Karnataka is the most power deficit state in the Southern regional grid. The average and peak deficit has been higher than the national average for the last five years. Chronic power deficits resultin load shedding leading to not only inconveniences, but also economic losses (Bose et al, 2006). One of the solutions to address power deficits is to utilize vacant rooftops and install solar panels. Institutions like schools, colleges, universities, and offices are suited specifically for this purpose as these have their major electricity requirement during the day when the sun is available (8am to 6pm). Rooftop solar power can meet a substantial portion of institutional electricity demand on working days; also it can be exported to the grid during weekends and holidays, when the institutes’ activities are minimal.
