PVWatts® Calculator

A tool is available through the National Renewable Energy Laboratory (NREL) that estimates the energy production and cost of energy of grid-connected photovoltaic (PV) energy systems. The tool, PVWatts^®, is a free application that allows consumers to easily develop estimates of the performance of potential PV installations. NREL is a third-party research laboratory of the U.S. Department of Energy and the Office of Energy Efficiency and Renewable Energy and is not associated with Northern Neck Electric Co-op.
