Abstract

The invention provides a photovoltaic generator of plane network support two-dimension sun track, belonging to the technical field of solar-energy photovoltaic generation. The invention comprises a solar-energy photovoltaic generator and a sun tracker, wherein the sun tracker is a two-dimension track device, which comprises a horizontal rotary support, an inclined swing support, a vertical fixed shaft, a horizontal shaft, a sun direction track driver, and a sun altitude angle track driver. The solar-energy photovoltaic generator can be provided with a condenser and a self heat radiation in disc or groove shape while a plurality of photovoltaic generators are mounted on a plane network support of the inclined swing support. The horizontal rotary support rotates around the vertical fixed shaft. The inclined swing support rotates around the horizontal shaft. Therefore, the normal line of the photoelectric battery plate of the solar-energy photovoltaic generator is toward sun all the time. The invention has stable structure, small drive force, multiple load of elements, saved track cost, improved condense ratio caused by the utilization of condenser and self heat radiator, and improved generating efficiency.

Description

Technical field:

[0001] The invention relates to the field of solar photovoltaic power generation, in particular to a solar photovoltaic generator tracking mechanism for the sun. Background technique:

[0002] At present, the photovoltaic power generation method of solar energy generally allows sunlight to be projected on a flat-plate solar panel with a fixed inclination angle. The photovoltaic cells used are mainly monocrystalline silicon and polycrystalline silicon semiconductor materials, and the power generation efficiency is about 14% of the projected solar radiation power. ~16%. Photovoltaic cells with multilayer P-N junctions can be used for focused photovoltaic power generation, but they are too expensive, so they are only used in small quantities. The biggest problem with solar photovoltaic power generation is that the investment in power generation equipment is too high and the cost of power generation is too expensive. The main reason is: the cost of photovoltai...
