Installation Guide_PV-ezRack ComT V2.0 (September 2020)
Planning
This document provides sufficient information for the PV-ezRack
®
ComT™ system installation up to
heights of 30 meters. If your installation site is more than 30 meters high please contact Clenergy to
obtain project specific engineering certificate to support your installation.
2.4 Determine the Height of the Installation Site
The PV-ezRack
®
ComT™ system is fixed 10° tilt system
2.5 Determine System Tilt Angle
The PV-ezRack
®
ComT™ system can be used for roof slopes up to 30°. Please verify that the
Installation site roof slope is between 0° and 30°.
2.6 Determine Roof slope
Please refer to PV-ezRack
®
ComT™ Interface Spacing Table in Certification Letter.
2.7 Determine the Installation Area of Roof
Please verify rafter/purlin properties of building, which could affect the interface spacing. For example,
tin interface spacing on the metal purlin in the certification letter is based on steel purlin G450 1.5
mm thick. If the steel purlin is less than 1.5 mm thick, the corresponding reduction factor of interface
spacing will be applied. Please refer generic notes for details.
2.8 Verify Rafter/Purlin Properties of Building
Please refer to the Certification Letter and Interface Spacing Table. If a project specific Certification
Letter has been provided, please refer to the support spacing in this letter.
2.9 Determine the Maximum Rail Support Spacing
Rail end overhang should be not over 40% of the interface spacing. For example, if the interface
spacing is 1500mm, the Rail end overhang can be up to 600mm only.
2.10 Verify Maximum Rail End Overhang
It is recommended to acquire PV modules clamping zone info. from PV modules manufacturer, which
can help to plan interfaces positions on the roof and rails orientation and positions.
2.11 Acquire PV Modules Clamping Zone Information
