How to choose the material of solar racking |Antaisolar.com

 The right choice of solar racking material can impact the economic performance and stability of a solar power plant. So how to choose the right bracket according to the material? Generally, the main materials of solar racking are carbon steel, aluminum alloy. and new materials, carbon steel and aluminum alloy are widely used in the PV market.


The aluminum alloy made solar racking is aesthetically pleasing. Its main advantage is light-weight, which is one-third of the weight of carbon steel. The surface is highly corrosion-resistant, forming a dense oxide film protective layer in the air to further prevent oxidation. In addition, aluminum alloy still has a recovery rate of 65% after 25 years of the life cycle of the power station, which is environmentally friendly and recyclable. In terms of production and processing, aluminum profiles can be easily processed into various specifications through sawing, drilling, punching and other processes, making it more flexible and easy to install. Therefore, aluminum alloy solar racking is suitable for roofs with poor load-bearing or areas with severe salt damage and strong corrosion.


The carbon steel solar racking has high strength and high bearing capacity. Usually the surface is hot-dip galvanized, which can ensure a 25-year service life under normal conditions, but it needs regular maintenance. Therefore, when the strength requirements are relatively high and the actual span is relatively large, it is recommended to select steel solar racking when having a high strength requirements and large span.


Another new material is called as MAC steel, its coating layer is formed by high-temperature curing of zinc (Zn), aluminum (Al) and magnesium (Mg), so that the surface of MAC steel has a dense barrier that effectively prevents the penetration of corrosion factors. Compared with traditional hot-dip galvanized carbon steel , it performs a better corrosion resistance for large-scale solar ground projects.


With the popularization and application of solar plants, in order to cope with more severe corrosive environments and strict environmental protection requirements, how does a solar racking system provider react to such a complex natural environment? Focused on solar mounting system for over 15 years, Antaisolar attaches great importance to the combined optimization of materials and structure, it can offer the best solar racking solution based on different application scenario and provide well-suit material, covering aluminum alloy, carbon steel or MAC steel. The accumulated solar racking shipment by Antaisolar has reached 15GW and well operated worldwide. More projects in details please click at: https://www.antaisolar.com/projects_nc2

图片
  GeneralIntroduction: Antaisolar  standing seam roof mounting system  is an convenient and ideal solar roof solution. Made of anodized aluminum 6005-T6 and SUS 304, Klip lok 700 roof clamp enables less installation time and offers secure fastening and water tightness without penetrating the roof sheet. Here is the installation guide of Klip lok 700 roof clamp for your information. InstallationProcess: a. Fixing the Klip lok 700 roof clamp b. Fixing the earthing clip c. Placing the solar panels and use the end clamps to fix the panel d. Using the mid clamps to fix the panel e. Placing the entire panel from bottom to top f. Installing the grounding lug More installation details at  https://www.youtube.com/watch?v=OQr8xVhJE40 Installation precautions: Ø The bolts of the Klip lok 700 roof clamp are pre-assembled, and can be easily tightened after adjusting the clamp position. Ø The rubber pad at the bottom of the Klip lok 700 roof clamp needs to be fixed tightly to the metal roof surface.

  Can   solar panels   be mounted on a metal roof? For sure, metal roof is one of the best roof material to install solar panels, due to its durability and easy for installation. Either framed or frameless solar panels could be mounted, and the shadows of panels could keep your home cool during the summer. The Metal roof have various types. The corrugated steel roof is the basic type, which you can see everywhere. To fix solar panels on it, the solar mounting brackets need to penetrate the roof sheet and fix into the wooden or steel beam directly by screws or hanger bolts. Details as follow. 1.  L feet+self-tapping screws 2.  L feet+Solar hanger bolt L feet is widely used for its high adaptability, which do not have request on the size of metal roof sheet. For some project, below alu clamp will be developed to better adapt with the corrugated steel roof. But it is not proposed due to its unique adaptability.

A brief introduction to the earthing washer/grounding clips in solar mounting system

  Grounding PV modules  to reduce or eliminate shock and fire hazards is necessary and required by Electrical Code in countries in USA, Australia etc. The grounding guidelines of the Code es sentially state that all electrical equipment is to be grounded by means of direct attachment to an equipment grounding conductor. This can be done in many different ways. The traditional method is to use the ground bond point of each  solar panel  and connect all the panels together with heavy gauge bare copper wire. This approach can be difficult, time-consuming and costly. Some of the difficulties in grounding PV modules arise from the fact that copper conductors are typically used for electrical connections while the module frames are generally made of aluminum. The incompatibility of copper and aluminum was discovered from numerous fires in houses wired with aluminum wiring in the 1970’s. Copper and aluminum will also react and corrode. The surfaces of aluminum frames are anodized or have powd
