🔑Key Features

• Adjustable Tilt Design
  Allows flexible tilt angle adjustment to maximize solar power generation based on site conditions.

• High-Strength Aluminum Construction
  Made from premium aluminum alloy for lightweight handling, high structural strength, and corrosion resistance.

• Front Leg & Rear Leg Configuration
  Designed to work together for stable and balanced support in adjustable tilt solar mounting systems.

• Easy and Fast Installation
  Pre-drilled holes and simple structure reduce installation time and labor costs on-site.

• Compatible with Metal Roof PV Systems
  Suitable for trapezoidal metal roofs, standing seam roofs (with proper clamps), and flat roof installations.

Tools & Materials Required

• Adjustable tilt mounting system (front legs, rear legs, rails, fasteners)

• Solar modules

• Drill and torque wrench

• Measuring tape and level

• Stainless steel fasteners (SUS304 or equivalent)

• Waterproof sealant (for metal roof installations)

• Concrete anchors or ballast blocks (for concrete roofs)

Part 1: Installation on Metal Roof

Step 1: Roof Inspection & Layout Marking

• Confirm roof structure and load capacity.

• Identify purlin positions or structural supports.

• Mark the mounting points according to the module layout and tilt angle design.

Step 2: Fix Roof Attachments

• Install L feet, roof clamps, or base plates directly onto the metal roof.

• Secure fasteners into purlins or structural beams.

• Apply waterproof sealing around all penetrations to prevent leaks

Step 3: Install Rear Legs

• Attach the rear legs to the roof attachments.

• Ensure all rear legs are aligned and vertically plumb.

• Lightly tighten bolts to allow adjustment.

Step 4: Install Front Legs

• Fix the front legs in front of the rear legs according to the system design.

• Adjust the front leg height to achieve the required tilt angle.

• Check angle consistency across all mounting points.

Step 5: Install Rails

• Connect mounting rails between front and rear legs.

• Ensure rails are straight, level, and securely fixed.

• Tighten all structural bolts to specified torque values.

Step 6: Mount Solar Panels

• Place solar modules onto the rails.

• Secure modules using mid clamps and end clamps.

• Ensure proper grounding and electrical clearances.

Step 7: Final Inspection

• Verify tilt angle, fastener torque, and system stability.

• Confirm waterproofing integrity.

• Perform a pull and vibration check.

Part 2: Installation on Flat Concrete Roof

Step 1: Site Preparation

• Clean the roof surface and confirm slope and drainage conditions.

• Check structural load capacity and wind uplift requirements. 

Step 2: Fix Base Supports

Two common methods are used:

Option A: Anchored Installation

• Drill holes into the concrete roof.

• Install expansion bolts or chemical anchors.

• Fix base plates securely to the concrete surface.

Option B: Ballasted Installation

• Place ballast blocks according to the system design.

• Ensure even weight distribution and anti-slip protection.

Step 3: Install Rear and Front Legs

• Secure rear legs to the base supports.

• Install front legs and adjust height to achieve the designed tilt angle.

• Ensure all legs are aligned and evenly spaced.

Step 4: Install Rails

• Connect rails between front and rear legs.

• Ensure correct row spacing to avoid inter-row shading.

• Fully tighten all bolts after final alignment.

Step 5: Mount Solar Panels

• Place modules on rails and fix with clamps.

• Maintain recommended module spacing for thermal expansion.

Step 6: System Check

• Verify mechanical stability under wind and load conditions.

• Confirm tilt angle and array alignment.

• Perform final torque and safety checks.

Recommended Tilt Angle

• Latitude-based optimization (typically 10°–30° for flat roofs)

• Adjust according to seasonal performance or project design

Installation Tips

• Always follow local building codes and wind load standards.

• Use stainless steel fasteners for corrosion resistance.

• Do not overtighten aluminum components.

• Ensure proper grounding and bonding of the system.
