Is it practical to install household photovoltaic power generation in rural areas?

The so-called household photovoltaic distributed power generation is mainly a civil household photovoltaic power station, and "household" refers to a distribution that is separate from industry and commerce, mainly whether it is a ground power station or a rooftop power station.

Household distributed photovoltaic power generation is actually also household photovoltaic. Mainly on the roofs of rural areas, people buy power stations and install them on the roof, generate electricity for their own use during the day, and sell the inexhaustible electricity to the national grid. There will be a subsidy for installation in 2020, but there will be no more next year.

The system of household photovoltaic mainly includes: photovoltaic modules (photovoltaic panels), inverters, meter boxes, and brackets. Modules and inverters are the core components of the entire system.

At present, Zhejiang Carbon Bank's business is mainly to provide household photovoltaic for the people, and through the photovoltaic loan of the Industrial and Commercial Bank of China, the power station can be installed directly with zero down payment. Very convenient. If you really want to have an in-depth understanding of household photovoltaics, you can learn about the carbon profit synergy app, which has a lot of different cooperation models and information, I hope it can help you.

Of course, the power station itself is equipped with a roof or balcony, does not occupy the construction area, only invests tens of thousands of yuan, and can earn income through power generation for many years, for 25 years, according to the news, there are also state subsidies.

In March last year, a 5 kilowatt sunshine shed of Sungrow Power Supply Company was installed on the roof of my house, which generated more than ten degrees of electricity every day.

Summary. The installation of photovoltaic power generation in rural areas is not very reliable. China is committed to energy conservation and emission reduction, and has also launched a lot of related policies, rural photovoltaic power generation is one of them.

Originally, this policy was a good thing, and farmers could make money by installing a few photovoltaic panels on the roof of their homes, and this is the starting point of the new routine. Many ** people see the loopholes of photovoltaic power generation and go to the village to fool the ignorant old people in the name of national policy. There have been ** done relevant reports before, exposing the **.

For example, the first of a certain company entered the village under the banner of "new energy company" and national policies to promote photovoltaic power generation to the elderly. This new energy company is actually a company that sells photovoltaic power generation equipment. But if you want to install it, you can also agree with it, after all, photovoltaic power generation can save energy and save money for rural families, but you should be careful not to fall into it.

Very good. The advantages are as follows:

1. Safe and reliable, no noise, no radiation, no fuel consumption, no mechanical rotating parts, low failure rate and long life;

2. Environmental protection and beauty, not limited by geographical location, short construction period, random scale, easy to disassemble and assemble, and easy to move;

3. Ready-to-use, low cost of disassembly and damage, can be easily combined with buildings, no need to embed high transmission lines, and can avoid the damage to vegetation and environment and engineering costs when laying cables over long distances;

4. Stable voltage, high power quality, widely used in a variety of electrical equipment, very suitable for villages, farms, mountains, islands, highways and other remote places of electricity, but also a very good emergency backup power supply.

A set of photovoltaic equipment is also worth a lot, if it is for home use, there is not much electricity to install a photovoltaic power generation, I don't think it is worth it.

Dear, hello, I am happy to answer for you: Is it good to install photovoltaic power generation at home Answer: It is not good to install photovoltaic power generation at home.

The disadvantages of installing photovoltaic panels in homes are as follows: Photovoltaic power generation can only be used during the day, and it still needs to be powered by the national grid at night. The power generation in the winter is only 20% of that in the summer, and the power generation is insufficient.

On rainy days, power generation drops to single digits. If the installation is not secure, there is a risk of falling and injuring people. Damage to the roof structure and damage to the roof waterproofing layer.

When installing, you need to punch holes to install the bracket, which will cause some damage to the roof. Residual current or leakage is prone to electric shock accidents. If there is strong wind, there is a risk that the PV panels will be blown over and fallen.

There will be a little bit of radiation, and long-term residence will have adverse effects on the human body. Home installation without professionals, long-term inspection, regular protection. Rust cannot be found at the first time, and it is easy to cause danger.

There is a potential risk of causing a fire.

Summary. Hello dear. I'll take care of your questions.

According to the problem you described, the installation of photovoltaic power generation in rural areas is relatively stable and reliable compared to other areas, because there is more solar radiation in rural areas, the power generation is more stable, and the installation cost is relatively low. In addition to this, there are some advantages of photovoltaic power installation, such as:1

Not affected by geographical environment: Photovoltaic power generation can be installed in any location, regardless of terrain and landforms, such as valleys, mountain tops, etc. 2.

If you have a lot of sunlight in your area, photovoltaic power generation is a very reliable source of energy.

Disadvantages of photovoltaic power generation.

1. Low conversion efficiency.

The conversion efficiency of photovoltaic power generation refers to the efficiency of converting light energy into electrical energy. At present, the conversion efficiency of crystalline silicon photovoltaic cells is 13% to 17%, and the conversion efficiency of amorphous silicon photovoltaic cells is only 6% to 8%. Officially, because of the low photoelectric conversion efficiency, the power density of photovoltaic power generation is also very low, so it is difficult to form a high-power power generation system.

Low photoelectric conversion efficiency is an important factor hindering the development of photovoltaic power generation.

2. You can only work during the day.

Photovoltaic power generation can only generate electricity with light, so photovoltaic power generation can only generate electricity during the day, and cannot generate electricity at night, and most of our usual electricity is at night, and the working characteristics of photovoltaic power generation do not match our living habits.

3. It is greatly affected by the climate and environment.

Long-term rain and snow, cloudy days, foggy days and even changes in cloud cover will affect photovoltaic power generation. There can be no debris on the solar cell plate, once there is, the efficiency of photovoltaic power generation will be reduced a lot.

4. Strong regional dependence.

The geographical location is different, the climate is different, and the sunshine resources in each region vary greatly. Photovoltaic power generation systems will only work well when applied in areas with abundant solar energy resources.

5. Low energy density.

Although the total amount of energy irradiated by the sun on the earth is extremely huge, because the surface area of the earth is also very large, and most of the earth's surface area is covered by the ocean, the solar energy that can really reach the surface of the land is only about 10% of the radiation energy that reaches the earth's range, resulting in less solar energy that can be directly obtained on the unit area of the land. The highest value of solar irradiance on the Earth's surface is about 1kwh m in most areas of the Earth. Photovoltaic power generation is actually the collection and utilization of low-density energy from solar energy.

6. It covers a large area.

Due to the low energy density of solar energy, this makes the area of photovoltaic power generation will be very large, 10kw photovoltaic power generation power occupies an area of about 100m 2, and the average power generation power per square meter area is about 100w. With the maturity and development of building-integrated photovoltaic power generation technology, more and more photovoltaic power generation systems can use the roofs and facades of buildings and structures, which will gradually overcome the problem of large area occupied by photovoltaic power generation.

7. The cost of the whole system is very high.

The cost problem is the most important factor restricting the wide application of photovoltaic power generation, and the cost of photovoltaic power generation is several times that of thermal power generation and hydropower generation. The high cost of the system is mainly due to the photovoltaic modules, but with the update and iteration of technology, it is only a matter of time before the module cost is reduced. At present, the solar panel on the market is about 4 yuan per watt, and it will be even lower in the future.

8. The manufacturing process of crystalline silicon cells is highly polluting and high energy consumption.

The main raw material for crystalline silicon cells is pure silicon. The extraction of pure crystalline silicon from sand (silica) requires multiple chemical and physical processes, which not only consume a lot of energy, but also cause a certain amount of pollution to the environment.

The installation of photovoltaic power generation will have a certain amount of radiation, but your electricity must be cheaper, and you may be given a certain subsidy.

Photovoltaic power generation has no effect on the villagers. 1. Solar photovoltaic power generation does not produce any waste gas, waste water, waste residue and other wastes. 2. There are no rotating parts in the process of operation, and there will be no noise pollution.

The principle of photovoltaic power generation is the photogenerated voltaic effect, the solar cell module generates direct current under the condition of light, and after a certain series and parallel summary, it is connected to the grid-connected inverter and converted into a 50Hz AC230V 400V power supply, without any high-frequency alternating current and electromagnetic radiation in the whole power generation and conversion process, and will not cause harm to the human body. If it is a poverty alleviation project, poor households should be able to have part of the income every year, please consult the local village committee for details. If it is installed in the villagers' own homes, of course, the benefits can only belong to themselves.

If you are satisfied with the service, please give me a thumbs up, thank you!

Environmental protection, resource saving, is a new energy. Believe in the arrangement of the state and **.

As long as there are no problems with the load-bearing structure of your house, it can be installed, and there is nothing bad about it.

In fact, the benefits of installing photovoltaic power generation are very large, and photovoltaic power generation can make full use of the sun's rays, which is a manifestation of this energy-saving method.

What about after you put it on? He has that subsidy, and there is a subsidy after installing it, as for the drawbacks? Basically, no, you can't dry anything on the roof.
