The maintenance and maintenance of photovoltaic carport mainly includes the following aspects:
1.Regular inspection: Conduct a comprehensive inspection of the PV carport every three to six months, including cleaning the surface of the module, checking the junction box and cable connections, fastening screws, protective covers, etc., and doing necessary maintenance and adjustments. During annual maintenance, PV modules should be inspected for performance degradation, dirt should be removed, cables and connectors should be checked for wear and tear, inverters and battery systems should be inspected, etc. In addition, the support structure of the photovoltaic carport should be checked regularly to ensure its integrity and stability.
2.Cleaning and maintenance: Clean the surface of the PV module regularly to remove dust and dirt to maintain its good heat dissipation and ventilation effect. When cleaning, you can use a soft brush or high-pressure water spray gun, but follow the manufacturer's recommendations and avoid using chemical cleaners or sharp tools.
3.Waterproof and moisture-proof: Pay attention to waterproof and moisture-proof work, especially in rainy season or humid areas, to ensure that the sealing and waterproof performance of the photovoltaic carport is good. Regularly inspect the waterproof layer, and repair or replace it in time if it is damaged or aged.
4.Lightning protection and grounding: If the photovoltaic carport is installed with a lightning protection grounding system, it is necessary to regularly check whether its grounding resistance value meets the requirements to ensure the effectiveness of the lightning protection and grounding system.
5.Consider environmental factors: take appropriate protective measures according to the climate and environmental conditions where the PV carport is located. For example, in desert areas, it may be necessary to clean up sand and dust frequently; In cold regions, the impact of snow cover on PV modules may need to be considered.
6.In addition, it is recommended to follow the guidance in the manufacturer's use and maintenance manual, and communicate regularly with relevant technicians for more specific and accurate service recommendations. In case of abnormal situations (such as weather disasters, equipment failures, etc.), overhaul and maintenance should be carried out immediately to ensure the safety and normal operation of the photovoltaic carport.
