<p>The solar energy collector comprises a solar energy converter (28), a base member (26) which carries the solar energy converter (28) and a domed fresnel lens (10) including a transparent hemispherical shell (12) mounted on the base member (26) over the solar energy converter (28) with a diametrical line across the base of the shell (12) being in register with a long axis of the solar energy converter (28), and fresnel lens prism elements (18) on the inner surface of the shell (12) which are each parallel to a plane (16) which passes through the pole of the shell (12) and the long axis of the solar energy converter (28) and which focus parallel ray solar radiation which passes through the shell (12) on either side of the plane (16) into a line focus on the solar energy converter (28) irrespective of the position of the sun relatively to the lens shell (12) while the sun is situated in the plane (16).</p> |
