The last three images show our webcam (at the top of the large
planetarium dome) and our meteo station. Some previous ones show the
roll-off roof in its usual closed position, reaching half a meter
from the white-painted 20cm concrete cube (which stabilizes thermally
the PV sensor, glued to it by gypsum). The closed roof as well as the
cherry tree at the corner casts relevant shadows onto the PV panel in
some occasions.
