About Us

PowerOptimal, founded in 2014, is a leader in sustainable, smart, simple energy solutions, specialising in hot water. Our technology platform is built on proven South African electricity demand management technology, with a strong track record of successful installations over more than 10 years.

Our intellectual property and manufacturing are proudly South African. Our engineers bring over 60 years’ combined experience in light current electrical design and manufacturing.

We have two main product ranges:

Our Elon® solar PV water heating solution allows for direct connection of solar PV (photovoltaic) panels to standard electric water heaters (geysers). Using our proprietary direct current (DC) switching technology, water heating using solar PV is now cost-competitive with solar water heaters and heat pump systems and with much longer lifetimes and minimal maintenance.

PowerGuard® is a demand management solution that can reduce your peak power demand by up to 50%, and reduce your electricity bill by up to 20%.

With our proven technology, track record of successful installations and experienced team we can help you save money and manage your electricity supply limitations whilst reducing your carbon footprint.
