Published date

01-04-2019

1.1This practice details minimum requirements for the installation of roof mounted photovoltaic arrays on steep-sloped roofs with water-shedding roof coverings. These requirements include proper water-shedding integration with the roof system, material properties, flashing of roof penetrations, and sufficient anchoring per regional design load requirements.

1.1.1This practice does not apply to building-integrated or adhesively attached photovoltaic systems that are applied as roof-covering components.

1.2This practice does not cover the electrical aspects of installation.

1.3Installation considerations are divided into two distinct aspects: the interface between the photovoltaic module and the array mounting structure, and the interface between the array mounting structure and the roof or roof structure.

1.4Safety and hazard considerations unique to this application, such as worker fall protection, electrical exposure, accessibility of modules, and roof clearance around the perimeter of the array are addressed by other codes, standards, or authorities having jurisdiction.

1.5This practice is intended to provide recommended installation practices for use by installers, specifiers, inspectors, or for specification by photovoltaic module manufacturers.

1.6This practice provides minimum guidelines and should be used in conjunction with module and mounting system manufacturers’ instructions. This practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM Standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. The word “Standard” in the title means only that the document has been approved through the ASTM consensus process.

1.7This practice is not intended to replace or supersede any other applicable local codes, standards or Licensed Design Professional instructions for a given installation.

1.8This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazards are given in Section 8.

1.9This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
