Recently, the first round of typhoon this year-Typhoon No. 2 "Parrot" was generated in the South my country Sea, with a landing intensity of tropical storm level or severe tropical storm level, and brought heavy rainfall weather, which is more destructive. Photovoltaic power plants are either built in the wild or on the roof, facing great uncertainty. When extreme weather such as typhoons comes, we must make every preparation.
1 Before the typhoon crosses, timely and comprehensively inspect the installation of the photovoltaic power plant, including whether the screw fasteners and fasteners are fastened firmly, check whether there is any looseness in the middle and side pressure blocks of the photovoltaic power plant, and timely Tighten.
2 For photovoltaic power plants installed with hooks and fixtures, check whether the hooks and fixtures are firmly installed. For photovoltaic power plants installed on flat roofs, the tandem components on the windward side can be bound and fixed with double strands of 2 square millimeters of iron wire. For a power station with a small fixed pier, the weight of the power station can be increased with sandbags.
3 For photovoltaic power stations without protective brackets, install and fasten the windproof tie rods to prevent the photovoltaic brackets from twisting with the wind; ground power plants should tamping the ground anchors on both sides of the array.
4 Check the insulation and tightness of each electrical equipment of the photovoltaic power station, and check whether the AC and DC terminals are connected properly. If the ground photovoltaic power station encounters low terrain, high water level, and bubbling water in the combiner box, the grid-connected inverter should be detached from the site as much as possible or re-selected for high ground.
5 When ascending to check the power station, please pay attention to personal safety during the operation. The electrical inspection should be carried out by qualified professionals with electricity. Do not touch the live parts of high voltage (DC, AC) at will. Please do not work outdoors when a typhoon crosses the border.
What should I do after a typhoon?
1. First check the electrical box, you need to pay special attention to whether there is any problem with the surge protector.
2. Then check whether the solar panel is damaged. If it is found to be damaged, it is necessary to do a physical examination of the entire power station to prevent the cracked components from affecting the safe and stable power generation of the entire system.
3. Clean up the sundries on the photovoltaic panel to prevent the shielding from affecting the power generation of the photovoltaic system.
