Product Overview

What This Product Is

A mounting structure for solar panels on flat roofs or ground sites, made from aluminum alloy, SUS304, or PosMAC material. It is designed to be installed without roof penetrations, preserving the waterproof layer. The system supports adjustable tilt angles and is suitable for commercial and residential solar installations. It is pre-engineered for wind and snow load resistance, with a 10-year warranty and 20-year service life. The structure is easy to assemble and reduces labor costs.

Key Benefits

What You Get

Installed without roof penetrations, preserving waterproof integrity
Adjustable tilt angle to match site-specific solar exposure
Lightweight and corrosion-resistant materials for long-term durability

Designed for wind speeds up to 50m/s and snow loads up to 1.2KN/m²
Reduces labor cost with simple, tool-free assembly
Compatible with standard framed solar panels without modifications

Who It Is For

Buyers and Sites

Solar installers working on flat roof or ground-mounted projects
EPC contractors managing rooftop solar without structural modifications
Building owners who want to avoid roof leaks from penetrations
Importers supplying mounting systems to off-grid or unstable-grid markets
Residential and commercial developers requiring fast, reliable mounting

Application Scenarios

Where It Is Installed

Commercial buildings with flat roofs needing solar without roof damage
Residential homes with flat rooftops requiring a non-penetrating mounting solution
Ground-mounted solar systems in areas with high wind or snow load
Projects where rooftop waterproofing must remain intact after installation
Installations requiring quick deployment with minimal on-site labor

Problems It Solves

What This Removes From the Job

Roof leaks caused by penetrations during solar panel installation
Structural damage to flat roofs from improper mounting hardware
Inconsistent tilt angles leading to suboptimal solar yield
Lack of compatibility between mounting systems and panel frames
High labor cost from complex on-site assembly and adjustments

Technical Features

Materials

What It Is Made Of

Aluminum alloy AL6063-T5 for lightweight strength
Stainless steel SUS304 for high corrosion resistance
PosMAC material for enhanced durability and weather resistance
Anodized or double-sided magnesium aluminum alloy coated surface
Standard rail system compatible with framed solar modules

Manufacturing and Preparation

Before It Ships

Receive panel dimensions, quantity, and site requirements
Design the mounting structure using CAD drawings for custom fit
Select material and surface treatment based on environmental conditions
Fabricate the structure with precision-cut rails and brackets
Assemble and inspect the system before packing for shipment
Ship the structure with all hardware and installation instructions

Quality Control

Checked Before Packing

Verify material thickness and surface coating against specification
Check rail alignment and bracket spacing for consistent panel fit
Test structural stability under simulated wind and snow load
Confirm no sharp edges or burrs that could damage cables or panels
Inspect all hardware for correct threading and fit before packing

Customisation

What Can Be Changed at Order Stage

Adjustable tilt angle based on site-specific solar exposure
Custom design with CAD drawings for flat roof, pitched roof, soil, or cement ground
Material selection between AL6063-T5, SUS304, or PosMAC

Surface treatment choice: anodizing or magnesium aluminum alloy coating
Hardware configuration tailored to panel size and quantity

Comparison

How It Compares With the Alternatives

Penetrating roof mounts	No roof damage or waterproofing compromise, but may have lower wind resistance in extreme conditions
Fixed-angle mounting	Adjustable tilt allows better solar yield, but requires more assembly steps
Ground mounts with concrete footings	Faster installation on flat roofs, but less stability in high wind if not anchored properly
Standard rail systems without adjustment	Adjustable tilt improves energy harvest, but adds complexity to the design

Use Guide

Getting It Working on Site

Provide panel dimensions, quantity, and site conditions before ordering

Ensure the mounting structure is installed on a level, stable surface

Set the tilt angle to maximize solar exposure based on latitude and season

Secure all brackets and rails before attaching solar panels

Inspect the system after installation for loose bolts or misalignment

Maintain the structure annually to check for corrosion or loosening
