Photovoltaic power generation should be borrowed from natural products to serve human beings, and the energy of the sun should be inexhaustible, mainly because the investment is not much, but the current market is not widely used, is the investment too large.

<> reports said that once upon a time, when electric fans, rice cookers and other electrical appliances first appeared in people's field of vision, no one dared to assert that this would become people's standard, because when these new things appeared, it was difficult to change thinking, and it was even more prohibitive.

However, with the maturity of photovoltaic power generation technology, the continuous decline of photovoltaic equipment, coupled with the continuous improvement of people's awareness of photovoltaic power generation, more and more people are installing photovoltaic and using photovoltaics, and photovoltaic power generation has become the standard configuration for many families in just a few years.

Experts said that China, as a major energy manufacturing and consuming country, has been doing several things in recent years: developing new products that save energy and reduce consumption, developing clean and renewable new energy, and promoting the technological transformation and upgrading of industrial enterprises, and photovoltaic power generation coincides with the country's macro strategy, which has a new situation of rapid development under the dual influence of policy and market, and from the perspective of the market, this is also the inevitable result of market choice.

The technology that converts solar energy directly into electrical energy is called photovoltaic power generation technology. It is the use of the photogenerated volt effect at the interface of semiconductors.

It is a technology that converts direct light energy into electrical energy. The key element of this technology is the solar cell. Solar cells can be encapsulated and protected in series to form large-area solar cell modules, and then combined with power controllers and other components to form photovoltaic power generation devices.

The advantage of photovoltaic power generation is that it is less limited by geography, because the sun shines on the earth; The photovoltaic system also has the advantages of safety and reliability, no noise, low pollution, on-site power generation and power supply without fuel consumption and transmission lines, and short construction period.

Photovoltaic power generation is based on the principle of photogenerated volt effect, using solar cells to directly convert sunlight energy into slow building electricity. Whether it is used independently or connected to the grid for power generation, photovoltaic power generation system.

Mainly consists of solar panels (modules), controllers and inverters.

It is composed of three major parts, which are mainly composed of electronic components.

The composition does not involve mechanical parts, so the photovoltaic power generation equipment is extremely refined, reliable and stable, with long service life and easy installation and maintenance. Theoretically, photovoltaic power generation technology can be used in any occasion that requires power, from spacecraft to household power supply, to megawatt power stations, to small toys, photovoltaic power is everywhere. Solar photovoltaic power generation.

The most basic element is the solar cell (sheet), which has monocrystalline silicon.

Polysilicon, amorphous silicon and copper indium gallium selenide thin-film cells, etc.

It's already very mature. The next step is to continue to improve the conversion efficiency of photovoltaic power generation and strive to approach the conversion efficiency of electronic level.

Very mature. There are good solutions in the grid-connected scheme, self-consumption, surplus power grid, etc., and there are no barriers to the gap in technology. Different manufacturers are mainly reflected in the same equipment, especially the bright inverter and related components, and there is a lot of room for choice.

At present, the most widely used is crystalline silicon photovoltaic power generation technology.

The more mature technology is the crystalline silicon cavity stove photovoltaic power generation technology, which is also the most widely used. Monocrystalline silicon or polycrystalline silicon solar plates, batteries, controllers, if AC and DC transformer AC devices are used, nanofiber for large-scale photovoltaic power generation also needs to go through step-up and step-down equipment. Many of the equipment that needs to be used for power generation, transformation and transmission are very mature.

The existence of photovoltaic panels has high cost, low power generation, high requirements for the use of the environment, and the huge difference between the cost of power generation and investment is huge.

The current photovoltaic power generation technology is mature, and this technology is also slowly maturing.

As an emerging form of agriculture, photovoltaic agriculture has been widely used in the field of agriculture, covering planting, forestry, animal husbandry, fishery, etc., the most common is the agricultural photovoltaic greenhouse This model has become a hot direction when the mountain is fiercely down, the current situation and prospect analysis of photovoltaic agriculture for you Broadly speaking, photovoltaic agriculture is the solar power generation is widely used in modern agricultural planting, breeding, irrigation, pest control, As well as a new type of agriculture in the field of agricultural machinery power, it takes thin-film solar energy facilities and agricultural integrated grid-connected power station as the core, integrates thin-film solar power generation, the application and promotion of agricultural optoelectronic engineering, modern agricultural planting and breeding, processing and comprehensive utilization, agricultural planting and breeding technology exchange and promotion, personnel training, sightseeing agriculture, agricultural product logistics and other functions in one, photovoltaic agriculture combines solar power generation, modern agricultural planting and breeding, and efficient facility agriculture, so to speak, Photovoltaic agriculture is a transformation of the production mode that realizes the transformation of farms into factories and fields into workshops.

Dear, what is your specific question, can you say a little more specifically?

Hello, I am glad to answer for you: 1. The growth of the photovoltaic industry is promising, when the industry is growing, you will have more growth opportunities in this industry. Standing on the tuyere, a talent can definitely fly.

2. When you work in the photovoltaic industry, the work you do will help or use more photovoltaic power generation to improve the environment as a whole, reduce pollution and affect climate change. This is also the consensus of all mankind, and for many, this resume is enough to be a source of pride. It is a job, and it is a profession, you can make money to support your family, and you can also be idealistic, such a thing, I also admit it3, the increase of photovoltaic experience, the income is also increasing, and the photovoltaic industry is an industry with relatively high returns from the beginning 4, the photovoltaic industry, which allows you to retire!

The benefits of home photovoltaic power generation include three parts:

1. Subsidies to make money: national subsidies + provincial subsidies + city and county subsidies (slightly different from place to place), whether you use it or sell it, as long as the electricity is subsidized.

2. Save electricity bills: power generation for your own use, no need to pay electricity bills, which is equivalent to making money.

3. Sell electricity to make money: Sell inexhaustible electricity to the state, and sell electricity according to the benchmark electricity price of local coal-fired desulfurization units. (Electricity prices vary slightly from place to place).

Return on investment calculation

Taking the three types of areas in Shandong as an example, the installation of a 5kw family power station will invest about 40,000 yuan according to the market. An average of 20kw h can be sent a day, and 7300kw h can be sent a year, according to 30% for self-use and 70% sold to the national grid

Subsidy income: 7,300 * yuan (excluding provincial and prefecture-level subsidies).

Electricity cost savings: 7300 * 30% * electricity bill) = yuan.

Income from electricity sales: 7200*70%*RMB.

Combined, a year's income: 3066+ yuan.

It takes almost 6 years to pay back, and the average operating time of photovoltaic power plants is 25 years, which is equivalent to the net income of the next 19 years.
