The document outlines a training program on rooftop solar PV for utility engineers presented by USAID's Partnership To Advance Clean Energy-Deployment technical assistance program. It includes a quiz to test knowledge on topics like solar applications, system components, site assessment factors, and state targets for rooftop solar. The training aims to increase understanding of grid-connected rooftop solar PV systems.
