A brilliant past and an even brighter future!

In 1953, SW Hart and Co., a pioneering plumbing company based in Perth, decided that the sun was the best energy source to heat water in Western Australian homes. As a result, solar hot water in Australia was born and Solahart geared up for expansion. Since then we’ve built a reputation as a world leader in solar innovation and technology and invested millions of dollars into R&D and manufacturing. We’ve also installed over one million systems in over 70 countries around the world. We’re at Everest Base Camp and Antarctica. Even Nelson Mandela’s South African home had a Solahart system installed on the roof. Today, after more than 60 years as Australia’s free energy experts, we’re set to turn our brilliant past into an even brighter future.
