In April 2026, a customer in Malaysia contacted YG Machinery looking for a solar post driver for a photovoltaic project.
The customer planned to install H-shaped solar mounting piles to an approximate depth of 500 mm and required a target installation capacity of around 300–500 piles per day.
To meet this high-volume piling requirement, YG recommended the YG-699-3 multifunctional drilling and piling machine, equipped with two power heads: a pile-driving power head and a high-torque drilling power head.
The configuration gives the customer a dedicated piling solution for repetitive solar post installation while retaining the flexibility to use different working methods when project conditions require them.
Multi-functional drilling rig for screw pile driving, foundation drilling, and down-the-hole (DTH) drilling. Designed for screw piles, H-type and C-type steel sheet piles, photovoltaic (solar) pile driving, DTH hammer operations, and civil foundation piles. Made from durable manganese steel, it provides versatile and reliable performance for construction and foundation projects.
The customer’s requirements were focused on fast and repeatable solar pile installation.
The main requirements included:
H-shaped solar mounting piles
Approximately 500 mm installation depth
A target of 300–500 piles per day
A crawler-mounted machine suitable for outdoor solar construction
Sufficient piling capability for continuous installation
Flexibility to use different piling or drilling methods when required
For this type of project, equipment selection is not only about maximum piling force. The machine also needs to support repetitive positioning, movement between piling points, and continuous operation across the construction site.
The YG-699-3 was selected because of its two-power-head configuration.
1.Pile-Driving Power Head
The pile-driving power head is used for direct impact installation of suitable solar mounting piles.
For the Malaysian project, the main application was the installation of H-shaped piles to an approximate depth of 500 mm.
Direct pile driving provides a straightforward installation method when the pile and ground conditions are suitable for impact driving.
2.High-Torque Drilling Power Head
The second power head provides high-torque drilling capability.
Depending on the project requirements, it can support operations such as:
Pilot-hole drilling
Pre-drilling before pile installation
Helical pile installation
DTH drilling when the appropriate configuration is used
This means the YG-699-3 is not limited to a single installation method. Contractors can select the appropriate working method according to the pile design and actual site conditions.
The Malaysian customer required a target installation capacity of approximately 300–500 piles per day.
This made productivity one of the key considerations when selecting the equipment.
For a high-volume solar installation project, the piling machine needs to repeatedly complete the basic cycle:
Position → Drive → Reach Required Depth → Move to the Next Pile
The YG-699-3 is designed as a crawler-mounted piling machine, allowing it to move between working positions on the construction site while the piling system handles repetitive installation work.
The customer’s 300–500 piles/day requirement therefore became an important factor in the machine selection and configuration.
Note: The 300–500 piles/day figure represents the customer’s target requirement for the project, not a guaranteed machine output under all working conditions.
For solar projects with a large number of repetitive foundation piles, contractors often need to balance installation speed, pile type, required depth, and site conditions.
The YG-699-3 combines two different working capabilities on one machine:
Pile-driving power head ↓ Direct installation of suitable H-shaped solar piles
High-torque drilling power head ↓ Pre-drilling, helical pile installation, or DTH drilling when required
This makes the machine suitable for projects where the contractor wants both high-volume pile installation and additional drilling flexibility.
The Malaysian case demonstrates a different application of the YG-699-3 from projects where drilling capability is the primary concern.
Here, the customer’s priority was high-volume H-pile installation with an approximate 500 mm embedment requirement and a target of 300–500 piles per day.
The two-power-head design provides the main piling capability while giving the customer additional options for different installation requirements.
