How much does it cost to build a one megawatt solar power plant, how many kilowatts of electricity c

Build a oneMWThe solar power station costs about 10 yuan. How many kilowatt-hours of electricity can be generated per year: 120 kilowatt-hours of electricity.

If photovoltaic power plants.

The efficiency of the system is within a reasonable range, taking Beijing as an example: if the annual utilization of each kilowatt is about 1200 hours, the actual annual power generation of 1MW is about 1200H * 1000kW = 1.2 million kWh.

Example. Shanghai Shenergy invested 65 million yuan to build a 1 megawatt solar power plant. For a 1 megawatt power station, the theoretical value of one hour of power generation is 1000 kWh, and the power generation is counted as 6 hours per day. 6000x365=2190000 kWh.

At present, the cost of the general photovoltaic power station system in China is about 10 yuan.

If the efficiency of the photovoltaic power station system is within a reasonable range, taking Beijing as an example: the annual utilization per kilowatt is about 1200 hours, then the actual annual power generation of 1MW is about 1200H*1000kW=1.2 million kWh.

The cost of power stations includes land costs, equipment costs, engineering costs, etc., and the price of megawatt power stations varies according to different regions, and other people's projects may not be suitable for you. Think about it another way, how much money are you prepared to pay, and then you design the power station. Just like buying a car, instead of asking others how much it costs to buy a Mercedes-Benz, it is better to ask you if you have 500,000 yuan and what cost-effective car you recommend...

10,000 square meters, with an annual power generation of 1,708,900 kWh and an average daily power generation of 349 kWh.

Generally, 250w solar photovoltaic panels, the area is, that is, 250, 1 acre of land is converted into meters, 300, if tiled, it is:

200001, of course, it is impossible to install tiling, to leave 20% of the maintenance space, then it is 200001, if calculated according to the sunshine time in the northwest desert area, there can be an average of 6 hours of effective sunshine per day.

The annual power generation is almost 24436 6 365 = 53514840 kWh, and the annual income is 53514840 yuan according to the grid parity.

The cost of photovoltaic construction is about 3 yuan w, and the investment 24436922 3 = 73310766 yuan, if the operating cost is not counted, the cost will be recovered in 3 to 4 years, of course, the operating cost is impossible to ignore, in fact, it will take almost 10 years to recover the cost, and the next 10 years is the net profit of 20 million yuan.

This is only theoretical, and the actual situation needs to be negotiated with the local **.

10,000 mu = 6,666,600 square meters, a large solar panel of normal specifications is 2 square meters, 6,666,600 2 = 3,333,300, a board is 330wp per hour full power generation, 3333300 * 330 = 1099989000wp, that is, you spread 10,000 acres of solar energy, full power generation per hour 1099989 kilowatt-hour electricity, my brother's project is very large.

If it is a small power station and a household photovoltaic power station, it includes 4-6 yuan w of equipment in the southern region, and does not include yuan w of equipment. If it is a large-scale power station of more than 1MW, the color steel tile roof is in Yuan W, and the cement roof is Yuan W.

Photovoltaic power station is mainly a photovoltaic power generation system, including various buildings 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.

Main power devices of photovoltaic power stations:

The choice of the main power components of the inverter power supply is very important, at present, the most used power components are Darlington power transistors, power MOSFETs, insulated gate transistors and turn-off thyristors, etc., and the devices used more in small capacity and low voltage systems are MOSFETs, because MOSFETs have a lower on-state voltage drop and a higher switching frequency.

IGBT modules are generally used in high-voltage and large-capacity systems, because the on-state resistance of MOSFETs increases with the increase of voltage, and IGBTs have a greater advantage in medium-capacity systems, while GTO is generally used as a power component in ultra-large-capacity systems.

The manual installation cost of power station installation varies from place to place, and is generally calculated in yuan per watt.

Now the cost of photovoltaic power plants is relatively cheap.

Taking the 5kw photovoltaic power station as an example, the total investment cost in the early stage is about 2-30,000 yuan, and now the terminal cost of the photovoltaic power station is about yuan per watt, and now the installation has the income from selling electricity, and the home can also use electricity for free during the day, and the annual comprehensive rate of return is about 13%, and the cost can be recovered in about a year.

Carbon silver photovoltaic power station.

Installed photovoltaic power station.

Answer: Photovoltaic installation, generally calculated by watts, pure manual installation is generally yuan watts. For example, 10kw system, the installation fee is about 2000 yuan-2500 yuan, must be replaced by square meters, you can calculate it like this, 10kw plane terrain, generally covers an area of 100 square meters, that is, 20 yuan-25 yuan square meters, for reference only, the specific local shall prevail.

At present, the cost is around 10 yuan per watt, and the module is currently at 10 yuan per watt.

I have a professional photovoltaic construction team, and the installation bracket and photovoltaic panels are one watt to one yuan, according to the terrain and the height of the bracket 9 to 150,000 megawatts.

The construction site is different, and the pure cleaning package is every tile.

How much does it cost to install a megawatt.

It depends on what to do with the roof or the reservoir.

Where is your construction team? Leave a QQ or **. There is an existing 25MW project on hand.

How much is a watt installed with photovoltaic panels.

About 200,000, depending on the specific situation.

There is a 20 mega photovoltaic piling according to the installation, does anyone do it, please**.

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.

700 million yuan. 1. There is no danger of resource depletion.

2. The power generation process is safe and reliable, and the danger is very low; There is no noise, no pollution and no pollution in power generation.

3. The power generation site is not limited by the geographical distribution of resources, as long as the sun can be obtained. At the same time, in some areas where there is no electricity or the terrain is complicated, the roof of the building can also be used to generate electricity.

Main advantages: local power generation and power supply can be generated without the need to lay transmission lines; The construction period is short, and the time and materials spent on obtaining energy are relatively small. The income is high, the power generation is used for its own use, the electricity bill is saved, and the excess electricity is sold to the state to obtain additional income.

Small-scale household power stations are about 10 yuan per watt, and you are so big that it is cheaper to 7 yuan per watt, so 100 megawatts = 100,000,000 watts, ** is 100,000,000 * 7 = 700 million yuan

The details are as follows: 8.5 million steam turbine generator sets; boilers 15.5 million; The control system has 6 million high and low voltage cabinets and DCS (including DC chimney and UPS Siemens configuration); 550,000 thermal automation instruments; boiler auxiliary equipment (water circulation, dosing, deaeration equipment, ash removal and coal transportation, pump) 9.7 million; 1.2 million cooling hydraulic systems (chilled water towers, condensers, water injection tanks, soft water treatment, chemical water tests); pipes, supports and chimneys and systems insulated 5.5 million; The overall system installation and commissioning fee (including thermal insulation partition) is about 4.5 million; The civil construction cost is 5.5 million. This does not include labor costs and maintenance costs.
