Solar photovoltaic mounting system (green and environmental protection first choice)

Solar photovoltaic mounts is a special bracket designed for placing, installing and fixing solar panels in solar photovoltaic power generation systems. The general materials are aluminum alloy, carbon steel and stainless steel. The global energy crisis has promoted the rapid development of the new energy industry. Solar energy is the most important basic energy source among all kinds of renewable energy. Therefore, as a solar power generation technology that converts solar radiant energy into electrical energy, the photovoltaic industry is developing rapidly. The application advantages of solar panel support go far beyond simple production and installation. Solar panels can also be moved flexibly according to sunlight and seasons. Just like when it was just installed, the slope of each solar panel can be adjusted to adapt to different light angles by moving the fasteners, and the solar panel can be accurately fixed at the designated position by re-tightening the solar panel.

1. For sloping roof photovoltaic systems, our brackets are generally placed on the roof. Therefore, we must choose the brackets according to the roof type. For sloping roof photovoltaic support equipment, it is very suitable for equipment accessories with different thicknesses and adjustable tile roof heights to meet various application requirements of customers. Moreover, its adjustment is also very convenient, and it can be used without damaging the roof.

2. In the case of a flat roof photovoltaic system with a self-waterproof system, the installation of the support is realized. As the name suggests, the support equipment of the system is a flat roof support installation system, which is more convenient for installation. Because the installation site is relatively flat, it is suitable for large-scale laying and has a variety of stable and reliable basic connection methods. We can also develop unique accessories according to customer requirements to maximize customer satisfaction.

3. The most common photovoltaic support equipment for large ground photovoltaic systems is a large ground photovoltaic system. Large-scale ground photovoltaic power generation systems generally use concrete strip foundations. This kind of bracket installation method can quickly realize the installation, and cooperate with the large-scale ground photovoltaic system to improve the progress of the power station construction team, so it is also the most widely used.

At present, the solar photovoltaic Mounting system widely used in my country is divided into three types: concrete support, steel support and aluminum alloy support.

1. Concrete supports are mainly used for large-scale photovoltaic power stations. Due to its own weight, it can only be placed on site and well-founded areas, but it has high stability and can support large panels.

2. The steel bracket has stable performance, mature manufacturing technology, high carrying capacity, simple installation, excellent anti-corrosion performance and beautiful appearance. Unique connection design, convenient and quick installation, simple and universal installation tools, and the service life of steel and stainless steel parts made of structural anti-corrosion materials is more than 20 years.

3. Aluminum alloy brackets are generally used for solar applications on the roofs of civil buildings. Aluminum alloy has the characteristics of corrosion resistance, light weight, beauty and durability, but its carrying capacity is low, and it cannot be used in solar power station projects.

Comparison of comprehensive performance of photovoltaic support

(1) Aluminum alloy profiles are light in weight, beautiful in appearance and excellent in corrosion resistance. Generally used in rooftop power stations, strong corrosive environments and chemical plant power stations with load-bearing requirements. If aluminum alloy is used as the support, the effect is better.

(2) The steel has high strength and small deflection and deformation when under load. It is generally used for power stations under ordinary conditions or for parts with relatively large forces. In windy areas, where the span is relatively large, the use of steel supports has obvious economic benefits.

(3) Cost: Under normal circumstances, 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 steel structure bracket.

The future trend of solar photovoltaic mounts:

1. The position of photovoltaic brackets in the power station system is getting higher and higher

With the reduction of high-quality sites for photovoltaic power stations, more and more photovoltaic power stations are built in harsh environments, and photovoltaic power stations are built in areas with uneven land. This puts forward higher requirements for the stability and reliability of the photovoltaic support. At the same time, in the context of the gradual decline in photovoltaic subsidies, photovoltaic support, as an important product to reduce costs, improve efficiency, and improve power station investment efficiency, has become a very important part of the power station investment industry.

2. Photovoltaic modules present a high-power trend, which affects the market space of photovoltaic brackets

In recent years, photovoltaic modules have shown a high-power trend. In the future, the power of photovoltaic modules will continue to rise due to the superposition of various factors such as the increase in power of various types of battery modules, heterojunctions, and the continuous popularization of n-pert/TOPCON high-power batteries. The data shows that from 2017 to 2019, the average power of photovoltaic modules in domestic photovoltaic power plants was 313W, 331W and 358W, respectively. It is estimated that the average power of China's photovoltaic modules will reach 420W in 2023.
