Improvements to PVWatts for Fixed and One-Axis Tracking Systems

Research output: NRELPoster

Abstract

This work presents improvements to the widely used NREL PVWatts photovoltaic system energy model to improve modeling accuracy for typical fixed and one axis system designs. These improvements allow users to more credibly and quickly evaluate competing system designs in early stage feasibility, and are shown to improve PVWatts' system performance prediction capabilities without major impact to ease of use.
