Abstract

The basis for the function of a linearly concentrating solar collector lies, in simple terms, in the fact that reflectors reflect incident sunlight onto a receiver tube through which a heat-absorbing medium flows. Owing to the rotation of the Earth, the reflectors need to be adjusted regularly, however, in order to ensure that the sunlight hits the receiver tube. Known tracking methods use calculated positions of the sun for this purpose, which, in the case of structural deviations, for example as a result of expansion and material stress, results in inaccuracies and losses in efficiency. The invention is intended to improve the tracking of the reflectors in such a linearly concentrating solar collector. This is achieved by virtue of the fact that the radiation intensity in the region on both sides next to the receiver tube is measured and, by means of regulation, in the case of uneven emission on both sides of the receiver tube, the reflectors are tracked to such an extent that the radiation intensity on both sides of the receiver is the same and thus the maximum of the radiation intensity is on the receiver tube.
