Wind protection for PV panels is crucial, and only by taking adequate precautions can PV panels always be in a stable working condition and make full use of solar energy for us. In order to avoid the PV power station encountered high winds or extreme weather is destroyed, thus leading to the obstruction of PV power generation, seriously affecting the power supply, reduce the loss of the power station, therefore, in the PV panels of the site selection, installation and operation, we must take into account the risk factors, to take effective measures to prevent PV panels are blown away by the wind, breakage and other situations, to ensure that it is safe to operate. What aspects should we pay attention to?
1. The planning of site selection is important
When selecting the site, the size, shape, weight and wind direction of the photovoltaic panels and other risk factors should be considered, and should be avoided as much as possible to set up in high wind areas. At the same time, it is necessary to choose a windproof location to avoid the attack of storms and other bad weather. This can effectively reduce the risk of PV panels shaken by the wind.
2. The design and installation of the power station to be scientific enough
Ensure the quality of the building on which the photovoltaic is based, and the design mainly considers the support capacity and the prevention of typhoons, earthquakes and other risks. So in the power station program design, can moderately improve the strength of the photovoltaic bracket, component briquette design requirements, reasonable selection of components with better wind resistance tilt angle, can effectively reduce the strong wind on the photovoltaic power plant damage.
The installation of photovoltaic panels needs to be in accordance with the standard operation, the use of high-quality materials for fixing, and strengthen the fixing to ensure that the connection between the photovoltaic panels and the bracket is firm and not loose. When strengthening the fixing, more bolts can be used or the PV panels can be fixed to the bracket with a wire harness. In the installation process of photovoltaic panels, lightning protection measures need to be carried out, including the installation of lightning rods, lightning arrester, etc., to ensure that the photovoltaic panels will not be damaged in lightning weather.
3. Choose quality equipment
PV panel installation to choose the right bracket, to a certain extent, can increase the stability of the PV panel. Qualified photovoltaic modules need to undergo rigorous quality control testing before leaving the field, strict quality control. Selection of photovoltaic modules, consider for some special climatic environment areas, select a solid photovoltaic bracket, strict reference to the wind and seismic parameters of coastal buildings for design, select a strong pressure-resistant galvanized bracket, photovoltaic system array arrangement give full consideration to the wind of wind resistance of the Royal Wind Gap. If necessary, it is necessary to consider the weight of cement piers to improve the ability to withstand special circumstances.
4. Do a good job of photovoltaic power plant later operation and maintenance work
In addition to high winds, low temperatures and snowfall, haze will also have an impact on the photovoltaic power plant, hazy weather, the accumulation of particles on the surface of the photovoltaic module, the surface of the module will form a shield, the formation of hot spot effect, resulting in damage to the photovoltaic module, resulting in a further reduction in power generation. Therefore, it is necessary to regularly check the situation of the PV power station, always check the strength of the PV module, PV bracket, as well as the structure of the inverter room, etc., to repair the damaged places in a timely manner, and to clean the PV panels on a regular basis. Eliminate the hidden danger of safety and do prevention.
The windproof of PV panels is very important, if effective windproof methods are not taken, it will easily lead to PV panel damage and personal injury. Therefore, in the design and installation process of PV panels, it is necessary to give full consideration to windproof methods, choose suitable locations, brackets and strengthen the fixing to enhance the wind-resistant ability, in order to ensure the stability and safety of PV panels.
