Heat storing solar collector device
Patent
·
OSTI ID:5778440
A solar collector device is placed on a floating insulating lid of a reservoir containing a heat storing liquid. The solar collector device comprises lens means which concentrate incident solar radiation to focal points or focal lines rear or at the lid , and the lid has apertures through which the focus portions of the radiation beams pass with snug clearance. Transparent evaporation preventing diaphragms seal the apertures. Electricity generating semi-transparent solar cells may be arranged in the apertures, whereby incident solar radiation partly produces electricity, partly heats the liquid, and whereby the liquid cools the cells. In the case the lens means comprise axially elongated lenses in parallel with the lid and the apertures are slots, aligned with the lens axes, the lid is rotatable whereby to maintain the lens axes, the slots and the sun radiation in one and the same plane during day time.
