Smart solar for smart buildings: a powerful hybrid solar panel 100% Made in France that generates 3x more energy.

Buildings represent 30% of total energy consumption in the world – which presents not only a major environmental risk but an economic one too. DualSun aims to meet these challenges and reduce the energy consumption of buildings by proposing a competitive and local solar solution that provides our daily energy needs: electricity and hot water. DualSun has developed an advanced hybrid solar (PV/T) panel that produces simultaneously electricity (photovoltaic) and hot water (solar thermal) for homes and buildings. The patented system intelligently integrates a photovoltaic panel with a heat exchanger on the backsheet, to produce 3 times more energy than a traditional photovoltaic panel. The DualSun solution is designed to transform our homes and offices into positive-energy buildings.
