How do photovoltaic panels affect the weather?
Hu et al. studied the temperature changes after installing photovoltaic arrays in major desert areas around the world by the weather research and forecasting model simulations, and the results showed that the temperature decreases 2 °C with the absorption of solar radiation by the panel in the main desert area [ 17].
Why are solar panels sensitive to temperature changes?
When sunlight strikes a solar panel, it generates direct current (DC) electricity through the photovoltaic (PV) effect. However, solar cells are sensitive to temperature changes, and this sensitivity is primarily attributed to two key factors: the temperature coefficient of voltage and the temperature coefficient of power.
