Nowadays, many people use solar energy to generate electricity from their homes. Using photovoltaic power generation is not only clean and environmentally friendly, but also energy-saving electricity and electricity. We all know that photovoltaic power plants are high-quality, high-value, high-demand products. The correct method of use can not only ensure the power generation of the power station, but also keep it for a long time. Therefore, maintenance after the installation of the power station is particularly important.
The surface of the PV module should be kept clean. Wipe the PV module with a dry or damp soft and clean cloth. Do not wipe the PV module with corrosive solvents or hard objects. The PV module should be cleaned with an irradiance of less than 200 W/m2. It is not advisable to use a liquid cleaning component with a large temperature difference from the component.
PV modules should be inspected regularly and the PV modules should be adjusted or replaced immediately if the following problems are found. Photovoltaic modules have glass pulverization, back plate burning, and obvious color change; there are bubbles in the photovoltaic module that form a communication channel with the edge of the module or any circuit; the junction box of the photovoltaic module is deformed, twisted, cracked or burned, and the terminal is not good. contact
Regularly check the metal bracket of the solar cell array for corrosion, and regularly paint the bracket for anti-corrosion treatment. The square frame bracket should be well grounded.
During use, the photoelectric parameters and output power of the solar cell array should be checked periodically (for example, 1 to 2 months) to ensure the normal operation of the battery array.
During use, it is necessary to check the packaging and wiring joints of solar photovoltaic modules regularly (for example, 1 to 2 months). If it is found that the package is opened, the battery is discolored, and the joints are loose, off-line, corroded, etc., repair or replace them in time. .
To keep the solar photovoltaic modules square clean, such as dust, clean the wire with a clean tweezers. If the dirt cannot be cleaned, rinse with clean water and then wipe the water with a clean cloth. Never use a corrosive solvent or wipe with a hard object.
