When we talk about the solar industry, our eyes are often focused on those high-end components, inverters, and even the most cutting-edge technological breakthroughs. However, there is a seemingly insignificant component that silently plays a vital role in the solar system-fasteners. Don't underestimate these small parts, they are the "Joints" Of solar panel mount and the key to the stability and safety of the entire system. Today, let us explore the importance of fasteners in solar panel mount and their future development direction.
In order for solar panel mount to stand firmly and form a solid frame, fasteners are indispensable. Taking the common ground solar power station as an example, rows of neatly arranged solar panel mount are like a steel forest. From columns, beams to diagonal braces, the various components of the bracket are tightly connected by fasteners. If the solar panel mount is compared to the human body, fasteners are like joints, which allow each "Skeletal" Component to be closely connected to build a stable structure. Once these "Joints" Are missing or the "Joints" Are not strong enough, the entire solar panel mount will fall apart and will not work properly at all.
Let's take a look at those distributed solar projects, such as solar systems installed on roofs. The shapes and slopes of roofs vary, and solar panel mount need to be flexibly built according to actual conditions. At this time, the role of fasteners is even more critical. They can enable the brackets to adapt to various complex conditions on the roof, achieve precise installation, and ensure that the solar system is firmly "Rooted" On the roof.
In the face of various tests of nature, fasteners are a solid shield for solar panel mount. Every year, many areas are attacked by typhoons and hurricanes, and the power of strong winds should not be underestimated. If solar panel mount want to stand firm in strong winds, fasteners must be strong enough. Through high-strength bolts, nuts, etc., the various parts of the bracket are firmly locked to increase the overall wind resistance and reduce the risk of being blown over or blown off by the wind. Relevant studies have shown that in some areas with frequent strong winds, solar panel mount with reasonable selection of fasteners can withstand the attack of typhoons above level 12.
In winter, heavy snow accumulation will also bring great pressure to solar panel mount. If the fasteners are of poor quality and the connection parts are loose, the bracket may not be able to withstand the weight of the snow and collapse. High-quality fasteners can ensure the stability of the bracket structure, effectively disperse the pressure of the snow, and ensure that the solar system safely passes the snow season.
Earthquakes are also a big challenge. When the earthquake wave comes, the ground shakes violently, and the solar panel mount will be subjected to a strong impact. At this time, reliable fasteners can make the various parts of the bracket deform synergistically, absorb and disperse the seismic energy, reduce the probability of damage caused by the earthquake, and protect the safety of the solar system.
Among the fasteners of solar panel mount, the bolt and nut family is definitely the main force. High-strength hexagonal bolts are very common in various solar projects due to their excellent strength and easy operation. In large-scale ground solar power stations, it can firmly fix the main components of the bracket, withstand huge tension and pressure, and ensure that the bracket will not fall apart in harsh environments.
Hot-dip galvanized bolts are also a good hand. It is hot-dip galvanized to form a solid zinc layer on the surface, just like putting a layer of armor on the bolt, greatly improving the corrosion resistance. In humid and corrosive environments such as the seaside, hot-dip galvanized bolts can effectively resist the erosion of seawater and sea breeze and extend the service life of solar panel mount. Data shows that the service life of solar panel mount using hot-dip galvanized bolts in coastal areas can be extended by 5-10 years compared with ordinary bolts.
Let's take a look at Spring nuts. They are usually made of nylon and other materials. The biggest feature is good insulation performance. In some solar scenarios that require insulation, such as distributed solar projects, if solar components need to be isolated from the metal structure of the building to prevent current conduction from causing safety problems, Spring nut come in handy. They can not only achieve the fastening connection of components, but also effectively prevent the passage of current to ensure the safe operation of the system. In addition, the installation of spring nuts is also very convenient. They can be tightened by hand, which is simple to operate and can significantly improve the installation efficiency.
In addition to the above common fasteners, there are many special fasteners that also play an important role in solar panel mount. Drilling screws are a good example. It can be drilled directly into metal, wood and other materials without drilling holes in advance, which is convenient and fast. In some small solar projects or scenarios with high requirements for installation speed, self-drilling screws can greatly shorten the installation time and improve construction efficiency. For example, in rooftop distributed solar projects, workers can quickly fix the solar panel mount to the roof structure with self-drilling screws, saving the tedious steps of drilling holes.
