Hi,

There may be locations where this occurs, look at sunrise and sunset times for your location and be aware of the time of year you are looking at results for. If using SunCast you can review the results here before proceeding to simulation.

In short as long as you have correctly specified location and are using a valid weather file then there is no way this would be calculated wrongly.
