Solar Program Efficiency: How Solar Victoria Measures Up

Looking at these numbers, it’s no wonder the U.S. had to set up a whole agency just to chase government waste. If this trend continues, Australia might need one too.

This chart compares how funds are allocated between public rebates and operating costs across different solar and energy programs:

• Solar Victoria 2023–24: 65% of funds went to rebates, 35% to operating costs.
• Efficient Program Example (Oregon): 93% of funds went to rebates, 7% to operating costs.
• U.S. Government Energy Programs Average: 66% of funds went to rebates, 34% to operating costs.

Understanding how much money actually reaches homeowners in solar rebate programs — versus how much is spent running the programs — is important for making sure renewable energy efforts deliver real value.
Here’s a detailed look at Solar Victoria’s 2023–24 operations, and how it compares to similar programs around the world.

Solar Victoria 2023–24: Expenses and Rebates

Solar Victoria’s 2023–24 financial report shows:

• Rebates Paid: $88.88 million (65% of total spending)
• Operating Costs (Admin, Salaries, Interest, IT, etc.): $46.74 million (35% of total spending)

In simple terms:

• About 65 cents out of every dollar Solar Victoria handled in 2023–24 went directly into public rebates.
• About 35 cents was spent running the agency itself.

Government Solar and Energy Rebate Programs: Typical Cost vs Rebate Ratios

Globally, government rebate programs aim to keep administrative costs low, but the real-world figures vary:

Typical government rebate programs spend 5–30% of funds on administrative costs.
Efficient programs (like Oregon and the UK’s ECO) manage to keep admin below 10%, while more complex programs (like U.S. energy rebates) see admin costs climb to 30% or more.

Private Sector Rebate Programs: Different Model

In private sector rebate and cashback promotions, the structure is different:

• Mail-in rebates (common with appliances and electronics) are often poorly redeemed — only 10–30% of customers claim the benefit.
• Digital cashbacks (like app rebates) are much better, with around 78% redemption.

Private companies tend to spend very little on administration, because most processing is automated.
However, the effective benefit delivery depends on how many people actually claim the rebate.

How Solar Victoria Compares

Compared to the most efficient programs worldwide (where 90–95% of funds reach the public), Solar Victoria’s 65% result shows higher operational costs than ideal.
It performs similarly to average U.S. energy programs (which often spend about 34% on administration).

Solar Victoria: An Unjustified Waste of Taxpayer Money

• Solar Victoria spent 35% of its 2023–24 budget on operational costs, with 65% paid out as public rebates.
• Well-run programs internationally (like Oregon’s vehicle rebate and the UK’s ECO scheme) keep admin costs under 10%, meaning more than 90% of funds go directly to households.
• Typical government energy programs around the world spend between 5% and 30% of their budgets on administration.
• Private sector rebates are often even cheaper to process, but many advertised rebates go unclaimed.

In global terms, Solar Victoria’s efficiency is average compared to large government programs, but significantly less efficient than the best-run public or private rebate systems.

Strong Solar Battery Uptake in the First Month of New Rebate Program

The Clean Energy Regulator’s Cheaper Home Batteries Program, launched on 1 July 2025, is delivering an early surge in demand. According to the latest figures:

• 19,592 battery systems were installed during July 2025, supporting a total of 344.1 MWh of capacity.
• The average battery size installed in that month was 18.2 kWh 

This uptake aligns closely with your earlier estimate of about 19,000 installations and 18 kWh per installation.

Financial Impact & Remaining Budget

• Rebate allotted per installation: approximately A$6,000
• Estimated cost committed so far:
  19,592 installs × A$6,000 ≈ A$117.6 million
• Total program funding: A$2.3 billion
• Remaining funds: approx. A$2.182 billion

Duration at Current Uptake Rate

Assuming installations continue at this same rate (~19,600 per month):

• Monthly rebate outlay: ~A$117.6 million
• Program duration at this pace:
  A$2.182 billion ÷ A$117.6 million ≈ 18.6 months
• Projected exhaustion: Around December 2026 or January 2027, if uptake remains constant.

