Solar Hot Water Systems in Perth Metropolitan
Compare Perth solar hot water suppliers and installers, scored 0 to 100 on Google reviews and profile details, with what to check before you buy.
Solar hot water uses roof-mounted collectors to heat water for your home, with a storage tank and a gas or electric booster for cloudy stretches. Perth suits it well: high sunshine hours mean a properly sized system can cover most of a household's hot water demand for much of the year.
What to look for
System type: close-coupled (tank on the roof) or split (tank at ground level). Split suits shaded or heritage-style roofs.
Collector type: flat plate or evacuated tube, and how each handles Perth's summer heat.
Sizing: tank volume matched to household size, not a standard package.
Booster: gas, electric or heat pump, and the running cost of each.
Compliance and warranty: licensed plumber and electrician, certified product, and separate warranty terms for tank, collectors and labour.

Common questions about solar hot water systems
- How much does a solar hot water system cost in Perth?
- Installed prices commonly fall between about $3,000 and $7,000 depending on tank size, system type and booster. Split systems and larger tanks cost more. Rebates and small-scale technology certificates can reduce the upfront price, so ask the installer to show them as a line on the quote.
- How long does a solar hot water system last?
- Most last 10 to 15 years, and many run longer with maintenance. Tanks and anodes are the usual wear items. Check the tank warranty, which often runs 5 to 10 years, and ask when the sacrificial anode should be inspected or replaced.
- What should I expect on installation day?
- Expect one day for a straightforward replacement. The installer removes the old unit, mounts collectors and tank, connects plumbing and the booster, then tests for leaks and temperature. You will be without hot water for part of the day. You should get compliance paperwork and warranty documents afterwards.
- How can I judge the quality of an installer?
- Check their plumbing and electrical licences, ask for the exact product model and its certification, and compare warranty terms for parts and labour. Look for recent local reviews and a clear written quote with sizing reasoning, not just a package price.
