Solar Calculators


The PV Watts Version 1 Calculator calculator allows users to select a photovoltaic (PV) system location from a list of options. The National Renewable Energy Laboratory developed PVWATTS to permit non-experts to quickly obtain performance estimates for grid-connected PV systems.    http://rredc.nrel.gov/solar/calculators/PVWATTS/version1/

 
This Solar & Wind Estimator will estimate the size and calculate the cost to install an energy system for your home or building. Technology options include solar electric (PV), solar water heating, pool or spa heating, space heating & cooling, and wind turbines.  http://estimator.solar-estimate.org/index.php
