The following describes the main inspection and maintenance of each part of the photovoltaic power generation system.
Solar photovoltaic array inspection and maintenance
(1) To keep the solar cell module square array lighting surface clean, such as dust, can be cleaned with a clean line duster.
If there is dirt can not be cleaned, clean water can be used, and then dry the water mark with a clean rag. Do not clean with corrosive solvents or wipe with hard objects.
(2) In case of heavy rain, hail, snow and other circumstances, although the solar array will not be damaged, but should be dealt with the battery pack clean and wipe the surface of the parts in time. When there is snow, it should be cleaned up in time.
(3) To regularly check whether the metal bracket of solar photovoltaic square array is corroded, and regularly paint the bracket as if processing. Square brackets should be well grounded.
(4) Photoelectric parameters and output power of solar cell array should be tested regularly (such as 1 to 2 months) during use. To ensure the normal operation of the photovoltaic array.
(5) During use, the package and connecting wire of solar cell module should be checked regularly (such as 1~2 months), if any package is found water, battery discoloration and street loosening, off-line, corrosion and other phenomena, should be repaired or replaced in time.
(6) For the solar cell square array bracket with pole axis automatic tracking system, the mechanical and electrical of the tracking system should be checked regularly check whether the performance is normal.
(7) In use, it is necessary to check periodically (such as 1~2 months) whether the electrical components in the DC bus box are loose or off line.corrosion and other phenomena. In the thunderstorm season, special attention should be paid to whether the lightning arrester module in the bus box is invalid. If it is invalid, it should be replaced in time.
(8) Regularly check the growth of plants around Founder to see whether the photovoltaic array is blocked, and clean it in time.
