Savings of $175,000 a year: The solar change every Aussie business with a big roof needs to know

Australian businesses sitting beneath thousands of square metres of unused roof space are being urged to stop treating their rooftops as dead space, with major changes to the Federal Government's solar incentive scheme set to dramatically improve the economics of commercial solar from October.
 

Jack Kapoor, founder and CEO of Agile Energy, said the expansion of the Small-scale Renewable Energy Scheme from systems of 100 kW to as large as 1 MW represents one of the most significant opportunities Australian businesses have had to slash their exposure to electricity costs.
 

Under the announced changes, businesses, manufacturers, farms, retailers, warehouses, logistics operators, schools, hospitals and community organisations could see the upfront cost of eligible medium-scale solar installations reduced by around 20 per cent.
 

"This is potentially a watershed moment for commercial solar in Australia because suddenly the enormous empty roofs sitting above factories, warehouses, shopping centres and other commercial buildings become incredibly valuable energy-producing assets," Kapoor said.
 

"For many businesses, the question is no longer whether they can afford to install solar, but whether they can afford to keep buying so much of their electricity from the grid when their roof could be producing it for them."
 

The numbers should make every CFO pay attention
 

According to figures released by the Federal Government, the expanded scheme could provide an estimated discount of around $68,000 on a 250 kW solar system and approximately $136,000 on a 500 kW installation.
 

The Government estimates that a 250 kW system on a medium-sized enterprise could generate around 345 MWh of electricity annually and potentially save around $50,000 in electricity costs each year.
 

For larger industrial energy users, an 850 kW installation could generate approximately 1,173 MWh annually, with estimated electricity cost savings of around $175,000 a year.
 

Kapoor said those figures should be commanding the attention of business owners, CFOs and boards across the country.

"Saving $50,000 or $175,000 a year isn't an environmental talking point, it is a commercial conversation about reducing operating costs, improving margins and making a business more competitive," Kapoor said.
 

"When governments are prepared to help reduce the upfront cost of infrastructure that could then materially reduce your operating expenses year after year, every business with a suitable roof should at least be investigating the numbers."
 

Australia has millions of solar homes, but business is lagging badly
 

Despite Australia becoming a global leader in residential rooftop solar, commercial uptake has failed to keep pace.
 

The Federal Government, citing analysis from the Institute for Energy Economics and Financial Analysis, said residential solar capacity has reached approximately 22 GW while businesses have installed around 5.6 GW, much of it through systems below 100 kW.
 

Kapoor said the disparity highlights the enormous untapped opportunity sitting above Australian businesses.
 

"Australians worked out years ago that putting solar on the family home could reduce dependence on expensive grid electricity, yet enormous commercial roofs capable of generating serious amounts of energy are still sitting there doing absolutely nothing," Kapoor said.
 

"We drive past factories, distribution centres, warehouses, supermarkets and commercial buildings every day with huge roof areas exposed to Australian sunshine, while the businesses underneath them continue buying enormous volumes of electricity from the grid.
 

"That is the opportunity this reform has the potential to unlock."
 

Your roof could become one of your hardest-working business assets
 

Kapoor said business owners need to change the way they think about commercial property.
 

"A roof has traditionally been viewed as something that keeps the weather out, but increasingly it should be viewed as productive infrastructure capable of generating energy and potentially delivering substantial financial value," Kapoor said.
 

"If you have a large roof and significant daytime electricity consumption, you may effectively be sitting underneath an energy asset you haven't activated yet."
 

He said the opportunity becomes even more compelling when solar is considered alongside batteries and intelligent energy management.
 

"Solar is only one part of the equation because businesses can increasingly generate electricity, store it, manage when they draw from the grid and reduce damaging demand peaks," Kapoor said.
 

"The businesses getting this right aren't simply installing panels, they are redesigning the way they buy, generate, store and use energy."

Don't wait until October to start thinking about it
 

The expanded SRES is expected to commence from 1 October 2026, subject to the necessary regulations being put in place.
 

Kapoor warned businesses against assuming this means they should wait until October before investigating their options.
 

"A commercial solar project isn't something you should start thinking about the morning a new incentive becomes available because there is considerable work involved in understanding consumption, analysing tariffs and demand, assessing the site, designing the right system, examining network requirements and establishing the commercial case," Kapoor said.
 

"Businesses should be doing the analysis now so they understand what their site could support, what the economics potentially look like and whether they may be positioned to take advantage of the changes once they commence."
 

The businesses that move first could gain a competitive advantage
 

Kapoor believes the reforms could create a significant divide between businesses that actively manage energy and those that continue treating electricity as an unavoidable overhead.
 

"Energy is increasingly becoming a competitive issue because two businesses selling exactly the same product can have dramatically different operating costs depending on how intelligently they manage electricity," Kapoor said.
 

"If your competitor is generating a meaningful proportion of its own electricity while you remain heavily exposed to grid prices, that difference eventually finds its way into margins, pricing and competitiveness.
 

"This is why commercial solar needs to move out of the sustainability department and onto the desks of CEOs and CFOs."
 

Stop paying for electricity you could be producing yourself
 

Kapoor said Agile Energy is encouraging commercial and industrial organisations to undertake an assessment of their existing electricity profile and rooftop potential.
 

"Businesses should be asking some very simple questions: how much electricity are we buying, when are we using it, what are our demand charges costing us, how much suitable roof space do we have and what would solar and battery infrastructure potentially do to those numbers?" Kapoor said.
 

"For businesses with the right energy profile, the answers can be extraordinary. The Government has effectively sent Australian business a very clear message: put your rooftops to work. Now business owners need to work out what their roof could be worth."
