It is always a good idea to install photovoltaic energy production on roofs. If you install solar panels on the roof, you can efficiently use solar energy to generate electricity and save electricity. The state now provides subsidies for the installation of power strips. With solar power, we generally use less electricity, saving electricity for your home. Installing photovoltaic power generation on the roof is relatively simple, generally speaking, it can be installed by a few workers in half a day.
1. Rooftop photovoltaic power generation is a mature technology that involves installing solar panels on top of the building and combining the existing building with the photovoltaic system. Use existing buildings efficiently without taking up additional land resources. He can progenerate electricity locally and consume electricity nearby, thus reducing transmission losses. Photovoltaic power generation occurs during the peak electricity consumption period during the day, which can effectively alleviate peak electricity demand. The state actively promotes the possibility of producing electricity if solar panels are installed. Unused electricity can also be sold to the State Grid and benefit from corresponding subsidies. It can be connected to the power grid, which means that two electricity meters need to be installed in the house, one is the electricity supplied by the electricity company and the other is the electricity produced by the panel solar.
2. The construction of a photovoltaic power plant requires support, which must be built on the roof or in an open space. Property rights on the roofs of urban buildingsbelong to all owners. If someone wants to build a photovoltaic power plant on the roof of a building, they must not only obtain the consent of all owners, but also involve the property management company, urban management bureau and other units. Many people in the city want to pretend, but it is not easy to do so. When installing, professional installers will design and install it reasonably according to the local climate. The photovoltaic plant will have no problem withstanding strong winds of magnitude 8 to 10.
3. Since the photovoltaic power generation system requires drilling holes in the roof during installation, if it is improperly installed or handled improperly, it is easy to damage the roof, leading to leakage accidents. water, mold, etc. ., and higher maintenance costs in the future. One of the disadvantagesThe most obvious side effects of installing photovoltaic solar power generation on your roof is that photovoltaic power generation destroys the waterproof layer of the house. The above is the answer to the question whether it is good or bad to install photovoltaic power generation on roofs and why.
Wind power generation and photovoltaic power generation
Which is cheaper, wind power generation or photovoltaic power generation? Wind power is low, wind power costs about 4-5 yuan per watt, and photovoltaic power costs about 7-8 yuan per watt. Low-light photovoltaic panels are cheaper. As photovoltaic power generation technology, especially photovoltaic panels, continues to mature, the application of photovoltaic power generation continues to expand. Photo energy productionVoltaics is also an emerging industry with good prospects.
Photovoltaic energy production equipment takes up less space and is also suitable for use in cities. Wind power generation equipment should be used in places subject to strong winds, and these places should be far from large cities.
Detailed information:
The advantages and disadvantages Photovoltaic energy production:
1. Advantages of photovoltaic power generation
Compared with commonly used thermal power generation systems, the advantages of photovoltaic power generation are mainly reflected in:
< p>①None risk of burnout;②Safe and secureReliable, no noise, no polluting emissions, absolutely clean (no pollution);
③It is not limited by distribution geographicales resources and can enjoy the benefits of building roofs, for example in areas without; electricity and areas with complex terrain;
④Can generate electricity and supply electricity on site without consuming fuel or erecting transmission lines;
⑤High quality of energy;
⑥Easy to use users need to accept emotionally;
⑦ The construction period is short and the time spent on obtaining energy is short.
2. Disadvantages of photovoltaic power generation
① The energy distribution density of irradiation is low, that is, it occupies a huge area
② The energy obtained is the same as that of the four seasons, day and night, and it is related to weather conditions such as cloudy and sunny weather.
③ At present, compared with thermal power generation, the cost of electricity generation is high.
④The manufacturing process of photovoltaic panels is not environmentally friendly.
To give you another idea, wind power is indeed inexpensive in terms of cost, but it also depends on where you use it.
The place you are using has no wind all day but the sun is strong, so you might as well install solar, which can produce more energy.
If you can't see the sun all day, use wind power.
You can also consider complementing wind and solar energy, which can increase the proportion of wind energy.
This should not be necessary. If you install it in your home, you are responsible for any safety issues. If you buy it, the manufacturer or seller should be responsible for this issue.
PS: If your house cannot consume this 3000W of electrical energy, it will be sentto the electricity grid; I can tell you that the number on your appliance meter will not go down if the energy is sent to the grid; electricity network, but will only increase.
