This Interpretation of Regulations (IR) describes the Division of the State Architect (DSA) requirements for review and approval of solar systems (see Definitions) used in construction projects under the jurisdiction of DSA. This IR clarifies the requirements for structural support of solar. In addition to referencing international electro-technical photovoltaic standards such as IEC 61215, IEC 61646 and IEC 61730, typical standards from the building sector are also included, such as: EN 13501 (Safety in case of fire); EN 13022 (Safety and accessibility in use); EN 12758 (Protec-tion. There are numerous national and international bodies that set standards for photovoltaics. There are standards for nearly every stage of the PV life cycle, including materials and processes used in the production of PV panels, testing methodologies, performance standards, and design and. What are the requirements for regulating PV system design and battery function? First,to regulate system design and battery function: IEC 62124for stand-alone PV design recommendations and PV performance evaluation (including battery testing and recovery after periods of low state-of-charge) in a. e attachments are not within bands of strength. t Guidelines (the Guidelines), also called “Step 1: Structural PV Array Mounting Requirements Checklist” (the “Checklist”).
