The solar collector has a V-corrugated aluminum-coated
black absorbing plate. The absorbing plate has a 60 angle
aperture-channel, which allows it to have a 3.2 m2 effective
area of incidence at midday. The double glass cover system
is 0.006 m thick with a separation of 0.05 m between the
glass covers. The width of the absorbing plate is 1.095 m.
The collector is stationary, with a 40 angle of inclination
with respect to horizontal. The bottom and sides are isolated
with expanded polystyrene, 0.019 m thick (Fig. 2).
