Engineered for high structural reliability, rapid field installation, and resilience in extreme low-temperature environments.
Strategic deployment of structural solar racking in Mongolia’s premier industrial and mining hub.
Erdenet stands as one of Northern Mongolia's central economic engines, dominated by massive copper and molybdenum mining infrastructure. Transitioning auxiliary facilities, tailing management operations, and heavy machinery workshops to solar energy requires high-durability racking built for intense daily load requirements.
Located at approximately 1,280 meters above sea level in Orkhon Province, Erdenet experiences over 2,700 hours of bright sunshine annually. High atmospheric clarity offers exceptional photovoltaic yield potential, provided structural systems can maintain optimal tilt angles despite heavy snow accumulation.
With winter temperatures dropping to -38°C and intense seasonal freeze-thaw cycles, standard solar brackets often suffer structural fatigue or foundation uplift. Specialized engineering with hot-dip galvanization (HDG) and low-temperature ductile alloys is paramount.
An in-depth technical examination of foundation mechanics, wind lift forces, and material science for northern Mongolian photovoltaic deployments.
In Erdenet, seasonal frost penetration can extend down to 2.5–3.0 meters. As soil moisture freezes, vertical expansive forces exert massive uplift pressure on traditional concrete pad foundations, resulting in uneven alignment and micro-cracking across solar PV modules.
Our engineered Ground Screw Anchor Foundations utilize high-tensile Q235B/Q355B continuous-threaded steel shafts driven below the localized frost penetration depth. The helical threads convert vertical frost uplift into shear forces distributed along the deep frozen ground layer, guaranteeing zero foundation displacement during seasonal thaw cycles.
Standard structural carbon steels experience a Ductile-to-Brittle Transition Temperature (DBTT) when subjected to subarctic conditions. Under violent winter wind gusts, brittle structural components risk sudden yield failure.
Dongguan Soltrux Solar utilizes high-purity AL6005-T5 anodized aluminum alloys for roof brackets and normalized structural steel with controlled manganese-to-carbon ratios for ground frames, ensuring high Charpy V-notch impact toughness even at -40°C.
Open Mongolian steppe terrain exposes ground-mounted solar arrays to severe, laminar wind currents exceeding 160 km/h. Concurrently, heavy snow build-up can impose dead loads exceeding 1.5 kN/m².
Our mounting configurations feature variable tilt dynamics (35° to 55°), optimizing winter solar incidence angles while facilitating natural gravity-driven snow shedding. Finite Element Analysis (FEA) modeling guarantees structural deflection parameters remain well within ISO and Eurocode 1 safety boundaries under maximum combined snow and wind loading conditions.

Tailored structural configurations designed for municipal, mining, pastoral, and commercial sector integrations.
Deploying heavy ground screw racking arrays alongside mining roads, copper processing facilities, and administrative quarters to reduce reliance on heavy industrial diesel generators and supplement high grid electricity consumption.
Elevated tripod and high-clearance pole mounting structures allow dual land usage. Pastoral livestock can utilize solar arrays for wind shelter while generating off-grid microgrid power for water pumping and rural heating systems.
Erdenet's commercial warehouses and heating plant structures often feature trapezoidal sheet metal or tile roofing. Stainless steel roof brackets, roof clamps, and light-weight aluminum U-profiles offer non-penetrative, waterproof mounting.

Our dual-axis tracking and adjustable tilt mechanisms utilize specialized synthetic self-lubricating polymer bushings that operate without grease breakdown down to -50°C, eliminating freeze-lock risks inherent in standard mechanical joints.
Technical guidance for EPC project developers, procurement officers, and solar installers operating in Erdenet.
Deep ground screws eliminate the need for costly subarctic concrete pouring, which requires heated curing enclosures below freezing. Screws anchor directly into stable soil layers beneath the 2.5m frost heave zone, providing immediate load-bearing stability without curing delays.
Our structures feature galvanization layers exceeding 85 µm (and up to 100 µm upon request), conforming to ISO 1461 standards. This thick metallurgical zinc barrier protects against atmospheric corrosion, high UV radiation, and abrasive wind-blown dust typical of the Mongolian steppe.
Given Erdenet's latitude (~49° N), a fixed optimal annual tilt angle ranges between 40° and 45°. However, utilizing our adjustable tripod or tracker systems to increase winter tilt to 50°-55° sheds heavy snow automatically while capturing low-horizon winter sunlight.
