Project Case Study: 5.6MW Solar Plant in High‑Snow, Uneven Terrain
GT2 Single‑Post Ground Steel Racking System | HQ Mount
Project Overview
Location
High‑snow region, uneven mountainous terrain
Capacity
5.6 MW solar power plant
System
HQ Mount GT2 single‑post ground steel racking
Post Material
ZAM coated steel (S350GD) structure
Upper Mounting Structure
Steel solar mounting rails
Solar Foundation
Ramming piles (adjustable for uneven ground)
Design Standards
EN1991 (Eurocode) with site‑specific snow/wind loads
Completion Year
2026
Challenge
The site presented two major difficulties:
Heavy snow loads – required a robust structural design without over‑engineering
Uneven, sloped terrain – traditional two‑post systems would have required extensive ground leveling and hundreds of additional foundations
The customer needed a solution that could adapt to varying pile heights while keeping installation fast and cost‑effective.
Solution: HQ Mount GT2 Single‑Post System
Single post per m solar panel array – each array uses only one foundation, dramatically reducing earthwork and pile installation time
Adjustable solar anchor pile – multiple holes in the post allow height adjustment without rework, plus optional extra adjustable components for extreme variations
Custom engineering – our in‑house team calculated local snow loads (over 2.5 kN/m²) and designed the structure to meet Eurocode safety margins
Factory pre‑assembly test – a full mock‑up was built at our facility to ensure all parts fit perfectly before shipment
Fast‑installation clamps – patented solar mounting rail and panel fixing clamps eliminated on‑site drilling
Results & Customer Feedback
Installation time: Approximately 35% faster than a comparable two‑post system
Foundation cost: Reduced by nearly 40% (one pile per array vs. two)
Structural integrity: Passed all post‑installation load tests
Customer satisfaction: “Will use GT2 again for future projects in difficult terrain.”
Why GT2 is Ideal for High‑Snow & Uneven Terrain
Fewer foundations – less digging, less concrete, less time
Height flexibility – each post can be adjusted independently to match ground slope
ZAM steel durability – 2‑6x better corrosion resistance than standard galvanization (SGS 4000H tested)
Engineered for heavy loads – custom calculations ensure safety without over‑specification
Pre‑tested delivery – no surprises on site
