Solar Permitting

In order to identify if a PV system or PV+ESS installation is simple, needing only a basic review, the following information is required.

1. Obtain the Local Government’s Permit Application

– Permit application should include information about the project scope, project location, and the installer.

2. Develop the Site Plan 

– Site plan should show location of major components on the property. The site plan drawing need not be exactly to scale, but it should represent relative location of components at site (see supplied example site plan).

– PV arrays in compliance with IRC fire setback requirements need no separate fire setback requirements. Energy storage in acceptable locations.

3. Obtain Electrical Worksheets

– Electrical worksheets should show: PV array configuration; wiring system; overcurrent protection; ESS components; inverter; disconnects; required signs; AC connection to building. See supplied standard electrical diagrams:

• Example Diagram 1: One-Line PV Only with Microinverters
• Example Diagram 2: One-Line PV Only with DC Converters
• Example Diagram 3: Site Diagram PV Only with DC Converters
• Example Diagram 4: One-Line PV and ESS with Microinverters and MID
• Example Diagram 5: Notes for One-Line PV and ESS with Microinverters and MID
• Example Diagram 6: One-Line PV and ESS with String Inverters and MID
• Example Diagram 7: One-Line PV and ESS with String Inverter and MID with Service Disconnect
• Example Diagram 8: One-Line PV and ESS with String Inverter with DC Converters and MID
• Example Diagram 9: Notes for One-Line PV and ESS with String Inverter with DC Converters and MID
• Example Diagram 10: One-Line PV and ESS with Multi-mode Inverter

  

4. Obtain Specification Sheets & Installation Manuals (if available)

– For all major PV system and ESS components such as:

• PV Module – Installation Manual (e.g.)
• DC Converter – Installation Manuel (e.g.)
• ESS Components – Installation Manual (e.g)
• Inverter – Installation Manual (e.g.)
• Mounting System – Installation Manual (e.g.)
