How much money can be made a year by building 50,000 watts of solar power

First of all, we need to know the principle of the grid-connected photovoltaic power generation system and what equipment is needed.

First, the working principle of photovoltaic power generation system:

The high-performance solar cell modules are centrally installed on the roof through the bracket, and after series and parallel, they form a solar cell array, which absorbs sunlight and generates direct current, which is converted into alternating current for home use after passing through the photovoltaic inverter and uploaded to the power grid.

Second, the system composition:

Mainly: photovoltaic modules, inverters, brackets, DC cables, AC cables, subsidized meters, and two-way meters.

Third, the market **:

The market price of photovoltaic systems is generally 8-12 yuan per watt. Generally, the cost of installing a 5kw solar power generation system in a family is about 4-60,000 yuan.

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).

5. Calculation of return on investment

toShandongFor example, in the third type of area, 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.

According to the first floor, the income for a year: 3066+ yuan.

The income from electricity bills earned is too low, and there is a certain risk of building on your own roof.

After the construction of the power station is completed, the consumer buys the power station panel through Nenghuanbao, and the consumer has the ownership of the battery panel, and the power station continues to generate electricity, and the electricity income generated belongs to the consumer.

And when consumers want to give up the ownership of the panels, Nenghuanbao will also buy, for consumers, the risk is very small, and the power station is maintained by professionals, which can continue to maintain the normal power generation of the power station!

Maybe you first have to count the annual sunshine hours and sunshine intensity in the local area. Only with these data is it possible to calculate the amount of departure. The average square solar PV panel is about 100 to 150 watts. However, this figure is based on ideal lighting.

The cost varies slightly from place to place. Monocrystalline silicon is slightly more expensive than polysilicon, with the experience of our electric power design institute, the cost for reference is about 5,000 yuan per kilowatt, and the previous paragraph is said to have 4,000 yuan. 500 kilowatts, the total cost is about 2.5 million yuan.

Definition of noun: When a photon irradiates a metal, its energy can be absorbed by an electron in the metal, and the energy absorbed by the electron is large enough to overcome the internal gravity of the metal to do work, escape from the metal surface, and become a photoelectron.

Photovolt effect", abbreviated as "photovoltaic effect". Refers to the phenomenon that light causes an uneven semiconductor or a potential difference between different parts of the semiconductor and the metal combined. It is first of all the process of converting photons (light waves) into electrons and light energy into electrical energy; Secondly, there is the formation of the voltage process.

With voltage, it's like building a dam, and if the two are connected, a loop of current will be formed.

The basic principle of photovoltaic power generation is the "photovoltaic effect". The task of a solar specialist is to do the job of creating the voltage. Because the voltage is to be manufactured, the solar cells that complete the photoelectric conversion are the key to solar power generation.

The composition of a photovoltaic power station is mainly composed of solar cell modules, brackets, inverters, combiner boxes, lightning protection, cables and other parts, depending on whether the panel components you use are class A or class B, the general photovoltaic bracket is almost the same, and the other inverters are quite different, and the first-line brands are Schneider, Sunshine, Huawei, etc. At present, the cost price of a system is about 10 yuan wp, and the large-scale power station may rise a little. A 500 kilowatt photovoltaic power plant will probably be between 4.5 million and 5 million.

About 100 million yuan of investment, according to the annual average irradiation of Shandong, about 37 million per year can generate about 37 million annual costs.

It is a power station based on photovoltaic power generation system, including various buildings (structures) and auxiliary facilities such as overhaul, maintenance, and life. When a photon irradiates a metal, its energy can be absorbed by an electron in the metal, and the energy absorbed by the electron is large enough to overcome the internal gravity of the metal to do work, escape from the metal surface, and become photoelectrons.

At present, China's photovoltaic power generation system is mainly a DC system, that is, the electric energy emitted by the solar cell is charged to the battery, and the battery directly supplies power to the load, such as the solar household lighting system used more in northwest China and the microwave station power supply system away from the grid are DC systems.

This type of system has a simple structure and low cost, but it is difficult to achieve system standardization and compatibility due to the different load DC voltages (such as 12V, 24V, 48V, etc.).

If you follow the easiest way to install. One million can hold an installed capacity of about 250 kilowatts. If you use electricity, it is about ** yuan. and calculated on a 25-year basis with a combined annual interest rate.

About 19%, about 5 years can be the best cost.

One million yuan, it is okay to invest in photovoltaic enterprises and buy shares, or set up a company to build photovoltaic power plants. One million yuan alone is too little to participate in the photovoltaic industry. The investment in this industry is huge.

1 million investment How much money do I earn a year, about 500,000 a year.

I can say that your money is not enough for other people to buy screws, and they will not accept such a small investment at all.

Regardless of the cost of land, the power generation cost of photovoltaic power stations has been controlled below 1 yuan. However, it is not cost-effective to bear the cost of large-scale power generation at present. The goal of China's photovoltaic development is to improve the economics of solar power generation, and strive to reduce the cost of photovoltaic power generation to less than yuan.

According to the subsidy plan, the current estimated installed cost of household photovoltaic power generation projects that have been approved and connected to the grid is yuan, and if the installed capacity of each household is 3kw, the average installation cost per household is about 28,000 yuan. According to the intensity and duration of local radiation exposure, the installed capacity of 3kW is theoretically about 15 kWh per day.

Precautions for installation of solar power system:

1. The installation azimuth angle and inclination angle of the battery plate array need to be considered. The installation method is about 45 degrees to the ground level, and the longer the sunlight exposure, the better.

2. Avoid blocking between the panels. Including surrounding buildings (telephone poles, eaves, etc.).

3. Stability and firmness of stent placement.

4. The construction site of the system must be open, and there shall be no tall buildings or other things blocking the sunlight at the installation of solar cell array.

Calculated with a photovoltaic cell of 50 yuan per watt, your monthly electricity bill is 50 yuan, 3,000 yuan for 5 years, 100 kilowatt hours per month, about kilowatt hours per day, and an average of 7 hours of light per day (if it is a tracking type that will take a little more time, but the cost increases), that is to say, the 500-watt battery board will be fully powered, full load work, and the photovoltaic panel investment will be 25,000 yuan, labor costs, batteries, AD converters and other equipment placement costs are calculated separately, and it is impossible to spend 5 years**.

Hello Hello I am happy to answer for you: how much electricity can be generated by 10,000 square meters of photovoltaic solar power generation in a yearAnswer: Hello 10,000 square meters can be installed with a 1430 kilowatt distributed photovoltaic power station, with an average annual power generation of 1801800kWh (kWh).
