21 Dualsun panels on a house - Colomiers (FR)

  • 2015
  • Colomiers, France
  • Power output : 5,25kWc + 1,5Wth
  • Panels : 4 hybrid + 17 photovoltaic

Mr. Destreez was looking for an efficient, aesthetic solar solution that would also qualify for the CITE tax credit to renovate his house, which was built in the 1970s. He moved in with his wife and daughter in 2011. A major renovation project was then required to improve the comfort of the house and keep electricity consumption and bills under control.

The installation is technically a great success, thanks to a DualSun-approved craftsman we put him in touch with, who installed 4 hybrid solar panels and 17 photovoltaic panels.

“The panel installer was a major asset, and a real relationship of trust was established. Mr. Destreez

To renovate his house, he had to redo the windows, change the boiler, insulate from the outside and modernize the whole. This project manager wanted to take advantage of the prices associated with the resale of electricity before they continued to fall too much. He confided to us that buying a solar installation was a good investment and a good gesture in favor of the environment.

“In France, electricity is supposed to be clean, apart from waste treatment, which is a problem with nuclear power. Today, in terms of recycling, solar energy is globally beneficial, and what’s more, DualSun panels are French products.” Mr. Destreez

Indeed, to produce his own electricity, thanks to this type of solar installation, there is less demand for coal and nuclear power, he told us. However, Mr. Destreez is not anti-nuclear!

“I have good south-west exposure in Toulouse, so it’s good to take advantage of it, because the sun is a clean and inexhaustible energy. When you have a nice roof surface and the financial capacity, it’s a shame not to do it. I like the DualSun concept, I think it’s great and much nicer than other systems. My criteria for choosing DualSun also included aesthetics. I find that a single rectangular field of identical panels is prettier than a patchwork of panels of different brands positioned in different places and not necessarily in the same direction”. M. Destreez
