How much does a PV power plant investment cost

The core components in the cost are solar panels and inverters, which are also the two most expensive devices. The system of string circuit design uses a centralized inverter, and the system factory sells 10 yuan W; The parallel circuit design uses a micro inverter, which is safer for household use but is more expensive, and the factory direct sales are 12 yuan -15 yuan W, depending on what inverter you use.

After 08 years of industrial competition, the technology of solar panels has been very mature, homogeneous in technical capabilities, there is no fundamental difference, the same power, the scale of manufacturers is different, the selection of raw materials is different, and the first is different. For example, a bad EVA film will affect the life of solar panels, and the cell and assembly process will affect the power generation efficiency, so it is still necessary to choose a first-line brand. The purchase channel is also very important, now many manufacturers have their own project companies, the system and products are directly sold, all bear the responsibility of warranty, and the purchase on the online platform is not very reliable.

There is also a difference between solar panels is monocrystalline polycrystalline, the difference between monocrystalline and polycrystalline is quite big, the ** per watt of monocrystalline board is about 5 yuan, polycrystalline is cheaper than monocrystalline 6-7 cents, monocrystalline is purer, higher power generation efficiency, high light sensitivity. But polycrystalline also has its advantages, and there are also a lot of haze days in the eastern coastal areas, and polycrystalline has good tolerance in such weather conditions, and sometimes the power generation is higher than that of monocrystalline.

The power generation capacity of 1kw is about 1200 degrees a year, depending on the roof orientation and whether it is the best inclination, there will be some ups and downs.

Depending on how many kilowatts of system you have to install, a 3kw household power station is about 2 30,000. Since you have invested, you must hope for a higher rate of return, which depends on whether the power generation is high. Don't look for those small brands that are assembled, they can't guarantee the quality, let alone generate more electricity.

It also depends on whether you are investing in a large power station or a small residential power station.

Large-scale ground-mounted power stations must be more than one million, and small-scale ones are tens of thousands and hundreds of thousands.

This is based on the power station equipment of the year**, which mainly includes two parts of the cost, mainly in the construction of the station and operation and maintenance.

1. Installation cost of photovoltaic power station.

The cost of photovoltaic modules, inverters and other power station equipment is very low, the first level of photovoltaic modules has reached the yuan w, the first solution of the first is in the yuan w, and the installation cost of the power station of 10kw is about 35,000, compared with a few years ago, the installation cost has been reduced by more than half.

2. The operation and maintenance cost of photovoltaic power station.

At present, the service life of photovoltaic power stations is about 25 years, which requires regular maintenance, and photovoltaic modules need to be cleaned and repaired. In addition to providing installation and construction services, Zhejiang Carbon Silver Company provides annual operation and maintenance services of 200 yuan (different service providers), and the replacement of faulty devices is paid separately, calculated according to 25 years, and the operation and maintenance cost is more than 5,000 yuan.

According to the current construction cost and electricity cost, taking the 50-square-meter flat-roof household power station as an example, the total construction investment is 30,007, the annual income is about 14%, and the total income of power generation is about 120,000, and the power station can recover the cost in the fifth year.

To understand, you can also understand the "Carbon Earnings Synergy" app, which has a detailed introduction. Carbon Bank also provides photovoltaic loans, with a maximum loan term of 8 years and an interest rate of up to 150,000 yuan.

1. Installation cost of photovoltaic power station.

It mainly includes photovoltaic modules (solar photovoltaic panels), inverters (DC voltage to AC voltage), distribution box. Plus the cost of construction work. The following is what I checked on the industry platform "Carbon Earnings Synergy" APP (July 16, 2020 ** price) Carbon Earnings Synergy.

Photovoltaic modules LONGi's monocrystalline 355W modules, LR4-60HPH 355W, 543 yuan per piece, that is, yuan W (tax included), other products such as Canadian Solar 340W, CS3L-340P, yuan, that is, yuan W

The inverter Growatt three-phase 17kw growatt mid is 3850 yuan per unit, which is yuan w

Distribution box such as Changsong 10kw distribution box 699 yuan block.

The pricing of the main accessories is as above, if it is an integrated solution, the solution (including three major parts, distribution services, insurance, etc.) will be given according to the carbon earnings synergy.

It can be seen that the investment cost of photovoltaic power generation is now very low.

As of May 27, the module has dropped to yuan w. The ** mentioned in this article is the actual ** given by the service provider in July.

2. The operation and maintenance cost of photovoltaic power station.

At present, the service life of photovoltaic power plants is about 25 years, and regular maintenance is required. In addition to providing installation and construction services, Zhejiang Carbon Silver provides annual operation and maintenance services of 200 yuan (different service providers), and the replacement of faulty devices is paid separately, calculated according to 25 years, and the operation and maintenance cost is more than 5,000 yuan.

You should understand that according to the market in 2020**, the cost is not high now.

It is estimated that by the end of 2020, the average construction cost of photovoltaic power plants will be about yuanw, and the cost of electricity at this time will be yuan.

1. National photovoltaic LCOE calculation.

In 2019, the average annual utilization hours of photovoltaic power in the country was 1,169 hours, and the construction cost of photovoltaic power stations was yuanw, and the cost of electricity at this time was yuan.

Note: The average price of desulfurized coal-fired electricity in China is: RMB. 】

According to the current trend of cost reduction, it is estimated that the average construction cost of photovoltaic power plants by the end of 2020 will be about yuanw, and the cost of electricity at this time will be yuan.

