Abstract

The invention relates to a concentrating photovoltaic light-guiding component, in particular to a concentrating solar power generation light-guiding hopper, and belongs to the technical field of solar power generation. The concentrating solar power generation light-guiding hopper comprises a light guiding hopper body, a connecting plate and fixing installing holes, wherein the lower port of the light guiding hopper body is directly welded to the connecting plate, the upper port and the lower port of the light guiding hopper body are both rectangular, and the two fixing installing holes are formed in the two opposite surfaces of the connecting plate respectively. According to the concentrating solar power generation light-guiding hopper, the light guiding hopper body is simple in machining process and product structure, low in material consumption and light in weight. The light guiding hopper body cannot deform in the packaging and transport process and the follow-up installing process, and meanwhile it is ensured that converged sunlight completely concentrates on the effective surface of a concentrating photovoltaic cell chip. In addition, focal spots converged through a Fresnel lens will converge on the effective area of a concentrating solar cell chip in a complete superposition mode through the light guiding hopper body in a certain time period. A motor of a solar energy tracker can only work one time in a set time period, and therefore the power supply power for the motor is greatly reduced, and more energy is saved.

Description

A kind of concentration solar generating leaded light funnel
Technical field
The present invention relates to a kind of condensation photovoltaic light guide member, be specifically related to a kind of concentration solar generating leaded light funnel, belong to solar energy generation technology field.
Background technology
In light gathering photovoltaic power generating system, mainly utilize lens that sunlight is converged on the significant surface of condensation photovoltaic battery chip, thereby reach the object of generating.The lens that use at present, general convergence rate is in 80% left and right, and according to the conversion efficiency of every raising 1% of current measuring and calculating, the decline of its electricity price nearly 5%, has now become one of important topic of each business research so improve the convergence rate of lens.
It is current that to have Some Enterprises be by leaded light funnel, to improve the convergence rate of lens, although leaded light funnel has good light-guiding function, but due to L-shaped or right angle " Z " font of its connecting plate (fixed installation pin is also in some place), directly from the upper port of leaded light funnel, connect, producing, in packed and transported or later stage installation process, right angle is not easy to obtain the assurance of 90 °, thereby make leaded light occur deviation to the light face of condensation photovoltaic battery chip significant surface, cause the reduction of photovoltaic conversion efficiency; The material using due to " L " or " Z " font product more than " one " font simultaneously, add that the leaded light funnel quantity that each concentrating photovoltaic assembly uses is extremely many, so concentrating photovoltaic assembly overall weight will increase, process in addition also more complicated of " L " or " Z " font technique.
Conventionally the focal spot converging from Fresnel Lenses is at present all square, the shape of the shape of this focal spot and big or small also common and concentrating solar battery sheet and in the same size, thus the focal spot that Fresnel Lenses converges is converged on concentrating solar battery sheet completely by leaded light funnel.But in actual applications, the sun is at any time mobile, can be not completely will causing like this focal spot that converges from Fresnel Lenses after the time period by leaded light funnel and the effective area of concentrating solar battery sheet overlap, thereby cause the reduction of conversion efficiency.
Summary of the invention
The invention provides a kind of concentration solar generating leaded light funnel, this leaded light funnel technical problem to be solved is to overcome the deficiencies in the prior art.
In order to realize above-mentioned technical purpose, the technical scheme that the present invention takes is: a kind of concentration solar generating leaded light funnel, it is characterized in that, it comprises leaded light funnel, connecting plate and fixed installation hole, described leaded light funnel lower port is directly welded on connecting plate, and two ports up and down of described leaded light funnel are rectangle, is provided with two fixed installation holes on relative two faces of described connecting plate.
The metal material parts that described leaded light funnel is a conical by its shape, the side that comprises upper and lower two ports and four isosceles trapezoids, the area of upper port is greater than the area of lower port, and upper and lower two ports are rectangle, the difference of the length and width of upper port is 0.02 ~ 10mm, and the difference of the length and width of lower port is 0.01 ~ 1mm.
The lower port shape of described leaded light funnel and size are in full accord with significant surface shape and the size of concentrating photovoltaic cell slice.
Described connecting plate is the metal material parts of " π " glyph shape, is provided with two fixed installation holes on relative two faces of connecting plate.
Advantage of the present invention and good effect are: 1. this leaded light funnel processing technology is simple, and product structure is simple, and consumptive material is few, lightweight; 2. this leaded light funnel can not be out of shape in packed and transported process and subsequent installation process, has guaranteed that the sunlight after converging gathers on the significant surface of condensation photovoltaic battery chip completely simultaneously; 3. the focal spot converging from Fresnel Lenses can all be overlapped completely and be converged in the effective area of concentrating solar battery sheet by leaded light funnel in certain hour section; 4. set the machine operation of a time period solar tracking device once, so just greatly reduced the output power to motor, thus more energy-conservation.
