Solar power station

Abstract

The invention discloses a solar power station, which comprises a plurality of concentrated solar cell monomer modules which are electrically connected. Each monomer module comprises a condensing lens, a solar cell semiconductor chip, a horizontal and pitching rotation driving mechanism for driving the monomer module to carry out horizontal and pitching motion by following the sun. The plurality of concentrated solar cell monomer modules form module arrays which are arranged in mutually-spaced L distance along the horizontal direction, and the L meets a relational expression that L is equal to W / cosine alpha, wherein in the formula, W is the width of the concentrated solar cell monomer modules, and alpha is a solar azimuth determined by the latitude theta of a mounting site of the power station. The power station has low requirement on the mounting site and position, is not easy to damage under strong wind, and is convenient to mount and maintain; and the arrangement structure of the concentrated solar cell monomer modules in the power station and the distance of mutual intervals are reasonable, the occupied area is small, and the monomer modules are not mutually affected during working and can absorb sunlight more effectively so as to achieve maximum generating efficiency.

Description

technical field [0001] The invention relates to a power station, in particular to a solar power station composed of several solar battery monomer modules that automatically track sunlight and generate electricity in a concentrating manner. Background technique [0002] With the depletion of traditional resources such as oil and coal, solar energy has been widely used as a new energy source. At present, there are roughly two types of solar power stations commonly used. One is to use a plurality of large-area solar panels composed of solar battery arrays, and to drive the solar panels to follow the sun for horizontal rotation and pitch rotation. A solar power station composed of a large-area solar panel and a power generation unit composed of a mounting frame for a driving mechanism. Such a power generation unit has been described in detail in Chinese utility model patents, patent numbers 02218387.6 and 200620090366.3, etc.; However, in such a solar power station, due to the ...

At present, there are roughly two types of solar power stations commonly used. One is to use a plurality of large-area solar panels composed of solar battery arrays, and to drive the solar panels to follow the sun for horizontal rotation and pitch rotation. A solar power station composed of a large-area solar panel and a power generation unit composed of a mounting frame for a driving mechanism. Such a power generation unit has been described in detail in Chinese utility model patents, patent numbers 02218387.6 and 200620090366.3, etc.; However, in such a solar power station, due to the large volume of the power generation unit, the occupied area of ​​the power station is also large, and because the windward area of ​​the power generation unit is large, the power station formed by it is easily damaged under strong winds. Therefore, Such a power station has high requirements on the installation site and location. In addition, larger hoisting equipment must be used during installation, and maintenance must be carried out by professionals and special equipment, so installation and maintenance are also very inconvenient; One is a solar power station composed of several concentrating solar cell modules that are electrically connected. In the power station, each concentrating solar cell module has independent sunlight automatic tracking capabilities. The light solar cell module is mainly composed of a Fresnel lens, a solar cell semiconductor chip, a horizontal rotation drive mechanism that drives the concentrating solar cell module to follow the horizontal movement of the sun, and drives the concentrating solar cell module to follow the sun. It is composed of a pitching and rotating drive mechanism for pitching motion; a solar power station with such a structure has lower requirements on the installation site and location, and can make better use of various complex terrains, barren mountains and wild ridges, and various types of buildings. And the formed power station is not easy to be damaged under strong wind, and the installation and maintenance are also relatively convenient. However, since the individual concentrating solar cell modules constituting the power station are placed randomly during installation, this often makes the arrangement of the monomer modules The structure and the distance between each other are very unreasonable, which not only makes the power station occupy more land area, but also often causes the mutual influence between the individual modules during work, so the solar energy cannot be better utilized to achieve the maximum power generation efficiency
