Check your rebate eligibility
TL;DR: Solar is not the right move for every family right now, and that is okay. But for households already spending $400 or more per quarter on electricity, the maths often works out, especially with interest-free payment plans that require no upfront cost. The federal STC rebate knocks $2,500 to $3,500 off the price, and staged upgrades let you start small. This article covers who solar genuinely helps, what it actually costs in 2026, and when waiting is the smarter decision.
I want to start by saying something that solar companies rarely do: if you are under serious financial pressure right now, adding any new commitment to your household budget might not be the right call. That is a completely valid position, and nobody should make you feel otherwise.
With that said, energy bills are not optional. They are one of the few household costs that families cannot simply cut out. And for a lot of Australian households, electricity has become one of the most frustrating line items in the budget, because even when you are careful with usage, the bills keep going up.
That is the tension at the heart of this topic. Solar costs money to install. But electricity costs money every single quarter, indefinitely. The question is not really “can we afford solar?” It is closer to “can we reduce a cost we are already paying, without making things worse?”

The pressure is real, and it matters
Australian households are dealing with a combination of pressures that make any spending decision feel risky. Interest rates have pushed mortgage repayments up significantly. Groceries, insurance, and childcare have all increased. Many families have shifted into survival mode, focused entirely on cash flow and cutting back wherever they can.
In that context, telling someone they “should just get solar” is tone-deaf. What is actually helpful is laying out the numbers honestly, explaining what options exist for reducing or eliminating the upfront cost, and being clear about when solar helps and when it does not.
Because here is the thing about electricity: unlike a gym membership or a streaming subscription, you cannot cancel it. Higher tariffs and rising daily supply charges mean that even households using less power are seeing bigger bills. That is why energy costs tend to become the focus when budgets tighten. Not because families want to spend money on solar, but because they are already spending money on power and want it to stop climbing.
What solar actually costs in 2026
The sticker price of a solar system is not what you pay. The federal government's Small-scale Technology Certificate (STC) rebate is applied as a point-of-sale discount, reducing the cost before you hand over any money.
| System size | Before rebate | After STC rebate |
|---|---|---|
| 5kW | $5,500–$7,500 | $3,500–$5,000 |
| 6.6kW (most common) | $6,500–$9,500 | $4,500–$7,000 |
| 10kW | $9,000–$13,000 | $6,500–$10,000 |
| 13kW+ | $12,000–$17,000 | $9,000–$13,500 |
These are indicative prices for quality Tier 1 panels with a reputable inverter and proper installation. Cheaper systems exist, but cutting corners on solar often means problems within 5 to 7 years that cost more to fix than you saved upfront.
One important note: the STC rebate reduces each year and is legislated to end entirely by 2030. So while waiting for a “better deal” might feel sensible, the rebate you receive will be smaller next year than it is today.
Interest-free payment plans: the option most people overlook
The biggest barrier to solar is the upfront cost. But in 2026, a growing number of families are installing solar with zero money down, using interest-free payment plans offered through providers like Brighte, Humm, and Plenti.
Here is how the maths typically works for a household spending $500 per quarter on electricity (which is increasingly common).
In this scenario, the household is cash-flow positive from month one. They are not adding a cost; they are swapping one expense (electricity bills) for a smaller one (loan repayments plus reduced electricity). After the plan is paid off, the savings are entirely theirs.
This does not work for every household. If your electricity bills are already low (under $250 per quarter), the savings from solar may not cover the repayments, and you would be adding to your monthly costs in the short term. That is a situation where waiting may genuinely make more sense.
Staged upgrades: you do not have to do everything at once
One of the most common misconceptions is that solar is all-or-nothing. It is not. A staged approach can be one of the smartest ways to manage costs, especially for families who already have an older system or who cannot justify a large outlay right now.
Stage 1: Panels only
Start with a quality panel and inverter system. This delivers the biggest bang for your dollar and starts reducing bills immediately. Make sure the inverter is battery-ready so you can add storage later without replacing it.
Stage 2: Optimise your usage
Shift heavy appliances like washing machines, dishwashers, and pool pumps to run during daylight hours when your panels are generating. Add timers or smart plugs for around $20–$50 each. This costs almost nothing but can significantly increase how much solar power you use directly.
Stage 3: Add a battery (when it makes sense)
Battery prices are still coming down. For many households, adding a battery in 2 to 3 years will be more cost-effective than buying one today. When the time comes, a battery lets you store daytime solar for evening use and can reduce your grid reliance to near zero.
Stage 4: Replace a failing inverter
If you already have solar but your inverter has died or is underperforming, replacing just the inverter (typically $1,500–$3,000) can restore your system to full output without the cost of a complete new installation.
For families under financial pressure, doing nothing expensive right now is a perfectly valid decision. Small changes like shifting usage patterns or replacing a failing inverter can still reduce bills meaningfully without any major outlay.
Batteries: genuinely helpful or expensive luxury?
Batteries are often positioned as the answer to rising power prices. The reality is more nuanced. A home battery system costs $10,000 to $16,000 installed, and the payback period is typically 8 to 12 years. For a household that is watching every dollar, that is a significant commitment with a long wait before it pays for itself.
