More on Each Step

Follow the 4 steps below to properly install and receive approval for a commercial PV system in Palo Alto.

a. Design Considerations

For PV permits approved after 9/8/17, Smart Inverters are required as described in CPAU's Rule 27.

b. Fire Marshal Guidelines

The City of Palo Alto has adopted the state of California's Fire Marshal Guidelines. Review the CA State Fire Marshal PV Installation Guidelines to ensure the plans for your commercial PV system comply.

If your plans do not comply, you must submit an email request for a variance from the California Fire Code setbacks, as follow:

EMAIL: To: fire@cityofpaloalto.org, CC: james.henrikson@cityofpaloalto.org
SUBJECT LINE: "Fire PV Variance Request for <street address>
CONTENT: Include attachments for all appropriate drawings and schematics relating to your plans


c. Planning Entitlement Guidelines


Consult with the City's Planning Department to determine if a separate planning entitlement application is required in advance of a building permit based on the scope of your project.  This is typically required for ground mounted systems or solar awnings where new structures, such as parking lot carports, are constructed to support the new solar installation. 

a. Prepare Submittal Package

Use the Commercial PV Submittal Checklist to guide you through the permit submission requirements to prepare your application for a PV Permit.

b. Prepare Electric Load Sheet

You must fill out all appropriate sections of the PV Electric Load Sheet and Interconnection Agreement and submit with the Commercial PV permit application.


c. Customer Signs Net Energy Metering Interconnection Agreement (NEMIA)


The owner of the solar installation must sign a completed Net Energy Metering Interconnection Agreement (NEMIA) and the signed NEMIA must be turned in as part of the submittal package in order for a PV Permit to be issued. 

d. Submit Application In Person

Commercial PV permits are to be submitted in-person to the City of Palo Alto Development Center during normal business hours.

e. Permit Approval

If your submission is approved, you may receive your permit within several business days.
