A new application must be submitted for the addition as an “aspect of an existing facility.” This is available in Step 1 of the application. 

If the new system is metered with the original system, please provide information for only the additional equipment installed. This includes the additional array(s) details such as the number of modules, orientation, and module power rating as well as additional (not preexisting) inverter(s) installed. You will also need to provide the existing PA Certification Number and a new Certificate of Completion/Permission to Operate issued by the utility if there are changes to the AC size. 

If the new system is separately metered, please provide proof that production is recorded and monitored separately (a screenshot of the monitoring portal or photo(s) of the solar dedicated meters will suffice). Separately metered applications will require all new supporting documentation. Please include “(second system)” or “(addition)” after the street name to avoid a duplicate address error..
