Regarding solar mounting system, which is better for aluminum or stainless steel?

Data:2018-11-08

As we know, solar mounting system are equivalent to the "backbone" in photovoltaic power generation system. It's performance and service life are directly related to the benefits of solar energy systems. Generally, the brackets on the market can be roughly divided into two types of materials: aluminum solar mounting bracket and stainless steel solar bracket. For many users who are entangled in the choice of materials, CHIKO Solar shares some experience for everyone.
Regarding solar mounting system, which is better for aluminum or stainless steel?
First of all, solar mounting system are generally used outdoors, long-term exposure to wind and sun, should consider the two aspects of anti-corrosion and rust and firmness.
 
1. In terms of strength analysis, the strength of aluminum solar mounting bracket is weaker than that of stainless steel. Therefore, it is recommended to use steel brackets for strength in areas with high wind resistance requirements or in practical applications. The need for aluminum brackets is mostly used in general areas.
 
2. From the perspective of anti-corrosion performance, because the anti-corrosion quality not only affects the service life of the photovoltaic power station, but also affects the appearance of the bracket. Generally, the surface of the stainless steel photovoltaic support is hot-dip galvanized, generally required to be 65μ or more. Under normal conditions, the service life of 20 years can be ensured, but regular maintenance is required, and the surface of the aluminum alloy support is anodized to form a dense oxide film and anti-corrosion performance. It is far superior to steel brackets, and the surface aesthetics of aluminum alloy solar bracket are also superior to steel brackets.
 
3. From the price of the two, if the strength requirement is relatively high, if the aluminum solar mounting bracket must be used, the material can only meet the requirements by increasing the material, and the price of the aluminum alloy on the market is about the steel bracket. 3 times, therefore, the cost of aluminum alloy photovoltaic supports will be much higher than steel supports. In the case of general strength requirements, such as metal roof solar bracket, usually the span is relatively small, so the strength requirements are not high, and the aluminum alloy brackets satisfying the strength are basically close to the stainless steel pv bracket in terms of cost, and due to the processing technology The difference in the cross-section of the aluminum alloy bracket makes the aluminum alloy bracket rich in form and convenient to install.
 
In short, for the aluminum alloy photovoltaic bracket or the stainless steel photovoltaic bracket is good for this problem, everyone should fully consider the local installation environment and the wind resistance level of the bracket during the use and selection process.
CHIKO certification
