Is there a limit on system size SolarAPP+ can review?

SolarAPP+ is for rooftop residential solar systems. While SolarAPP+ does not specify a limit for the system’s total rated wattage capacity, there are technical limits on the power rating of service panel equipment, and these are enforced by SolarAPP+.  Projects may be permitted to interconnect to a maximum main service rating of 400A, and service disconnects and busbars rated for a maximum of 225A. Within these parameters, SolarAPP+ can approve systems up to 38.4 kW provided they meet certain installation characteristics. If any project components exceed the above specification thresholds, the project will be designated as ineligible by the SolarAPP+ platform. See the Eligibility Checklist for more information.
