Photovoltaic Power 450W
Photothermal Power 1350W
Working Principle:
The temperature effect is an important factor restricting the power generation performance of photovoltaic systems. Taking monocrystalline silicon cells as an example, the power generation efficiency of photovoltaic modules decreases by 0.30% for every 1°C increase in operating temperature.
PVT (Photovoltaic Thermal Module) integrated photovoltaic/photothermal modules convert the received solar radiation. The short-wave part is converted into current output by the photovoltaic cells, and the long-wave part is used as the low-temperature heat source of the heat pump evaporator, enabling the comprehensive utilization of solar energy from both photovoltaic and photothermal aspects.
Technical Advantages:
Space Saving
In limited space conditions, generate electricity and provide heat simultaneously. Avoid the waste of roof resources caused by photovoltaic power generation and solar water heaters occupying roof space.
Efficiency Improvement
Photovoltaic modules have a high operating temperature under good irradiation. The heat pump circulation system can reduce the temperature of the photovoltaic module panels, thereby increasing the power generation efficiency by more than 10%.
Multi-Energy Coupling
Integration of multiple green new energy technologies such as photovoltaic, photothermal, and heat pumps, to meet the needs of electricity, hot water, heating, etc. simultaneously.
High Efficiency and Energy Saving
On the basis of air-source heat pumps, the PVT module is used as the external evaporator of the heat pump. Compared with conventional air-source heat pumps, the energy efficiency (COP) can be increased by 20-50%.
