Permit Process for PV Systems

CMR Solar Energy Integrators follows an U.S. standard report which has been created to meet the needs of the growing, small-scale photovoltaic (PV) market in the U.S. and is applicable nationwide.

It takes advantage of the many common characteristics inherent in most of the small-scale PV systems installed today to streamline both the application and award of permits.

Local jurisdictions are responsible for establishing the permitting requirements for new PV system construction and installation in their territory.

The majority of residential-sized PV systems installed in the United States share many similarities of design. It is the similarity and commonality of these designs that would allow for a nationally standardized expedited permit process for small-scale PV systems.


Recommendations to our Costumers

CMR Solar Energy Integrators permits are base using the nationally standardized Expedited Permit Process. Jurisdictions can be assured that they are consistent in their application of codes and standards. We assured that the requirements for permitting will not vary dramatically among jurisdictions. Both of these assurances result in safe, cost effective installations and accelerate PV technology use. The primary need and use for this process is for systems of less than 15kW maximum power output. The expedited permit process is intended to simplify the structural and electrical review of a small PV system project and minimize the need for detailed engineering studies and unnecessary delays. The majority of PV systems installed in the U.S. meet the elegibility requirements outlined in this process and will benefit from the ease of using a one-page expedited permit form.


Services Offered: Permit Status Review

CMR Solar Energy Integrators will identify key permit and schedule milestones, and Evaluate on-going status of permits including:

  • Building permits, easements, grading, dust, etc.
  • Incentive reservations and proof of progress
  • Utility interconnection/net metering/ FERC/ISO
  • Environmental permits

Expedited Permit Process for PV Systems

The Solar America Board for Codes and Standards (Solar ABCs) Expedited Permit Process 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 Solar ABCs recommends that jurisdictions adopt and use this permit process.

In jurisdictions that have adopted the Expedited Permit Process for PV Systems, the interactive pdf forms contained in this file may be used for preparing permit applications. Guidelines with a full explanation of how to use these forms are available online at www.solarabcs.org/permitting. Tables and diagrams can be filled out electronically and submitted either in printed form or via email to local jurisdictions which accept this form. The electronic format that is used promotes standardization and legibility for the local jurisdiction.

Solar America Board for Codes and Standards

The Solar America Board for Codes and Standards (Solar ABCs) is a collaborative effort among experts to formally gather and prioritize input from the broad spectrum of solar photovoltaic stakeholders including policy makers, manufacturers, system designers, suppliers, installers, electric utilities, and consumers, resulting in coordinated recommendations to codes and standards making bodies for existing and new solar technologies. The U.S. Department of Energy funds Solar ABCs as part of its commitment to facilitate widespread adoption of safe, reliable, and cost-effective solar technologies.

Expedited Permit Process for PV Systems

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
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, and 15 kWSTC or less.
  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. The electrical diagram (E1.1) can be used to accurately represent the PV system.