2. Calculation of the cost of electricity for different utilization hours.

The China Photovoltaic Industry Association's "China Photovoltaic Industry Development Roadmap" analyzes the LCOE of different utilization hours as follows:

In 2019, the LCOE of the equivalent utilization hours of ground-mounted photovoltaic power plants at 1800h, 1500h, 1200h, and 1000h under the full investment model were RMB kWh, respectively.

With the improvement of the efficiency of key equipment such as modules and inverters, the use of bifacial modules and tracking brackets, and the improvement of O&M capabilities, the price will be at the same price as the benchmark price of coal-fired power in most regions after 2021.

The specific cost needs to be determined in combination with the capacity of the system you build, and the system capacity needs to be considered in combination with the obstacles on the roof, the installation form of the photovoltaic system, and the load-bearing capacity of the steel structure.

1000 square meters of workshop, assuming that the actual utilization rate is 80%, tiling, about 80 100kwp photovoltaic system can be installed (assuming that there is no problem with the roof load-bearing), the cost, can be roughly estimated at 10 yuan wp (the specific needs to be determined according to the actual system configuration), then, the construction cost of this system is about 80 100w.

The power generated by the photovoltaic system can be converted into three-phase electricity and connected directly to the factory's switchboard, and the inverter has power output quality control, so there is no need for additional equipment such as voltage regulators.

At present, the country's distributed electricity price policy has not yet been issued, and some places have provincial and municipal subsidy policies.

How much does it cost to build a 1000 photovoltaic power station?

At present, the construction cost of the power station is about 10 yuan, so the call fee of 1MW power station should be about 10 million yuan.

Photovoltaic power station refers to a photovoltaic power generation system that uses solar energy and uses special materials such as crystalline silicon panels, inverters and other electronic components to connect to the power grid and transmit power to the power grid. Photovoltaic power station is the most encouraged green power development energy project by the state.

It can be divided into an independent power generation system with a battery and a grid-connected power generation system without a battery. Solar power generation is divided into solar thermal power generation and photovoltaic power generation. At present, solar power that has entered the commercialization refers to solar photovoltaic power generation.

Photovoltaic power generation products are mainly used in three aspects: first, to provide power supply for non-electric occasions; the second is solar daily electronic products, such as all kinds of solar chargers, solar street lamps and solar grass lamps; The third is grid-connected power generation, which has been widely promoted and implemented in developed countries.

By 2009, China's grid-connected power generation had not yet begun to be fully rolled out, but part of the electricity used for the 2008 Beijing Olympics was solar and wind power.

On December 4, 2013, the world's largest hydro-solar complementary photovoltaic power station located in the photovoltaic power generation park of Gonghe County, Qinghai Province - Longyangxia hydro-solar complementary 320 MW grid-connected photovoltaic power station officially started grid-connected operation, using water and light complementary power generation, from the power supply side to solve the problem of poor stability of photovoltaic power generation.

1MW = 1 million W, the current cost of ordinary ground-based power stations is about 12 W, plus the installation cost, the total average price is about 15 W.

You are not asking this question very specifically, so it is not good to give you a specific answer directly. Because a photovoltaic power plant involves many parts:1

The site required for the construction of the power station 2Photovoltaic solar modules 3Photovoltaic cable 4

Bracket 5Inverters These are essential parts of the construction of a photovoltaic power plant. At present, small power plants should be at least more than 1MW, and the investment amount can be calculated according to the total power of your specific installed photovoltaic modules, and the current construction cost of the power station is about 10 yuan, so the call fee of 1MW power station should be about 10 million yuan.

For you, this question is not good, and it will give you a specific answer directly. Because the investment cost of a photovoltaic power station involves many parts:1

Bracket 5Inverters These are essential parts of the construction of a photovoltaic power plant.

In general, the photovoltaic industry does not use the square to calculate many data of the photovoltaic power plant. Generally, it is calculated according to the installed capacity of the photovoltaic power station, and the amount of electricity generated per square hour can be determined according to the installed capacity.

Taking the commonly used monocrystalline silicon photovoltaic panels as an example, 100 square meters of roof can be installed about 10-13kw, if 10kw is installed, taking the light resource area in Zhejiang as an example, the annual power generation is about 10 * average power generation coefficient) = 11500 degrees.

The above calculations are taken as the lower threshold of the average value, and the actual power generation will be higher than this figure. From the above calculations, it can be seen that the annual effective light duration is 1500 hours. So we can draw the first conclusion that each square hour can generate about the degree of electricity.

Large-scale ground-mounted photovoltaic power station.

Since the adjustment of the subsidy for photovoltaic power plants, the cost of photovoltaic power generation has begun to decline, and the average of the current photovoltaic power station in the industry is Yuan W.

In fact, how much electricity can be generated per square meter per hour depends entirely on how much capacity photovoltaic power station can be installed per square meter.

From this, we can calculate the cost of each square meter of photovoltaic power station, taking 10kw as an example, the system price of the full package installation is about 50,000 yuan, and the installation of 10kw photovoltaic power station requires at least a roof area of about 70 square meters, so the cost of photovoltaic power station per square meter is about 50,000 70 = yuan.

Note: The cost required for different regions, different installation difficulties, different roofs, and different installation methods is slightly different. The above is a common installation method calculation.

One square can hold 200 to 220 watts, and one watt can generate about one kilowatt-hour of electricity a year.

**It will vary according to the installation conditions of the site, the brand of materials used, the construction method of the steel structure, the waterproof structure, the lightning protection system, and the later operation and maintenance charges. The Pearl River Delta is generally 5 to 6 pieces of a tile, and the north is lower. According to the current September 2022 brand module **, the power station with excellent quality will not be less than 4 yuan watts.

10 kilowatts,** will not be less than 40,000.

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.).
