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. 509 S Starboard St 10/31/22 Expedited Permit Process for PV Systems2 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)_________________ ft 2 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. 509 S Starboard St 10/31/22 Ex 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                                                          NGUYEN ING ELECTRIC 509 S.

FEATURES 25 years 10 years -0/+5% 1000 volts 100% lead-free solder Linear performance warranty Workmanship & materials warranty Positive power tolerance Maximum system voltage Safer for the environment Half-cut, four bus bar, monocrystalline cells increase module efficiency Four-layer protective junction box reduces risk of failure from water or dust intrusion, enhancing reliability and safety Proprietary cell surface texturing process increases light absorption Beveled frame edge and drainage notches Double anodized frame for greater corrosion resistance Solid C-Channel frame The Diamond Premium 280W is a high-efficiency module with half-cut, four busbar monocrystalline cells. Designed for durability with a double coated anodized frame and I-beam support bar, the Diamond Premium excels in any environment. Technological Innovations Enhanced Reliability Mitsubishi Electric Quality Engineering excellence and attention to the finest detail ensure longevity and optimal performance. Our corrosion-resistant design even allows installation in coastal areas. Our experienced engineers and meticulous manufacturing processes provide the highest quality products possible. Automated production lines ensure consistent high quality in every cell and module, each flash tested to ensure rated level of output. All Mitsubishi Electric modules are manufactured in Japan and made with 100% lead-free solder, a safer and more eco-friendly solution. Modules are the heart of a PV system. Why take chances? Mitsubishi Electric, a diversified global Fortune 500 firm founded in 1921, manufactures panels that greatly exceed industry requirements. With 40+ years of PV experience, Mitsubishi has small and large installations around the globe, demonstrating the strength and resilience of the modules in a variety of environments. Mitsubishi modules, designed for reliability and durability, are manufactured in our own factories in Japan. With financial strength and unparalleled product quality, you can count on Mitsubishi Electric. The Diamond Premium series of panels features several innovations, including half-cut, four busbar cells, improving efficiency and reducing the potential for micro cracking. Drainage notches also keep panels cleaner and producing more electricity. Thicker frames and an I-beam support bar bolster frame rigidity to protect the cells. The four-layer, potted junction box enhances safety by keeping dust and water out. 97.7%Excellent low light performance Accelerated aging test 2000 hours damp heat test 400 thermal cycles 2000 hours D E C ø 0 . 1 6 ( ø 4 . 0 9 ) ( 4 P L A C E S ) ø 0 . 3 5 ( ø 9 ) ( 4 P L A C E S ) 39 . 4 ( 1 0 0 0 ) 47 . 2 ( 1 2 0 0 ) 64 . 0 ( 1 6 2 5 ) 45 . 9 ( 1 1 6 7 ) B B A A 40.1 (1019) 1.81(46) 38.4 (976) A Grounding Mark Drainage Holes C B Grounding Mark 1. 0 0 ( 2 5 . 3 ) D E Drawings and Dimensions Unit: inch (mm) Electrical Characteristics Printed on recycled paper.

Seismic Load: Per the CEBC 2019 Section 503.4, if the demand-capacity ratio of the lateral load-carrying elements increases less than 10% due to the addition of the solar system, no special provisions or structural modifications are required. Existing Roof Weight = 14.0 psf * 2490 sf = 34860 lbs Weight of Solar System = 21 modules * 41.4 lbs + 189 lbs of racking = 1058 lbs 1058 lbs / 34860 lbs = 0.03 The increase in load from the solar system will not increase the demand-capacity ratio of the existing lateral load-carrying elements by over 10%.
