A solar collector includes a plurality of elongate parallel reflectors mounted for rotation about their respective longitudinal axes, together with mechanism coupled to the reflectors for simultaneously rotating the same. An elongate absorber is arranged parallel to the reflectors for collecting solar radiation focussed thereon by the reflectors. Tracking means including two solar sensor reservoirs containing a vaporizable/condensible liquid working medium is provided for rotation of the reflectors to control the focussing of solar radiation on the absorber.

A solar collector, which comprises a plurality of elongate, mutually parallel individual reflectors mounted on a frame for rotation about their respective longitudinal axes, an adjusting mechanism coupled to the individual reflectors for simultaneously rotating the same, an elongate absorber arranged parallel to the individual reflectors and serving to collect solar radiation focussed and concentrated thereon by the reflectors, and tracking means responsive to solar radiation for operating the adjusting mechanism, said tracking means including two elongate sensor reservoirs positioned opposite the reflectors and extending, when viewed from the reflectors, at least substantially on different sides of the absorber relative to each other, one end of each reservoir being situated in the immediate vicinity of the absorber, a vaporizable/condensible working medium partly in the liquid phase and partly in the vapour phase in each reservoir, the vapour pressure of said working medium in each reservoir being proportional during operation to the quantity of solar radiation received from the reflectors by the respective reservoirs, and means to enable the two working medium vapour pressures to act on the adjusting mechanism in mutually opposed senses to correct the focussing of solar radiation by the reflectors on the absorber in accord with any differential working medium vapour pressure.
