Description
The invention relates to the technical field of solar energy, in particular to a single-axis tracking system for enhancing light intensity of a component.
Currently, energy is a cornerstone existing and developing in modern society. The application technology of solar energy as an important component of renewable energy has become a mark for measuring the overall strength of a country. China has large resource reserves, but the quantity of all people is always lower than the quantity of all people all around the world, and in addition, china is a large energy consumption country, and the objective conditions require that other available energy sources are adopted to relieve the energy crisis to be faced by China. Because of the universality, richness, cleanness and permanence of solar energy utilization, the large-scale development and utilization of solar energy are inevitable choices for realizing sustainable development facing the future under the background that the supply of fossil energy is increasingly tense.
The utilization of solar energy has two main forms of photo-thermal and photovoltaic, wherein the research and the utilization of photovoltaic are the fastest. Solar photovoltaic power generation uses a solar cell as a photoelectric conversion device to convert solar energy into electric energy.

However, the mainstream photovoltaic power generation mode has obvious defects: 1) The light utilization rate is low, the power generation amount of the solar cell is in direct proportion to the effective radiation area, and the effective radiation area is the projection area of received sunlight on the sunlight vertical plane. The sun rotates, the sun rises and falls every day, the solar cell for fixed flat plate photovoltaic power generation only faces the sun for a short time in one day, when the solar cell faces the sun obliquely, the effective radiation area of the solar cell is in direct proportion to the cosine of an included angle between the solar cell and a sunlight vertical plane, and the sun is not fully utilized by the solar cell, so that a large amount of solar radiation energy is wasted, and the light utilization rate of the fixed flat plate photovoltaic power generation is low.
2) The solar cell has large consumption and low sunlight irradiation power which is only about 1kw per square meter, so a large amount of solar cells are needed to reach a certain power generation power, and the manufacturing process of the solar cells is complex and has high energy consumption, so that the photovoltaic power generation cost is too high and the market competitiveness is lacked
Therefore, it is necessary to provide a technical solution to solve the above problems.
