* Alternate Energy Inc’s energy production estimates use the National Renewable Energy Laboratory’s (NREL) PVWattsTM calculator. It determines the energy production and cost savings of grid-connected photovoltaic (PV) energy systems throughout the world. It allows homeowners, installers, manufacturers, and researchers to easily develop estimates of the performance of hypothetical PV installations. The PVWatts calculator was developed by NREL’s Electricity, Resources, and Building Systems Integration Center.
