The photovoltaic (PV) slope is the angle at which the panels are mounted relative to horizontal. A slope of 0° corresponds to horizontal, and 90° corresponds to vertical. With fixed-slope systems, a slope roughly equal to the latitude typically maximizes the annual PV energy production. The azimuth specifies the direction towards which the panels slope.
If you choose a horizontal-axis or two-axis tracking system, HOMER does not let you enter the slope, but rather calculates it in each time step.
