A growing dual-plane mirror reflective photovoltaic intelligent concentrating system

Abstract

The invention discloses a prolonged double-plane mirror reflection photovoltaic intelligent condensation system and belongs to the technical field of solar application. The prolonged double-plane mirror reflection photovoltaic intelligent condensation system comprises a condensation battery panel component bracket, a battery panel component, two plane mirrors symmetrically arranged to the battery panel component in 120 degrees, an upper mirror stand and a lower mirror stand respectively fixed with the plane mirrors, a triangular floor stand, and a plurality of flange rollers. The length of each of the two plane mirrors is larger than that of the battery panel component. Through regulating automatically or manually, when the battery panel component is arrayed in the east-west direction, the battery panel component always faces to the sun at the high noon of each day, and when the battery panel component is arrayed in the south-north direction, the battery panel component completely tracks the sun from the east to west at each day. The prolonged double-plane mirror reflection photovoltaic intelligent condensation system has features that the manufacturing technique is simple, the cost is low, the solar energy utilization efficiency is improved in all time, and the photovoltaic power generation capacity is obviously improved.

[0002] At present, there are many ways to increase the efficiency of solar energy utilization in China. Various schemes of concentrating photovoltaic power generation systems are the most common. One is to use large-scale parabolic reflection and concentrating light, but the disadvantages are that it is difficult to manufacture, high in cost, and the overall windproof performance is poor.

In order to reduce manufacturing costs, various technologies of using flat mirrors to reflect solar photovoltaic power generation have begun to be widely used, such as the utility model patent No. ZL200920031702. Reflecting sunlight to the photovoltaic module can theoretically increase the light intensity significantly. However, due to the multi-faceted flat mirror, the system structure is complicated, the manufacturing cost is high, and the maintenance is inconvenient; , the amount of power generation depends on the panel with the least light, so uneven light is an important factor affecting the power generation of the panel components. , the light intensity of sunlight obliquely irradiating the photovoltaic modules is extremely uneven, and the sunlight cannot be reflected by the plane mirror to the two ends close to the battery panel components, so that in the whole string of battery panel components, only the panels with a small power generation can be obtained The output power of the string and the utilization efficiency of solar energy are greatly reduced
