Product Description

Product Description

HDG Painted Steel Single Axis Solar Racking System is a single axis solar tracking system designed for harsh environments. It adopts the hot dipped galvanisation (HDG) + multi-layer spray anti-corrosion process to provide excellent corrosion resistance and structural strength, and is suitable for ground-mounted power stations, agricultural photovoltaic and high humidity/high salt spray scenarios. The system dynamically optimises the angle of the PV panels through single-axis tracking technology, increasing the power generation efficiency by 25%-35%, combining durability with high return, making it an ideal choice for large-scale PV projects.

1.Super anti-corrosion performance

Double protection: hot-dipped galvanised base material (zinc layer ≥85μm, compliant with ISO 1461) + epoxy resin primer + polyurethane topcoat spraying, passes 4,000 hours salt spray test (ISO 9227), adapts to highly corrosive environments such as coasts and industrial zones (C5M grade).
Weather Resistance: Resistant to UV rays, acid rain (pH 3-11) and sand erosion, service life ≥ 30 years.

2. Heavy-duty structural design

High-strength steel main beam: wind load resistance up to 60m/s (Class 14 typhoon), snow load 5800Pa, certified by IEC 62817.
Single-axis tracking load-bearing: 7 tonnes load-bearing for a single group of brackets, compatible with double-glass, 210mm oversized modules and double-sided power generation technology.

3. High-efficiency power generation performance

**±45° Intelligent Tracking**: Dynamically adjusts the angle based on light-sensing sensors and AI algorithms, increasing average daily power generation by more than 30%.
Double-sided module optimisation: adjustable height of 1.5m-3.5m above the ground, backside power generation gain increased by 15%-20%.

4. Fast installation and low maintenance

Modular pre-assembly design: 40% reduction in on-site construction time, suitable for helical piles, concrete foundations and ballast solutions.
Self-lubricating bearings + hydrophobic coating: annual maintenance cost is less than 0.8% of power generation gain, and automatically resets to a safe angle after a disaster.

5. Environmental protection and economy

95% Material Recycling: 35% lower carbon footprint for production, meets EPD environmental certification.
Fast ROI: Payback period <4 years, LCOE (cost of kilowatt-hour) as low as $0.023/kWh.

Installation and Maintenance Guide
Installation steps

Foundation construction: Select the type of pile foundation according to the geological load (recommended helical pile torque ≥4500N-m), horizontal error ≤1.5°.
Bracket assembly:
Main beam and column bolt fastening torque 70N-m±5%, guide rail spacing to suit the component width (error ±1mm).
Drive system integration:
Installation of IP68 protection motor, connection of light sensor and PLC controller, calibration of tracking zero point (accuracy ±0.5°).
Test high wind reset response (wind speed ≥18m/s automatically switch to 25° wind angle, delay <2 seconds).
Maintenance Recommendations

Quarterly inspection: clean track debris, check bolt anti-loosening marking, repair damaged coating (provide special paint repair tool).
Annual maintenance: lubricate bearings (high-temperature resistant lithium grease), update control software, test grounding resistance (≤4Ω).
Post-disaster treatment: check structural deformation after typhoon/sandstorm, reset bracket to safe mode.

 

 

Typical Application Scenarios
Large ground power station: desert, Gobi, mudflat and other 100 MW level projects.
Agricultural/fishery photovoltaic complementary: height-adjustable bracket, compatible with crop cultivation or aquaculture.
Coastal photovoltaic system: salt spray resistant design, suitable for harbours, islands and other offshore areas.
Distributed power generation in industrial areas: energy replacement solutions for chemical plants, oil refineries and other highly polluted areas.
Off-grid energy storage project: paired with lithium battery system to achieve stable power supply in remote areas.

FAQ

 

Q1: What is the difference between HDG+Painted process and normal galvanising?

A: HDG (Hot Dipped Galvanising) provides basic corrosion protection and the Painted process further insulates against corrosive media. The double protection lasts up to 3 times longer than ordinary galvanising and supports customisation of RAL colour cards (e.g. RAL 7021 Industrial Grey).

Q2: Is the system compatible with double-sided modules and tracking links?

A: It is fully compatible! The height and inclination of the bracket are adjustable, and the tracking angle is dynamically optimised by combining the double-sided rate data, with a backside gain of up to 25%.

Q3: How reliable is the system in high desert temperatures?

A: The drive components are designed to withstand high temperatures (-40ºC~85ºC), and the bearings have passed the ASTM G154 UV aging test, with a daily attenuation rate of <0.01% in a 60ºC environment.

Q4: Does maintenance require a professional?

A: AR remote guidance tool is provided. Scanning the QR code of the parts can obtain 3D disassembly and assembly guidelines, and 90% of the operations can be completed by ordinary O&M personnel.

Q5: What are the warranty and after-sales terms?

A: We offer a 15-year warranty on the main structure, an 8-year warranty on the drive system, a 72-hour global emergency response, and free lifetime coating repair support.
