In the past ten years, solar energy has been rapidly developed and widely applied in the photovoltaic markets. With the increasing awareness of environmental protection, consumers' willingness to install photovoltaic products has gradually increased, which not only improves the environment, but also promotes the progress of photovoltaic technology. There is an urgent need to find a high-quality material that should be as light as possible, reduce the load on the building, ensure the beauty of the bracket,service life of up to 25 years and do not need to maintain the bracket frequently.Zinc Aluminum Magnesium steel is a good choice. The chemical composition of the Zinc Aluminum Magnesium steel is: 11% aluminum, 3% magnesium and the remaining all zinc. Due to the compound effect of these elements, the corrosion inhibition effect is further improved. In addition, it has excellent processing performance under severe conditions such as stretching,stamping,bending, painting,welding, etc.). It has a hard coating and excellent damage resistance performance.Compared with ordinary galvanized and aluminum-zinc coating products, it can achieve better corrosion resistance.And even if you use a hard tool to scratch or destroy the protective film on the surface of the steel,it’s self-healing property will solve this problem in a short time. Solar photovoltaic supports need to have a highly corrosion- resistant as it’s exposed to wind,rain and snow.Especially now that environmental problems such as acid rain and air pollution are becoming increasingly severe. The Zinc Aluminum Magnesium steel is composed of a dense alloy coating. It is the most precise and best coating material. Under the same coating, the service life of Zinc Aluminum Magnesium steel is 10-20 times that of galvanizing steel. It has a long service life, and the coating at the incision site has self-healing properties. It does not require post-dipping and post-processing procedures, which effectively guarantees the life of the bracket for more than 25 years. The advantage of using Zinc Aluminum Magnesium steel in the photovoltaic industry: 1.Good paint adhesion 2.Cutting edge self healing property 3.Scratch resistance 4.Rub resistance 5.Coating peel resistance

There are a lot of solar mounting racking in the market. Many customers will have questions when choosing. For example, what kind of photovoltaic bracket has better corrosion resistance? Is the bracket easy to install? Is the post maintenance cost high? On these questions, the Aluminum solar panel bracket can give a high score answer for the following reasons: From the appearance point of view, after anodizing treatment,the aluminum solar panel racking system surface will form a layer of oxide film, reduce the contact between air and bracket surface, so as to get the anti-corrosion effect. In addition to anodizing, the surface treatment methods of photovoltaic supports include spraying, frosting, etc. From the perspective of processing methods, the processing methods of aluminum solar mounting brackets are diversified, so its cross-section will be diversified, too. Aluminum racking can be produced by extrusion or bending. Extrusion is the original traditional production method, and now there are many new ways. The combination of various methods can accelerate the production speed and shorten the construction period. From the point of view of maintenance cost, the aluminum solar panel mounting brackets basically does not need to be maintained or painted in the later stage, so the maintenance cost is low. Personnel do not need to deliberate regular inspection, so the input of manpower, material resources and time would be less. From the perspective of the installation method, the aluminum solar mounting system solutions adopts the installation method of accessories connection, does not need to punch,and is easy to assembly and dismantle. And the connection mode is various,customer can choose the internal connection mode or the external connection mode. From the perspective of stability, although the aluminum solar panel mounting is connected with accessories, it has high connection strength, is not affected by the environment, and has a long service time and good stability.

