-
Tilt and Orientation Factor (TOF). TOF is the solar insolation at
the actual tilt and orientation divided by the insolation at the optimum
tilt and orientation, expressed in percent.
-
Total Solar Resource Fraction (TSRF). TSRF is the ratio of
insolation available accounting for both shading and TOF, compared to the
total insolation available at a given location at the optimum tilt and
orientation and with no shading. TRSF is also expressed in percent,
according to the following equation: TSRF = Solar Access * TOF.
