The following table provides the weather-corrected insolation in Wh/m
2
every 15 minutes for
every day of the year for the specific panel tilt and azimuth specified for the skyline. For the
NASA weather model, weather corrections are based on historical average monthly clearness
indexes from NASA. For the NREL – TMY3 weather model, corrections are based on the
hourly NREL data for the weather station specified in the session.
• This data is in standard time and does not include adjustments for daylight savings.
• These values are not affected by shading (that is, they assume no shading).
An example of the header and part of the data is shown below:
