[TRNSYS-users] Visual Fortran run-time error

[Jeff Thornton via TRNSYS-users]

The three slope inputs must be set to the same value.  Slope is defined as 0 degrees = horizontal and 90 degrees = vertical facing the provided surface azimuth.  Click on the "more" buttons in the proformas, I'm pretty sure that the slope is defined in each of the models but may be wrong.

But, I couldn’t see any significant variation of output of solar PV panels. It has not defined this parameter or sign convention for that on help manual
