Agricultural Solar Mount

Agricultural photovoltaic (PV) support systems demonstrate multi-dimensional value advantages in planting and breeding scenarios, specifically in the following five aspects:

▶ Photovoltaic Power Generation, Increasing Income and Efficiency

• Electricity Revenue: The system continuously generates electricity using photovoltaic panels, which can be sold to the grid or used for self-consumption. Taking the 400 MW photovoltaic-livestock complementary project in Shangyi County, Hebei Province as an example, it uses 650 watts/panel monocrystalline silicon bifacial photovoltaic modules, increasing annual power generation by 15% compared to traditional modules. The CITIC Pacific Energy Tonglu photovoltaic-livestock complementary project is expected to generate an average of 110 million kWh annually, saving 13,500 tons of standard coal and reducing carbon dioxide emissions by 35,400 tons.

• Electricity Cost Savings: Photovoltaic panels can provide self-consumed electricity for farms or planting bases, reducing operating costs. Some farms have reported that the "photovoltaic-livestock complementary" model can save them approximately 30% on electricity costs.

▶ Improving the Breeding Environment (Breeding Scenarios)

• Summer Shading and Cooling: Photovoltaic panels provide a natural "shade" for farmed animals in summer, effectively reducing the temperature of the breeding environment. In integrated livestock and solar power projects, solar panels can lower sheepfold temperatures by 3-5 degrees Celsius in summer, providing suitable conditions for livestock growth.

• Winter insulation and wind protection: Solar panels also provide insulation in winter, reducing heat loss and improving the winter living environment for livestock.

• Reducing heat stress: Solar panels provide shade for livestock, reducing heat stress and promoting a healthier breeding environment.

▶ Customizable and Rapid Assembly

• The product adopts a modular design, with extensive pre-assembly completed before shipment. On-site installation requires no cutting or drilling, only bolt connections, significantly shortening the construction cycle. It can also flexibly adapt to customers' customized needs in terms of different spans, parking space numbers, and structural forms, meeting the "one plan, one design" project requirements.

▶ Optimizing the planting environment (planting scenarios)

• Regulating sunlight: By controlling the spacing between solar panels (widening to over 4 meters, achieving a light transmittance of 30%-70%), suitable lighting conditions can be provided for crops with different light requirements. In tea-solar hybrid projects, solar panels reduce direct sunlight in summer, and combined with the tea trees' preference for diffused light, improve tea quality while generating electricity.

• Protecting crops: Solar panels can protect crops from hail, frost, drought, and overheating, stabilizing yields.

• Significant water saving effect: The shading effect of solar panels reduces soil moisture evaporation, saving approximately 20% of irrigation water. 

▶ Efficient Land Use

• Dual-use of land: Achieving a three-dimensional land use model of "power generation on the roof, planting/breeding under the roof," significantly improving the comprehensive output efficiency per unit area of ​​land. For example, the "livestock-solar complementary" breeding community in Heli Town achieves efficient three-dimensional space utilization.

• Improved land composite utilization rate: In the tea-solar complementary project, a large-spacing, high-support, single-row arrangement of components is adopted to maximize the use of tea garden space and ensure ecological sustainable development. The flexible support system can also increase land utilization by more than 30%.

▶ Promotion of Circular Agriculture

• In the livestock-solar complementary scenario, the manure from livestock raised under the photovoltaic panels, after fermentation, can be used as organic fertilizer for surrounding farmland, reducing the use of chemical fertilizers and forming a circular agricultural industry chain of "photovoltaic power generation—specialized breeding—ecological planting."

Applicable Scenarios

▶ Photovoltaic + Planting Scenarios

Agricultural photovoltaic (PV) support systems have been successfully applied in various planting scenarios:

 

• Tea-PV Complementary System: In Menghai County, Xishuangbanna, Yunnan Province, a "power generation on the panels, tea planting underneath" model is adopted. Combining the characteristics of tea trees—their preference for shade, moisture, and diffused light—an innovative approach using large spacing, high supports, and single-row module arrangement improves tea quality while generating electricity, effectively achieving "dual use of land."

 

• Medicinal Herb-PV Complementary System: In Ningming County, Guangxi Province, a three-dimensional intercropping model of "PV project + enterprise + traditional Chinese medicine" is adopted. Five-finger peach is intercropped under more than 1,300 mu of photovoltaic panels, with a yield of up to 1,000 kg per mu and a profit of over 10,000 yuan, achieving power generation on the panels and medicinal herb planting underneath. Xifeng County, Guizhou Province, is also exploring a new "power generation on the panels, medicinal herb planting underneath" model, planning to plant Asparagus and other traditional Chinese medicines under more than 2,000 mu of photovoltaic panels.

 

• Orange/Fruit Photovoltaic Complementary Project: In Xinping County, Yuxi, Yunnan Province, a photovoltaic power generation project integrating agriculture and forestry with orchards has been combined to form an "orange photovoltaic complementary" demonstration project. Jusheng Technology's flexible photovoltaic supports are also erected above the orchards, providing ample sunlight and space for crop growth.

