Advancing Clean Energy, One Permit at a Time

SolarAPP+ is the only permitting platform that was developed in full collaboration with its stakeholders to both support the entirety of an industry and the environment in which it operates. Funded by the Department of Energy (DOE) and initially managed by the National Laboratory of the Rockies (formerly NREL), SolarAPP+ was developed in collaboration with local building officials and inspectors, standards development organizations, and solar installers.
