Maintenance of photovoltaic power station to prolong the service life of the hardware and software

Many want to install photovoltaic power station early friend a big concern is that it can really use 25 years? The answer is yes. In fact, old pv power plant has been operating for more than 30 years. Photovoltaic power station to 'longevity', we need to hard and soft and repairing. Hard

many friends would like to install photovoltaic power plant is one of the biggest concerns, it really lasts 25 years? The answer is yes. In fact, the old photovoltaic power station has been running for more than 30 years. In order to 'longevity' in the photovoltaic power station, we need to hard to repair and soft repair. Hardware we know that the photovoltaic power station design life cycle generally for 25 years, mainly affected by the stent, components, and the lifetime of the inverter. First of all, the existing photovoltaic power station of the bracket is commonly galvanized steel or aluminum alloy C, the service life of the two materials are far more than 25 years. Therefore, as long as the selection of qualified scaffold products such as galvanized layer is complete, the corrosion will happen; If the thickness of the aluminum alloy stent to reach standard, don't have to worry about the service life of stents. Secondly, in terms of components, photovoltaic power station of 25 years service life depends mainly on the service life of crystalline silicon components. After 25 years of use, reliable quality of the conversion efficiency of crystalline silicon components products can still be reached the factory efficiency of 80%, but the attenuation of the thin film products will be higher, the attenuation can be more than 20% less than 25 years. As for the inverter, because they are mainly composed of electronic equipment, the service life of equipment is also very long, so the selected inverter to the quality of the product is qualified, prolong the service life is not a problem. Therefore, in order to prolong the service life of power station, we must first of all, from the perspective of the hardware: 1. Choose quality and reliable products. 2. Parts should choose monocrystalline or polycrystalline products as much as possible. Software household photovoltaic power station by components, inverter, distribution box, etc. These devices from different manufacturers. Once the equipment failure, which is unfavorable for investigation. The traditional manual testing method is time-consuming and laborious inefficient. As a result, some of the leading domestic photovoltaic pv power station operators developed monitoring system, can monitor the power anytime and anywhere, greatly enhance the overall plant operation and maintenance services, delay the aging speed of power station. Therefore, besides choosing reliable products and prolong the service life of power station, also must from the beginning of the software, choose can provide monitoring service provider in the background. Photovoltaic (pv) power plants like the human body. No matter how strong they are, at ordinary times should be kept. To ensure that the components of good performance, it is recommended that the following maintenance measures: 1. In the inverter, power distribution boxes and other outdoor electrical equipment installed on the rain cover, and regularly to cleaning and inspection of equipment, to reduce the wind and rain erosion, prolong the service life of equipment. 2, scrubbing away photovoltaic modules and check regularly. Focus on the following points: ( 1) Parts whether glass damage; ( 2) If there is a sharp objects in contact with the component surface; ( 3) Whether parts be obstacles and foreign body;
