The process of solar cell PV module production line

Suitable for any type of panel that derives energy from the sun: photovoltaic, solar hot water, especially photovoltaic pump systems. Suppose the panel is fixed or has a slope that can be adjusted seasonally. Panels that track the entire solar motion can get 10% (winter) to 40% (summer) more energy than fixed panels. If you are in the northern hemisphere, solar panels should always face the true south, and if you are in the southern hemisphere, the solar panels should be truly south. z purlin manufacturers. If you use the compass orientation panel, you need to correct the different differences, depending on the location. Search for “magnetic declination” on the network to find the correct angle for your location.

It is easiest to mount the solar panel in a fixed, tilted position. However, due to the high summer sun and low winter, the slope of the panel can be adjusted according to the season, and more energy can be captured throughout the year. In short, adjusting the tilt twice a year can effectively increase energy. Adjusting it four times a year can only be a little more, but if you need to optimize production in the spring and fall, it can be important.

If the solar panel will have a fixed angle of inclination, and get the most energy throughout the year. Fixed angles are convenient, but have some drawbacks. As mentioned above, the PV pump system will achieve less power than the adjustment angle. Also, if you live in a place with snow, adjust the panel to a steeper angle in winter. Snow-covered panels produce little or no power.

The process of solar cell PV module production line:

The component line is also called the package line. The package is a key step in the production of solar cells. Without a good packaging process, a good battery can not produce a good component board. The battery package not only ensures the battery life, but also enhances the battery’s impact strength. The high quality and longevity of the product is the key to winning customer satisfaction, so the package quality of the component board is very important.

Process: battery testing – front welding – inspection – back series – inspection – laying (glass cleaning, material cutting, glass pretreatment, laying) – lamination – deburring (de-edge, cleaning) – frame ( Gluing, cornering, punching, framed, scrubbing glue) – welding junction box – high voltage test – component test – visual inspection – packaging into the warehouse.

How to ensure high efficiency and long life of PV modules: high conversion efficiency, high quality battery; high quality raw materials, such as: high cross-linking EVA, high bond strength encapsulant (neutral silicone resin), High transmittance, high strength tempered glass, etc.; reasonable packaging process; rigorous work style of employees. Because solar cells are high-tech products, some details in the production process, some inconspicuous problems such as wearing gloves should not wear, should be evenly painted reagents, and smashing things are the enemy of product quality, so in addition to the development In addition to reasonable production processes, the seriousness and rigor of the employees is very important.

Alloy steel pipe

The main purpose of alloy steel pipe is used in high-pressure high-temperature pipelines and equipment such as power plants, nuclear power, high-pressure boilers, high-temperature superheaters and reheaters. It is made of high-quality carbon steel, alloy structural steel and stainless steel. It is formed by hot rolling (extrusion, expansion) or cold rolling (drawing).

Alloy pipe is a kind of seamless steel pipe. The alloy pipe is divided into structural seamless pipe and high pressure heat resistant alloy pipe. Mainly different from the production standard of alloy tube and its industry, the alloy tube is annealed and quenched to change its mechanical properties. Achieve the required processing conditions. The performance of the seamless steel pipe is higher than that of the general seamless steel pipe. The chemical composition of the alloy pipe contains more Cr, high temperature resistance, low temperature resistance and corrosion resistance. The carbon seamless pipe contains no alloy composition or few alloy components. The reason why the alloy pipe is widely used in petroleum, aerospace, chemical, electric power, boiler, military and other industries is because the mechanical properties of the alloy pipe are changed and adjusted.

The alloy pipe is defined by the production material (that is, the material). As the name suggests, it is the pipe made of alloy; and the seamless pipe is defined by the production process (seam seamless), which is different from the seamless pipe. There are seam pipes, including straight seam welded pipes and spiral welded pipes.seamless pipe suppliers

The alloy tube has a hollow section and is used as a conduit for transporting fluids, such as oil, natural gas, gas, water, mechanical processing, and some solid materials. Compared with solid steel such as round steel, alloy steel pipe has light weight when the bending and torsional strength are the same. Alloy steel pipe is an economical section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe and automobile transmission. Shafts, bicycle frames, and steel scaffolding used in construction.

