As far as I know, solar photovoltaic power generation is not harmful to the human body. The photovoltaic power generation system converts solar energy into electrical energy based on the principle of voltaic effect produced by light. It is pollution-free and radiation-free. Electronic devices such as inverters and distribution cabinets have passed EMC (electromagnetic compatibility) testing. so there is no harm to the human body. However, the photovoltaic power generation process may produce a certain amount of light pollution, which may cause some irritation to human health. In daily life, you must take protective measures to avoid direct exposure to light pollution.
Is domestic solar power generation profitable
A 5 kW household can be installed on a 100 square meter roof Photovoltaic power station, in the market The price of photovoltaic system is 7-9 yuan per watt, which means it will cost 35,000-45,000 yuan to install 5 kW.
The prices of photovoltaic power generation equipment are different and the materials are different. There is monocrystalline silicon and polycrystalline silicon. Prices are different from polycrystalline silicon and have higher power. generation efficiency.
Notes:
Nationally, the cost of solar photovoltaic power generation is 8-12 yuan per watt. For example, a 100 square meter roof can produce 10 kilowatts. Calculated at 10 yuan per watt, the final total package price is 100,000 yuan. This price includes design, equipment, construction and connection to the network, etc. The specific price is yet to be determined based on demand and installed capacity.
The profitability of home solar energy depends on the circumstances.
The investment cost of home solar power generation is relatively high, and installing a home photovoltaic power generation system with a power of 5 kilowatts will cost a certain amount . Even if the government provides subsidies, the real cost remains higher. In addition, since the solar power generation system relies on solar radiation, its power generation will be affected by weather conditions and other factors, resulting in unstable power generation efficiency.
Revenue from domestic solar power generation mainly comes from self-use and power grid surplus. In some areas, power companies buy the electricity produced by home photovoltaic power systems at a higher price.evé, but this price is generally low and it is difficult to recover the cost in a short time. In some regions, the government will offer preferential policies, such as free installation, tax exemptions, etc. These policies can reduce the cost of home solar power generation and increase its benefits.
Therefore, the question of whether it is cost-effective to install a home solar energy system must be evaluated on a case-by-case basis. If your electricity needs are modest and you have access to government incentives, it may be cost-effective to install a solar home energy system. But if your electricity needs are high or you don't have access to government incentives, considering whether to install a home solar energy system may take more time.
