U.S. Department of Energy NREL program’s In My Backyard (IMBY) Calculator
This tool allows homeowners, businesses and researchers to estimate the amount of electricity they can produce using a solar photovoltaic (PV) system or a wind turbine.
NREL’s PVWatts Site Specific Data Calculator
This tool uses hourly typical meteorological year (TMY) weather data and a PV performance model to estimate annual energy production and cost savings for a crystalline silicon PV system.
