Module Types: EcoX is certified to be installed with standard framed 60 cell
modules according to the approved module list.
Mechanical Loading: EcoX is certified to UL2703 for mechanical loading.
Tested modules are listed in Appendix D. Span requirements for a given
jobsite can be determined using the EcoX Estimator design tool:
Fire Testing: EcoX is certified to UL2703/1703 Fire Resistance Standard with
the following requirements:
lInstructions in this guide must be followed.
lThe EcoX system must be mounted over a fire resistant roof covering rated
for the application.
lModules may be installed in landscape or portrait
lThe EcoX fire rating is valid with or without a skirt.
lAll height settings of EcoX product are valid, up to highest setting
(corresponds to 4 ¼” from roof surface to lower edge of module frame).
For pitches greater than 2:12 (9.46 degrees):
lEcoX is certified to Class A with Type 1 and 2 modules.
lJunction box must be mounted away from the roof downhill edge.
For pitches less than 2:12 (9.46 degrees), aka “flat“ or “low-slope“ roofs:
lEcoX is certified to Class A with Type 1 modules.
lJunction box can be mounted at any location.
Grounding and Bonding: EcoX is certified to UL2703 for grounding and
bonding. The grounding and bonding test evaluates EcoX as a system with
approved modules. When installed per the requirements outlined in this
installation guide, EcoX with approved modules are rated as a system to
create a continuous bonded structure.
Installation Requirements: This install guide officially documents the
components used and proper methods for an EcoX installation. Bonding
elements are incorporated into EcoX components. As the system is built on
the roof, components and modules are bonded together. Specific steps to
ensure a bonded system are described through the installation guide. It is the
installer's responsibility to ensure that the system is safely and properly
installed, and that the system is bonded back to a final ground point. There
are no specific array size limitations due to the flexible and expandable design
of EcoX.
UL2703 System Documentation: To document the UL2703 system rating, a
label is factory-applied to the end of each skirt. For skirt-less configuration, a
label is factory-applied to the side of the End Clamp assembly. Below is an
example of the label:

EcoX General Application Notes
System Design and Span Requirements: EcoX is designed to flush-mount
photovoltaic modules on pitched roofs as described in this guide. The span
between attachment locations depends on the module, the site conditions,
and the system layout.
Site Specific System Design: The EcoX Estimator is a powerful system design
tool. The user inputs all site conditions and can layout multiple roof surfaces.
The EcoX Estimator outputs a site specific design package with engineering
specs and bill of materials.
Visit the EcoX Estimator at to
layout your array and instantly obtain attachment spacing, bill of materials,
and engineering analysis.
Roof Type: EcoX is designed to mount photovoltaic modules to a range of roof
surfaces, including :
Asphalt or composite shingles
Concrete or clay tiles (see Addendum )
Membrane roof
Metal roofs are permitted as long as the method of bonding and grounding
the metal roof is approved by AHJ. Contact Ecolibrium Solar if your project’s
roof surface type is metal, or not listed above.
Wind Zone: EcoX is designed to mount photovoltaic modules on pitched roof
surfaces in areas with extreme wind conditions. Please contact Ecolibrium
Solar if your project's wind speed exceeds the zone allowable in the EcoX
Estimator.
Roof Height: EcoX is designed to mount photovoltaic modules on pitched roof
surfaces with a mean roof height up to 60 feet. Please contact Ecolibrium
Solar if your project's mean roof height exceeds 60 feet.
Roof Pitch: EcoX is designed to mount photovoltaic modules on roof surfaces
between 0 and 90 degrees from horizontal.
Roof Zones: EcoX is designed to mount photovoltaic modules on pitched roof
surfaces in all roof zones with attachment spacing as prescribed in the EcoX
Estimator.
Roof Orientation: Throughout this manual, “downhill” is used to reference
the direction of the lower or leading edge of the array, and “uphill” is used to
reference the direction of the trailing or back edge of the array.
EcoX Certifications
Approved Modules: This racking system may be used to ground and/or
mount a PV module complying with UL 1703 only when the specific module
has been evaluated for grounding and/or mounting in compliance with the
included instructions. Specific modules included in EcoX certifications are
documented in Appendix D at the end of this install guide.
