TL;DR: In this paper, a rotational paraboloid is used as a pivot mounting for a solar energy collector, where the reflectors are mounted on a number of spaced struts with a parabolic support face.
Abstract: The solar energy collector has a carrier plate (27) on which one or more parabolic reflectors (26) are mounted. The opposite surface of the carrier plate (27) carries a zig-zag metal or plastics reinforcing element (28). The surface of the carrier plate (27) on which the reflectors (26) are mounted pref. has a number of spaced struts (29), each with a parabolic support face (30), on which the parabolic reflectors rest. The carrier plate (27) may have the form of a rotational paraboloid and be carried by a pivot mounting for focussing the solar energy collector.

TL;DR: In this article, a device for testing focal spots focused by a solar parabolic concentrator was proposed, which takes full advantage of the linear beams generated by a semiconductor laser and tests the focused focal spots through reflection of a parabolic mirror.
Abstract: The invention relates to a device for testing focal spots focused by a solar parabolic concentrator. The device takes full advantage of the linear beams generated by a semiconductor laser and tests the focused focal spots through reflection of a parabolic mirror. The device is simple and the method is feasible and is widely applied to various parabolic concentrators. The device belongs to the technical field of solar energy utilization.

TL;DR: In this article, a solar energy concentrating system with high light collection efficiency includes a light concentrating unit, a light homogenizing unit and photovoltaic modules including a parabolic reflector and an ellipsoidal reflector which are coaxial and confocal.
Abstract: A solar energy concentrating system with high light collection efficiency includes a light concentrating unit, a light homogenizing unit and photovoltaic modules The light concentrating unit includes a parabolic reflector and an ellipsoidal reflector which are coaxial and confocal The light homogenizing unit includes an infrared filter and a hollow spherical reflector with a hole in its surface When the system is under illumination, light is concentrated by the light concentrating unit through the hole in the spherical reflector surface and reflected by the inner surface of the spherical reflector onto the photovoltaic modules The infrared filter covers the hole in the spherical reflector surface and reduces the heat in the photovoltaic modules under concentrated light The combination of the parabolic reflector and the ellipsoidal reflector obtain highly concentrated light, and the hollow spherical reflector ensures light uniformity on the photovoltaic modules and light utilization efficiency
