As solar energy projects continue expanding across South America, contractors are increasingly facing difficult construction conditions such as sloping terrain, uneven ground, and mixed soil formations. These challenges often affect piling accuracy, installation efficiency, and overall project costs.
In July 2025, a solar EPC contractor from Colombia found YG Machinery through a Google search while looking for a reliable solar farm pile driver. The company was preparing for a new photovoltaic farm project and needed equipment capable of operating efficiently on complex terrain while meeting a tight construction schedule.
Before contacting YG, the customer had evaluated several suppliers. Some offered lower prices but lacked customization capabilities, while others proposed expensive solutions that exceeded the project budget. After comparing technical specifications, after-sales service, and previous customer feedback, the contractor ultimately selected YG Machinery.
Project Challenges Faced by the Customer
The photovoltaic project was located in a hilly area of central Colombia. During the initial site survey, the customer identified several issues that could potentially delay construction.
Main Challenges
- Large sections of the solar farm were located on sloped terrain.
- Soil conditions varied between compact clay, gravel, and weathered rock.
- More than 8,000 foundation piles needed to be installed before the rainy season.
- The customer wanted one machine capable of handling different ground conditions without frequent equipment changes.
- Local labor costs were increasing, making construction efficiency a key concern.
These challenges are common throughout South America. As more photovoltaic projects move into mountainous and remote areas, contractors increasingly require specialized piling equipment rather than conventional construction machinery.
YG Customized a Professional Solution
After reviewing the project requirements, geological reports, and installation targets, YG engineers recommended a customized hydraulic solar pile driver equipped with hydraulic adjustable support legs and a reinforced crawler chassis.
Instead of offering a standard machine, our engineering team optimized the configuration specifically for hillside solar farm construction.
Key Machine Specifications
| Engine | Yuchai 4108, 88 kW |
| Hydraulic Pump | Triple Pump (40/40/32) |
| Output Torque | 13,000 N·m |
| Max Drilling Depth | 6 m |
| Max Drilling Diameter | 400 mm |
| Drill Rod Speed | 180 r/min |
| Applicable Rock Hardness | 6–20 F |
| Climbing Ability | 45° |
| Machine Weight | 6.5 T |
| Travel Speed | 5 km/h |
These specifications provided sufficient power for drilling through compact soil layers and weathered rock while maintaining excellent operating efficiency.
Features That Solved the Customer’s Problems
To ensure stable operation on difficult terrain, the machine was equipped with:
- Hydraulic adjustable support legs
- Adjustable crawler height range of 80–120 mm
- 45° climbing capability
- 150° drilling boom swing angle (±75°)
- 120° sliding frame pitch angle
- 40° left-right frame swing angle
These features allowed the pile driver for solar farm construction to maintain stability and piling accuracy even when operating on uneven ground.

For overseas contractors, this level of support significantly reduces operational risk.
Outstanding Performance After Arrival in Colombia
Once delivered and commissioned, the machine quickly became one of the most productive pieces of equipment on the site.
According to the project manager, the combination of powerful hydraulics, flexible boom movement, and crawler stability allowed operators to work efficiently across the entire solar farm without major interruptions.
Results Achieved on Site
- ✔ Smooth operation on sloped terrain
- ✔ Stable performance on uneven ground
- ✔ Efficient drilling through clay and weathered rock
- ✔ Reduced machine relocation time
- ✔ Improved daily piling productivity
- ✔ Lower labor requirements
- ✔ Consistent pile verticality within project specifications
The customer particularly appreciated the machine’s performance as a solar pile driver for slope applications. Even in areas with noticeable elevation changes, pile alignment remained accurate and construction efficiency remained high.
Likewise, the equipment proved highly effective as a solar pile driver for uneven terrain, eliminating the need for multiple machines across different sections of the project.
The contractor also noted that the machine functioned as both a high-efficiency solar mounting pile driver and a reliable solar panel pile driver, making it suitable for large-scale photovoltaic installations.
Customer Feedback
Several months after commissioning, the customer shared positive feedback regarding both equipment performance and YG’s service support.
“Before purchasing, we were concerned about operating on steep ground and mixed soil conditions. However, the machine adapted very well to the site. The climbing capability and hydraulic support system provided excellent stability, while the drilling efficiency exceeded our expectations. Whenever we needed assistance, the YG team responded quickly and professionally.”
The customer further reported that maintenance requirements were straightforward and spare parts availability remained excellent throughout the project.
Repeat Order in May 2026
Customer satisfaction is best demonstrated through repeat business.
In May 2026, after successfully completing the first phase of the solar farm project, the Colombian contractor placed another order with YG Machinery for genuine spare parts and maintenance components.
The order included:
- Hydraulic seals
- Filters
- Hydraulic hoses
- Wear-resistant drilling components
- Routine maintenance kits
The customer specifically requested original YG parts to ensure continued performance and maximize equipment service life.
This repeat order further confirmed the reliability of both the machine and YG’s after-sales support system.
