Len 50 Wp solar module specifications. Temperature and efficiency of the solar cell. Temperature and efficiency of the solar cell with a 10-fin heat sink.
The accumulated heat is dissipated by forced air movement (using air intake fans) on the surface of PV panels that use air as a cooling fluid. Cooling fluids such as water or nanofluids absorb the heat accumulated in the system and transfer it away through a circulation system.
A part of the incident solar radiation on the solar cell produces an increase in its temperature and reduces the PV panel efficiency because the materials used for PV cells are sensitive to temperature and may cause permanent structural damage to the cell if the high temperature remains for a more extended period .
To give a general idea: A typical crystalline silicon solar panel might lose 0.3% to 0.5% of its efficiency for every 1°C increase in temperature above 25°C. On a hot summer day where panel temperatures might reach 60°C (140°F), this could translate to a 10-15% decrease in power output compared to the panel’s rated efficiency.
Many natural factors help dissipate the heat from a solar panel, like convection or conduction losses, but if the solar panel is specifically designed to create these convection and conduction phenomena, it can provide better efficiency. Based on this previous conception, some devices are designed for absorbing solar radiation.
Solar Irradiance: More intense sunlight leads to higher panel temperatures. Under full sun conditions, panel temperatures can easily reach 50-65°C. Wind Speed: Wind can help cool panels, potentially improving efficiency. Studies have shown that wind speeds of 1 m/s can reduce panel temperature by 5-11°C.
