Located in a hilly area of Feicheng, the project was developed on complex mountain terrain where every stage-from site selection and system design to construction and commissioning-required careful coordination. Unlike flat-ground PV installations, mountain solar projects must balance power generation performance with terrain adaptability, geotechnical safety, drainage control, construction access, and long-term maintenance requirements.
During the early planning stage, the project team faced several challenges. The site featured uneven slopes, varying orientations, fragmented usable areas, and potential shading differences between sections of the mountain. A standard layout approach would have increased row-to-row shading, cable routing distances, and installation difficulty. To address this, the project was divided into multiple terrain-based zones. Array layouts, tilt angles, string configurations, and equipment locations were adjusted according to slope direction, elevation changes, and solar exposure conditions.
Geotechnical conditions were another key consideration. Mountain sites often contain weathered rock, uneven soil layers, local hard rock zones, and areas vulnerable to surface runoff. Before construction, detailed site surveys and targeted geotechnical investigations were carried out to help determine the most suitable foundation and mounting solutions for different areas of the site. This reduced the risk of installation delays caused by unexpected ground conditions and supported a more stable, adaptable array structure.
Drainage and erosion prevention were also treated as essential parts of the project design. Heavy rain can create runoff channels on mountain slopes, potentially affecting foundations, cable trenches, access roads, and surrounding land. The engineering team incorporated slope drainage, intercepting ditches, runoff channels, and localized reinforcement measures into the civil works plan. These measures were designed to guide rainwater safely through the site, minimize soil erosion, and help protect the infrastructure throughout the project lifecycle.
Construction logistics presented an additional challenge. Transporting materials and equipment across mountain roads requires careful planning, particularly for large electrical equipment, mounting materials, cable drums, and construction machinery. Access routes, turning areas, and temporary working platforms were coordinated in advance to improve delivery efficiency and reduce disruptions during installation.
SINELINK was proud to support the project by supplying PV cables and related electrical accessories for the solar power system. Reliable cable performance is especially important in mountain applications, where long routing distances, changing elevations, outdoor UV exposure, temperature fluctuations, and complex installation conditions place higher demands on electrical components.
The supplied cable and accessory solutions were selected to support safe, organized, and durable installation across the site. With appropriate routing and connection planning, the products helped ensure stable power transmission between PV arrays, combiner systems, inverters, and other key electrical equipment. Our support focused not only on product supply, but also on helping the project maintain practical installation efficiency and dependable long-term operation.
Now entering the operation and maintenance stage, the Feicheng Humen 10 MW Solar Project is positioned to provide clean electricity while contributing to the local transition toward low-carbon energy. Routine inspection of PV modules, cable systems, drainage facilities, mounting structures, and access roads will remain essential to maintaining system availability and protecting long-term project performance.
