As the people's needs for a better life are growing, the consumption patterns of residents have undergone significant changes, from the satisfaction of the weight of the products to the pursuit of quality improvement, green consumption has quietly emerged, and the varieties of green consumption are constantly enriched, covering the traditional ecological organic Food, energy-saving and water-saving appliances, green building materials, green food, and gradually expand. The sales of health and environmental protection products such as air purifiers and water purifiers are booming, and recycled products are widely accepted by the market. Photovoltaic power generation and new energy vehicles have entered thousands of households. Now it has started PV heating and it is a new home with energy saving and environmental protection!
The heating of coal in the north is being carried out in a hot way. This is mainly to improve people's living environment and avoid the harm caused by smog. Photovoltaic + heating not only solves heating and heating in winter, but also saves summer heat by using cooling in summer. Thereby saving high electricity bills and achieving the three advantages of income, heating and cooling. The most unique is the longevity of photovoltaics for more than 25 years, which is the life that other electrical equipment can't reach.
In recent years, due to the state subsidies, it has been highly recognized by people everywhere. It is only because of the extension of the 531-subsidy limit. But it is still profitable, especially for the big consumers. PV has been no longer unfamiliar in recent years, but some people still consider whether there are potential safety hazards in photovoltaic power plants?
1. Does the household photovoltaic power station have radiation?
The household photovoltaic power station is composed of a photovoltaic module, a photovoltaic inverter, a photovoltaic support, and a photovoltaic cable;
Photovoltaic power generation converts light energy directly into DC power through the characteristics of the semiconductor, and then converts the direct current into an alternating current that can be used by us through the inverter. There is no chemical change and nuclear reaction, so photovoltaic power generation will not have short-wave radiation;
Therefore: Photovoltaic power generation is non-polluting, non-radiative, and inexhaustible clean energy.
2. Is it harmful to the body?
Because the PV module is not radiated, it can reflect some harmful UV rays in the sun, so it will not only harm but also help us to reflect some harmful UV rays!
At the same time, photovoltaics are clean energy. We use photovoltaic power plants to generate electricity, which is equivalent to saving 0.4 kilograms of standard coal, while reducing pollution emissions by 0.272 kilograms of carbon dust, 0.997 kilograms of carbon dioxide, 0.03 kilograms of sulfur dioxide, and 0.015 kilograms of nitrogen oxides. .
In this way, our air quality will get better and better, and the smog will be reduced!
3. Will the roof mount of the solar photovoltaic power station be damaged?
Household roofs generally have a load-bearing capacity of 200KG per square meter. Currently, the polycrystalline silicon photovoltaic modules and PV solar mounting bracket systems commonly used are 30KG per square weight, and the bearing problem is also the first consideration for each PV power plant design. Professional design will fully consider Fixed load on the roof, wind load, snow load, seismic load, etc.
Therefore, there is no problem with the roof-mounted solar photovoltaic power station.
