Since spring, China's widespread weather turned warm, and with the arrival of cold and warm air, accompanied by strong convective weather, thunderstorms, high winds, and hail and other extreme weather, each time this time photovoltaic power plant workers are particularly worried, worried about photovoltaic power plant will not be a serious disaster.
Response to thunderstorm windy weather, PV power plant design and installation should not be ignored
The impact of thunderstorms and high winds on photovoltaic power plants is generally reflected in the photovoltaic modules are blown over by high winds, high winds blowing over the photovoltaic power plant, many people's first reaction will be to think of the photovoltaic power plant quality is not good. Photovoltaic power plant quality is indeed one of the important factors. However, there are two other factors that are also very important, and often ignored. In fact, it is the design and installation of photovoltaic power plants.
First, the design of photovoltaic power plants.
The installation of a photovoltaic power station with the building house is first needed to design. According to the owner of the roof, the house around there is no shade, the local sunshine hours, etc., at the same time, must be considered is the local 50-year wind data, lightning protection devices also need to included. This design out of the photovoltaic power station is the most in line with the actual situation of the local owners, is also able to resist the thunderstorm wind. Some integrators are likely to have no design at all, on a simple measure of the owner's roof, the installation capacity, and the installation angle set.
Second, the installation of photovoltaic power plants.
Photovoltaic power plant installation is not a place to slacken! Installation must be strictly according to the design, and meticulous! Screws must be tightened! The pressure block must use the matching, side pressure on the side pressure, medium pressure on the medium pressure, do not mix! Do not take other types of pressure block used indiscriminately! Mixing with the use of the risk! Small details determine success or failure! These small problems are fatal when it comes to high winds!
Coping with hail, the quality of photovoltaic modules is the key
It is true that the glass on the surface of the photovoltaic module is tempered glass. Moreover, as long as the PV modules are produced by regular manufacturers before leaving the factory, they will go through a series of tests such as hail.
The standard hail test is the use of a 25mm diameter steel ball, with a speed of 23m / s impact PV modules. Some highly demanding companies may use more stringent energy than the standard close to 2 times the IEC standard (30.7m/s) to test.
In addition, there are a series of tests such as mechanical load, thermal cycling, damp heat, and damp freeze.
So, when buying a PV plant, don't be greedy for cheap! Be sure to choose a well-known big brand of photovoltaic power plant! Well-known brands of photovoltaic power plants, at least in the factory product quality is guaranteed!
Natural disasters can not be prevented?
Our photovoltaic power station, every day through the wind and sun, can not take some measures to prevent hail damage, thunderstorms, and wind damage?
There are. That is to buy insurance! Must buy insurance! Natural disasters we can not predict, but we have a way to minimize our losses after encountering natural disasters, that is to buy insurance!
Buy insurance is the last protection after the disaster, before that, choosing the well-known big brand of photovoltaic power plant products is the best protection!
