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. 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.
