Dual Sun(DS)


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

Briefly, the DualSun solar panel is an advanced hybrid solar (PV-T) technology that produces simultaneously electricity (photovoltaic) and hot water (solar thermal). The design of the panels has been improved by reducing thickness and weight, obtaining a faster and more reliable connection between panels and improving both electrical and thermal performance.

The hybrid solar system enables a true synergy between photovoltaic and thermal energy. This hybrid system produces two to four times more energy with the same surface area. It meets the requirements of thermal regulation by reducing the demand for heat while becoming profitable again through the production of self-consumed electricity.

The patented system intelligently integrates a photovoltaic panel with a heat exchanger on the back to generate up to three times more energy than a conventional photovoltaic panel. At the end of 2015, the Institut National de l’Energie Solaire tested the DualSun panel together with three large PV/T panels. The results confirmed the superior performance of DualSun technology over a wide operating temperature range. The increase in performance is between 10% and 25%.

Another key advantage of DualSun panels is their flexibility in orientation, which allows them to be adapted to different roof types. Because they’ve the dimensions and frame of standard PV panels, they fit many framed PV panel installation systems, including most roof integration systems. This is not the case with all hybrid panels. In addition, they’re equipped with flexible hydraulic connections with quick couplings for quick and easy installation. Moreover, there is as a new patented solution that allows PV/T modules to be connected quickly from the back by using the very small space. These hydraulic connections have been tried and tested many times in the solar thermal sector.

DualSun engineers have chosen these technologies because their manufacturer has obtained the right to use the CSTBat Flexible brand, which speaks for their good quality.
