Solar Permits

 

A. Determining Historic Significance

State law protects historic or potentially historic structures from additions or alterations that may affect the historic character of the structure. Structures designated as historic or eligible to be designated historic with proposed roof-top solar energy Historic Homesystems need to adhere to The Secretary of the Interior’s Standards for Rehabilitation; “Incorporating Solar Panels in a Rehabilitation Project”.  Therefore, prior to applying for a roof-top solar energy permit, find out if the structure is a designated or eligible historic resource by clicking here and entering either the assessor's parcel number (APN) or address.

  • If the structure is "designated" or "eligible for designation," follow the instructions to obtain Historic Eligibility Clearance before applying for your proposed solar permit. 
  • If the structure is not a designated or eligible historic resource, return to this webpage and follow the guide below.

B. Photovoltaic Submittal Requirements

The "Streamline Photovoltaic" Permit process is available for residential solar photovoltaic (PV) projects up to 10 kW.  All other projects follow "Standard Photovoltaic" permitting procedures.  Follow the guides below for information about submittal requirements and forms, where to submit plans, required fees and inspections.

1.  Requirements for Streamline Solar Photovoltaic Permitting

Eligibility Requirements

To qualify for this program, the solar PV project must be located on a residential rooftop, have a maximum power output of 10kW and the following must be completed and submitted:

  

 

Central/String Inverter System Micro Inverter System

 

 

2.  Requirements for Standard Solar Photovoltaic Permitting

a. Submittal Requirements

C. Where to Submit

Permit applications may be submitted to the Development Services Department in-person or online via Citizen Access:

  • In-person submittals may be made at the Development Services Permit Counter, located at 276 Fourth Avenue (Building B), Chula Vista, CA  91910
  • Online submittals may be made through Citizen Access, the City of Chula Vista's online permitting service.  Online permits are available to registered licensed contractors

D. Fees

  • Residential rooftop PV system: $250
  • Electrical panel upgrade (if required):         
    • $111 if included with the PV permit
    • $234.75 if a separate permit (Minor Electrical permit)
  • May be paid online or in-person

 

E. Inspections

Once all permits to construct the solar installation have been issued and the system has been installed, the system must be inspected before final approval is granted for the solar system. Permit holders must be prepared to show conformance with all technical requirements in the field at the time of inspection. The inspector will verify that the installation is in substantial conformance with applicable code requirements and with the approved plans.  The approved plans shall be made available on site to the inspector at time of inspection.  In addition, completed Circuit Card and, if applicable, SDG&E Work Order, shall be made available on site at time of inspection.

 

General Inspection Checklist:

      Number of PV modules and model number match plans
      Specification sheets number matches plans and specification sheets
      Array conductors and components are installed neatly
      PV array is properly grounded
      Electrical boxes are accessible and connections are suitable for environment
      Array is fastened and sealed according to attachment detail
      Conductors’ ratings and sizes match plans

 

Signage Checklist:

      Sign identifying PV power source system attributes at DC disconnect
      Sign identifying AC point of connection
      Sign identifying switch for alternative power system
      Plaque identifying the location of all customer self-generation equipment, the service point, the DC disconnect(s), and the AC disconnect for Utility Operation must be installed on the service equipment. Link to sample plaque
      OCPD connected to the AC output of the inverter is rated at least 125% of maximum current on sign and is no larger than the maximum OCPD on the inverter listing label.
      Array is fastened and sealed according to attachment detail
      Conductors’ ratings and sizes match plans

 

Equipment Rating Checklist:

      Inverter has a rating as high as max voltage on PV power source sign
      DC-side overcurrent circuit protection devices (OCPDs) are DC rated at least as high as max voltage on sign
      Switches and OCPDs are installed according to the manufacturer’s specifications (i.e., many 600VDC switches require passing through the switch poles twice in a specific way).
      Inverter is rated for the site AC voltage supplied and shown on the AC point of connection sign.
      Sum of the main OCPD and the inverter OCPD is rated for not more than 120% of the bus bar rating.
