Product Introduction
PVT panels (Photovoltaic-Thermal panels) are an innovative product that combines photovoltaic power generation with solar thermal collection technology. Their core principle is to achieve efficient utilization of solar energy through synergistic operation.
Working Principle
Our active photovoltaic-thermal (PVT) system features an innovative design, with its thermal module (T-module) utilizing Freon as the heat transfer medium. Thanks to Freon's evaporation temperature as low as -40°C, this medium not only efficiently absorbs waste heat generated during photovoltaic panel operation but also actively extracts heat from the surrounding environment. Through a dual-effect heat absorption mechanism, this heat is transferred to the air-source heat pump, significantly enhancing the heat pump's heating efficiency and achieving a doubling of energy efficiency.
By operating the air-source heat pump around the clock, the system can stably provide 24-hour uninterrupted heating or hot water services. Simultaneously, the photovoltaic panels supply clean electricity to the heat pump, forming a synergistic "light-electricity-heat" cycle that achieves zero carbon emissions. This perfectly meets users' dual demands for electricity and thermal energy, creating an efficient and eco-friendly energy solution.
A PVT panel consists of two main modules:
PV Module: The photovoltaic power generation module, which converts solar energy into electricity through photovoltaic cells.
T Module: The thermal recovery module, located beneath the photovoltaic panel. It uses a heat pump working fluid (refrigerant) to transfer waste heat generated during photovoltaic operation and heat from the surrounding air, acting as an external evaporator for the heat pump to produce hot water or heating.
This design not only lowers the temperature of the photovoltaic panel (by about 25°C), improving power generation efficiency, but also enhances overall solar energy utilization. It converts otherwise wasted thermal energy into usable energy, achieving a comprehensive solar energy utilization rate of over 80%.
Main features
Technical Advantages
Space saving：Achieve both functions of power generation and heating within a limited space. Avoid mutual encroachment of roof space by PV power generation and solar water heater and causing waste of roof resource.
Improving efficiency of photovoltaic power generation：Since the operating temperature of PV modules under good irradiation is much higher and the heat pump circulation system can lower the temperature of the PV module panels, thus improving the power generation efficiency by 10%-18%.
Multi-energy coupling：PV/thermal/ASHP is integrated with multiple green and new energy technologies to meet the need of electric power, hot water, heating and
so on.
Energy efficient：On the basis of ASHP, the PVT module is used as an external evaporator of the heat pump. Compared with conventional ASHPs, the energy
efficiency is improved by 20%-50%.