Some households do see genuine value from batteries, particularly those with high evening usage, low feed-in tariffs, or time-of-use electricity plans where peak rates are expensive. But for many families, solar panels alone deliver the fastest return. Adding panels and shifting usage into the day can achieve 60 to 80% of the savings a battery would provide, at a fraction of the cost.
If money is tight, panels first, battery later is almost always the right call.
Rebates and state programs that reduce upfront cost
Beyond the federal STC rebate, several states run their own programs that can make solar more accessible for families under financial pressure.
| State | Program |
|---|---|
| Victoria | Solar Homes Program: interest-free loans up to $1,400 for eligible households |
| South Australia | Retailer Energy Productivity Scheme (REPS): subsidies for low-income households |
| New South Wales | Energy bill relief and Peak Demand Reduction Scheme incentives |
| Queensland | Regional and remote solar programs, plus battery booster grants |
| All states | Federal STC rebate: $2,500–$3,500 off upfront cost (reduces annually until 2030) |
State programs change regularly, and eligibility criteria vary. It is worth checking what is available in your area before making a decision. Our rebate eligibility quiz can help you find out what you qualify for in a couple of minutes.

When solar genuinely helps families under pressure
Solar tends to make the most difference for households where energy bills are a significant, ongoing burden. Not a minor inconvenience, but a genuine source of stress every quarter. If that sounds familiar, and you meet a few of the following criteria, solar is likely worth exploring seriously.
Your electricity bill is consistently over $400 per quarter
Someone is home during the day (or you can shift usage with timers)
You plan to stay in the home for at least 4 to 5 years
Your roof gets reasonable sun and faces north, east, or west
You can access an interest-free payment plan or have savings set aside
If most of those apply, solar is less like buying something new and more like reducing an ongoing cost. The upfront investment is real, but the return comes in the form of lower bills every quarter for 20 to 25 years.
When waiting is the right call
It is equally important to say this clearly: waiting is not failing.
For some families, the cash flow simply is not there right now. Even with interest-free plans, taking on a new financial commitment when you are already stretched can create more stress than it solves. If any of these describe your situation, it is completely reasonable to hold off.
You are already managing multiple debts or repayments
Your electricity bills are relatively low (under $250 per quarter)
You are renting, or uncertain whether you will stay in the property
You do not have access to interest-free finance and cannot manage the upfront cost
Your household finances need to stabilise before adding any new commitment
Solar should never add stress to a household that is already stretched. If the timing is not right, that is okay. The technology will still be there when your situation changes, and while the rebate will be smaller, the equipment will likely be just as good or better.
The risk of getting it wrong matters more right now
During a cost-of-living crisis, the biggest risk is not missing out on solar savings. It is over-committing, buying the wrong system, or locking money into an upgrade that does not actually reduce your bills.
Pressure-free advice matters more than ever right now. A good solar company will not rush you into a decision or push upgrades you do not need. They will look at your bills, your roof, your usage patterns, and your budget, then tell you honestly whether solar makes sense for your situation. If they skip that step and jump straight to a quote, that tells you something about their priorities.
Families do not need to be told that solar is “the answer.” They need to understand whether it helps their specific situation, right now, with their actual numbers.
A better way to think about solar right now
Instead of asking “can we afford solar?” a more useful question is: “can we reduce a cost we are already paying, without increasing financial pressure?”
Sometimes the answer is yes. An interest-free plan covers the upfront cost, the savings exceed the repayments, and you come out ahead from month one. Sometimes the answer is no, and that is equally valid. Either way, making that decision from a place of understanding rather than sales pressure is what matters.
Australia's cost-of-living crisis has changed how families make decisions, and solar is no exception. It can help some households reduce long-term energy costs. It will not solve every financial problem. And it should never be rushed or oversold.
Frequently asked questions
Can you afford solar during the cost-of-living crisis?
It depends on your situation. A 6.6kW system costs $4,500 to $7,000 after the STC rebate. Interest-free payment plans from providers like Brighte and Humm can spread that over 2 to 5 years with no upfront cost. For households with electricity bills over $400 per quarter, the savings often exceed the repayments.
What solar rebates are available in 2026?
The federal STC rebate reduces the upfront cost by $2,500 to $3,500. Some states offer additional programs: Victoria has interest-free loans, South Australia offers low-income subsidies, and Queensland has battery booster grants. The federal rebate reduces each year until it ends in 2030.
Are interest-free solar payment plans worth it?
For many families, yes. Providers like Brighte, Humm, and Plenti offer plans over 2 to 5 years with no upfront cost. If your electricity bill is $400 or more per quarter, the savings from solar typically cover the repayments, making you cash-flow positive from day one.
Is it better to wait for solar prices to drop?
Panel prices have largely stabilised. Meanwhile, the STC rebate shrinks each year and electricity prices continue rising. For most households, waiting means higher power bills now and a smaller rebate later. That said, if your finances are genuinely stretched, waiting until you are more stable is a reasonable choice.
Can I add a battery later?
Yes, and it is often the smartest approach. Install panels first to start saving, then add a battery in 2 to 3 years when prices come down further. Make sure your inverter is battery-ready so the future upgrade is straightforward and does not require replacing equipment.
How much does solar actually save on electricity bills?
A typical 6.6kW system saves $1,200 to $2,000 per year, depending on usage patterns, location, and feed-in tariff rates. Households that use more power during daylight hours save more. With electricity prices continuing to rise, these savings increase over time.
