Estimates the energy production of grid-connected photovoltaic (PV) energy systems throughout the world. It allows to easily develop estimates of the performance of potential PV installations.
Description
NREL's PVWatts® is a web application developed by the National Renewable Energy Laboratory (NREL) that estimates the electricity production of a grid-connected roof- or ground-mounted photovoltaic system based on a few simple inputs. To use the calculator, you provide information about the system's location, and basic design parameters. PVWatts® calculates estimates of the system's annual and monthly electricity production.
Important Note. PVWatts® is suitable for very preliminary studies of a photovoltaic system that uses modules (panels) with crystalline silicon or thin film photovoltaic cells. PVWatts® production estimates do not account for many factors that are important in the design of a photovoltaic system.
