Mountain PV Mounting System Manufacturers

Construction and practice of mountain PV mounting system for complex terrain

With the rapid promotion of renewable energy around the world, mountainous areas with complex terrain have gradually been included in the key areas for photovoltaic power generation development. As a key structure connecting photovoltaic components with natural terrain, mountain photovoltaic mountings bear multiple functions such as mounting, fixation, wind and snow resistance, and adaptation to terrain. They are the key link for the long-term stable operation of the entire system.
Taizhou Dongsheng New Energy Technology Co., Ltd. has long focused on the research and development and system integration of photovoltaic mounting products. Its mountain photovoltaic mounting solutions have shown good adaptability and construction efficiency under complex terrain conditions and have been put into practical use in photovoltaic projects in many places.

Development characteristics of mountain photovoltaic projects
Mountain photovoltaic projects are mainly built in non-flat terrains such as mountains, hills, and slopes, and have the following characteristics:
* The terrain is undulating and the geological conditions are changeable: the mounting foundation needs to be personalized according to the specific soil, rock layer, slope and other factors.
* Transportation conditions are relatively inconvenient: component transportation, equipment hoisting, and construction organization are all facing challenges.
* Diverse environmental factors: Mountains are often accompanied by strong winds, strong ultraviolet rays, high cold, heavy rain and other climatic conditions, which put forward high requirements on structural safety and durability.
*High utilization rate of land resources: realize energy development in non-agricultural areas to avoid competing with cultivated land.
These characteristics determine that mountain photovoltaic mounting systems must have high adaptability, structural reliability and installation flexibility.

Structural types of mountain photovoltaic mounting systems
According to different terrains and project requirements, mountain photovoltaic mountings are mainly divided into the following structural forms:
1. Fixed mountain mounting
Fixed mounting is a widely used structural type, and photovoltaic modules are installed on mountings with fixed angles. Depending on the terrain, the height of the mounting column will vary, and the overall balance of the whole column can be achieved by adjusting the foundation height.
* Suitable for slopes with high stability requirements;
* Simple structure and convenient maintenance;
* Low initial investment cost.
2. Adjustable angle mounting
This type of mounting allows the angle of the component to be adjusted in different seasons to improve power generation efficiency. Its structural complexity is relatively high, and it is mostly used in projects with higher requirements for the utilization of light resources.
* Increase the average annual power generation;
* The installation process requires higher precision;
* Usually with ground angle adjustment mechanism or manual adjustment system.
3. Flexible mounting system
The flexible mounting adopts flexible steel cables and modular components, which is suitable for large slopes and continuous undulating terrain. Stability is achieved through tensioning technology, reducing the workload of infrastructure construction.
*Reduce damage to the original terrain;
*Convenient construction and small transportation volume;
*High structural design requirements, requiring professional team evaluation.

Choice of foundation form and construction considerations
The foundation form of mountain mounting is directly related to the safety and life of the overall structure. Common foundations include:
*Screw pile foundation: suitable for soft or shallow rock terrain, fast construction speed and small environmental disturbance;
*Concrete foundation: suitable for areas with stable terrain and high wind and snow loads, with strong compressive resistance;
*Hammer-in steel piles: high equipment requirements, suitable for some rock layer structures.
Taizhou Dongsheng New Energy Technology Co., Ltd. provides personalized foundation type selection solutions according to different mountain conditions, and mountings foundation construction guidance to ensure the efficiency and safety of project implementation.

Installation angle and layout strategy
The component arrangement angle of mountain photovoltaic mountings directly affects the light receiving efficiency and shadow shading:
*Usually, equal spacing is adopted, with the slope facing south;
*The mounting inclination angle is adjusted according to the latitude and slope to avoid back shading;
*The row and column spacing needs to be designed in combination with the size of photovoltaic components, projection length, and local sunshine angle.
A reasonable arrangement strategy can effectively improve the overall power generation efficiency of the system, while reducing the sensitivity of the mounting structure to wind pressure and snow load.

Wind and snow resistant design and environmental adaptability
The wind speed in mountainous areas varies greatly, and the depth of snow in winter is high, which poses challenges to the wind pressure resistance and bearing capacity of the mounting. The mounting system needs to undergo a rigorous structural force analysis:
*The cross section of the beam and the wall thickness of the column need to be calculated based on the maximum wind speed and snow load;
*Structural reinforcement components such as diagonal braces and horizontal tie rods are set;
*For high-altitude areas, thickened mounting pipes can be selected;
*High-strength anti-corrosion bolts are used at the connection between the component and the mounting to prevent loosening.
Dongsheng New Energy introduced finite element analysis in the design of mountain mountings to simulate the structural response under extreme climate in advance and improve the operational stability of the system.

Operation and maintenance convenience and post-management
Due to the complex mountain environment and high post-operation and maintenance costs, the initial design of the mounting needs to consider the structural method that is easy to repair:
* Ensure that there are enough maintenance channels between components;
* All connectors are standardized for easy replacement;
* The mounting material should have good corrosion resistance to extend the service life;
* Cooperate with the intelligent monitoring system to achieve rapid fault location.
Taizhou Dongsheng New Energy Technology Co., Ltd. uses intelligent mounting layout and data collection solutions in multiple mountain projects, combined with drone inspections and other methods to improve the efficiency of post-operation and maintenance.

