The summer rainy season,Lightning flashes and thunder rumbles., heavy rain, hail and other severe weather often happens,Many people who install photovoltaic devices or intend to install photovoltaic devices are worried.Today, let's talk about the impact of bad weather, rooftop photovoltaic components and brackets, how we should deal with unexpected situations.
The effects of bad weather on the PV module and bracket:
If the PV module and the PV bracket were struck by lightning.Not only will damage to photovoltaic stents and inverters, but also the entire power grid system strike.Once struck by lightning, the power generation of the component will be reduced, the total power generation will be reduced, and the damage of the inverter will increase the cost of later maintenance.Such a natural disaster is inevitable, but what we can do is to minimize the harm.
Theoretically, the qualified photovoltaic component in grid connected photovoltaic system must pass through the positive static load (wind load, snow load) on the back of 5400pa, static load (wind load) of 2400pa and 25mm in diameter hail to the speed of 23m/s hit a rigorous test.Therefore, hail will not cause harm to photovoltaic power generation system.So the most important thing is that when you install photovoltaic devices,you should choose regular large brands of photovoltaic components manufacturers，Thus, photovoltaic modules are guaranteed.
Anti lightning measures for photovoltaic bracket:
1.The electrical equipment of metal parts is connected to the earth.The grounding system consists of four parts: grounding equipment, grounding body, introduction of line and earth. Good grounding is the important foundation of successful lightning protection measures
2.Choose the right roof.Because of its strong drainage capacity, the sloping roof will not appear too much water.So when building a house, it's better to consider the sloping roof.If the flat roof is not draining enough, the panels and the entire photovoltaic system will collect too much rain to soak up and destroy the photovoltaic bracket.
Anti rain measures for photovoltaic bracket:
1.Additional drainage system.Effective drainage, as long as the water does not appear too deep, the impact of solar panel and brackets will be relatively small.
2.Select the appropriate mounting angle.In this regard, reliable design or construction is particularly important.The designer will according to the local meteorological factors to design the safety tilt angle for solar bracket under the premise of ensuring power consumption.A good angle ensures that the photovoltaic device is not affected by bad weather.
3.Quality of photovoltaic modules.The surface of the amorphous silicon component is a layer of glass, the strength of tempered glass than ordinary glass,Toughened glass is the only protective layer of a component in extreme weather such as hail, snow, etc.So choose the regular manufacturers of photovoltaic components is particularly important.
In short, scientific design, high-quality photovoltaic components, lightning protection and hail prevention measures are important factors in dealing with bad weather.
The PV module has been installed in many rural families to shine on the roof, it also have an additional monthly income, this is really worthy of the roof of the small Treasuries! Now, PV had lit a beautiful countryside, what are you waiting for?
