Dual Sun(DS)


DualSun aims to reduce the energy consumption of buildings by producing solar heart and electricity.

Hybrid solar allows a real synergy between photovoltaic and thermal. This hybrid installation produces two to four times more energy with the same surface. It meets the requirements of thermal regulation by reducing the need for heat while regaining profitability through the production of self-consumed electricity.

The DualSun solar panel is an advanced hybrid solar (PV-T) technology that produces simultaneously electricity (photovoltaic) and hot water (solar thermal). The patented system intelligently integrates a photovoltaic panel with a heat exchanger on the back sheet, to produce up to 3 times more energy than a traditional photovoltaic panel. In the late 2015, the Institut National de l’Energie Solaire (INES) tested the DualSun panel along with 3 major PV/T panels. The results confirmed superior performance of the DualSun technology over a wide range of operating temperature. The power increased ranges between 10% and 25%.

Another key advantage of DualSun panels is their flexibility in orientation, making them adaptable to different types of roofs. Indeed, they have dimensions and a frame of standard PV panels, so they adapt to many installation systems for framed photovoltaic panels including most roof integration systems. This is not the case for all hybrid panels. Furthermore, they are equipped with flexible hydraulic couplings with quick couplers that allow quick and easy installation, and a new patented solution to enable PV/T modules to be connected quickly from the backside (FR1781619), by dealing with the very small space at the backside. These hydraulic connections are widely tested in the solar thermal field. The DualSun engineers choose these technologies because their manufacturer has obtained the right to use the CSTBat Flexible brand, which attests to their good quality. This quick and easy installation is not the case for all hybrid panels.
