The easiest way to do it is to print every hour and then use a spreadsheet program like Microsoft Excel to filter out the times where there is no solar radiation. If you only want "integrated" values of outputs during daylight periods you can use equations and then integrate the equations. For example, the useful collected energy from type 1 during daylight hours: Equations 2 I_Daylight=GT([16,7],0) !Sets the value to one if beam radiation is greater than 0. Qu_Daylight=I_daylight*[1,3] Then you simply integrate Qu_daylight and not 1,3.