Combination screws combine screws and washers together, and can achieve the dual functions of fastening and anti-loosening in one installation. In some parts of solar panel mount, it is necessary to prevent screws from loosening, and combination screws can well meet this demand and reduce subsequent maintenance costs.
With the urgent global demand for clean energy, the solar industry has ushered in explosive growth. The international energy agency (iea) predicts that the global solar power generation installed capacity will continue to rise sharply in the next few years. This growth trend has directly driven the booming solar panel mount fastener market. From the perspective of market size, according to statistics from professional institutions, the solar fastener market has grown at a double-digit rate every year in the past few years. It is expected that in the next five years, the global solar fastener market will exceed the us$10 billion mark.
In terms of application scope, fasteners are not only widely used in large-scale ground solar power stations, but also in distributed solar projects. The demand for fasteners is growing rapidly. In some european countries, distributed solar projects are very popular, and a large number of rooftop and wall solar systems are installed, which has led to a sharp increase in the use of fasteners. In addition, with the expansion of solar technology in agriculture, fisheries and other fields, such as the rise of agricultural and solar complementary and fishery solar complementary projects, the application scenarios of fasteners are becoming more and more extensive, and the market demand continues to expand.
In terms of materials, the application of new materials is becoming a major trend in the development of fasteners. The research and development and application of corrosion-resistant materials make fasteners durable even in harsh environments. For example, in highly corrosive environments such as the seaside and chemical plants, traditional steel fasteners are prone to rust and corrosion, resulting in loose connections and affecting the stability of solar panel mount. Now, some fasteners made of new corrosion-resistant alloy materials can effectively resist the erosion of seawater and chemicals, greatly extending the service life of solar panel mount.
High-strength materials are also emerging. High-strength alloy steel, titanium alloy and other materials are stronger than ordinary steel and can withstand greater tension, pressure and shear force. In large-scale solar power stations, the bracket needs to withstand huge weight and various external forces. Fasteners made of high-strength materials can ensure that the bracket is stable and reliable under various complex conditions, reducing safety hazards caused by fastener failure.
From a design perspective, optimized design is allowing fasteners to play a greater role in solar panel mount. Taking the patent "A fastening component, purlin,solar panel mount and solar system" Obtained by dong fang risheng in 2024 as an example, the clamping part design of the fastening component is very clever, and two different clamping areas are set. The first clamping area is specifically used to tightly press the edge of the solar module to ensure the stability of the module installation; the second clamping area is equipped with an adjustment threaded hole, which cooperates with the support rod to effectively avoid the tilt of the clamping part and further enhance the stability of the entire solar module structure.
This innovative design not only improves the fastening effect, but also improves the installation efficiency. During the actual installation process, workers can operate more conveniently and quickly, reducing installation time and labor costs. Moreover, a stable fastening structure helps to improve the power generation efficiency of the solar system, because a stable bracket can ensure that the solar components are always at the best lighting angle, reducing the power generation loss caused by component shaking and displacement.
With the rapid development of science and technology, intelligence has also begun to emerge in the field of fasteners. In the future, fasteners with intelligent sensing functions may become the new favorite of solar panel mount. Imagine that these fasteners have built-in sensors that can monitor their own stress conditions, temperature, humidity and other parameters in real time. Once a fastener is found to be loose, abnormally stressed or corroded, the sensor will immediately transmit the information to the monitoring system, and the staff can perform maintenance and replacement in time to avoid losing the big picture due to small things, and ensure the safe and stable operation of the solar system.
Intelligent fasteners can also be combined with big data and cloud computing technologies to predict the service life and maintenance cycle of fasteners through the analysis of large amounts of data, and achieve preventive maintenance. This can not only reduce maintenance costs, but also improve the reliability and availability of solar systems, and provide strong support for the efficient development of the solar industry.
The role of fasteners in solar panel mount cannot be underestimated. From building a stable frame to resisting natural invasion, from a variety of types to wide market applications, to a potential development trend, they all play a key role. With the continued vigorous development of the solar industry, fasteners will also usher in more innovation opportunities. Let us look forward to these small parts creating more possibilities in the future solar field and contributing more to the development of clean energy.
