This presentation will include a demonstration of the National Renewable Energy Laboratory's (NREL) free online PVWatts tool for estimating the production of a photovoltaic system with a discussion of the solar resource data it uses from the National Solar Radiation Database (NSRDB) and how it fits in with other free NREL tools for analyzing photovoltaic systems and projects. This presentation is for people who want to learn about PVWatts capabilities and limitations who have a basic understanding of how photovoltaic systems work.
