As it is observed in Figure 6 for both configurations analysed, there is a symmetrical deflection from the centre with a shape very similar to that of a bifixed beam, though in this case the curve does not increase progressively to reach a maximum deflection in the centre.
This symmetrical deflection angle is useful if average daily radiation conditions for the region are symmetrical about solar noon.
For each initial tilt angle [[beta].sub.0] the daily energy yield increases for each set of symmetrical deflections chosen.
