Photovoltaic-thermal PVT hybrid solar has the potential to play a major role in the renewable energy sector. This technology is ideally suited for buildings because it provides a significant amount of solar heat with the same dedicated photovoltaic area, especially pertinent for designing positive energy buildings. A study comparing different solar technologies for positive energy buildings was conducted by the independent engineering company TRIBU ENERGIE, and shows that for a 5-floor building in the south of France, a PVT system is the cheapest solution to obtain the E+/C- French label for positive energy buildings, and the most optimized in terms of roof area required. More and more buildings are equipped with this solution, like the KTR France headquarters in Lyon, France with a 2SOL system that couples PVT modules with a geothermal heat pump. A system composed of 25 DualSun modules (40m²) and a 200m deep double U probe ensures the 6000L hot water needs of the building for heating, cooling and domestic water via a water-to-water heat pump. The annual performance of the PVT installation simulated with PolySun is 18MWh of thermal production ensuring 46% of hot needs in addition to 15MWh of photovoltaic production.
