Heating water is the second-largest energy cost in the average Australian home. A high-efficiency evacuated tube solar hot water system can supply up to 90% of that demand straight from the sun — even on cold, overcast days.
Why evacuated tubes
Each vacuum-sealed tube acts like a thermos, capturing solar energy while minimising heat loss. That makes them highly effective in low ambient temperatures and diffuse light, where flat-plate collectors struggle. A boosted backup ensures you never run out of hot water.
The rebate maths
Most SolarArk solar hot water systems qualify for Small-scale Technology Certificates (STCs) under the federal Renewable Energy Target, plus various state-based incentives. These can substantially reduce the up-front cost.
The exact number of STCs depends on your system and postcode zone. Our team calculates your precise rebate — and models your return on investment — before you commit.
