SolarAPP+ Applications are Now Open

The Illinois Finance Authority, in its role as Illinois’ Climate Bank, is pleased to release a Notice of Funding Opportunity to support units of government that would like to adopt SolarAPP+ residential solar permitting software. The program will give up to 10 grants of up to $30,000 each to Illinois municipalities to fund staff time and expenses necessary to implement SolarApp+. The grants may also be used to update residential electrical codes, where that effort is necessary to adopt and implement SolarApp+.

SolarApp+ is a no-cost permitting software developed by National Renewable Energy Laboratory (NREL) to streamline permitting processes for standardized solar systems. SolarAPP+ automates rooftop solar plan reviews and produces instant compliance approvals for municipal governments. The software addresses plan and building code compliance and does not address utility interconnection reviews.
