DualSun - A hybrid solar panel that generates electricity and hot water simultaneously

DualSun aims to reduce the energy consumption of buildings by generating clean and affordable solar heat and electricity.

DualSun developed a hybrid solar panel certified in the world that generates simultaneously electricity and hot water. A regular photovoltaic panel converts only 20% of the sun’s energy into electricity while the remaining 80% is lost as heat. This hybrid panel captures this heat and transfers it to produce hot water. With zero risk of overheating and by optimizing rooftop space, the DualSun hybrid panel is a technology for all types of buildings and applications: hot water production, pool heating, and space heating by coupling with heat pumps and/or geothermal units.
