In solar panels and solar batteries, only a few heavy metals are harmful, the vast majority of substances are harmless, and so far, there is no scientific research to show that solar panels will cause harm to human health. Furthermore, installing solar panels reduces the burning of fossil fuels, which reduces the frequency of cancer while protecting the environment.
Perhaps the biggest concern is that solar panels produce low-level electromagnetic fields. Although it is a form of radiation, this radiation is almost identical to that produced by appliances such as hair dryers, radios and televisions, and is not harmful to the human body.
1. Hurricane weather: the wind load of the solar panel is 2400pa, so in hurricane weather, generally speaking, is safe, but when the wind is too strong to strengthen the stability of the solar panel, you can choose to strengthen the solar panel bracket or thicken the concrete and steel to ensure its safety.
2. Sandy weather: sandstorms and other disasters may lead to the accumulation of sand and dust on the solar panels and thus the occurrence of polythermal, not only there is a certain degree of safety hazards, but also will make the power generation efficiency is reduced, so it is necessary to clean up the solar panels.
3. Snowstorms: solar panels have a certain pressure-bearing capacity (5400pa), so there is no need to worry about the snow buildup is too thick to damage the solar panels, but in order to enhance the durability of the solar panels should be cleaned up in a timely manner snow.
4. Thunderstorms: solar panels are connected to the grounding device, so there is no need to worry about lightning damage to the solar panel.
The answer is yes, but the probability is very small. Solar panels, like many electrical appliances, are closely connected to electricity, which can cause a fire.
To prevent fires from occurring, we can protect switches from short circuits, overloads, and excessive voltage. Safety can also be ensured by installing fire-fighting devices, setting up fire escapes, and regular inspection and maintenance.
1. Check whether there are loopholes and other problems on the roof when installing solar panels, in addition, some tile roofs, glass roofs, etc. should also consider their load-bearing capacity.
2. Regularly check the wiring to prevent problems such as loose joints and aging circuits from affecting safety.
3. Regularly check the grounding device of the solar panel and the stability of the bracket.
Beneficial. On the one hand, it can extend the service life of the roof. Because solar panels can provide a layer of protection for the roof, avoiding the sun, hail and other direct damage to the roof. On the other hand, they can attenuate the temperature changes inside the house. In the summer heat at noon, direct sunlight on the roof will cause the indoor temperature to rise sharply, at this time the solar panels can play a certain cooling effect by absorbing sunlight.
If you take into account all the dangerous factors and do a good job of protection when installing solar panels, and then carry out regular inspection and maintenance, then it is absolutely safe to install solar panels on the roof.
