The Eco-ConScious Choice
Harness the Sun's Power
There’s no better place than Darwin to make the most of solar energy. With Harwood Plumbing & Gasfitting’s professional solar hot water services in Darwin, you can enjoy reliable, eco-friendly hot water while cutting down on electricity costs.
Solar systems use rooftop panels to capture energy from the sun, transferring it to heat water stored in an insulated tank. It’s a simple, efficient process that reduces reliance on traditional power sources — and with Darwin’s high sunshine hours, you’ll get excellent year-round performance.
Whether you’re replacing an old electric unit, building a new home or looking to lower your environmental footprint, a solar hot water system offers long-term value. Call (08) 8984 4008 today to find out how much you could save with a solar hot water installation in Darwin.

Savings & Sustainability
Built for Darwin's Climate
Darwin’s tropical weather makes it the perfect region for solar hot water systems. With consistent sunlight and high daytime temperatures, solar panels can efficiently heat large volumes of water with minimal energy input. This means households and businesses can reduce electricity usage by up to 80%, depending on system size and configuration.
Modern solar systems use either flat-plate collectors or evacuated tube collectors to absorb heat. Flat-plate systems are ideal for most homes, while evacuated tubes offer higher efficiency in shaded or cooler conditions. A qualified installer will assess your roof orientation, water usage and budget to recommend the best setup for your property.
While solar hot water systems have a higher upfront cost than electric or gas models, the long-term savings easily outweigh the investment. Reduced power bills, government rebates and a lower carbon footprint make solar an appealing choice for eco-conscious homeowners.
FAQ
Everything You Need To Know
How does a solar hot water system work?
Solar hot water systems use rooftop panels (collectors) to absorb energy from the sun. This energy heats water that circulates through the panels and into a storage tank. When sunlight is limited, an electric or gas booster automatically kicks in to maintain consistent water temperature, ensuring you always have hot water available.
How much can I save with a solar hot water system?
Savings vary depending on your household’s hot water usage, but most homes can reduce water heating costs by 60–80%. Since water heating often accounts for a third of total household energy use, switching to solar can significantly lower your power bill and carbon footprint.
Do solar hot water systems work on cloudy days?
Yes. Most systems include a gas or electric booster that automatically heats water when sunlight isn’t sufficient. This ensures you’ll have a consistent hot water supply regardless of weather conditions. Boosters are energy-efficient and activate only when needed, minimising additional running costs.
