The main photovoltaic equipment at this stage**:

Components: First-line brands can buy about yuan watts if they buy more than MW, and if they get the goods below MW, it will be slightly more expensive by 5 cents to 1 cent.

Inverter: The first-line brand of string inverter ** is about 3 to 3 5 per watt, and the second-line brand is about 2 cents lower; The **2 gross 1-2 gross 3 of the centralized inverter is relatively common**.

Other brackets, cables, box transformers, high and low voltage cabinets, etc., add up to about 1 piece of 5 watts.

Photovoltaic Installation**Order: Hello! Glad for your question.

Photovoltaic installation is generally calculated according to watts, and pure manual installation is generally yuan watts. For example, 10kw system, the installation of only lead fee is about 2000 yuan - 2500 yuan, must be replaced by square meters, you can calculate it this way, 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. It can also be determined according to the installed capacity, the large megawatt pure labor cost is about yuan, and the small distributed pure labor cost will be more expensive, right.

Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photogenerated volt effect at the semiconductor interface. It is mainly composed of three parts: solar panels (components), controllers and inverter slag generators, and the main components are composed of electronic components. 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.

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. Because the photovoltaic power station is mainly based on the photovoltaic power generation Huishan quiet system, including all kinds of buildings and auxiliary facilities such as maintenance, 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.

The photovoltaic installation ** list and mask table is between 4-10,000.

First of all, according to the terminal market of the photovoltaic power station used by oneself, the first is yuan, according to the block, if the installation of 10kw is 10,000 yuan, the investment is 10,000 yuan, as well as the bracket fee, the line and other consumables, the installation cost between the yuan, and the distributed household cost are added between 40,000 yuan, if you understand photovoltaic, electrical, structure, etc., you can control it within 40,000 yuan to find workers.

In the past two years, there have been few photovoltaic subsidies, and there are local subsidies in different regions, so you can check it out.

Precautions for Installing PV:

Under the condition of light, the photovoltaic power generation system will generate direct current, and the current will increase with the increase of light, and if it touches the electronic circuit of the module, it will be at risk of electric shock or burns, which may be fatal.

In the process of installation and maintenance, first of all, cut off the power supply of the photovoltaic power generation system, or cover the surface of the module with opaque materials.

To avoid the risk of arcing and electric shock, do not disconnect the electrical connection when working with a hood state load, be sure to keep the plug dry and clean, make sure it is in good working order, and do not insert other metal objects into the plug or use any other means to make the electrical connection.

A 10 kW system of household photovoltaic power generation** is about 100,000.

From a national perspective, the cost of solar photovoltaic power generation is 8-12 yuan per watt. For example, a 100-square-meter roof can be made of 10 kilowatts, according to 10 yuan per tile, and the final total contract is 100,000 yuan. This ** includes design, equipment, construction and grid connection.

The specific ** still needs to be determined in combination with demand and installed capacity.

Photovoltaic power generation equipment is different from different materials, there are single forehand closed crystalline silicon and polysilicon, the two are different, monocrystalline silicon is better than polysilicon, and the power generation efficiency is higher.

Advantages of photovoltaic power generation:

1. Solar energy resources are inexhaustible, and the solar energy that irradiates the earth is 6,000 times greater than the energy currently consumed by human beings. Moreover, solar energy is widely distributed on the earth, and photovoltaic power generation systems can be used wherever there is sunlight, regardless of region, altitude and other factors.

2. Solar energy resources are available everywhere, and they can be supplied nearby, without long-distance transmission, which avoids the loss of power caused by long-distance transmission lines.

3. The energy conversion process of photovoltaic power generation is a direct conversion from light energy to electrical energy, without intermediate processes (such as thermal energy to mechanical energy, mechanical energy to electromagnetic energy, etc.) and mechanical movement, and there is no mechanical wear. According to the thermodynamic analysis, photovoltaic power generation has a high theoretical power generation efficiency, which can reach more than 80, and the technology development potential is huge.

4. Photovoltaic power generation itself does not use fuel, does not emit any cracking substances including greenhouse gases and other exhaust gases, does not pollute the air, does not produce noise, is environmentally friendly, and will not suffer from the impact of energy crisis or fuel market instability, and is a new renewable energy source that is truly green and environmentally friendly.

5. The photovoltaic power generation process does not require cooling water, and can be installed on the desert Gobi without water. Photovoltaic power generation can also be easily combined with buildings to form a photovoltaic building integrated power generation system, which does not need to occupy a separate area and can save valuable land resources. <>
