Please review this checklist and make sure you have all of the necessary information before plan submittal. If you have any questions regarding plan submittal or this checklist you may contact the building division


All information must be submitted online


  • Site Plan: A detailed site plan showing the location of the home and all PV system components on the property. Show all fire code clearance requirements.

  • Mounting System: Provide detailed information on the module mounting system and also the weight of all components on the roof.  Note if the home roof rafters are engineered trusses. Also note the type of roofing coverings (shingles, metal or tile) and how many layers of covering there are. Provide engineering for loads on roof as well as uplift.

  • One-line diagram: A detailed one-line diagram is required and must show the types of PV system being installed (a single inverter system with one or more strings of modules connected in series, a micro inverter system or an AC module system), the exact number and layout of modules and how they are connected together (in series or in parallel), all wires types, all wire sizes, conduit types and sizes, detailed info on the grounding wiring and connections, the location of circuits and system components on or in the house, and the ratings of all fuses or breakers.

  • Electric panel to be back fed: Note which home electrical panel the PV system will back feed and give the location and rating of that panel. Please provide a picture of the panel that is going to be back fed with a picture of its interior label. Note: Code violations in existing panels will need to be corrected.

  • Module spec sheets: Provide the PV module (solar panels) spec sheets showing the modules’ STC rate watts (Pmp), volts (Vmp), amps (lmp), open circuit voltage (Voc) and short circuit current (Isc). Modules must be listed UL 1703.

  • Inverter spec sheets: Provide the inverter manufacture spec sheets showing the amount of watts and volts the inverter can safely handle and also noting what the inverters max rated AC output amps and voltage is. Utility tied inverters must be listed as “utility interactive” meeting UL 1741 and have ground fault protection.

  • Total array power: Provide the total amount of watts, amps, volts, open circuit voltage (Voc at the coldest possible outside temperatures: see NEC 690.7) and short circuit current that the array can produce (this is not required for systems with microinverters).

      System components: Provide information on the different types of components that will be used in the system and how they are         to be installed. Also, show that all equipment is listed and rated for the types of voltage (AC or DC), amount of voltage and the               amount of current that it could be subjected to.

  • System labels and markings: Provide warning label information for the entire system to be installed (See NEC 690).

  • Bonding: Provide bonding information and specifications for system components.

  • Rapid Shutdown: Provide information and equipment listing (see NEC 690.12)


This checklist is only a basic list of items needed to begin a Solar PV system plan review and is not all-inclusive. Having all the items listed on this checklist does not guarantee a permit will be issued and any additional plans, information and or requirements may be requested or required by Fairfield Town at any time.
