NREL have provided the public with another useful tool: The PVWattsTM calculator. It allows users to substitute its default input parameters with custom values. Learn how to change the PVWatts parameters for: DC rating, DC-to-AC derate factor, Array type, Tilt angle, Azimuth angle, Electricity cost. It also provide graphs that show energy derating as function of ground cover on a PV farm. array.
