Solar photovoltaic mounting system knowledge
Apr 28, 2020
The photovoltaic mounting system is divided into three categories according to the installation ground:
1.Slope roof photovoltaic system,
2. Flat roof photovoltaic system,
3. Large-scale ground photovoltaic system.
The three systems have their own advantages and characteristics:
1, our brackets for slope roof photovoltaic systems are generally placed on the roof, so we must choose the bracket according to the type of roof. Regarding the slope roof photovoltaic support equipment, it is very suitable for the accessories of tile roofs with different thicknesses and adjustable heights to meet the various application needs of customers, and its adjustment is also very convenient, without damaging the roof waterproof system The installation of the bracket is realized.
2. Flat roof photovoltaic system As the name suggests, this kind of system support equipment is a flat roof support installation system, which is more convenient to install. Because the installation ground is relatively flat, it is suitable for large-scale neat laying and has a variety of stable and reliable basic connection methods. It can also develop unique accessories according to the requirements of customers, so that customers can get maximum satisfaction.
3, the most common type of photovoltaic mounting equipment for large-scale ground photovoltaic systems is large-scale ground photovoltaic systems. Large-scale ground photovoltaic systems generally use concrete strip foundation forms. The use of this bracket installation method can quickly realize the installation, cooperate with the large-scale ground photovoltaic system, and improve the progress of the power station construction team members, so it is also the most widely used.
The above are some types of photovoltaic mounting systems and their use characteristics. With the development of industry, this kind of equipment will become more and more popular, so we must be careful when choosing equipment to make our life more convenient and faster.
How to choose photovoltaic bracket?
At present, the solar photovoltaic mounting system commonly used in China is divided into materials, mainly including three types of concrete support, steel support and aluminum alloy support.
1. Concrete supports are mainly used in large-scale photovoltaic power plants. Because of their self-importance, they can only be placed in the field and have a good foundation. However, they have high stability and can support large-size solar panels.
2, the steel bracket has stable performance, mature manufacturing process, high load capacity, easy installation, excellent anti-corrosion performance, beautiful and unique connection design, easy and fast installation, simple installation tools, general use of steel and stainless steel parts with structural anti-corrosion materials, use The life span is more than 20 years.
3. Aluminum alloy brackets are generally used in solar roof applications for civil buildings. Aluminum alloys have the characteristics of corrosion resistance, light weight, beauty and durability, but their low bearing capacity cannot be applied to solar power station projects.
4, comprehensive performance comparison
(1) Aluminum alloy profiles have light weight, beautiful appearance, and excellent anti-corrosion performance. Generally, they are used for roof power stations, strong corrosion environments, chemical plant power stations, etc. that require load-bearing. Using aluminum alloy as a bracket will have better results.
(2) The steel has high strength and small deflection deformation under load. It is generally used in power stations under ordinary conditions or for components with relatively large stress. In high wind areas, where the span is relatively large, the use of steel supports has obvious economic benefits.
(3) Cost: In general, the basic wind pressure is 0.6kN / m2 and the span is less than 2m. The cost of the aluminum alloy bracket is 1.3-1.5 times that of the steel structure bracket. In a small-span system, the cost difference between the aluminum alloy bracket and the steel structure bracket (such as color steel plate roof) is relatively small, and the aluminum alloy is much lighter than the steel bracket in terms of weight, so it is very suitable for roof power stations.
