Our panels are built to last. There are several points that make our panels different from the other ones out there. First and foremost, as stated above, our panels are made of polypropylene, a FAR stronger and FAR longer lasting material, which is what makes our panels so suitable to the Australian Climate. Solartech Pool Heating Australia only uses top quality panels that are manufactured in the USA. Our Solar pool heating technology has come a long way in the last 20 years. Before, Rubber Matting systems were the only option. While they are cheaper they are not built to last. The rubber wears down and cockatoos attack the systems, tearing the rubber apart.
