Abstract

Experimental results obtained on a hybrid solar collector comprised of a photovoltaic cell and a thermal collector demonstrate that the electric power derived from imbedded photovoltaic panels can drive a fan to move the air heated in the solar thermal cell. The measured average thermal efficiency of the hybrid cell tested including the electric and thermal energy is typically 36%, but as demonstrated this can be significantly increased. The temperature of the heated air exiting the thermal cell, while being dependent on operating conditions, reached temperatures of the order of 50 oC. Measurements of insolation are used as a basis for evaluation of the efficiency of the cell. The hybrid cell was tested in horizontal, vertical, and normal to the sun configurations and a mathematical analysis is presented which correlates both the thermal and PV cell data for all cases. The hybrid cell could be operated as an independent automatically operated solar heater used to augment other heating systems.
