Advantages: Can quickly receive solar energy resources. Advantages: Close proximity to existing electrical systems, helping to reduce overall costs. Advantages: Daily electricity production increases or decreases depending on the intensity of sunlight, saving more energy. Disadvantages: The square orientation of the power generation panel is primarily architectural. Disadvantages: Because they are close to the roof, photovoltaic modules operate at a higher temperature. Disadvantages: When the roof needs to be renovated, the square matrix must also be removed. Disadvantages: The size of the square board is limited by the available surface area.
1. What is the principle of solar panels?
1. A solar cell is a device that responds to light and can convert light energy into electrical energy. There are many types of materials that cannt produce photovoltaic effects, such as monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, selenium, indium, copper, etc. Their principles of electricity production are basically the same. Now let's take the example of crystalline silicon to describe the photovoltaic energy production process. Crystalline P-type silicon can be doped with phosphorus to obtain N-type silicon, forming a P-N junction.
2. When light shines on the surface of the solar cell, some photons are absorbed by the silicon material; energy from the photons is transferred to the silicon atoms, causing electrons to jump and collect free electrons. on both sides of the P-N junction, forming a potential difference. When the external circuit is activated, under the action of this voltage, a current will flow through the external circuit, producing a certain thenexit session. The essence of this process is the process of converting photon energy into electrical energy.
2. How many types of solar power generation are there?
1. Light-heat-electricity conversion mode, using thermal energy generated by solar radiation to produce electricity. Generally, the absorbed thermal energy is converted by a solar collector.
Replace it with active steam, then drive the steam turbine to produce electricity. The first process is a photothermal conversion process; the second process is a thermoelectric conversion process, which is the same as ordinary thermal power generation. The disadvantages of solar thermal energy production are low efficiency and high cost. Its investment is estimated to be at least 5 to 10 times more expensive than that of ordinary thermal power plants. A solar thermal power plantof 1,000 MW requires an investment of $2-2.5 billion, and the average investment for 1 kW is $2,000-2,500. Therefore, it is suitable for special occasions on a small scale but is economically exploitable on a large scale.
2. Direct photoelectric conversion uses the photoelectric effect to directly convert solar radiation energy into electrical energy. The basic device for photoelectric conversion is the solar cell. A solar cell is a device that uses the photovoltaic effect to directly convert solar energy into electrical energy. It is a semiconductor photodiode. When sunlight hits a photodiode, it converts solar energy into electrical energy, producing an electric current. When many batteries are connected in series or parallel, it can become a solar cell array with relatively high power output.important.
Three. What are the advantages and disadvantages of solar panels?
1. Advantages:
(1) It is generally easy to receive solar energy resources.
(2) Installing photovoltaic squares on the roof allows you to use otherwise unnecessary space and save yard space.
(3) Close to the existing electrical system, helping to reduce overall costs.
(4) Roof-mounted equipment has minimal impact on the site.
2.Disadvantages:
(1) The direction of the square network is mainly that of the buildings.
(2) Because they are close to the roof, photovoltaic modules operate at a higher temperature (so the efficiency is lower).
(3) The number of square tables is limited by the available surface area.
(4) When the roof needs to be renovated, the square matrix must also be removed (the roof was in good condition at the beginning,this will therefore only happen 15 years later).
(5) The square board may not be easily accessible. In this case, the ice and snow on the square matrix cannot be removed.
(6) Penetration into the roof (drilling holes are required when attaching the square array to the roof) may cause the roof to leak.
A share capital of 500,000 is sufficient. Why do you want to produce it yourself since you are positioning systems integration, unless you have deep pockets and can manufacture all your products yourself? require integrated treatment. Hire 1 engineer and 2 electricians. It only takes 5 to 6 small workers to procure all the equipment from the manufacturer and integrate it. Or if you have a project, our company can integrate it for you. You just need to tell me the size of system you need. This way you just need to hire peopleel commercial to execute the project. eh eh !
