incident angle value in hourly data for tracker

[sudeeptiwari84]

Hi,

as we do simulation for tracker system and get calculations of incident angle in hourly data, so that value of incident angle is avg. value of that hour or is it the instantaneous value at that time .

please clarify.

The PVsyst simulation works in hourly values, i.e. on hourly averages of Irradiance and other variables.

The solar geometry is computed in the middle of the hour, for an application on this average.
