our VPP Pilot Program page. Solar Victoria’s Virtual Power Plant Pilot Program makes it easier for Victorians to access VPPs. 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, using smart technology to meet local demand for grid electricity. 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. 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. If you meet the criteria we encourage you to consider adding a battery to your solar PV system. 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.įor more detailed information on the rebate and specific eligibility criteria visit our battery rebate page. 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. Household battery systems are expected to become more affordable in the next few years as tech advances help bring prices down. 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. 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.īattery 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. Victorians have embraced renewable energy at home, installing solar PV systems in record numbers.
