When you use the TiltAzimuth option, the irradiance calculation is detached from your model geometry. It assumes shade-free PV modules with the tilt and azimuth you specify. If you use the Surface option, the irradiance on the specified surface is used, shading included. The capacity is determined by the DC System Capacity input parameter, therefore the area of the array is not needed.
See I/O reference on page 2239.
