From France
Maturity stage TRL 9 / CRI 3-4 - Commercial Scale Up / Multiple commercial Applications

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.

The Environmental Benefits

  • The panels can be recycled up to 95% and has an average lifetime of 30 years.

The Financial Benefits

  • Payback in 8 to 10 years
  • Over 18,400 dollars in savings over the lifetime of the installation (almost double of an equivalent PV installation)
