Winter and spring how to clean the roof of the photovoltaic power station?

One, pay attention to the photovoltaic power station precipitation time, should try to avoid the photovoltaic power station work time. Under high temperature and strong light, the photovoltaic power station of high voltage, high current, may cause the damage of components or even endanger the cleaning personnel, so the

first, pay attention to the timing of the photovoltaic power plant dust dust removal, should as far as possible the best working time to avoid photovoltaic power station. Under high temperature and strong light, the photovoltaic power station with high voltage and large current, which may lead to damaged, even endanger the cleaner. Therefore, Morgan risheng suggest that everyone choose cleaning in the morning or evening. In the meantime, photovoltaic power station of low working efficiency, low power, thus reducing the risk of clean. Photovoltaic components at the same time, it is recommended to use a soft brush to clean the surface of the glass, clean water, and use the smaller force, in order to avoid damage the glass surface. Second, pay attention to the safety of the equipment maintenance 1, pay attention to the safety of photovoltaic equipment. Photovoltaic power station is supported by many bracket, cable and screws and fixed. When clean parts, not to disrupt the balance should be paid attention to and protect a stent. You can check with frequency converter, control box, such as equipment is running normally, wiring whether firm, is damaged. In particular, you should check the inverter of the fan is working correctly. 2. Pay particular attention to components of security. In order to eliminate the hidden danger of leakage, clean with a soft cloth before cleaning parts, then wipe away parts floating on the surface of water droplets, to ensure the safety of the parts in the cleaning process. 3. Its security is very important. Since most household photovoltaic system installed on the sloping roof, when cleaning should pay special attention to pedal empty or sliding, scratches, and the risk of falling. Three, cleaning must have a certain amount of time, for example, in northern China, haze is serious, traffic developed, many cars led residential photovoltaic power plant dust accumulation. Usually, the dust cleaning once a week. If you have bad weather, it will change accordingly, clean frequency will be increased. Four, direct flush must pay attention to the temperature and location in the cold winter, when clean photovoltaic modules should avoid direct water to clean. If the temperature is too low, shortly after the water washing, component surface can form a layer of ice, which may result in the crack of the component. The weather is good, it can be used cleanly. In addition, in the process of water to clean, must also prevent water directly into the components of the backboard, wet connector and terminal, and to prevent leakage.
