Annual Insolation vs. Panel Orientation
for over 1,000 locations in The United States
The National Renewable Energy Laboratory (NREL) recently published new weather data for over 1,000 locations in the U.S. called TMY3 data, for “Typical Meteorological Year 3”. Using this data, Solmetric has calculated insolation values in kWh/m2 for a range of fixed tilt and azimuth values and produced a color grade chart for each of these NREL locations. The example chart below highlights the main elements of the plot.
