Automated Permit Processing for Solar (APPS) Grant

Submitted by [user:field_first_name]

The Automated Permit Processing for Solar (APPS) program is a non-competitive grant program offering financial assistance to local and Tribal governments to implement automated online solar permitting software, such as SolarAPP+ or Symbium. This type of software instantly verifies the code compliance of solar systems and issues permits, which saves staff processing time, enables solar businesses to install systems more efficiently, and ensures Coloradans who have invested in rooftop solar panels can start benefiting from them as quickly as possible.
