Stop Wasting Your Solar Energy
Your panels make most of their power between 9am and 3pm. But your home needs energy most at dawn and dusk - when the sun's gone.
So you export cheap solar by day, then buy expensive grid power at peak. With feed-in tariffs near zero and "sun taxes" coming, that exported solar has gone from a credit to a cost.
Solar Export Prices Have Declined and are Soon to be Taxed...
Meanwhile Grid Electricity Prices Continue to Rise

Batteries are Expensive and Risky
Home batteries cost $8,000–15,000, degrade within a decade, and carry fire risk. Thermal Dawn stores your solar as heating, cooling, and hot water for a fraction of the cost, no degradation, no fire risk, and made in Australia.
Fossil Fuels Keep Getting More Expensive
Every time you heat or cool at dawn or dusk, you're paying premium rates for fossil-fuel power. Thermal Dawn shifts that demand to your own solar hours, cutting bills and emissions while you stay comfortable year-round.
How Thermal Storage Works
Heating, cooling, and hot water are 60% of your home's energy use, and most of it hits at peak times when power costs the most.
Thermal Dawn captures your abundant morning solar and stores it as heating, cooling, and hot water for when you actually need it: dawn, dusk, and through the night.
It's no longer an idea. It's on a home in Melbourne.
Our first home is live in Hawthorn, gas boiler gone, gas meter off the house, heating now running on stored solar. Here's week one, straight from the customer's own app.

Early single-week readings from the customer's own app, while we're still tuning the system. Sustained, that pace is around `[ANNUALISED, ~$3,000]` and `[ANNUALISED CO₂, ~2.9 tonnes]` a year. Your home's number is confirmed at your free site assessment, not a brochure figure.
"We've been looking for 5 years for a hydronic heat pump, but we didn't want to pay $25,000. We finally did it."

Why we're building this
Thermal Dawn was selected for Startmate's 2026 cohort. Here's our founder making the case, to a room of investors and operators, for why Australian homes need thermal storage, not another imported battery.
Designed for Australian conditions, built from Australian materials, and retrofittable to most homes. No degrading batteries, no imported lithium.
About us
At Thermal Dawn, we're building the infrastructure Australia needs to shift from imported lithium batteries to sovereign thermal systems that balance our grid, starting with your home. Our thermal batteries solve the problem imported lithium can't: capturing abundant dawn solar and storing it as heating, cooling, and hot water for the peak-demand hours when grid power costs the most.
Our systems are designed, built, and assembled in Australia, at our own production facility in Hornsby, New South Wales, from Australian materials, and built to last decades, not the few years before a lithium battery degrades. Thermal Dawn is supported by Cicada Innovations and the NSW Office of the Chief Scientist and Engineer, backed by an Investment NSW grant, and a member of the Startmate accelerator. This isn't imported technology we're reselling. It's the thermal infrastructure Australia needs, engineered by Australians who live here.
