Solar Battery Discounts Raise Questions Among Solar Panel Users
updated June 15, 2025
Homeowners looking to reduce their electricity bills by installing solar panels are now evaluating whether recent discounts on solar batteries make them a worthwhile investment.
The federal government’s Cheaper Home Batteries Program, set to begin July 1, will provide a 30% reduction in upfront costs for qualified small-scale battery systems.
Though, some residents who invested in solar panels years ago, like Lee Bolger of Victoria, are skeptical. They’ve seen significant decreases in feed-in tariffs, which are credits from energy companies for excess electricity sent back to the grid.
Adam Corrigan, an energy efficiency specialist and founder of Your Energy Freind, advises homeowners to consider their unique circumstances and explore other energy-saving options before investing heavily in solar panels and batteries.
Bolger, who lives in Great Western, Victoria, installed 30 panels on his eight-bedroom home in March 2023. He rents out rooms and says his tenants use a lot of electricity for air conditioning and heating.
His 12-kilowatt system cost $12,680 after rebates and discounts,which he estimated he could recoup in about six years.But his feed-in tariff has dropped from 12 cents per kilowatt-hour (kWh) to around 6 cents.
Comparison website finder reports that minimum feed-in tariffs in Victoria will drop to 0.04 cents from July 1, though better rates may be available depending on the provider. Fifteen years ago, these tariffs were as high as 60 cents.
SolarHub in May.” >Bolger estimates his original 12c per kWh feed-in tariff would have saved him about $1,000 a year. Combined with the $1,000 worth of electricity he saves by using his own system, he receives a total benefit of $2,000 annually.
If the feed-in tariff drops to almost zero, his benefit will decrease to around $1,000 a year, possibly doubling the time it takes to pay off his panels. He says this experience has made him “indifferent” to the economic benefits of solar, and he won’t be recommending it to others.
Bolger doesn’t believe installing a battery will help because his solar panels won’t generate enough excess energy to store, especially in winter when it’s often raining and dark.
“My summer bills were ridiculously low. In winter, you will not generally get enough charge into the battery to make a big difference,” he said.
Corrigan says other households may be in a diffrent situation. The average NSW home uses about 20kWh of electricity per day. Corrigan, who has a 1.5 kilowatt solar system, says he uses less than 10 kilowatt-hours a day, though his cooktop is gas-powered.
“[For] most homes, a 10 kilowatt or 14 kilowatt battery will get you through the night easily,” he said. “Though, if you are cranking your air conditioner and you’ve got ducted air conditioning, it’s problably onyl going to last you two, three hours.”
Corrigan says batteries will work for some households, and the new federal rebate makes them more affordable.
A battery can be very practical since it allows storage of the surplus electricity generated around midday, which can later be utilized in the early evening.
Finder estimates the cost of a 10kWh battery could decrease to between $6,713 and $8,904 due to the federal discount.
“In Australia,the average household uses about 15 to 20kWh of electricity per day,” a Finder spokesperson said.
“If most of your energy consumption is in the evening and you’re paying a single electricity rate — let’s use 32.34c per kWh as an average based on single-rate plans in our database — then with a 10kWh battery and using 80 per cent of its capacity, you could save about $850 a year,” the spokesperson said.
“However,the actual savings can vary depending on the type of electricity plan you have,the rates you pay,your solar panel setup,your energy consumption patterns,and how much electricity you export back to the grid.”
While the federal battery discount is national,states and territories also have programs that can further reduce the cost.
Corrigan recommends considering other options before investing in expensive solar panels and battery systems. He suggests Bolger review his insulation and energy efficiency measures to reduce his electricity consumption.
Corrigan recommends households first analyze their power bills and shop around for the best deal. Making your house more energy-efficient should be the next priority before considering solar panels and, batteries.
If you want to make your home more comfortable, get your insulation sorted and do your draft proofing. That’s your best return on investment. That’s your best bang for buck.
Corrigan says simple changes, such as installing heavy-lined curtains and a box pelmet, can effectively keep your home warm and are much cheaper than double-glazed windows.

Using a thermal camera around the home can also reveal gaps in roof insulation where batteries might have been moved.
“You only need a 5 per cent gap in that insulation blanket, and the effectiveness of that insulation — the whole blanket — diminishes by almost a half,” Corrigan said.
“When you get into bed tonight and you pull the doona up,just cut some holes in it,see how well it works.”
When considering whether to invest in a battery system, Corrigan says the first consideration is cost, as they are expensive and many people don’t have the money sitting in the bank.
Those who already have a solar system should check whether their inverter is battery-compatible, as this could raise warranty issues if it needs to be replaced.
Another consideration is what your next car will be.
Corrigan says in one to two years, electric vehicles will be capable of vehicle-to-home and vehicle-to-grid functionality, allowing EV batteries to be used to power your home.
“Some people are already doing it,” he said.
They are an attractive option because EV batteries generally have a huge capacity of around 50-70kWh.
“You could run your home for days on it.”
What’s next
Homeowners should carefully evaluate their energy needs, explore alternative energy-saving measures, and compare electricity plans before investing in solar batteries, even with the new federal discounts. The long-term benefits depend on individual circumstances and evolving energy technologies.
