Cambodia 67MW Ground PV Solutions
about project
As Southeast Asia accelerates its transition toward cleaner energy, Cambodia has embraced solar power as a key driver of its renewable energy agenda. This 67MW ground-mounted solar power plant, located in a flat terrain area in Cambodia, features 201,600 PV modules rated at 330W each, with a total installed capacity of 66.528 MW.
Modules are sized at 1987 × 995 × 40 mm, mounted in portrait orientation with a 10° tilt angle, and the structure is engineered to withstand wind speeds of up to 25 m/s. SoEasy provided the complete aluminum ground mounting system, including technical design, structural supply, and on-site installation guidance.
Mounting System Design and Technical Features
The mounting structure is constructed using anodized aluminum alloy, chosen for its excellent strength-to-weight ratio, corrosion resistance, and durability in humid climates. All components, including upright posts, horizontal beams, rails, bracing bars, and connection fittings, are precision-manufactured to ensure dimensional consistency and ease of installation.
Mechanical fastening is achieved using SUS304 stainless steel bolts and nuts, ensuring high structural integrity and long-term reliability under varying dynamic loads.
Module Layout and Array Configuration
The PV modules are arranged in a 2-in-portrait (2P) configuration, with two modules stacked vertically per mounting unit. The layout was carefully designed to optimize:
- Ground coverage ratio (GCR) and land utilization;
- Ventilation for thermal dissipation, reducing hotspot risks;
- Maintenance access and cable management;
- Aesthetics and mechanical uniformity.
All dimensions—including inter-row spacing, edge clearances, and elevation—were calculated to prevent inter-array shading and allow for structural adjustment during installation.
Foundation System and Terrain Adaptability
The project adopts a concrete foundation scheme with each vertical post anchored via base plates and pre-embedded bolts. This setup provides robust pull-out resistance and anti-uplift performance under wind loading conditions.
The mounting system offers field-adjustable installation tolerances, allowing it to adapt to minor topographic variations without additional civil work. This design significantly reduces on-site construction complexity and speeds up installation.
Installation was carried out in strict accordance with the official manual and engineering drawings. The process included the following stages:
Foundation layout and template setup for precise alignment of embedded bolts;
Vertical post erection, with strict control of plumb tolerance;
Beam and rail assembly, using pre-punched holes and custom clamps for accurate positioning;
Module mounting with mid- and end-clamps, torqued to specification to ensure uniform pressure;
Bracing installation to enhance rigidity and wind resistance.
Wind Load Resistance and Durability
The system was engineered to withstand design wind speeds of 25 m/s, a critical requirement given Cambodia’s tropical monsoon climate. Structural analysis and finite element modeling (FEM) were conducted to verify:
- Yield and safety limits under peak wind pressure;
- Bracing stability and torsional resistance;
- Vibration behavior and resonance risks.
All aluminum profiles were anodized for enhanced corrosion protection, and all fasteners were treated or made from stainless steel to prevent galvanic corrosion. The expected system service life exceeds 25 years under outdoor exposure.
The 67MW ground-mounted solar project in Cambodia showcases SoEasy’s capabilities in delivering reliable, cost-effective, and technically robust PV mounting solutions in complex environmental conditions. From modular structural design and component precision to on-site supervision and wind load engineering, this project underscores our commitment to quality and performance in utility-scale solar development.