Future development direction of mountain mounting system
With the development of photovoltaic technology and the intensification of land resource scarcity, mountain photovoltaic projects will continue to expand, and the mounting system will also develop in the following directions:
*Lightweight structure: reduce the difficulty of transportation and installation while ensuring strength;
*Module standardization: improve cross-terrain adaptability and shorten project cycle;
*Intelligent integration: mounting integrated light tracking system, intelligent monitoring module;
*Green construction concept: reduce disturbance to mountain ecology and promote sustainable construction.

From structure to operation and maintenance: full process analysis of mountain PV mounting system

Mountain photovoltaic mounting system is a type of mounting structure developed to adapt to non-flat terrain (such as hills, slopes, terraces, etc.), mainly used for the construction of medium and large ground photovoltaic power stations. Due to the complex mountain environment, conventional mounting systems are difficult to apply directly, so highly adaptable structural design and installation methods are required. Taizhou Dongsheng New Energy Technology Co., Ltd. has formed a systematic and modular mountain photovoltaic mounting solution through years of practical experience, combined with on-site surveys and geological characteristics, which widely serves various irregular terrains.

Height-adjustable and modular structure
Mountainous terrain has problems such as large height differences, different slopes, and loose foundation soil, which puts higher requirements on the adaptability of the mounting system. The mounting system developed by Dongsheng New Energy uses high-strength aluminum alloy or hot-dip galvanized steel as the main material, combined with adjustable height column design, slide-type connection components and multi-point anchoring methods, which can quickly adapt the structural height in different slope areas and achieve a unified inclination angle and arrangement of the overall array.
The advantage of modular design is that it can be freely spliced ​​according to the on-site conditions, reducing the impact of processing errors on construction, and improving transportation and installation efficiency.

Choice of pile foundation and cement foundation
Depending on the different soil structures of the mountains, mountain photovoltaic mountings usually use two types of foundation methods:
*Pile foundation: suitable for mountains with dense soil and strong bearing capacity. C-shaped steel piles or screw piles are driven into the mountain by mechanical equipment, without large-scale excavation, reducing interference with the ecological environment. Taizhou Dongsheng New Energy Technology Co., Ltd. often equips its own pile driving unit in the project to improve the accuracy of pile driving and construction efficiency.
*Concrete foundation: suitable for areas with soft geology or need to improve stability. The use of strip foundation or independent foundation, accurately designed according to the array layout, can effectively improve the wind resistance and anti-slip ability.
In some ecologically sensitive areas, prefabricated foundation blocks can also be used. No cement pouring is required during the construction process, which is convenient for dismantling and restoring the original appearance after the project is completed.

Optimization strategy for installation angle and orientation
The inclination angle of mountain projects is often irregular, and the mounting system needs to have the ability to be flexibly adjusted. It is usually recommended to use a fixed inclination structure, and the inclination is adjusted according to the local latitude, annual average radiation and orientation optimization.
Dongsheng New Energy's engineering and technical team will combine simulation analysis tools (such as PVsyst) to conduct preliminary radiation simulation to confirm the optimal inclination angle and arrangement spacing to avoid shading between components and maximize the power generation per unit area.
For steep slopes running north-south, unequal height mountings can also be used to mounting the components so that the surface of the components maintains a uniform inclination angle and improves the overall performance of the array.

Structural considerations for wind and earthquake resistance
Mountainous areas are often accompanied by natural risks such as high wind pressure, rain, snow and earthquakes. The mounting system must have sufficient structural strength and stable connectors. The mounting system developed by Taizhou Dongsheng New Energy Technology Co., Ltd. uses structural finite element simulation and wind tunnel experiments to ensure the long-term stability of the system.
Most of the connections of its mounting system use a combination of stainless steel bolts and locking nuts. The structure is simple and reliable, which is convenient for later maintenance and reinforcement. For projects in seismic zones, hot-dip galvanized steel and low center of gravity structural layout will be used first to improve the overall seismic resistance.

Construction organization and engineering management requirements
Due to the rugged roads and inconvenient transportation, mountain projects have high requirements for on-site construction management. Dongsheng New Energy usually organizes terrain surveying and mapping in the early stage of the project, formulates transportation channels, hoisting paths and equipment unloading points, and reduces safety hazards during construction.
During the installation process, small machinery or manual combination is often used to build mountings and install components in sections, and a dedicated person is responsible for key links such as structural calibration and bolt torque detection to ensure that the quality of the project is controllable.

Ease of maintenance and long-term operation guarantee
Once the mounting system is put into use, it must have good operation and maintenance convenience. The mountain photovoltaic mounting structure should avoid complex mounting connections as much as possible to facilitate regular inspections and fault replacement.
Dongsheng New Energy considered the maintenance channel reservation of components and mountings at the beginning of the design. The mounting body is clearly marked and the installation record is complete, which is helpful for later system tracking and management. Some projects also combine remote monitoring equipment to provide real-time feedback on the settlement, tilt and stress state of the mounting foundation to form a complete intelligent operation and maintenance system.

mounting materials and processes from the perspective of sustainable development
In order to reduce carbon emissions and environmental loads, the selection of mounting materials tends to be lightweight and highly recyclable. Taizhou Dongsheng New Energy Technology Co., Ltd. promotes the use of recyclable aluminum alloy mountings and detachable connectors to reduce the environmental burden of scrapping in the later stage. In the processing stage, environmentally friendly spraying technology and automatic welding technology are introduced to improve product consistency and service life, which is in line with the overall trend of current green energy development.
