Complete Guide to PV Station Drilling: How to Choose the Right PV Drilling Machine Based on Terrain?

Q1: What are the main challenges in the drilling (pile foundation pilot hole) phase of PV power station construction?

A : PV projects typically face four major challenges: 1. Complex terrain: Many projects are located in mountains, hills, and mudflats where large machinery cannot enter; 2. Variable geology: Different sites may mix soft soil, hard soil, and even tuff or granite; 3. Extremely high precision requirements: Support installation demands strict verticality and spacing of pile holes; deviation will prevent subsequent module installation; 4. Extremely tight schedules: PV projects are racing for grid connection deadlines, requiring extremely high drilling efficiency.

Q2: For different PV terrains, what "PV drilling machines" does Leili offer for combination?

A : We provide all-terrain solutions: 1. 0-30° mountains/agrivoltaics: Recommend Bracket PV Drilling Machines (lightweight, flexible,  does not damage vegetation); 2. Steep slopes over 30°/muddy ground: Recommend Crawler PV Drilling Rigs (adjustable wide tracks, strong off-road capability); 3. Small/scattered plots: Recommend Hand-push/Two-person Hand-push Drills (extreme portability, high mobility).

Q3: In PV projects with long rainy seasons like in Southeast Asia, how does the equipment overcome muddy sites?

A : For muddy and soft sand during the rainy season, we recommend Crawler PV Drilling Rigs. Equipped with widened rubber or steel tracks, they significantly reduce ground pressure to prevent sinking. The crawler chassis has strong off-road capability and, with pivot turning, can easily maneuver between narrow PV arrays. Bracket models can be manually carried to overcome impassable muddy roads.

Q4: Do your machines support customization to adapt to different countries' PV standards?

A : Absolutely. Leili is a 15-year source manufacturer and can deeply customize based on project geological reports and local standards: 1. Hole diameter and depth (adapting to different specifications of helical piles or cast-in-place piles); 2. Power systems (gasoline, diesel, pure electric, pneumatic-electric hybrid); 3. Anti-corrosion treatment (thickened anti-rust coating for coastal or high-humidity PV projects).
