Solar Solutions for Low-Pitch Roofs with TPO Membranes

Installing solar panels on a low-pitch roof with a TPO (thermoplastic polyolefin) membrane requires a tailored approach to ensure efficiency and durability. These roofs, often compared to flat roofs, benefit from specialized, non-penetrating mounting systems.

This roof has a low pitch sealed with a thermoplastic polyolefin (TPO) membrane for which the racking solution is similar to flat roofs.

Our Process:

Non-Penetrating Racks: We use EcoFoot 2+ ballasted, basket-style racks to securely hold the solar array without penetrating the roof membrane.
Stability Anchors: For added safety, we install roof anchors on the lower side to prevent the array from shifting downhill due to snow or wind. In this project, just four sealed roof anchors were required to meet building codes.
Extra Reinforcement: A cross-strut system holds the last row of panels firmly in place, ensuring long-term stability.

With this method, your solar system remains secure and functional, even in challenging weather conditions.

The roof anchor and cross-strut hold the last row of the solar array firmly to this low-pitched roof.
