What is Solar tracker

The tracker directs the solar panels or modules to the sun. These devices change their direction throughout the day to follow the path of the sun to maximize energy capture.steel omega profile manufacturers

Solar Tracker In photovoltaic systems, the tracker helps to minimize the angle of incidence between the incident light and the panel (the angle the light forms with the line perpendicular to the surface), which increases the energy produced by the device. Concentrated solar photovoltaic power and concentrated solar thermal energy have optics that directly accept sunlight, so the solar tracker must be properly angled to collect energy. All concentrated solar systems have trackers because the system does not generate energy unless it points to the sun correctly.

Solar energy is a renewable new energy source

As we continue to develop new energy industries, we are paying attention to the development and utilization of various new energy sources. Solar energy is a renewable new energy source. It is currently the most important type of new energy, and the photovoltaic support is also followed. Appeared and continuously developed, the photovoltaic support as its name suggests has played a certain supporting role, of course, this is not a simple bracket, but has a high technical, quality, material requirements.Steel Profile suppliers

The purpose of the photovoltaic bracket is to be able to support the fixing and placement of the position of the solar panel, so the material requirements are very important, so many aspects must be considered in the manufacturing process, such as whether it can resist outdoor changes. Whether the weather factor can still function normally in storms or blizzards, whether it can withstand the effects of thunder in thunderstorms, whether it can last for at least 30 years, etc. These are all manufactured. The problem that must be considered when the photovoltaic support is due to the large demand, the process of developing the photovoltaic support is very long, and it takes a lot of manpower and material resources.

Solar energy is a renewable new energy source

This also requires a number of factors to be considered in the use of photovoltaic supports, including the climatic factors to use the location of the photovoltaic support, whether it is rainy, snowy, cold weather, or hot weather, etc., which are necessary in the process of selecting and using. In consideration, only the choice of suitable, safe, and relatively strong, can guarantee the age. Furthermore, the installation of photovoltaic supports is also a problem. During the installation process, it is required to select the best position, which can adapt to different sunlight requirements and facilitate movement, so as to better function.

Before the PV rack is installed, there are many inspection processes and prepared professionals who should understand these issues when installing. First, there are many manufacturers of PV racks, they should choose the local soil environment, or It is a photovoltaic support for some environmental climates. When testing the test items, it is very good to test its appearance and its anti-corrosion coating. It should ensure that these coatings are in good condition and are designed in terms of model specifications and materials. When designing accessories, or some other equipment, it should be very complete, including bolts or some other materials,z profile steel ,according to the relevant provisions of steel structure construction, he will be able to achieve Relevant specification requirements.

The photovoltaic bracket should not be subjected to a forced blow during the installation process, which may cause certain damage to the entire equipment. During the installation of the bracket, its anti-corrosion layer should not be destroyed, because it will play a very important role in the later process. The role of the bracket angle setting, should pay attention to its angle, should be set in a reasonable position, so that it can be very good reception with the sun, the centerline deviation should also be within the specified range, and the vertical deviation The angle, or the whole field of the top level of the bracket should be set, which may bring better results in the later work process.

Moreover, during the process of on-site photovoltaic support construction, the installation of photovoltaic supports requires professional operators to operate. They may stand at the angle of these supports or their position and yaw angle calculations. Consider these issues from a more professional perspective, so you must be able to pay attention to these issues, and you should take some measures to ensure that the correctness of the process and sequence during the installation process is done in bracket installation or bolting. In the process, there are other aspects of the strength and related requirements.

Photovoltaic effect

“Photovoltaic effect”, Refers to the phenomenon that light causes a potential difference between different parts of the semiconductor or semiconductor to which the semiconductor is bonded. It is first the process of converting photons (light waves) into electrons and converting light energy into electrical energy; secondly, it is the process of forming voltage. With voltage, it is like building a dam. If the two are connected, a circuit of current will be formed.Steel Profile suppliers

Photovoltaic power generation is a technology that directly converts light energy into electrical energy by utilizing the photovoltaic effect of the semiconductor interface. The key component of this technology is the solar cell. The solar cells are packaged and protected in series to form a large-area solar cell module, and then combined with a power controller and the like to form a photovoltaic power generation device. The advantage of photovoltaic power generation is that it is less restricted by geographical area, because the sun shines on the earth; the photovoltaic system also has the advantages of safe and reliable, no noise, low pollution, no need to consume fuel and erecting transmission lines to generate electricity on site and short construction period. The photovoltaic effect is referred to as the photovoltaic effect, which refers to the phenomenon that light causes a potential difference between a heterogeneous semiconductor or a different portion of a semiconductor and a metal combination.

Photovoltaic effect refers to the phenomenon that light causes a potential difference between a heterogeneous semiconductor or a different portion where a semiconductor and a metal are combined. It is first the process of converting photons (light waves) into electrons and converting light energy into electrical energy; secondly, it is the process of forming voltage. With voltage, it is like building a dam. If the two are connected, a circuit of current will be formed.

