If you want to install it in your own home, I suggest you not install it now. It's not economical. A certain room must be equipped with a corresponding collecting surface. If it's enough for the winter, that's enough. will be very useless in summer. If you do not want to install it in summer, this waste will increase conventional energy consumption in winter. Once there is a problem in the subsequent operation, the maintenance will never be as convenient as the shopkeeper says. .Personally, I think this technology is not very mature yet, and I am still moving forward, so when it comes to home decoration, you need to be careful. I have already made a solar heating plan for home decoration, but it doesn't matter how. I calculate it, I think it's a loss. This is my personal opinion.
The advantages and disadvantages of photo energy productionovoltaic energy on household roofs are as follows:
The advantages of photovoltaic energy production on roofs in rural areas:
1. Photovoltaic power generation is very suitable for self-built houses in rural areas with unused roofs. They can use the roofs for investment purposes.
2. A one-time investment in photovoltaic power generation will generate lifetime income. Once the installation is complete, you will receive a fixed amount every day.
3. Solar power generation is safe and reliable, and solar power is inexhaustible and clean energy.
4. Solar energy is an ideal clean energy source. The production of photovoltaic solar energy produces no waste, does not produce a greenhouse effect and produces no noise or harmful gases.
5. Photovoltaic power generation can significantly reduce operating costs. The productionphotovoltaic solar energy does not require fuel, it only needs the sun to produce electricity.
Disadvantages of rural rooftop photovoltaic power generation:
1. The lifespan of photovoltaic power plants is not eternal. The lifespan of general photovoltaic panels will decrease after 35 years and the power. production efficiency Efficiency will be reduced.
2. Photovoltaic solar energy production relies on the Volt effect generated by the semiconductors inside the solar panel. The roof frame was not reinforced early in the design. Since the photovoltaic power generation equipment itself is very heavy, it can damage the roof structure, especially if it is an old house, it is very likely to damage the roof .
Application fields of photovoltaic energy production:
1. Solar powere of user: (1) Small power supply ranging from 10 to 100 W, used in remote areas. without electricity, such as electricity for military and civilian life on the plateaus, islands, pastoral areas, border posts, etc., such as lighting, televisions, tape recorders, etc. (2) domestic roof-connected electricity generation of 3 to 5 kW; system (3) Photovoltaic water pump: solve the problem of drinking water from deep wells in areas without electricity or irrigation.
2. Transportation fields such as navigation beacon lights, road/railway signal lights, warning/signal lights, Yuxiang street lights, high altitude obstacle lights, wireless phone booth power supply wire for highways/railways, etc.
3. Power supply for home lighting: such as garden lights, street lights, lightningportable lights, camping lights, mountaineering lights, fishing lights, black light lights, rubber tapping lights, energy saving lamps, etc.
