Solar energy utilization is mainly divided into two aspects: photovoltaic and solar thermal.
Photovoltaic utilization refers to the way of generating electricity that uses solar radiation to directly transform into electrical energy. The system is formed through technical equipment such as power generation, power storage, inverter, boost, and power transmission. There are two modes of off-grid and grid-connected.
Solar thermal utilization is collectively referred to as solar thermal utilization, which includes solar water heating, solar cookers, solar heating, and solar thermal power generation.
PVT is to integrate the two technologies of photovoltaic and solar thermal with the two industries to achieve the result of complementary advantages and 1+1>2.
Photovoltaic-thermal (abbreviated as PVT) was first proposed by scientists Kerm and Russell in 1978.
The power generation efficiency of crystalline silicon solar cells depends on their operating temperature, and a 1°C increase in temperature will reduce the output power by 0.4% to 0.5%. Since more than 80% of the energy reaching the surface of the battery is converted into heat, the operating temperature of the solar cell is usually above 50 ℃, even reaching 80 ℃ when the heat dissipation is poor, so this will seriously affect the working efficiency of the solar cell.
In view of the inherent characteristics of photovoltaic cell modules that reduce their photoelectric conversion efficiency due to the increase in temperature, measures to improve the total utilization rate of solar energy by removing the heat of the module and converting it into useful heat energy.
As an influential company in the photovoltaic industry, ENSUN SOLAR has continued to invest in PVT research and development for many years, and has accumulated a large amount of data and experience, which will surely promote the development of the PVT industry to a higher level.
