The impact of environmental factors on the performance of photovoltaic modules of photovoltaic power ptation

Temperature: The operating temperature of the photovoltaic module of photovoltaic power ptation is one of the main factors affecting its performance. Generally speaking, the efficiency of photovoltaic modules decreases as temperature increases. This is because at high temperatures, the electron mobility of semiconductor materials increases, causing the resistance inside the component to increase, thereby reducing the output voltage and current. For every 1°C increase in temperature, the output power of photovoltaic modules may decrease by 0.4% to 0.5%. Therefore, the power generation of photovoltaic power plants under high-temperature climate conditions may be lower than expected, affecting their economic benefits.
Irradiance: Solar irradiance directly affects the power generation capacity of photovoltaic modules. Under high irradiance, photovoltaic modules can generate more electricity. However, irradiance is not constant and is affected by factors such as seasonal changes, sunshine hours, and cloud cover. For example, under cloudy or cloudy conditions, the irradiance is significantly reduced, and the power generation of photovoltaic modules will also be significantly reduced. Photovoltaic power plants need to be optimally designed based on local irradiance conditions to maximize power generation.
Humidity and rainfall: High humidity and frequent rainfall can increase contaminants on the surface of photovoltaic modules, such as dust, dirt, and moss. These pollutants will block sunlight and reduce the light entering the component, resulting in a decrease in photoelectric conversion efficiency. Moisture penetrating into components can cause electrical shorts and reduce system reliability. 
Wind speed and direction: Changes in wind speed and direction may have an impact on the mechanical structure and installation angle of photovoltaic modules. Strong winds may cause damage to the module support structure or offset the module, thereby affecting the overall performance of the photovoltaic power station. Reasonable structural design and installation methods can effectively resist the influence of wind and ensure the stability of components.