The use of alloy steel pipe to manufacture ring parts can improve the material utilization rate, simplify the manufacturing process, save materials and processing man-hours, such as rolling bearing rings, jack sleeves, etc., and have been widely used in steel pipes. Alloy steel pipes are also indispensable materials for various conventional weapons, and barrels, barrels, etc. are all made of steel pipes. Alloy steel pipes can be divided into round pipes and shaped pipes according to the shape of the cross-sectional area. Since the area of ​​the circle is the largest under the condition of equal circumference, more fluid can be transported by the circular tube. In addition, the circular section is subjected to a relatively uniform force when subjected to internal or external radial pressure, and therefore, most of the steel pipes are round pipes.

Alloy tubes are large-diameter alloy tubes, thick-walled alloy tubes, high-pressure alloy tubes, alloy flanges, alloy elbows, P91 alloy tubes and seamless tubes, and special fertilizer tubes are also very common.

Quality issues that PV modules often encounter

Photovoltaic modules produce electricity when illuminated or illuminated by other sources. Take appropriate precautions when handling, to avoid direct contact with people with 30V DC or higher. Solar photovoltaic modules convert light energy into DC power, and the amount of electricity varies with light intensity.

Let’s take a look at the quality issues that PV modules often encounter:

1.Power attenuation classification and detection method:

Quality issues that PV modules often encounter

PV module power attenuation refers to the phenomenon that the output power of the component gradually decreases as the illumination time increases. The power attenuation of photovoltaic modules can be roughly divided into three categories: the first category,z profile component power attenuation due to destructive factors; the second category, the initial photoinduced attenuation of components; the third category, the aging attenuation of components. Among them, the first type is the controllable attenuation during the installation of photovoltaic modules. For example, strengthening the unloading, reversing, and installation quality control of photovoltaic modules can reduce the probability of cracking and chipping of component cells. The second and third categories are the technical problems that need to be solved in the production process of photovoltaic modules. PV module power attenuation testing can be done with the PV module I-V characteristic tester.

2.Hot spot formation causes and detection methods:

The hot spot of the photovoltaic module means that the component is not exposed to sunlight due to the sunlight, so that the covered part heats up much more than the uncovered part, causing the burnt dark spot to be overheated. The formation of hot spots of photovoltaic modules is mainly composed of two intrinsic factors, namely internal resistance and dark current of the cell itself. The hot spot endurance test is a test for determining the ability of a solar cell module to withstand hot spot heating effects. The solar cell module is tested by a reasonable time and process to indicate that the solar cell can be used for a long period of time under specified conditions. Hot spot detection can be detected by an infrared camera. The infrared camera can use thermal imaging technology to display the measured target temperature and its distribution in a visible heat map.

3.Causes of crack formation and detection methods:

The crack is a small crack in the battery. The crack of the battery will accelerate the power attenuation of the battery and affect the normal service life of the component. At the same time, the crack of the battery will expand under the mechanical load, which may cause open circuit damage. Cracking can also cause hot spot effects.

A square cylinder type

The square cylinder is a square cylinder type, which is isolated into a basic square cylinder, an enhancing square cylinder, a structure square cylinder, a mechanical square cylinder, and so on as per the reason, and is generally utilized in building development, so which is the shaping procedure of the square tube,two sorts of welding, first framing: the welding funnel is first welded into a circle, and afterward transformed into a square tube.square steel tubing available to be purchased, The upside of this strategy is that it lessens the handling of the rolls and it is increasingly advantageous to change the assortment.steel coil manufacturers Structure first. Post-welding: Square cylinders are shaped straightforwardly and afterward welded. The favorable position is that the quantity of square cylinder shaping edges keeps on expanding with the improvement of the item. The heap on which the parts are distorted is adjusted, and the burden is that the utilization of the rolls is expanded.

