1.1.This practice details the minimum requirements for installation, commissioning, operations and maintenance process to ensure safe and reliable power generation for the expected life of the photovoltaic power plant. Specifically dealing with commercial photovoltaic installations, this practice covers a broad spectrum of designs and applications and shall be focused on proper process to ensure quality. 1.2.This practice does not cover the electrical aspects of installation. 1.3.This practice shall not dictate specific design criteria or favor any product or technology. 1.4.This practice shall be focused on the proper, documented process required to build and operate a quality PV plant. 1.5.Integration of best practices shall be relevant to this standard and promote a mechanism for rapid evolution and reaction to changes or events. Sandia Labs has an existing process mechanism that will be studied as a model though others may be adopted as acceptable mechanisms. 1.6.The standard shall be divided into three key areas: 1.6.1.Design, engineering and construction of the PV plant. Further subdivisions may be addressed for building integrated, building mounted and ground mount systems. 1.6.2.Commissioning, testing and approval for power generation. Standards for owner acceptance will also be addressed. 1.6.3.Operating and Maintenance of the PV plant including performance monitoring, periodic inspection, preventive maintenance and periodic re-commissioning. 1.7.Safety 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. 1.8.This practice provides guidelines for minimum process required and must be used in conjunction with applicable codes and standards, AHJ requirements, manufacturer requirements and best practices. 1.9.This practice is not intended to replace or supersede any other applicable local codes, standards or Licensed Design Professional instructions for a given installation. 1.10.This 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 appro- priate safety and health practices and determine the applica- bility of regulatory limitations prior to use.

The rapid growth of the renewable generation market in the U.S. has left gaps between code compliance and best practice. Best practices are rapidly evolving utilizing lessons learned from a variety of sources and this is particularly true for solar. Many industry groups have created efforts to study and improve industry practices though no consistent, connected effort exists. Further, the insurance and capital markets need consistent and bankable products to reduce the risk profile and related costs. The purpose of this ASTM effort is to create a standard for the ICOMP process of solar PV plants that will allow for higher confidence from capital markets and insurance underwriting with the goal of lower industry costs. These goals are consistent with the DOE SunShot initiative to reach $1.00 per watt installed and provide capability for the industry beyond the scheduled ITC expiration.Back to Top
