In summer, dust, bird droppings and other dirt are easy to adhere to the photovoltaic modules. These shelters not only affect the power generation, but also cause the hot spot effect of the modules, especially in summer. Therefore, it is necessary to do a good job in the daily inspection and maintenance of the power station on a regular basis, pay attention to cleaning and cleaning the shelters on the power station, and keep the components in a state of ventilation and heat dissipation at all times.

Under direct sunlight in summer, the internal temperature of the inverter, which is the core component of a photovoltaic power station, may reach more than 80 degrees. If there is no good heat dissipation and ventilation, high temperature will not only cause the derating output of the inverter, but also accelerate the aging of the internal components of the inverter, which is prone to failure.

For this reason, the high-temperature sun protection work of the photovoltaic inverter must be in place! For example, place the inverter in a cool place that avoids direct sunlight, such as the back of the module or under the eaves. Or add a cover plate to the inverter to ensure sufficient ventilation and heat dissipation of the inverter. In addition, direct sunlight on the cables will also cause aging of the cable insulation and affect the safe operation of the power station. Regular inspection and maintenance are also required.

In the hot summer, many users will continuously sprinkle water on the surface of photovoltaic modules in order to cool down their own photovoltaic power plants. Although the temperature of the modules is lowered to a certain extent, they do not know that there will be certain safety hazards. If the insulation and grounding of your power station are not protected against water during design and installation, there may be a risk of electric shock. In addition, sprinkling water to cool down is equivalent to a "sun rain", which will also reduce the power generation of the power station.