When Uptake May Slow – Lessons from Past Programs

Drawing from earlier Australian solar and battery rebate schemes:

1. Early Surge Followed by Slowdown – Initial months attract early adopters; after 3–6 months demand often tapers.
2. Installer & Product Constraints – Shortages of installers, delays in grid approval or supply can reduce throughput 
3. Summer Holiday Dip – Installations typically slow in December–January, extending program duration.
4. Market Saturation & Payback Realities – After the initial enthusiasm, more cautious consumers often pause purchases.
5. Policy Adjustments – Rebate levels or eligibility criteria may be adjusted 12–18 months in, impacting demand.

If uptake declines by around 30% after six months (average ~14,000 installs/month):

• Monthly rebate draw: ~A$84 million
• Remaining funds (~A$2.182 billion) would last about 26 months, pushing program wrap-up to December 2027 or beyond.

When power consumption and solar production don’t align

I believe Solar Victoria is an absolute waste of taxpayer money.

It’s a politically driven creation that deceives people by claiming that grid-connected solar systems can genuinely save them money. It’s pure nonsense when power consumption and solar production don’t align with people’s home hours, and when you’re either exporting at 3 cents per kilowatt-hour or not exporting at all.

The same goes for battery systems, where the payback time stretches to 10 years or more. Solar Victoria looks like an incredible waste of money. I couldn’t find exact figures on how much it costs to run this organization, but I’m confident it costs more than the rebates they distribute.

The only solar energy system that makes sense for domestic use is an off-grid one. A system designed around household self-consumption: generating and storing solar electricity for use at home. The priority is meeting the household’s energy needs, rather than relying on income from exporting surplus power to the grid.

How Government Policies and Retailers Are Undermining Solar Adoption

The Solar Monopoly: Barriers for Small Businesses

Domestic solar energy is promoted but at the same time slowly being killed by government agencies like the CEC, Solar Victoria, grid operators, and electricity retailers. Here’s how it works in short: The CEC (Clean Energy Council) and Solar Victoria create barriers for small companies to enter the business. They’ve essentially created a monopoly—if you want your customers to access the Vic Solar rebate, you must become an “approved solar installer or retailer” and pay a fee.

The Rise of Two Types of Solar Companies

As you’d expect, most installers who actually design and install systems are excluded from this. This has led to the rise of two types of companies: those who really do the work but are forced to hire resources just to handle the paperwork, and a growing number of companies that are good with computers, have never seen an actual installation, and have no real idea how solar systems work. As a result, the real installers are paid next to nothing, while most of the profits go to the people sitting behind computers.

The Feed-In Tariff Trap: Selling Solar for Pennies

The next hit across Australia is the feed-in tariff, now as low as 3 cents per kWh. I’m sure that even those 3 cents are collected back from us in other ways. Here’s what’s happening: we invest in solar energy production, but electricity retailers successfully resell our power at good margins. There’s an argument that too much power is being generated on sunny days, and they can’t use it all, but my question is: why am I still paying peak rates when plenty of solar is being fed into the grid at 3 cents? And why do I have off-peak rates that start at 11 p.m. and finish at 6 a.m. when there’s obviously no solar available during those hours?

The Next Level: We Pay, We Give It Away, and Buy It Back at a High Price

Next, from October, any solar energy system must be controlled by grid operators or retailers, allowing them to turn it on or off whenever they want. Here’s how I see it now: if I buy a property and need power, I have to pay for the connection and equipment, like a transformer, and then it becomes the property of the grid operator. Then, I pay a daily rate just to have the connection, I pay for the electricity I use, and on top of that, if I install solar, I generate electricity, give it to the electricity retailer for free, and then buy it back at a much higher price. Isn’t that amazing?!

I understand that grid operators, electricity producers, and retailers have their own problems with the energy spikes on sunny days and various other challenges. But still, there’s a paradox here. I believe the only solar energy system that truly makes sense is an off-grid one. If there is a grid, it should be treated as a backup generator, not the main source of power.
