Ultra-Low-Cost Solar PV Research and Development – Round 4
$60M is available to cut utility-scale solar costs. Must be Australian-based to apply.

If you’re working on breakthrough solar tech — from next-gen cells to fully automated installation systems — this $60 million funding round from ARENA could help you scale. It’s aimed at Australian innovators who can push utility-scale solar costs below $20/MWh.
The Ultra-Low-Cost Solar PV Research and Development – Round 4 is part of ARENA’s Research, Development and Commercialisation (RDC) Program.
It offers $60 million in competitive grant funding to projects that can deliver on Australia’s “30-30-20” vision:
This is the fourth funding round, building on earlier successes in driving solar innovation from lab concepts to large-scale commercial deployment.
Eligible applicants include:
Technology Readiness Level:
Example fits:
ARENA isn’t just looking for interesting solar ideas — they want technologies that can materially drive down the cost of utility-scale solar PV. If your project can help hit the “30-30-30” target (30% efficiency, 30 cents/W installed, $20/MWh LCOE) and has a credible pathway to large-scale deployment, you’re in the zone.
The funding is split into two streams:
Ideal projects in this stream:
Competitive edge tip:
Projects that combine high efficiency + low cost + manufacturability will score highest. If it only ticks one box, it’s likely to fall short.
ARENA will favour projects that:
Competitive edge tip:
If your solution can be rolled out across multiple gigawatts of capacity with minimal site-specific engineering, you’re hitting ARENA’s scalability sweet spot.
If your answer is “yes” to most of these, your project could be competitive:
ARENA’s scoring isn’t just about clever technology — it’s about whether your project can make a serious dent in the cost of large-scale solar within a realistic timeframe.
From what we’ve seen in past funding rounds, the strongest applications tend to:
Where applicants go wrong:
Bottom line:
If your project can’t clearly demonstrate impact, scalability, and a realistic delivery pathway, it’s unlikely to make it past the EOI stage — no matter how clever the tech is.
You’ll need ready:
Here’s the thing about the EOI — it’s not a warm-up round.
It’s the main filter.
ARENA uses it to decide whether you’re worth the time of a full application.
If you’re not hitting the mark here, you don’t get a second chance.
And in my experience, the applicants who do well don’t just answer the question — they answer the question behind the question.
They understand what ARENA is really looking for in each scored section.
This isn’t the time to be vague. You can have the most exciting lab result in the world, but if you can’t show how it’s getting into the market — and who’s going to buy it — you’re in trouble.
You want to prove you’ve already thought about your customers, your route to market, and your partners. If you’ve got a letter of intent from a major EPC, or an MOU with a manufacturer, put it front and centre.
And don’t just say you need the grant. Explain why ARENA’s money changes the game. Something like:
“With this funding, we can accelerate market entry by three years, capturing early-mover advantage and securing export contracts before competitors.”
That’s the sort of detail that moves you up the list.
ARENA wants to back safe bets.
That means you’ve got to convince them that you, your team, and your partners can actually deliver what you’re promising.
Show them you’ve done it before — maybe not this exact tech, but something of similar scale or complexity.
Be upfront about risks, but don’t leave them hanging — every risk you identify should be followed immediately by how you’re going to manage it.
If you’ve already lined up testing facilities, suppliers, or subcontractors, name them. It signals you’re not just talking theory — you’re ready to go.
This is where you connect the dots back to their big picture — the 30-30-30 vision.
Spell out exactly how your project pushes towards:
Don’t assume they’ll do the maths in their head. If your technology could shave 5 cents per watt off the installed cost, say it. If you can add 3% to yield, say it. Put numbers to the benefit, and make it easy for them to compare you to other applicants.
If you treat your EOI like a quick admin form, you’ll be in the pile of “nice ideas, not ready yet.”
If you treat it like the first — and possibly only — chance to prove you’re a winner, you’ll be in the running.
Australian entities (businesses, universities, research agencies) at TRL 3 or above.
Any solar technology that advances efficiency, cuts costs, or improves lifetime performance in line with the streams’ focus areas.
Yes — typically dollar-for-dollar, with some flexibility for research-heavy projects.
If you’ve made it this far, you’re clearly serious about the Ultra-Low-Cost Solar PV R&D Round 4 grant.
You’re not here for general funding advice — you want to know how to actually win this grant.
So here’s the real question to ask yourself:
Do you want to work with us… or compete with us?
We live and breathe ARENA applications.
We know what their assessors like to see, the language that makes them lean in, and the types of solar projects that get through to the full application.
And we’re blunt — if your project isn’t competitive, we’ll tell you straight away rather than letting you waste months on something that won’t get funded.
This grant is competitive. Most EOIs won’t make it past the first cut.
Wouldn’t you rather go in with a team that’s written winning ARENA solar applications before — and knows how to frame your project so it scores?
You’re still reading, which tells me you’re serious.
Let’s save you the guesswork and see if your project is worth putting forward.
We don’t just check eligibility — we help you build a submission that hits the mark.
