Product Features:
Non-Penetrative Design
Uses concrete ballast blocks to secure the system without damaging the rooftop waterproofing layer — ideal for roofs where penetration is not allowed.
Rail-Free Structure
PV modules are directly fixed to the front and rear legs using pre-punched bolt holes, eliminating the need for mounting rails. This reduces material costs and simplifies installation.
Flexible Ballast Configuration
Ballast blocks can be arranged according to site-specific wind load and roof bearing capacity, ensuring reliable system stability.
Quick Installation & Cost-Efficient
Fewer components and standardized design allow for rapid deployment and reduced labor cost — ideal for large-scale installations.
Main Components:
Front Leg
Pre-drilled for direct attachment to the module frame. Made from corrosion-resistant aluminum alloy or ZAM (zinc-aluminum-magnesium) coated steel.
Rear Leg
Provides tilt support and connects directly to the back of the module. Together with the front leg, it forms a stable triangular support structure.
Ballast Base Platform
Accommodates concrete blocks to fix the system in place without roof penetration. Designed for ease of installation and long-term durability.
Application Scenarios:
Flat rooftops (concrete, brick, etc.)
Heritage buildings or sites with no-drill policies
Temporary or relocatable PV systems
Industrial and commercial distributed solar projects
