SFS-PR-01 Sunrack TPO waterproof flexible roof solar Mounting System

1.Product Value Proposition：

SunRack TPO flexible waterproof roof is generally based on a color steel tile structure roof , mainly to solve the waterproof and aging problems, add insulation layer and TPO/PVC material layer with long life on the basis of the structural layer. The main structure of TPO waterproof roof solar bracket system (TPO base) is stainless steel + aluminum alloy, and the professional waterproof structure design allows owners to not worry about roof seepage, solving the needs of solar power station installation and roof protection.

2.Features：

1).Positioning and drilling.

2).Cleaning the holes and washing the surface.

3).Installing the supports.

4).Performing hot air welding.

5).Installing the guide rails.

3.Product Description:

Installation site	Color steel tile roof or concrete roof	Panel direction	vertical or landscape
Panel Demension	Framed solar panel for any size	Inclination	0 degree (the same angle as roof)
Wind load	60m/s	Material	Aluminum, stainless steel

4.Application Scenarios

On metal & TPO roof

Product Compatibility & Advantages:

Excellent waterproof performance:
TPO waterproof membrane is thermoplastic polyolefin waterproof membrane. It is a new type of waterproof membrane made of thermoplastic polyolefin (TPO) synthetic resin that combines ethylene propylene rubber and polypropylene using advanced polymerization technology, with antioxidants, anti-aging agents and softeners added. Polyester fiber mesh cloth can be used as internal reinforcement material to make enhanced waterproof membrane. It belongs to the synthetic polymer waterproof membrane type waterproof product.

5.Installation&Maintenance Guide

Part 1: Installation Guide

1),Base Pad Fixation
-Mark positions (1200mm longitudinal × 1000mm transverse spacing);-Weld pad edges to TPO membrane (300–350℃, 10–15cm/min speed);

test weld for no peeling ;

-Mount adjustment brackets, tighten bolts to 15 N·m; level with spirit level.
2),Rail Installation
-Cut rails to length, deburr; fix on brackets, tighten to 20 N·m
-Rail flatness deviation ≤2mm/m
3),Panel Mounting
Lift panels with suction cups; place on rails with 5–10mm gaps
Install end/mid clamps, tighten to 10 N·m (avoid over-tightening panel frames)
4),Final Inspection
Check component tightness, panel alignment
Water spray test on welds; no seepage allowed

Part Two: Daily Inspection and Maintenance

-Clean panels with soft cloth + water; avoid corrosive cleaners.
-Use original spare parts for replacement; protect TPO membrane during operation.

Safety Warnings
-No construction in bad weather; use insulated tools near electrical parts
-Do not drill TPO membrane; total load shall not exceed roof limit
-Avoid heavy pressure on aluminum rails; stack panels flat on pallets

6.FAQ – Frequently Asked Questions

Q: Can this mounting system be installed on sloped TPO roofs?
A: Yes. It is suitable for flat or low-slope roofs (≤15°) and can be fine-tuned via adjustment brackets to match roof angles.
Q: Will the installation damage the TPO roof waterproof layer?
A: No. The system adopts a non-penetrating design; base pads are fixed by hot-air welding with TPO membrane, ensuring no damage to the waterproof structure.
Q: What solar panel sizes are compatible with the system?
A: It fits mainstream panel series: Any Size (both framed and frameless).
Q: What is the warranty period of the mounting system?
A: 10-year warranty for system components, excluding damage caused by improper installation, man-made factors or extreme weather beyond design standards.
Q: Can the system withstand strong winds?
A: Yes. It complies with AS/NZS 1170 wind load standards. Adjust base pad spacing according to local wind load requirements for optimal stability.
Q: What tools are essential for routine maintenance?
A: Torque wrench, soft cleaning cloth, hot-air welder (for weld repair) and anti-scratch pads (to protect TPO membrane during operation).
