Hello, Hope someone can help me with defining the azimut and tilt angle in the design part of PVsyst. We develop projects in the southern hemisphere so theoreticaly we should aim our solar modules to the North. Should I insert a value of 180° of azimut in the "orientation" sheet? or the software automatically re-defines the azimut axis when I define a project location (In the southern hemisphere) in the "project" sheet and therefore I should let the azimut value in 0°. I'm using version 5.74. Also, i think the azimut that is showed in the far horizont obstacles part, he one in the transposition chart tool and the one defined in the gobal tilted plane radiation tables are contrary, what I'm not seeing? Kind Regards, Miguel

Good afternoon,´ My consult is about how to interpret the suggested capacity of the battery given by the PVsyst at the top-right corner of the components selection window. My Suggested battery capacity is 2000 A-h. I know that the database of the batteries in the software rate the capacity at C10 , however, i got a calculation from another software made by a distributor of battery banks resulting of an equal value but telling me that the value is at C100 because the calculation for the battery uses an amount of energy that will be used by 7 days ( my autonomy is seven days) and that amount of hours is something like 168 h, therefore i had to buy a battery of 2000A-h at C100 because 100 hours is "closer" to 168 hours. kind regards, Miguel Guevara
