Photovoltaic bracket systems are divided into three categories according to the installation floor:
One is a sloping roof photovoltaic system, the other is a flat roof photovoltaic system, and the third is a large-scale ground photovoltaic system. All three systems have their own advantages and characteristics.
First, our support for sloping roof photovoltaic systems is generally placed on the roof, so we must choose the support according to the type of roof. Regarding the photovoltaic roof support equipment for sloping roofs, it is very suitable for the accessories of different thicknesses of the tile roof and adjustable height equipment to meet the various application needs of customers. Moreover, its adjustment is also very convenient. The installation of the bracket is realized below.
Second, flat roof photovoltaic system This kind of system bracket equipment is the bracket installation system of the flat roof as its name implies, its installation is more convenient. Because the installation floor is relatively flat, it is suitable for large-scale neat laying and has a variety of stable and reliable foundation connection methods. We can also develop unique accessories according to customer requirements so that customers get maximum satisfaction.
Third, the most common type of photovoltaic support equipment for large-scale ground photovoltaic systems is large-scale ground photovoltaic systems. Large-scale ground photovoltaic systems generally use concrete strip foundations. The use of this bracket installation method can quickly achieve installation, and cooperate with large-scale ground photovoltaic systems to improve the progress of power station construction team members, so it is also the most widely used. The above are some types of photovoltaic support systems and their use characteristics. With the development of industry, such equipment will become more and more popular, so we must also be careful when choosing equipment to make our lives more convenient and faster.
How to choose a photovoltaic bracket?
At present, the solar photovoltaic support systems commonly used in China are divided into three types, including concrete supports, steel supports, and aluminum alloy supports.
1. Concrete supports are mainly used in large-scale photovoltaic power stations. Because of their large weight, they can only be placed in areas with good foundations, but they have high stability and can support large-sized solar panels.
Second, the steel bracket has stable performance, mature manufacturing technology, high bearing capacity, easy installation, excellent corrosion resistance, beautiful appearance and unique connection design, easy and fast installation, simple and universal installation tools, steel and stainless steel components with structural anticorrosive materials. Life span is more than 20 years.
3. Aluminum alloy brackets are generally used for solar energy applications on civil building roofs. Aluminum alloys have the characteristics of corrosion resistance, lightweight, beautiful appearance, and durability, but their low bearing capacity cannot be used in solar power station projects.
Fourth, comprehensive performance comparison
(1) Aluminum alloy profiles are light in weight, beautiful in appearance, and excellent in anti-corrosion performance. Generally, it is better to use aluminum alloy as a bracket for roof power stations, strong corrosive environments, and chemical plant power stations that require load-bearing.
(2) The steel is high in strength and small in deflection when subjected to load. It is generally used in power stations under ordinary conditions or for components subject to large forces.
(3) Cost: Generally, the basic wind pressure is 0.6kN / m2 and the span is less than 2m. The cost of aluminum alloy bracket is 1.3-1.5 times that of the steel structure bracket. In a small-span system, (such as a color steel roof), the cost difference between the aluminum alloy bracket and the steel structure bracket 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.
In windy areas, the use of steel supports has a significant economic benefit when the span is relatively large.
