Information for residential solar electric contractors

The following information will help you better serve your residential customers with their solar electric project. The major steps that you need to take to safely interconnect your customers' solar systems to SRP's electric grid are outlined below. SRP does not limit the size of a residential customer's solar system.

SRP has moved to an online platform and can no longer accept Distributed Energy Resource applications via email. Effective Saturday, May 1, 2021, all applications must be submitted via PowerClerk.

Step 1 - Review program requirements

To ensure that your customer's home meets the criteria for a solar electric system, before starting the application process, please see the following:

Step 2 - Technical interconnection requirements

It is important to understand and comply with SRP's interconnection requirements to ensure the solar electric system is safely interconnected with the electrical grid. The technical resources below will help you understand SRP's requirements.

Step 3 - Application submittal

Contractors must submit a complete application package to SRP on behalf of their customer prior to system installation in order to ensure the system configuration is approved by SRP. The application must be submitted via PowerClerk.

SRP will review the application package for completeness. If additional information is needed, SRP will notify the installer and customer. If everything is in order, an email will be sent notifying them that the project has been approved.

If changes to any portion of the application package are made after the approval, the customer or their contractor must submit a change request form in PowerClerk and upload copies of all applicable documents that must be revised as a result of the changes. Please note that the application may move back in the process depending on the changes, resulting in a lengthier application processing time.

Step 4 - Additional documents

Once your application is approved, an Interconnection Agreement Document is a PDF will be sent to the property owner via DocuSign.

Step 5 - Design review

SRP will create an order on the Customer's account to track the design review phase of the process. After the order is created, the project will be assigned to an SRP design consultant who will check the proposed electrical design to ensure it meets SRP's interconnection requirements. The Customer and Installer will be notified if there are any issues or if any additional information is needed.

  • If a de-rate is required, you will be required to use the Meter Pull form in PowerClerk to schedule the appointment.
  • If your project is in a jurisdiction that does not issue permits for electrical work associated with the installation of a solar system, you must submit a Certificate In-lieu of Electrical Clearance (CILC) Document is a PDF to CCDesk@srpnet.com in advance of scheduling an appointment date. Both the customer and contractor must sign the CILC.
  • If you are upgrading or performing maintenance on the Service Entrance Section (SES) you must contact SRP Construction at 602-236-0777 to schedule the appointment.
  • If the application covers modifications to a commissioned DER system, three-line electrical diagram and site plan must include as-builts from existing system.

Note: Design must be approved before SRP will accept City Clearance or a Certificate In-lieu of Clearance documents.

Step 6 - Installation

Upon receiving SRP design approval to proceed and obtaining all applicable building permits as required by the authority having jurisdiction (AHJ), the contractor can then install the equipment according to the specifications approved by SRP and the AHJ.

Step 7 - AHJ inspection

After installation, the contractor will need to request an inspection from the AHJ. The AHJ is responsible for submitting their system clearance to SRP. SRP will not accept clearance notification from any entity other than the AHJ.

If the applicable AHJ does not require building permits or inspections, the contractor must submit an SRP Certificate In-Lieu of Electrical Clearance for Distributed Energy Resource Interconnection Projects Document is a PDF to CCDesk@srpnet.com. Both the customer and the contractor must sign the CILC.

Step 8 - SRP final inspection and commissioning

Once the DER system has received CC/CILC and SRP has received the IA signed by the Customer, an email from no-reply@sharepointonline.com will be sent to the Installer with a link to the SRP Contractor website. Download Inspection Checklist Document is a PDF

  • Installer will see all pending inspections.
  • Installer will schedule the customer's final inspection/commissioning appointment. (If any revisions need to be made to site plan or three-line documents, the revised documents must be received by SRP at least 5 business days before inspection/commissioning appointment.)
  • Installer will receive email notification that Customer has been scheduled.
  • It is Installer's duty to inform Customer of the scheduled appointment.
  • If the system fails inspection, an email will be sent to Installer with a description of the reasons for the failure.

Step 9 - Permission to operate and rebate incentive checks

  • Upon successful completion of the final inspection and commissioning, the DER Facility may be energized.
  • After commissioning, if application included a qualifying demand management system, a rebate check will be processed by SRP and mailed to customer. Allow us up to six weeks for check processing.
  • A "permission to operate" letter will be sent to installer after commissioning.
