IronRidge systems have been fully listed to the UL 2703 standard by Intertek Group plc. UL 2703 is the standard for evaluating solar mounting systems. It ensures these devices will maintain strong electrical and mechanical connections over an extended period of time in extreme outdoor environments.
There are three types of approval that a racking manufacturer can achieve, with listed being the highest level:
IronRidge has passed electrical, mechanical, and fire testing in order to achieve its UL 2703 listing.
The IronRidge listing covers modules, rails, and attachments. This means that the module frames and IronRidge racking are considered an electrically continuous system, requiring fewer jumpers and lugs.
The UFO has been tested to re-tighten a minimum of five times.
Alternative bonding jumpers are not included within the UL 2703 listing. Use of these products may cause concern with the Authority Having Jurisdiction (AHJ), and could lead to a failed inspection.
The UL 2703 certification process includes extensive testing of the IronRidge components with the module. These tests are identical to the tests performed in the module listing process (UL 1703). As a result, the UL 2703 listing covers both products, not just the mounting components.
The IronRidge System does not harm the module, but you should always confirm warranty questions with the manufacturer before installing.
The UL 2703 certification process included extensive environmental and corrosion testing. The high quality stainless steel used in the IronRidge UFO does not cause significant galvanic corrosion, even in extreme environments.
The following devices have been tested/evaluated for bonding in the Flush Mount, Tilt Mount and Ground Mount systems. The new microinverter kit (MI-BHW) bonds the following devices to XR Rails:
If your device is not listed here, you can still use the kit to mount the device to the rail. However, this requires providing an alternate means to ground each device.
Approved Enphase microinverters (M250-72, M250-60, M215-60, C250-72) can provide equipment grounding of all IronRidge systems, eliminating the need for grounding lugs and field installed equipment ground conductors (EGC). A minimum of two microinverters mounted to the same rail and connected to the same Engage cable is required.
Refer to installation manuals for additional details.
FlashFoot2 comes with an industry-leading 20 year warranty.
FlashFoot2 can be installed on composition shingle roofs with a pitch of 2:12 to 12:12 (9-45 degrees).
FlashFoot2 comes with a structural certification letter. This provides lateral and uplift capacity for the product, as well as details on testing.
Yes, FlashFoot2 conforms to UL 2703's Mechanical and Bonding requirements. The entire Flush Mount System's UL 2703 listing can be found on page 3 of the installation manual.
FlashFoot2 passed both UL 441 Section 27 "Rain Test" and TAS 100-95 "Wind Driven Rain Test" standards, making it the most reliable and robust attachment on the market. The UL 441 "Rain Test" is equivalent to the rain testing done in an IAPMO evaluation.
Place Cap onto flashing in the desired orientation for E/W or N/S rails, then rotate 180 degrees. An audible click will confirm that the Cap has been properly installed and is now locked into place.
No. If the attachment hardware is correctly tightened, it will prevent the rail from pulling out. Additionally, a constriction at the top of the Cap's slot stops loose hardware from slipping out.
IronRidge is separating out the bonding hardware from the attachment kits (FlashFoot2 and Slotted L-Foot) in order to give installers the flexibility to choose between square and T-bolt, based on their preference.
New language in the 2012 IBC states that a roof mounted photovoltaic system must have the same fire classification as the roofing material the system is installed upon.
2012 IBC: 1509.7.2 Fire classification. Rooftop mounted photovoltaic systems shall have the same fire classification as the roof assembly required by Section 1505.
The system specified in the code includes the roof covering material, PV mounting system and PV modules. Together all three are tested to determine the system fire rating.
Fire Classification refers to a fire-resistance rating system for roof covering materials based on their ability to withstand fire exposure.
the general requirement for roofing systems in the ibc refers to a class c fire rating. class a or b is required for areas such as wildland urban interface areas (wui) and for very high fire severity areas. many of these areas are found throughout the western united states. california has the most class a and b roof fire rating requirements, due to wild fire concerns.
All fire rated roofing materials are covered within this certification including composition shingle, clay and cement tile, metal, and membrane roofs. The testing is conducted on a basic roof design that represents all listed fire rated roof constructions.
The IronRidge Class A rating will not diminish the fire rating of the roof, whether Class A, B or C.
The new UL1703 standard with the updated fire test introduces the concept of a PV module Type that is based on 4 construction parameters and 2 fire performance parameters. The purpose of this classification is to certify a mounting system without having to test it with every module.
Attachments and their respective flashings are not constituents of the rating at this time. All code-compliant flashing methods are acceptable from a fire rating standpoint.
Clamps are considered part of the PV "system", and are covered in the certification.
No, IronRidge achieved a Class A fire rating without any additional racking components.
UL fire testing was performed with a gap of 5", which is considered worst case in the standard. Therefore, the rating is applicable to any module to roof gap.
IronRidge is currently Class A certified for Flush Mount applications parallel to roof with Type 1 and 2 modules. Tilt Mount systems are certified with Type 1 modules.
Generally, older roofs will typically be "grandfathered in", and will not require re-roofing. However, if 50% or more of the roofing material is replaced for the solar installation the code requirement will be instated.
Every jurisdiction enforces their own requirements related to fire setbacks for rooftop solar, and these requirements are not related to the fire rating of the system.
