A solar tracking unit for concentrating the sun's rays on an absorption receptor includes one or more concave reflectors and an energy absorption receptor disposed between the sun and the reflector. An energy absorbing fluid flows through the receptor and is heated by the concentrated rays of the sun. A first plurality of photovoltaic cells are disposed about a hemispherical form for generating an electrical signal to incrementally rotate the reflector about a first axis and a second plurality of photovoltaic cells disposed about a hemispherical form to generate an electrical signal to rotate the mirror about a second axis to thereby focus the reflected rays on the receptor.
