PVWatts Calculator

Interactive web application that allows homeowners, installers and manufacturers to easily develop estimates of the performance of potential PV installations at specific locations. The calculator estimates the electricity production and energy value of a grid-connected roof- or ground-mounted photovoltaic system based on default inputs or user-defined inputs about the system's location, basic design parameters, and system economics.