What is the reasonable setting and stockroom about square cylinder

A square cylinder type

It is critical to pick the correct setting and stockroom for the square cylinder. So what is the reasonable setting and distribution center? (1) The site or distribution center where the steel pipe is to be put away will be chosen in a perfect and well-emptied place away out of the plants and mines that produce hurtful gases or residue. Weeds and a wide range of trash ought to be expelled on the site to keep the steel pipe clean; (2) The distribution center ought to be chosen by topographical conditions, for the most part embracing common shut stockrooms, that is, distribution centers with dividers, entryways and windows, and ventilation offices; (3) The distribution center needs to focus on ventilation on radiant days, focus on close the dampness verification in stormy days, and consistently keep up an appropriate stockpiling condition; (4) Do not stack together materials that are destructive to steel pipes, for example, corrosive, soluble base, salt and concrete in the distribution center. Various kinds of steel funnels ought to be stacked independently to counteract perplexity and avoid contact erosion; (5) Large-sized steel, steel rails, mortifying steel plates, enormous breadth steel channels, forgings, and so on can be stacked in the outdoors; (6) little and medium-sized steel, wire pole, steel bars, medium bore Steel funnels, steel wires and steel wire ropes, and so forth., can be put away in a well-ventilated shed, yet should be set on the underside; (7) some little steel channels, dainty steel plates, steel strips, silicon steel sheets, little measurement or meager walled steel funnels, different virus Rolled and cold drawn steel channels and extravagant, destructive metal items can be put away.

As of late, with the improvement of the economy, the interest for square cylinders has likewise expanded. The square cylinder makers are in accordance with the necessities of the advancement of the occasions. The measure of square cylinder discount is likewise enormous 4 square tubing. The creation excitement of the square cylinder production line kept on being high, particularly the huge scale square cylinder makers’ working rate bounced back altogether, and the weight on the business’ asset supply was additionally expanded. On one side, the square cylinder industrial facility has a high creation eagerness and supply weight keeps on expanding.

In the subsequent perspective, downstream cylinder the board request is still delayed to discharge. In spite of the fact that the full scale level has been consistently improved, the assembling business has kept on improving, and the fare the executives has arrived at a record abnormal state, viably lightening local supply weight.

Common forms of photovoltaic supports

One of the most important features of any type of solar photovoltaic component assembly component is weatherability. It must be ensured that the structure must be robust and reliable for 25 years, such as environmental erosion, wind and snow loads and other external effects. Safe and reliable installation, maximum installation efficiency, almost maintenance-free, reliable maintenance, and recyclability with minimal installation costs are important factors to consider when making alternatives. At present, some photovoltaic bracket enterprises apply high wear-resistant materials to resist wind and snow loads and other corrosive effects, and comprehensively utilize aluminum alloy anodizing, ultra-thick hot-dip galvanizing, stainless steel, anti-UV aging and other technical processes to ensure solar energy support and solar energy. Track the service life.

Common forms of photovoltaic supports

Photovoltaic stents are available in a variety of classifications, such as welding and assembly according to the connection method. They are divided into fixed and daily depending on the installation structure, z profile steel manufacturer,and are divided into ground and roof according to the installation location. Regardless of the type of photovoltaic system, the brackets are generally similar, including connectors, columns, keels, beams, and auxiliary parts.

Fixed PV bracket refers to the bracket system whose orientation, angle, etc. remain unchanged after installation. The fixed installation method directly places the solar photovoltaic modules toward low latitudes (at an angle to the ground), and forms a solar photovoltaic array in series and parallel to achieve the purpose of solar photovoltaic power generation. There are various fixing methods. For example, the ground fixing method includes pile foundation method (direct embedding method), concrete block weight method, pre-buried method, ground anchor method, etc. The roof fixing method has different schemes depending on the roofing material. .

Photovoltaic stents for solar arrays are typically secured by steel hot dip galvanized workpieces or stainless steel anchor bolts that extend from the reinforced concrete foundation. Where a concrete foundation is used on the roof of the house, the waterproof layer of the house is uncovered and the concrete surface is peeled off. The reinforcing bars of the concrete blocks for the array are welded together on the steel bars of the patio. When the steel bar cannot be welded, in order to resist the wind pressure by the adhesion of the concrete and the self-weight, the surface of the concrete base is uneven and the adhesion is increased. Thereafter, a secondary waterproofing treatment is performed with a water-repellent filler.

If the above method cannot be carried out, a weather-resistant cushioning material such as a relatively expensive silica gel may be applied to the waterproof layer, and a heavy-weight steel skeleton of hot-dip galvanizing may be attached thereto, and then the array holder may be fixed on the steel skeleton. The steel skeleton is connected by plastic bolts to the protruding wall around the room. The aim is that the wind pressure does not move the array and the steel skeleton. Provides auxiliary reinforcement.
