While solar photovoltaic (PV) technology has become a new attraction to the home owners and institutional rooftop owners, It has become important for estimating the rooftop PV potential for planning a solar project. Infact this will also help the Discoms to accommodate the rooftop solar PV in their distribution system. Recently TERI has been engaged by Shakti Sustainable foundation for a similar work to estimate the potential through a web based rooftop solar potential estimation through GIS. THe proposed rooftop web based GIS tool for India is ideal for planning their investments in rooftop solar energy investments. While currently this exercise is for a few cities, the same is to be done at national level to help investors to plan their investments in rooftop solar PV investments.
NREL has also developed a similar tool known as In My Backyard (IMBY) tool which estimates the electricity you can produce with a solar photovoltaic (PV) array at your home or business. Homeowners, businesses. Based on your location, system size, and other variables, IMBY estimates the electricity production you can expect from your system.
