Solar automatic tracking system

Abstract

The invention discloses a solar automatic tracking system comprising hardware which has a smart structural design with single-axle scaly solar panels (1) and a universal joint bearing seat (5), and the solar automatic tracking system is suitable for a shaft support with multiple pillars, is mounted in complex hilly lands, has down-moved gravity of the support and flexible turning and enables the system to adopt a single-axis tracking system to establish a solar power station in bumpy hilly lands, thereby ensuring that the solar panels always obtain solar radiation energy as much as possible in the hilly lands, enhancing the tracking efficiency, effectively improving the anti-wind capability of the hardware, reducing the material breakage brought by windage resistance and strengthening the security and the adaptability. With a unique shadow elusion system processing function, the system prevents the solar panels on a stand from generating energy degradation because of being sheltered from mutual shadows and enables the solar panels to obtain the greatest energy output, thereby not only improving the solar electrical energy generation efficiency greatly, but also enhancing the adaptability of the solar tracking system and saving the limited resources by saving occupied space about 50 percent compared with the prior solar tracking system.

Description

1. Technical field [0001] The invention relates to solar power generation technology, in particular to a solar automatic tracking system for a large-scale solar power station with a relatively large area. 2. Background technology [0002] We know that only when the sun's rays shine directly on the solar panel, the panel can get the maximum power output. In order to improve the efficiency of solar panel power generation, it is an effective choice to use a solar tracking mounting system. Its function is to make the surface of the solar cell array automatically track and rotate as the sun moves in the sky, and try to keep it facing the sun vertically. At present, the solar panel support of the solar tracking system usually adopts a single-axis structure, and the solar panel installation method of the system is flat, that is, all the panels are fixed on a large horizontal frame. The traditional single-axis system has the following three problems: [0003] Problem 1. Since the...

Problems solved by technology

[0003] Problem 1. Since the single-axis system can only rotate in the east-west (longitude) direction to track the sun, the usual single-axis flat-panel system solar panels are fixed horizontally, and the effect is best only around the summer solstice. In other seasons, due to the north-south direction of sunlight The offset angle gradually becomes larger, resulting in the loss of sunlight

At the same time, its large windward area will form a large wind load. In order to resist the damage of the strong wind, the strength requirements of the structural parts must be increased, so that the consumables will increase and the cost will increase.

[0004] Problem 2. When the single-axis system is installed in a row in a large area, due to the land occupation factor, the allowable interval between the racks cannot be too large, so there will be shadows during the tracking process (see the figure below), causing some Open circuit of solar strings affects power output

[0005] Question 3. Since the single-axis system is a multi-column support structure, the fixed bearing seat usually used in the traditional single-axis system can only be installed on the flat ground as a whole frame, and cannot be adapted to a large number of installations on the complex terrain of mountainous areas with unevenness and different slopes. use
