175MW Agri-PV Tracking System | Guangxi, China

February 26, 2026

1. Project Overview

•Project Background：The project is located in Qintang District, Guangxi Zhuang Autonomous Region, and forms a key component of Guangxi’s 2GW multi-energy complementary renewable energy base. It actively responds to China’s national policy promoting integrated “PV+” development models, exploring how large-scale photovoltaic generation can be deeply integrated with modern agriculture in southern hilly regions. By combining utility-scale solar generation with agricultural cultivation, the project aims to achieve the green development objective of “multiple uses on one land parcel, multiplied benefits,” creating a benchmark project that synergizes rural revitalization and energy transition.

•Project Requirements: The site features typical hilly terrain. The client required a high-efficiency PV system capable of adapting to undulating topography, resisting southern China’s strong winds and humid climate, and truly realizing the synergistic benefits of an agri-PV complementary model. Specifically: (1) The tracking mounting system must provide exceptional wind resistance and terrain adaptability. (2) The structural design must reserve sufficient and scientifically planned physical space and light conditions for agricultural cultivation beneath the modules. (3) Advanced technology must be adopted to maximize energy yield and ensure the economic feasibility of the “PV + Agriculture” dual-revenue model.

2. Project Challenges

2.1 Stability Challenges in Hilly Terrain
•Undulating site conditions impose higher requirements than flatland projects on foundation consistency, array alignment control, and overall structural rigidity. The tracking system must maintain stable and synchronized operation under non-ideal terrain conditions.

2.2 Reliability under Southern Wind and Humid Climate
•The site must withstand operational wind speeds of 18 m/s and extreme wind speeds of 22 m/s. In addition, high temperature and humidity present long-term challenges to both electrical systems and metal structure corrosion resistance. The system must demonstrate strong environmental adaptability and lifecycle reliability.

2.3 Spatial and Ecological Coordination in the Agri-PV Model
•To truly achieve “power generation above, cultivation below,” the mounting structure must provide adequate ground clearance and scientifically optimized array layout. It must accommodate agricultural machinery access and crop light requirements without compromising structural safety or energy efficiency.
3. Solution
Antaisolar delivered a customized agri-PV integrated solution centered on a 2P horizontal single-axis tracking system.

3.1 Adapting to Hilly Terrain: High-Rigidity Synchronized Drive Design
• By rigidly linking multiple drive points, the natural frequency of the structure is increased to approximately three times that of conventional systems, significantly enhancing torsional rigidity and overall stiffness. This ensures precise and synchronized tracking motion across all mounting units, even when installed on varying slopes.

3.2 Strengthened Wind Resistance and Certified Reliability
• The 2P horizontal single-axis tracking structure improves wind resistance by nearly two times compared to conventional systems, enabling stable operation at 18 m/s and resistance to extreme wind speeds of 22 m/s.
• The complete tracking system has passed strict certification by TÜV NORD in accordance with International Electrotechnical Commission IEC 62817 standards. This certification verifies long-term operational reliability under harsh conditions and provides strong technical assurance for project financing and insurance.

3.3 Optimized Structural Space for Agricultural Synergy
•The minimum module clearance is set at 2.5 meters above ground, carefully determined to meet the lighting needs of southern crops and cash crops while allowing passage for small and medium-sized agricultural machinery. This achieves the goal of “no compromise on power generation, no disruption to farming.”
• The system supports ±60° large-angle tracking. Through intelligent angle optimization during specific time periods, the array tilt can be adjusted to increase diffuse light beneath the modules, creating more favorable growth conditions for shade-tolerant crops.

4. Project Results

• The 175MW agri-PV power plant has been successfully grid-connected in the Qintang hilly region. The project resolved key technical challenges related to deploying tracking systems in complex terrain while integrating agricultural cultivation, achieving harmonious coordination between PV arrays and modern farming operations in terms of spatial planning, light distribution, and production processes.

• The power plant delivers substantial annual electricity generation, enhancing the regional supply of green energy. Meanwhile, the land beneath the arrays is utilized for specialty crop cultivation, forming a dual revenue stream of “solar power generation income + agricultural product sales income.” This integrated model improves overall land productivity and increases farmers’ income, establishing a virtuous cycle between green power generation and ecological agriculture.For more information, please visit: https://www.antaisolar.com/
