Abstract
The invention provides a solar light-gathering panel. The upper surface of the panel is a plane, and along the width direction, the plane is uniformly divided into a plurality of solar light-gathering panel units whose widths are the same. The cross sections of the lower surfaces of the solar light-gathering panel units are curves. Parameters of each curve are different. A curve group is formed on the width direction of the solar light-gathering panel. The reflection focuses of the curve group are gathered on a main focus. The curve group extends along the length direction of the solar light-gathering panel to form a curved surface group, so that the main focuses form a line along the length of the solar light-gathering panel, and sunlight is focused on the line. The curved surface group form zigzag grooves on the lower surface of the solar light-gathering panel. The surfaces of the zigzag grooves are plated with a layer of reflection coating. The solar light-gathering panel uses the Fresnel principle, and process is simple and manufacturing cost is low.
