　　How to clean dust from photovoltaic cells and what are their application areas?

　　1. Tips for cleaning dust from photovoltaic cells

　　1. Under normal circumstances, photovoltaic equipment should be inspected every four years. First, all photovoltaic fans should be replaced. Then, according to the operating conditions, professionals should check the ripple condition of the DC circuit and check the appearance of the DC capacitors and AC capacitors. If there is no abnormality, use a special meter to test the capacitor capacity to determine whether to replace the capacitor.

　　2. The cleaning method is to start reinstalling the plug-in after the cleaning and maintenance are completed. Pay attention to the plug-in being inserted tightly and the secondary plug being plugged in properly. Check whether there is resonance between the fan and cover after power is turned on.

　　3. If the above conditions are normal, the photovoltaic power supply will continue to manually bypass the power supply load. When there is no load, professional technicians will individually debug the automatic bypass, rectifier and inverter for the photovoltaic power supply.

　　4. If the debugging is normal, the photovoltaic starts to switch from manual bypass to automatic bypass and then to the inverter for power supply.

　　5. Secondly, during dust removal, check whether the connectors and plug-ins are loose or not in firm contact.

　　2. Application fields of photovoltaic cells

　　1. User solar power supply

　　Small power supplies ranging from 10-100W are used in remote areas without electricity, such as plateaus, islands, pastoral areas, border posts and other military and civilian life needs, such as lighting, TVs, radios, etc.

　　2. Transportation field

　　Such as navigation beacon lights, traffic/railway signal lights, traffic warning/sign lights, street lights, high-altitude obstacle lights, highway/railway wireless phone booths, unattended road shift power supply, etc.

　　3. Communication/communication field

　　Solar unattended microwave relay station, optical cable maintenance station, broadcast/communication/paging power supply system; rural carrier telephone photovoltaic system, small communication machine, soldier GPS power supply, etc.

　　4. Petroleum, ocean, and meteorological fields

　　Petroleum pipelines and reservoir gate cathodic protection solar power systems, oil drilling platform life and emergency power supplies, ocean detection equipment, meteorological/hydrological observation equipment, etc.

　　5. Home lighting power supply

　　Such as garden lights, street lights, portable lights, camping lights, mountain climbing lights, fishing lights, black light lights, rubber tapping lights, energy-saving lamps, etc.

　　6. Photovoltaic power station

　　10KW-50MW independent photovoltaic power stations, wind and solar (diesel) complementary power stations, various large parking plant charging stations, etc.
