Abstract: A solar reflection apparatus (60) is disclosed comprising a rotatable reflection (assembly 20) and a drive mechanism (12) which is operable to drive rotation of the reflection assembly (20) at its axis of rotation. The reflection assembly (20) comprises a curved linear reflector (4) defining a focal axis F, a counter weight (17) operable to balance the self weight of the reflector (4), and a support structure (15) via which the reflector (4) and counter weight (17) are rotatably mounted at locations along the focal axis F of the reflector (4). A solar collection apparatus (2) is also disclosed comprising a solar reflection (apparatus 60) as disclosed above and a heat collecting element (6), fixedly mounted along the focal axis F of the reflector (4).
