The calculations produced are only for the roof framing supporting the proposed PV installation referenced in the stamped planset and were completed according to generally recognized structural analysis standards and procedures, professional engineering and design experience, opinions and judgements. Existing deficiencies which are unknown or were not observable during time of inspection are not included in this scope of work. All PV modules, racking, and mounting equipment shall be designed and installed per manufacturer's approved installation specifications. The Engineer of Record and the engineering consulting firm assume no responsibility for misuse or improper installation. This analysis is not stamped for water leakage. Framing was determined based on information in provided plans and/or photos, along with engineering judgement. Prior to commencement of work, the contractor shall verify the framing sizes, spacings, and spans noted in the stamped plans, calculations, and cert letter (where applicable) and notify the Engineer of Record of any discrepancies prior to starting construction. Contractor shall also verify that there is no damaged framing that was not addressed in stamped plans, calculations, and cert letter (where applicable) and notify the Engineer of Record of any concerns prior to starting construction. 522 S Raitt St Unit# 210/4/2024 Expedited Permit Process for PV Systems 1 Expedited Permit Process for PV Systems Standard String System The Solar America Board for Codes and Standards (Solar ABCs) Expedited Permit Pro- cess provides a means to differentiate systems that can be permitted quickly and easily due to their similarity with the majority of small-scale PV systems. Those systems with unique characteristics may be handled with small additions to this Expedited Permit Process or may require much more information, depending on the uniqueness of the installation. The following pages contain forms for the Standard String System to use with the Expe- dited Permit Process. The Micro-Inverter, AC Module, and Supply-Side Connection forms are also available as interactive PDF files at www.solarabcs.org/permitting. In jurisdic- tions that have adopted the Expedited Permit Process for PV Systems, these forms can be filled out electronically and submitted in either printed form and via email. An elec- tronic format is used so that the supplied information is standardized and legible for the local jurisdiction. 522 S Raitt St Unit# 210/4/2024 Expedited Permit Process for PV Systems 2 Expedited Permit Process for Small-Scale PV Systems Standard String System The information in this guideline is intended to help local jurisdictions and contractors identify when PV system installations are simple, needing only a basic review, and when an installation is more complex. It is likely that 50%-75% of all residential systems will comply with these simple criteria. For projects that fail to meet the simple criteria, resolution steps have been suggested to provide as a path to permit approval. Required Information for Permit: 1. Site plan showing location of major components on the property. This drawing need not be exactly to scale, but it should represent relative location of components at site (see supplied example site plan). PV arrays on dwellings with a 3’ perimeter space at ridge and sides may not need separate fire service review. 2. Electrical diagram showing PV array configuration, wiring system, overcurrent protection, inverter, disconnects, required signs, and ac connection to building (see supplied standard electrical diagram). 3. Specification sheets and installation manuals (if available) for all manufactured components including, but not limited to, PV modules, inverter(s), combiner box, disconnects, and mounting system. Step 1: Structural Review of PV Array Mounting System Is the array to be mounted on a defined, permitted roof structure? l Yes l No If No due to non-compliant roof or a ground mount, submit completed worksheet for the structure WKS1. Roof Information: 1. Is the roofing type lightweight (Yes = composition, lightweight masonry, metal, etc…)__________________________ ____________________________________________________________________________________________________ If No, submit completed worksheet for roof structure WKS1 (No = heavy masonry, slate, etc…). 2. Does the roof have a single roof covering? l Yes l No If No, submit completed worksheet for roof structure WKS1. 3. Provide method and type of weatherproofing roof penetrations (e.g. flashing, caulk).____________________________ Mounting System Information: 1. Is the mounting structure an engineered product designed to mount PV modules with no more than an 18” gap beneath the module frames? l Yes l No If No, provide details of structural attachment certified by a design professional. 2. For manufactured mounting systems, fill out information on the mounting system below: a. Mounting System Manufacturer ___________Product Name and Model#________________________________ b. Total Weight of PV Modules and Rails ___________lbs c. Total Number of Attachment Points____________ d. Weight per Attachment Point (b÷c)_________________lbs (if greater than 45 lbs, see WKS1) e. Maximum Spacing Between Attachment Points on a Rail ______________inches (see product manual for maximum spacing allowed based on maximum design wind speed) f. Total Surface Area of PV Modules (square feet)_________________ ft2 g. Distributed Weight of PV Module on Roof (b÷f)_______________ lbs/ft2 If distributed weight of the PV system is greater than 5 lbs/ft2, see WKS1. Step 2: Electrical Review of PV System (Calculations for Electrical Diagram) In order for a PV system to be considered for an expedited permit process, the following must apply: 1. PV modules, utility-interactive inverters, and combiner boxes are identified for use in PV systems. 2. The PV array is composed of 4 series strings or less per inverter. 3. The total inverter capacity has a continuous ac power output 13,440 Watts or less 4. The ac interconnection point is on the load side of service disconnecting means (690.64(B)). 5. One of the standard electrical diagrams (E1.1, E1.1a, E1.1b, or E1.1c) can be used to accurately represent the PV system. Interactive PDF diagrams are available at www.solarabcs.org/permitting. Fill out the standard electrical diagram completely. A guide to the electrical diagram is provided to help the applicant understand each blank to fill in. If the electrical system is more complex than the standard electrical diagram can effectively communicate, provide an alternative diagram with appropriate detail. 522 S Raitt St Unit# 210/4/2024 E x p e d i t e d P e r m i t P r o c e s s f o r P V S y s t e m s 3 Standard String System Site Plan               522 S Raitt St Unit# 210/4/2024 E x p e d i t e d P e r m i t P r o c e s s f o r P V S y s t e m s 4 Standard String System Electrical Diagram                                                                             6 6                                       522 S Raitt St Unit# 210/4/2024 E x p e d i t e d P e r m i t P r o c e s s f o r P V S y s t e m s 5 Notes for Standard String System Electrical Diagram Contractor Name, Address and Phone: _________________ _________________ _________________ _________________ Notes for One-Line Standard Electrical Diagram for Single-Phase PV Systems Site Name: __________________________ Site Address: ________________________ System AC Size: ______________________ SIZE FSCM NO DWG NO REV SCALE NTS Date:SHEET Drawn By: Checked By: MAX POWER-POINT CURRENT (IMP) MAX POWER-POINT VOLTAGE (VMP) OPEN-CIRCUIT VOLTAGE (VOC) SHORT-CIRCUIT CURRENT (ISC) MAX SERIES FUSE (OCPD) MAXIMUM POWER (PMAX) MAX VOLTAGE (TYP 600VDC) VOC TEMP COEFF (mV/oC or %/oC ) IF COEFF SUPPLIED, CIRCLE UNITS A V V A A W V MODULE MAKE MODULE MODEL PV MODULE RATINGS @ STC (Guide Section 5) MAX DC VOLT RATING MAX POWER @ 40oC NOMINAL AC VOLTAGE MAX AC CURRENT MAX OCPD RATING V W V A A INVERTER MAKE INVERTER MODEL INVERTER RATINGS (Guide Section 4) 1) IF UTILITY REQUIRES A VISIBLE-BREAK SWITCH, DOES THIS SWITCH MEET THE REQUIREMENT?
