The device can absorb and utilize the solar energy for multiple times by using the solar energy absorption curved surface device and the solar energy absorption rod-shaped device, and two tracking modes can be used according to weather conditions, so that the performance and the effect of conventional solar power generation devices are greatly improved.

Description

【Technical field】 [0001] The invention relates to the technical field of solar power generation, in particular to a solar power generation device, a solar power generation system and a control method thereof. 【Background technique】 [0002] Due to the large consumption of traditional energy such as petroleum and coal, its limited storage capacity, and the serious pollution to the environment, people pay more and more attention to clean energy such as wind energy and solar energy. Abundant energy has increasingly become a research focus and focus. Solar power generation technology is different from solar heat generation technology that utilizes radiant heat energy emitted from the sun. The solar power generation technology utilizing unlimited clean energy has several advantages, including: no additional energy or driving source is required, and it has a simple structure whether it is a small system or a large system. [0003] The renewable energy utilization efficiency of t...

Problems solved by technology

[0004] The traditional solar concentrator uses a parabola to reflect the solar energy through the parabolic mirror, and then concentrates the sunlight at the center of the parabola, where the solar energy continues to increase, and people can usually use the solar energy concentrated at this point for heating operations, through such The equipment can think of such an idea: if the parabolic mirror of the concentrator is converted into a solar cell and made into a parabolic solar power generation device, it can absorb sunlight and generate electricity. However, after analysis, we will find that if we want to achieve This design is unreasonable to absorb sunlight twice or multiple times, because according to the principle of the solar concentrator, if the sunlight is reflected by the parabolic device, it will still gather at the center of the sphere, and the energy here will become more and more High, it is impossible what kind of photoelectric conversion equipment can withstand such a temperature, so if you want to absorb the reflected solar energy again, you must disperse the reflected solar energy
