Counter Reviews for Residential Solar Photovoltaic Systems




Choose one of the 11”x17” single line configurations for your PV design: J-Box to Inverter; J-Box to Combiner Box to Inverter; or, J-Box to Combiner Box to DC Disconnect to Inverter; or Microinverter Single String. Download and provide the information requested in each component, wiring and/or grounding box. Please be sure to download and include the Signs and Labeling for Single Inverters or Signs and Labeling for Microinverters and Storm Water Pollution Prevention Notes in each set of drawings.

Assemble three sets of plans according to the drawing format below. Complete the City of Irvine’s Building Permit Application and Residential Take-Off Sheet.

 If the design is not in compliance with Planning and/or Building codes and ordinances, plan review comments will be created for you to respond to and/or revise your plans accordingly and resubmit the project for further review. Please submit three revised sets and the original sets for comparison.
