SolarAPP+, short for Solar Automated Permit Processing Plus, is an online web portal that automates the plan review and process for issuing permits to qualified businesses or individuals to install code-compliant residential photovoltaic (PV) systems. Based on model building, electrical, and fire codes, SolarAPP+ automatically performs a compliance check based on inputs supplied by the contractor to ensure the proposed system is safe and code compliant. Installation practices, workmanship, and adherence to the approved design are then verified by the local code official through the inspection process.
