Tammy Renewable Carport Waterproofing System

In solar carport projects, waterproofing and drainage performance are critical factors that directly impact the durability, safety, and long-term reliability of the structure. Unlike conventional rooftop solar installations, where photovoltaic (PV) modules are added to an existing roof with its own waterproofing layer, solar carports require the PV modules themselves to serve as part of the roof covering. As a result, the waterproofing system must be integrated into the structural design from the very beginning.

Traditional rooftop PV projects are typically retrofit installations. The original roof already provides weather protection and waterproofing, while the solar panels are mounted above it. In contrast, a solar carport relies on the PV modules to function as the roof surface, making it essential to effectively manage rainwater, snow accumulation, and extreme weather conditions.

To address drainage challenges, conventional metal roofs often use corrugated profiles to channel water away efficiently, while tiled roofs rely on overlapping tile arrangements to guide rainwater flow.

Tammy Renewable carports can be equipped with a professional structural waterproofing system specifically designed for photovoltaic applications. The system consists of both longitudinal and transverse drainage channels that work together to provide reliable waterproofing and efficient water management.

 

Since PV modules create a relatively smooth roof surface, heavy rainfall can generate significant drainage pressure. To address this issue, Tammy Renewable incorporates a specially designed steel "M-shaped drainage channel" beneath the long edges of the modules where the clamping system is installed. This channel efficiently collects and directs rainwater away from the roof surface. In addition, secondary drainage channels are installed along the short edges of the modules, creating a comprehensive drainage network.

The M-shaped drainage channels are installed parallel to the structural beams and designed with a specific slope to facilitate smooth water flow. At the end of each channel, a collection pipe gathers and discharges the rainwater in a controlled manner, preventing water accumulation and enhancing the structural integrity and longevity of the carport.

To meet different project requirements, Tammy Renewable offers two waterproofing structure options. The first utilizes steel drainage channels secured to the purlins with self-drilling screws. This solution provides a robust and proven waterproofing structure suitable for a wide range of applications.
For customers seeking enhanced aesthetics and corrosion resistance, Tammy Renewable also offers an upgraded aluminum waterproofing system. This design uses specially engineered aluminum clips to connect the drainage components to the purlins, creating a cleaner and more refined appearance while maintaining excellent structural performance.
The aluminum drainage system features optimized dimensions and larger water-flow capacity, allowing it to effectively handle heavy rainfall as well as large volumes of melting snow during winter conditions. This ensures reliable drainage performance even in challenging climates.
