Amid the global transition to clean energy, solar energy, as one of the most promising renewable energy sources, is experiencing a continuous expansion in its application. Within the entire solar power generation system, ground-mounted solar mounting systems play a crucial role. They not only support the core structure of the solar panel system but also directly impact the efficiency, stability, and lifespan of solar power generation. This article comprehensively analyzes this critical equipment, including its core components, advantages and features, installation process, key considerations for purchasing, and future development trends. This article aims to help industry practitioners and investors gain a deeper understanding of the value of solar mounting systems.
A ground-mounting solar mounting system is a support structure specifically designed for ground-mounted solar panel systems. It allows precise angle adjustment based on the geographical environment, climate conditions, and installation requirements of the solar panels, ensuring that the solar panels receive maximum solar radiation, thereby improving the overall system's efficiency. Compared to rooftop solar mounting systems, ground-mounting solar mounting systems offer significant advantages in terms of installation space, layout flexibility, and ongoing maintenance. Therefore, they are widely used in large-scale photovoltaic power plants, distributed industrial and commercial photovoltaic projects, and family farms.
For a complete solar panel system, the ground-mounting solar mounting system is like the "solid skeleton," supporting the weight of core equipment such as solar panels, inverters, and cables. If the mounting system is unstable or poorly designed, not only can the solar panels' installation angle deviate, affecting power generation efficiency, but it can also cause structural damage in extreme weather conditions (such as strong winds, heavy rain, and snowstorms), leading to safety accidents and significant economic losses. Therefore, selecting a high-quality, high-performance ground-mounting solar mounting system is crucial for ensuring the long-term stable operation of a solar panel system.
A complete ground-based solar mounting system consists of multiple core components, each of which plays an indispensable role. Ground screws, steel channels, as well as the main support beams, diagonal braces, and connectors, form a stable and reliable support structure.
1. Ground Screws: The "Foundation" of the Mounting System
Ground screws are the key components that connect the ground-based solar mounting system to the ground. Their primary function is to secure the mounting system to the ground, bearing the weight of the entire solar panel system as well as external loads such as wind and snow, ensuring that the mounting system does not tilt or shift. Compared to traditional concrete foundations, ground screws offer advantages such as ease of installation, the elimination of extensive excavation, and minimal environmental impact. During installation, the ground screws are simply driven into the ground using specialized equipment, significantly shortening the construction period and reducing costs. Currently, ground screws on the market are primarily made of high-strength steel and undergo anti-corrosion treatments such as hot-dip galvanizing, effectively resisting soil corrosion and extending their service life. Ground screw specifications, lengths, and thread designs vary depending on geological conditions (such as soil type and bearing capacity). For example, in soft soil, longer ground screws with deeper threads are required to ensure sufficient anchoring force; in hard rock formations, specialized ground screws are required in conjunction with drilling equipment.
2. Steel Channel: The "Load-Bearing Backbone" of the Mounting System
The steel channel is the primary structural component of a ground-based solar mounting system, supporting solar panels and typically serving as the horizontal or vertical beams of the mount. Featuring high strength and rigidity, the steel channel can withstand the weight of the solar panels and external loads, while also accommodating various mounting angles. In terms of material selection, steel channels are typically made of high-quality carbon structural steel such as Q235 or stainless steel. Some products also undergo cold-bend forming to enhance structural stability and compressive strength. Furthermore, to withstand harsh outdoor environments, steel channels are typically treated with anti-corrosion treatments such as hot-dip galvanizing or spray coating to effectively prevent rust and corrosion, thereby extending the lifespan of the mounting system. In actual applications, the specifications and dimensions of the steel channels must be carefully selected based on factors such as the scale of the solar panel system, the size of the solar panels, and the mounting angle to ensure the mounting system's load-bearing capacity meets design requirements.
3. Other Core Components: The "Details That Ensure Stable System Operation"
In addition to ground screws and steel channels, ground-mounted solar mounting systems also include components such as the main support beam, diagonal braces, connectors, and angle adjustment devices. The main beam is the primary structure connecting the steel channels, providing overall load-bearing and stability. Diagonal braces enhance the system's wind resistance and stability, preventing deformation in strong winds. Connectors connect individual components, ensuring the integrity of the entire system. The angle adjustment device allows for flexible adjustment of the solar panel's mounting angle based on seasonal variations in the sun's altitude, further improving power generation efficiency.
Though seemingly small, these components are crucial details that ensure the stable operation of ground-based solar mounting systems. When selecting these components, attention should be paid to their material, machining precision, and corrosion resistance, ensuring that each component works seamlessly with the others to create a reliable solar mounting system.
Compared to other types of solar mounting systems, such as rooftop and wall-mounted systems, ground-mounted solar mounting systems offer numerous significant advantages, making them the preferred support solution for solar panel systems in scenarios such as large-scale photovoltaic power plants and commercial and industrial photovoltaic projects.
1. Flexible Installation Space and High Layout Freedom
Ground-mounted solar mounting systems are not restricted by factors such as building roof area and structural form, allowing for flexible layouts tailored to the specific site conditions. Whether on open wasteland, farmland, hillsides, or rooftops, as long as the ground conditions meet the requirements, ground-mounted solar mounting systems can be installed. Furthermore, ground-mounted solar mounting systems can be configured in a variety of layouts, such as row and matrix, depending on the scale and power generation requirements of the solar panel system, maximizing site space and improving land utilization.
2. Higher Power Generation Efficiency and Easier Angle Adjustment
The power generation efficiency of solar panels is closely related to the amount of solar radiation received, and the solar altitude angle varies with the seasons and time of day. Ground-mounted solar mounting systems are equipped with flexible angle adjustment mechanisms, allowing them to precisely adjust the mounting angle of the solar panels based on latitude, seasonal variations, and the sun's trajectory. This ensures the panels always receive the optimal solar radiation, significantly improving power generation efficiency. In contrast, rooftop solar mounting systems, due to the limitations of the roof structure and load-bearing capacity, often lack the flexibility to adjust the angle, which can also affect power generation efficiency.
3. Easy Maintenance and Low Operating Costs
Ground-mounted solar mounting systems are installed on the ground, keeping the solar panels relatively low. This allows maintenance personnel to easily access the installation for inspection and cleaning. For example, if dust or debris accumulates on the solar panels, affecting power generation efficiency, maintenance personnel can easily clean them. If a system malfunction requires component replacement, they can also quickly disassemble and install them. Furthermore, the relatively simple structure of ground-mounted solar mounting systems reduces failure rates, effectively reducing ongoing operating and maintenance costs and improving the return on investment of the solar panel system. 4. Adaptable to Harsh Environments and Strong Stability
The ground-mounted solar mounting system utilizes high-strength materials (such as steel channels and ground screws) and a rational structural design, effectively withstanding harsh environmental factors such as strong winds, heavy rain, heavy snow, and earthquakes. For example, in areas with strong winds, the mounting system enhances wind resistance by adding diagonal braces and optimizing connector design. In areas with heavy snow, the mounting system's load-bearing structure is specially designed to withstand the pressure of heavy snow. Furthermore, the use of ground screws ensures the mounting system's stability in diverse geological conditions, preventing damage to the system due to foundation settlement and other issues.
