Solar conversion apparatus comprising: concentrating means for concentrating solar energy onto at least one surface; tracking means for causing the concentrating means to track the sun, said tracking means including radiation sensitive elements which are operable on differential thermal expansion thereof to generate tracking control signals and an electric motor for moving said concentrating means, said motor being responsive to said control signals; and over temperature sensing means operable to override said tracking means and cause the motor to move the concentrating means out of alignment with the sun. Solar conversion apparatus comprising concentrating means for concentrating solar energy onto at least one surface, tracking means for causing the concentrating means to track the sun, said tracking means including first radiation sensitive elements which are responsive to thermal components of solar radiation and are operable to produce first control signals for initiating tracking movements of the concentrating means and at least one second radiation sensitive element which is responsive to non-thermal components of solar radiation and is operable to produce second control signals for arresting tracking movements of the concentrating means. A method of collecting solar energy comprising moving solar energy concentrating means such that the concentrating means concentrates solar energy on a heat transfer surface; generating control signals by means of at least one element which is sensitive to infra-red components of solar radiation for initiating tracking movements of concentrating means toward alignment of the concentrating means with the sun; and generating an arresting signal by means of at least one element which is sensitive to visible or ultra-violet components of solar radiation for arresting tracking movements of the concentrating means when the concentrating means is correctly aligned with the sun. *** BRS DOCUMENT BOUNDARY ***