1. Cement/concrete roof Cement is usually used as the foundation of solar panel mounting systems on flat roof. The production of general cement foundation requires accurate statistics of the annual average wind speed and wind direction in different seasons of the project site, and calculate the positive and negative wind pressure. Then the counterweight of cement foundation is calculated by wind pressure. Cement briquettes with the same size are pre-processed and then transported to the site for installation. Corigy Solar can not only design the flat roof solar racking according to the various conditions provided by customers, but also provide the service of calculating the weight of cement block. The accurate calculation of solar mounting system solutions can design a stable solar panel mounting brackets at the most cost-effective condition. 2. Metal/Tin roof Metal/Tin roof is generally used in light steel structure buildings, which are often seen in standardized workshops and warehouses. The material used for the roof is steel sheet formed by cold pressing or cold rolling.Generally, it uses snap, buckle, lock and other non penetrating for installation.The use of clamps will not cause roof leakage or damage to the overall structure. Corigy Solar has various clamps, suitable for most metal roof solar mounting systems, and we can also provide customized services to produce the clamps you need. 3. Tile roof structure Tile roof is commonly seen in civil buildings. For the tile inclined roof, the installation method is generally to uncover the tiles, install special hooks below, and then cover the tiles back. Corigy Solar has rich types of popular hooks on the market, which meets the installation requirements of most tile roofs.Moreover,the installation design is beautiful and simple, and does not affect the structure of the roof.

At present, the main materials of solar panel racking system are Aluminum Alloy (AL6005-T5 surface anodized), Stainless Steel (SUS304), Galvanized Carbon Steel (Q235 hot-dip galvanized). Among them, stainless steel is the best, which has the advantages of high strength, corrosion resistance, and high recycling value. But correspondingly, the cost of stainless steel is the highest among the three materials. The appropriate choice is aluminum alloy. Aluminum alloy racking system for solar is widely used in the solar roof racking and solar ground mount structures, it has the characteristics of corrosion resistance, light weight, beautiful and durable. It is worth mentioning that aluminum alloy solar panel mounting brackets basically does not need maintain in the later stage, and it has high recovery value, with relatively small installation cost to achieve the maximum use effect. The last is galvanized steel solar panel mounting, which has the advantages of the low cost, stable performance and high bearing capacity. However, the later maintenance cost is very high. Because the anti-corrosion performance of the steel PV mount system is not high, when the zinc layer on the surface of the steel support falls off, it will be corroded quickly and become very fragile. Therefore, the protection of the zinc layer on the surface of the hot-dip galvanized steel solar structure is the most important thing in the later maintenance. Moreover, the recovery value of carbon steel bracket is the lowest of the three materials. There are long and short cost recovery periods for photovoltaic projects. Generally speaking, the cost can be recovered within 5-7 years. However, the average life expectancy of most solar panel racking system falls between 25 and 30 years. The remaining life of photovoltaic system determines the profit. Therefore, it is very important to choose a suitable mounting bracket. You must take the maintenance cost and recovery value into consideration. Corigy focuses on the design and manufacture of solar panel support, and will design the most suitable solar mounting solutions for customers by comprehensively considering the factors such as land, climate and environmental conditions of the installation site, and choosing the materials suitable andeconomical.

The Chinese court charged with appointing an administrator to restructure solar manufacturer Yingli has decided to package the six Yingli companies concerned into one administration, according to a document filed with the U.S. Securities and Exchange Commission (SEC) today. Yingli Energy (China) Co. Ltd; Baoding Tianwei Yingli New Energy Resources Co. Ltd; and Yingli China subsidiaries Hainan Yingli New Energy Resources Co. Ltd; Tianjin Yingli New Energy Resources Co. Ltd; Hengshui Yingli New Energy Resources Co. Ltd; and Lixian Yingli New Energy Resources Co. Ltd will be treated as one package by the administrator appointed by the Baoding Municipal Intermediate People’s Court in Hebei province. Announcing the court had agreed to demands from Yingli creditors to appoint an administrator last month, Yingli said the core contents of its restructuring plan were “the conversion of a significant portion of the financial debts of Yingli’s major PRC subsidiaries into controlling equity interests in the subsidiaries, full and orderly repayment of parts of financial debts and other payables, and fund injection [from] third-party platforms,” hinting at the break-up of the business. The SEC filing published today by the OTC Markets Group-listed company, stated: “Yingli Green Energy, the ultimate parent company of those six companies, cannot assure that any proposed debt restructuring plan will leave any value for its shareholders and will further update the market when there is significant new progress.”
