An installer who believes in hybrid technology
Jean heard about our new DualSun hybrid technology from one of his customers. Until then, he’d only installed photovoltaic solar panels or thermal solar panels independently or side by side, but learning about a new hybrid technology made in France whetted his curiosity.
We met Jean at the Salon des ENR, which we attended in February 2013. We were able to show him the performance of our hybrid solar panel and answer his many questions about the product. Convinced by our new solar technology, he didn’t hesitate to give hybrid solar panels a try and put his trust in us.
Demonstrating the performance of hybrids to make them more widely available
Jean asserts his pioneering spirit, and it was with this in mind that he had DualSun panels installed on his roof.
What interests him more than the novelty of a solar technology is putting forward a French solution and previewing its performance, so that he can then offer it to his customers as an installer with full knowledge of the facts.
Jean has become a DualSun partner installer for his region. He can now show his installation to anyone interested in hybrid solar power.
Energy performance of the hybrid system
From a technical point of view, Jean’s roof faces south with a 20° pitch. 6 DualSun hybrid panels were installed on his roof, connected to a Clipsol balloon with 2 additional photovoltaic panels.
We carried out a simplified overlay integration on rails placed above the tiles. The installation corresponds to a CESI system, with medium-term plans to connect the system to the adjoining swimming pool. Like more and more of our customers, Jean has chosen to consume his own electricity.
Thermal performance
Jean’s circuit temperature over 3 days in August. The thermal data is extracted directly from the Clipsol control system. We can see that the water in the DualSun panels was between 50°C and 60°C, given that hot water needs are covered at 45°C. With a coverage rate of 98%, compared with the 93% predicted by the MyDualSun study, the thermal production target has been reached.
The stagnation temperature measured on this installation in midsummer is 60°C, so there’s no risk of overheating. This is due in part to the choice of roof-mounted panels, which are superimposed on the roof rather than integrated, allowing for good natural ventilation.
Photovoltaic performance
MyDualSun forecast 270 kWh of electricity production in August. With an actual production of 272 kWh, this target was also met. Real energy performance
