What is SolarAPP+

It's an automated online application for instantaneous permitting of new residential rooftop solar and storage systems.

Why use SolarAPP+

• Obtain a permit without needing a full plan diagram
• Lower your costs, including three free revisions
• Expedites installation with instantaneous permit issuance once you've completed the application
• Adding ESS (Battery Energy Storage Systems) are now eligible thru Solar APP+ (NEW 1/2026)

As a result, SolarAPP+ lowers costs and expedites solar installations, encouraging property owners to invest in generating renewable and sustainable energy.  To see which systems are eligible, please refer to the Eligibility Checklist.  Only projects that conform to this list are eligible to use the automated SolarAPP+ portal for instant permitting.  All other Solar/PV installations require a regular Building Permit.

How to get started:

• If you are a licensed contractor or installer, you may register for a new SolarAPP+ account (Non-licensed/owner-builders must apply for a regular Building Permit with Plan Check.)

• After registering with SolarAPP+, it's as simple as:
  • Apply for pre-approval on the SolarAPP+ website.
  • Go to the City of El Cajon Solar APP+ online permit site and apply for a permit.  
    • Note: You will need to log into your online account at the Project Assistance Center Online (PACO) or register for an account if you do not have one.
  • Follow the on-screen instructions to fill out the application, making sure to enter the SolarAPP+ re-approval ID number you were issued by SolarAPP+ and upload all required documentation.
  •  Once you've paid all applicable fees your permit will be immediately issued electronically.

• Please complete the third party inspection declaration on the permit and upload to PACO using the "ATTACHMENTS" tab, and request a Final Review in order to obtain a release of solar to SDG&E.  No other City inspections will be required.