 

• Conventional Planting: On barren mountains or slopes, a high-support, wide-spacing model is adopted. The photovoltaic supports are raised to 2.5 meters above the ground, with a fixed tilt angle of 27 degrees, achieving "segmented" utilization of sunlight. High-efficiency medicinal herbs and high-efficiency agricultural economic products are planted under the panels.

 

▶ Photovoltaic + Livestock Farming Scenarios (Livestock Photovoltaic Complementary Project)

 

• Livestock Farming (Cattle and Sheep): In Shangyi County, Hebei Province, a 400 MW livestock photovoltaic complementary project uses monocrystalline silicon bifacial photovoltaic modules. The modules are installed on concrete tubular supports, providing strong load-bearing capacity and resistance to friction and collisions from livestock. In the Xinhua Town livestock photovoltaic integrated project, the photovoltaic panels lower the temperature of the sheepfold by 3-5 degrees Celsius in summer, providing suitable conditions for sheep growth.

 

• Poultry Farming: In the "livestock-solar complementary" breeding area in Heli Town, Gaotai County, free-range chickens and geese are raised under photovoltaic panels. The photovoltaic panels provide a natural "shade" and a suitable microclimate for the poultry. At the Huamachi Photovoltaic Power Station of Fugu Energy Dingbian New Energy Company, the photovoltaic panels not only generate electricity but also provide natural shelter for livestock, offering shade in summer and wind protection in winter, resulting in healthier growth for chickens and sheep.

 

• Fish-Solar Complementary: In the Pearl River Delta and Central China lake areas, flexible photovoltaic support systems utilize a large-span design to reduce the number of pile foundations, greatly minimizing interference with fishpond aquaculture activities. Scientifically calculated row spacing ensures sufficient underwater sunlight, achieving a perfect integration of photovoltaic power generation and high-end aquaculture.

 

 

Important Notes:

▶ Design Phase Considerations

• Crop/Livestock Light Requirements Survey: A thorough survey of the light requirements of the crops being grown is necessary. Some agricultural-photovoltaic complementary projects have experienced reduced crop yields or a "light-over-farm" phenomenon due to limitations in technology such as fixed supports. The spacing and tilt angle of the components should be adjusted according to the crop's light saturation to avoid excessive shading.

 

• Agricultural Mechanization Compatibility: If large agricultural machinery is planned for the planting area, the lowest point of the support frame should be designed to be at least 4-5 meters above the ground, and anti-vibration supports should be installed to prevent collisions with the machinery.

 

• Animal Husbandry Activity Space Provision: In livestock husbandry scenarios, sufficient space for livestock activity and personnel inspection should be provided. The spacing between support columns should meet the animal passage requirements.

 

• Prior Geological Survey: Appropriate foundation types should be selected based on soil type—soft soil foundations require careful evaluation, while helical piles can be used to improve construction efficiency in permafrost/rock layers.

 

• Climate conditions must be fully considered: In typhoon-prone areas, wind-resistant design needs to be enhanced (cable net structures should undergo wind tunnel testing); in high-altitude and cold regions, snow load calculation is required.

 

▶ Installation Stage Precautions

• Foundation Construction Quality: The support foundation should be firm, with adequate pull-out resistance, and installation deviation controlled within ±5mm.

 

• Installation Accuracy Control: The angle between the horizontal and vertical planes should conform to the design tilt angle, with an installation error not exceeding ±2°.

 

• Fastener Specifications: Matching standard parts must be used at the connection points of support components, and the tightening torque should meet the specifications. Reducing the number of bolts, flat washers, and spring washers is strictly prohibited.

 

• Corrosion Protection: Steel section cuts should be treated with anti-corrosion measures, welds should be ground smooth, and interfaces should be free of burrs.

 

 

Summary

Agricultural photovoltaic (PV) support systems are core infrastructure for agro-photovoltaic and pastoral-photovoltaic complementary models. They cleverly integrate photovoltaic power generation with agricultural production, achieving an innovative land use model of "power generation on the panels, planting/breeding underneath."

 

From a technical perspective, the system offers flexible configuration options based on specific application scenarios: In planting scenarios, designs such as high supports (≥2.5 meters), large spacing (6-20 meters), and controllable light transmittance (30%-70%) create suitable lighting and growth space for crops underneath; in livestock scenarios, the PV panels combine power generation with shading, cooling, wind protection, and insulation, effectively reducing the temperature of the livestock environment by 3-5°C in summer and saving approximately 30% on electricity costs for livestock farms.

 

From an economic perspective, the system achieves the dual value of "increased income from power generation + agricultural output." Taking a 400MW agricultural photovoltaic power station as an example, the annual power generation can reach hundreds of millions of kilowatt-hours, while also producing tens of millions of kilowatt-hours of green electricity. Furthermore, it can be used for intercropping with medicinal herbs, tea, fruits, and other cash crops, increasing the income of surrounding farmers and forming a sustainable circular economy chain.

 

From a policy perspective, this system actively responds to the national "dual-carbon" strategy and rural revitalization policies, adapting to the policy environment of "comprehensive land utilization" and "agricultural carbon emission reduction." As the photovoltaic industry as a whole develops towards diversified scenarios and eco-friendly directions, the application space of agricultural photovoltaic support systems will continue to expand.
