Distributed photovoltaic power station now is no longer a new thing, more and more enterprises and residents have begun to install photovoltaic power station. In order to make the operation of the photovoltaic power generation systems to maintain security, economic and reasonable, the owner in use for a long time how to correct maintenance,
distributed photovoltaic power station is now is nothing new, more and more enterprises and individuals have started to install photovoltaic power station. In order to make the photovoltaic system operation and maintenance of security, economic and reasonable, in the process of long-term use, the owner should how to proper maintenance and photovoltaic power generation equipment maintenance? First of all, appearance inspection, please check carefully whether the parts have cosmetic defects. Focus on the following: a) Parts whether glass damage; Sharp objects whether contact component surface; c) Whether parts be obstacles and foreign body; d) If there is a corrosion battery grid line. This kind of corrosion is due to installation or transport packaging material components surface damage caused in the process of water vapor penetration into components. e) If there is a burning through trace observation components on the back. f) Check parts and support between the fixed screw loose or damaged, and timely adjustment or repair. Second, clean solar power system, the key need to pay attention to the following: a) Parts surface accumulation of dust or dirt will reduce capacity, should as far as possible a regular cleaning every year ( Specific time interval depends on the conditions of the installation site) 。 Clean with a soft cloth, dry or wet. Do not recommend using mineral water cleaning, lest leave dirt on the glass surface. b) In any case, shall not use the rough surface of the material to clean the parts. c) In order to reduce the potential of electric shock or burns, jing ke Suggestions in the light of the early in the morning or in the evening not too strong and module at a lower temperature clean pv modules, especially in the high temperature area. d) Don't try to use glass or exposed wires clean photovoltaic module, otherwise there will be a risk of electric shock. Three, connectors and cable inspection, it is suggested that for once every six months the following preventive maintenance a) Check the junction box of the sealant, make sure there are no cracks or cracks. b) Check the pv modules for the signs of ageing. Including possible rodent damage, climate ageing and all connectors are closely connected and corrosion. Check whether the parts is good grounding. Photovoltaic (pv) power plant long exposure in the open air environment, without any protection. Natural environment factors had a great influence on power plants, directly affect the service life of the photovoltaic power station and power generation efficiency. To improve the utilization efficiency of photovoltaic power station, maintenance is very necessary. Routine maintenance is not complicated. Photovoltaic power station component cleaning and inspection on a regular basis, and should be carried out when the sun is weak clean. Photovoltaic panels cannot be trampled, need insulation shoes and helmets. In short, in the photovoltaic power plant design and operation of the entire life cycle, to control the key risk, thereby reducing electricity costs, improve the return on investment.
