The file I built and shared last year fails in the new version of SAM: exec fail(pvsamv1): subhourly weather files must specify the minute for each record Simulation pvsamv1 failed. Do I need to do something extra or different because the minute for each record is show?
SAM requires that a weather file for sub-hourly simulations include a minute column indicating the minute it should use for sun angle calculations. You should modify your SAM CSV weather file by adding that column.
