Problems solved by technology

[0004] But this mainstream photovoltaic power generation method has obvious defects: ①Low light utilization rate, the power generation of solar cells is proportional to the effective radiation area, the effective radiation area is the projected area of ​​received sunlight on the vertical surface of sunlight
Due to the rotation of the earth, the sun rises in the east and sets in the west every day. The solar cells of the fixed flat-panel photovoltaic power generation are only facing the sun for a short time in a day. The cosine of the angle between the vertical planes. At this time, the solar cells do not make full use of sunlight, so a lot of solar radiation energy will be wasted, so the light utilization efficiency of fixed flat-panel photovoltaic power generation is low.
[0005] ② The amount of solar cells is large, and the solar radiation power is very low, only about 1kw per square meter. Therefore, to achieve a certain power generation power, a large number of solar cells are required, and the manufacturing process of solar cells is complicated and energy consumption is high, resulting in the cost of photovoltaic power generation. Too high, lack of market competitiveness

Abstract

The invention discloses a reflective low-concentration photovoltaic generator which comprises a sunlight receiving assembly and a supporting mechanism for supporting the sunlight receiving assembly, wherein, the sunlight receiving assembly comprises solar cell modules and sunlight reflecting components which are distributed at equal intervals; and the sunlight reflecting components are arranged at two sides of the solar cell modules and respectively form an included angle alpha within 90-135 degrees with the corresponding solar cell modules. In the invention, the sunlight reflecting components are arranged at two sides of the solar cell modules and the included angle is formed between the sunlight reflecting component and the solar cell module, therefore, the solar cell modules with a certain area can receive more sunlight to improve generated electric energy; and meanwhile an azimuth angle driving device and an altitude angle driving device can effectively control the sunlight receiving assembly to be always vertical to the sunlight irradiation direction, thus completing tracking of the sun and keeping the sunlight receiving assembly in a maximum operating condition.

Description

technical field [0001] The invention relates to the field of solar photovoltaic power generation, in particular to a reflective low-magnification concentrated photovoltaic generator. Background technique [0002] Energy and the environment are topics of great concern to all mankind. At present, the huge energy consumption of human society is mainly supported by the three conventional fossil energy sources of coal, oil, and natural gas. The use of conventional fossil energy is not only serious pollution, but also very limited resources. Based on the above reasons, solar energy, which is green and environmentally friendly and can be used infinitely, is regarded as an ideal alternative energy source, and people's development and research on it are also very active. [0003] The utilization of solar energy has two main forms: photothermal and photovoltaic, among which the research and utilization of photovoltaic develops fastest. Solar photovoltaic power generation uses solar c...