When the P-N junction is illuminated, the intrinsic and extrinsic absorption of the photon by the sample will produce photogenerated carriers (electron-hole pairs). However, only the minority carriers excited by the intrinsic absorption can be caused by the photovoltaic effect. Due to the photogenerated holes generated in the P region, the photogenerated electrons generated in the N region are multi-sub States, and are blocked by the barrier and cannot be over-knotted. Only the photogenerated electrons of the P region and the photogenerated holes of the N region and the electron hole pairs (small children) of the junction region can drift over the junction under the built-in electric field when diffused to the vicinity of the junction electric field. The photogenerated electrons are pulled toward the N region, and the photogenerated holes are pulled toward the P region, that is, the electron hole pairs are separated by the built-in electric field. This results in the accumulation of photogenerated electrons near the boundary of the N region and the accumulation of photogenerated holes near the boundary of the P region. z profile

They produce a photogenerated electric field that is opposite to the direction of the built-in electric field of the thermally balanced P-N junction, with the direction from the P region to the N region. This electric field lowers the barrier, and the amount of decrease is the photo-generated potential difference. The P-terminal is positive and the N-terminal is negative. At this time, the Fermi level is separated, thereby generating a voltage drop, and electrodes are applied on both sides of the silicon wafer and connected to the voltmeter. For crystalline silicon solar cells, the typical value of the open circuit voltage is 0.5 to 0.6V. The more electron-hole pairs that are produced by the illumination at the interface layer, the greater the current. The more light energy absorbed by the interface layer, the larger the cell area of ​​the interface layer, and the greater the current formed in the solar cell.

The functions of solar photovoltaic support equipment steel should have

In the solar photovoltaic power generation system, the main characteristics of the photovoltaic support are not known. In the formation of the cost of all systems, solar photovoltaic brackets account for about 10% of the total system cost. The photovoltaic support equipment is a special support for the placement, installation and solid solar panel planning in the solar photovoltaic power generation system. The normal material is aluminum alloy and stainless steel.Steel Profile Manufacturers

The functions of solar photovoltaic support equipment steel should have

The photovoltaic support has strict requirements for steel functions, and the solar photovoltaic support equipment steel should have the following functions:

1.plasticity, toughness and fatigue resistance. A better press can cause a large deformation of the structure before it is damaged, so that people can invent and take compensation in real time. Better plasticity can also adjust the peak stress of the department. The self-solar solar panel device often adopts a forcing device for the adjustment angle, and the plastic machine can make the internal force redistribution of the structure, so that the stress of some inherent stress concentration parts in the structure or component tends to Uniform, progressively constructed group carrying capacity. A better tough machine can make the structure receive more energy when it is damaged under the external force impact load, especially the Gobi power station and the roof power station with large wind power, the wind vibration effect is remarkable, and the steel toughness can invalidate the damage level. Better fatigue resistance also enables the structure to have a stronger ability to withstand the repeated wind loads of the melon generation.

2.processing capabilities. Sophisticated processing machines include cold working, thermal processing and weldability. The steel used in photovoltaic steel construction is easy to process into various types of structures and components, and it is also necessary that these structures and components are not affected by the formation of strength, plasticity, toughness and excessive fatigue resistance.

3.tensile strength and yield point. The high yield point can reduce the section of the steel member, increase the weight of the structure, diligently divert the steel, and reduce the cost of the group name. The high tensile strength can increase the safety of the constructed group and improve the reliability of the structure.Omega Profile

4.the application life. Because the planned application life of solar photovoltaic systems is more than 20 years, the excellent anti-corrosion function is also the main indicator to balance the advantages and disadvantages of the bracket system. If the life of the stent is short, it will inevitably affect the stability of all structures, resulting in an extension of the investment recovery period and a decline in all target economic benefits.

5.Under the above premise, the steel for photovoltaic steel construction should also be easy to purchase and produce, although the price concessions are also very important.

 

Photovoltaic power generation is environmental protection or pollution

In recent years, China’s PV installed capacity has continued to expand and has become the world’s largest application market. However, at the same time of breakthroughs in development, z profile the problems of power cuts and overcapacity have become the bottleneck of industry development for many years. So is the current situation of abandoned light and power still still? What are the hardest hit areas that have abandoned light and electricity?

Photovoltaic power generation is environmental protection or pollution?

Photovoltaic power generation is environmental protection or pollution

Photovoltaic power generation “abandonment of light” means the amount of electricity generated by a photovoltaic power station, exceeding the maximum transmission capacity of the power system and the amount of power consumed by the load. Coexisting with the abandoned light is “limited power”, which limits the power output. The higher the light rejection rate, the lower the utilization rate of photovoltaic power generation. The reporter learned that in 2017, the average light rejection rate of the five northwestern provinces was 14.1%, far higher than the national average of 6%, while in 2015 and 2016, the figure exceeded 30%. Many PV companies in the Northwest region participate in the bidding transaction of the local power grid, and use the way of bidding below the market price to obtain the power transmission indicators to reduce the light rejection rate. The reporter learned that in 2015 and 2016, the newly installed PV installed capacity in the five northwestern provinces was 6.08 million kWh and 9.43 million kWh, accounting for 40% and 28% of the country. At this time, the construction speed of the power grid in the northwest region lags far behind the new installed capacity.

In addition, the laying of UHV lines is also costly. According to calculations, 100 kilometers of transmission lines are laid, and the investment cost needs to be 1.25 billion yuan. According to industry insiders, “abandonment of light” is mainly due to the limited transmission capacity of the power grid, which cannot be connected to the grid after the power station is built. The ability to absorb local energy in the northwest region is weak, and the power transmission capacity of the power grid has not kept up with the construction speed of photovoltaic power plants. Therefore, it is difficult to significantly change the phenomenon of “disposal of light”. The data shows that in 2017, the photovoltaic power generation in the northwest region was 39.286 billion kWh, an increase of 37.81% year-on-year, while the annual electricity consumption including delivery was only 7.79%.click

In fact, for photovoltaic power plants in the northwest, in addition to overcapacity and nowhere to transport, a key issue at present is that the local grid size does not have the capacity to support 10 million kilowatts of photovoltaic power. So, is there a way to turn photoelectricity into stable power to ensure its safe delivery? The reporter found that the “storage power station” may become the key to solving this problem.
