How to maintenance and maintenance of solar photovoltaic components?

Now many people home electricity will choose solar photovoltaic power generation, use of photovoltaic power generation not only clean and environmental protection, energy-saving electricity, also can sell electricity to make money. We all know photovoltaic power station is high quality, high value, high demand of product, the right using method is not only the

at present, many people in the home electricity when choose solar photovoltaic power generation. Photovoltaic power generation is not only clean environmental protection, but also can sell electricity to save energy and money. As is known to all, photovoltaic power station is a kind of high quality, high value, high requirement of products. Correct usage can not only ensure the plant power generation, and can guarantee long life of power station. Therefore, power plant maintenance after installation is particularly important. 1. The surface of the pv modules should be kept clean. Should be used dry or wet soft cloth to wipe clean photovoltaic modules. It is forbidden to use corrosive solvent wipe the photovoltaic modules or hard objects. Photovoltaic modules should be less than 200 watts / ㎡ in irradiance under the condition of cleaning, and shall not be used with the component temperature larger liquid cleaning components. 2. Photovoltaic modules should be check regularly. If it is found that the following questions, should immediately adjust or change of photovoltaic modules. Photovoltaic modules to shatter and burned in the back color is obvious. On the edge of the existed in the pv module and the module or any circuit form bubbles connected channels; Photovoltaic modules junction box deformation, distortion and rupture or burns, terminals can not good contact. 3. Photovoltaic components of charged warning signs should not be lost. 4, photovoltaic modules using metal framework, the framework and good stent should be combined, the contact resistance between the two is not greater than 4 omega, framework must be firmly grounded. 5. In the absence of shadows under the working conditions in the solar irradiance is 500 watts per square meter or more than, less than 2 m/s wind speed conditions, the same external surface of the photovoltaic modules ( Battery is directly above area) The temperature difference should be less than 20 ℃. Installed capacity of more than 50 kilowatts per hour of photovoltaic power station should be equipped with infrared thermal imaging detection photovoltaic components the surface temperature difference. 6. In the solar radiation intensity is basically the same, the deviation is less than 5% of cases, measured with DC clip-on ammeter connected to the same DC female head of each photovoltaic modules list of input current. 7. Shows all of the bolts, weld and connection should be solid and reliable, and surface coating shall not crack or fall off, otherwise may not be timely brush. 9. With automatic tracking system of the polar axis on the solar cell phalanx bracket, check the electrical and mechanical performance of tracking system is normal. 10, regularly check the solar cell corrosion situation of square metal stents, and regularly to paint anticorrosion treatment support. Square brackets were good. 11. In use process, should be regularly ( For example, 1 ~ 2 months) Test the photoelectric parameters of solar array and output power, to ensure the normal operation of arrays. 12, in use regularly ( Such as 1 ~ 2 months) Check the solar energy photovoltaic component packaging and wiring connector, if found to have packaging glue water, battery discoloration and loose connection, offline, corrosion, and so on and so forth. , timely repair or replacement. 13 square lighting surface clean, to keep the solar photovoltaic components, such as dust, usable and clean line filter for cleaning. If dirt does not clear, please rinse with water, then dry with a clean cloth water mark. Do not use corrosive solvent to clean or wipe with hard objects. Clean up the snow in a timely manner.
