Project Case Study: 5.6MW Solar Plant in High‑Snow, Uneven Terrain

GT2 Single‑Post Ground Steel Racking System | HQ Mount

Project Overview

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
