Abstract
A solar-heating system incorporating a photosensitive sensor locatable remotely from the collector panels but similarly oriented with respect to the solar-energy source, such photosensitive sensor being biased by one or more biasing resistors of predetermined magnitudes and temperature coefficients so that the combination, in its performance with respect to ambient temperature and (optionally) with respect to ambient wind velocity, matches the thermal characteristics of the solar energy collection system so that the solar-energy collection fluid is pumped only when it can contribute heat energy to the already stored solar-heated fluid.
