Contractors: Installing Solar PV Panels

Effective July 1, 2025, all customers who submit a completed solar interconnection application will be credited for energy exported to the grid at the community solar farm rate for a five-year period ending June 30, 2030, and at the retail fuel rate thereafter.

If an OUC customer has contracted your services for the installation of solar PV panels, please follow the steps below to ensure successful installation and interconnection:

1. Email OUC: Send the service address and proposed size system or one-line diagram to Green@ouc.com for review of a transformer upgrade.
2. Obtain Permits: Pull all necessary permits from the appropriate jurisdiction.
3. Install the Solar System: All PV system installation must comply with OUC's Interconnection Requirements.
4. Permit Inspection: Complete final permit inspection with designated jurisdiction.
5. Submit Interconnection Application: After permit inspection is complete, help the customer by submitting an online interconnection application. Please see below for a list of required documentation.

Submitting an Interconnection Application
All interconnection applications and supporting documentation must be submitted via our online portal. For registration instructions, click here. Once registered, contractors will be able to submit their customers’ interconnection applications via the portal, as well as track application status.

Required Documentation
Make sure the following documents are submitted as part of the interconnection application.

1. Passed City/County Permit Inspection or Certificate of Completion.
2. Proof of purchase of the solar system. Invoice requires customers name, service address, itemized cost, and customers signature. Reflect the cost of the battery separate from the Solar PV system, if applicable.
3. An electrical one-line diagram. Must be stamped and signed by a professional engineer to include the KW DC size and service address. Click here to view an example of an acceptable one-line diagram.
4. Proof of insurance (if applicable)
5. Payment (if applicable)

OUC will review the application and if approved, will reconfigure the meter. In rare cases, the customer's existing electric meter may be exchanged for a bi-directional meter.
