Multi-spectral measurement type light resource monitoring method and system

Abstract

The invention discloses a multi-spectral measurement type light resource monitoring method and system. The multi-spectral measurement type light resource monitoring method comprises implementing the measurement of the irradiance of the solar radiation in the multi-spectral range through a plurality of channels and combining an indium, gallium and arsenic pin photoelectric detector of a broadband and a light filter with a silicon photodiode detector to implement the multi-spectral light resource monitoring based on measurement data of the irradiance of the solar radiation in the multi-spectral range. According to the multi-spectral measurement type light resource monitoring method and system, the defects that the equipment types are less, the applicable range is small, the measurement accuracy is low, and the like in the prior art can be overcome so as to implement the more equipment types, large applicable range and high measurement accuracy.

Description

technical field [0001] The present invention relates to the technical field of solar light resource monitoring, in particular to a method and system for multi-spectral measurement of light resource monitoring. Background technique [0002] In order to better develop and utilize solar energy resources, it is necessary to demonstrate the climate feasibility of large-scale solar resource development and utilization projects. When designing solar cell application systems, it is necessary to grasp the solar radiation energy reaching the area, that is, to grasp the annual, monthly total. Ground solar radiation includes direct radiation and diffuse radiation. When solar radiation passes through the earth's atmosphere, it is not only scattered by air molecules, water vapor and dust in the atmosphere, but also absorbed by oxygen, ozone, water and carbon dioxide in the atmosphere, and the intensity of solar radiation reaching the ground through the atmosphere is significantly attenua...

Problems solved by technology

[0004] In fact, due to the different frequency bands covered by different types of solar cells, it is difficult to effectively evaluate light resources only by using a single monitoring parameter.

In order to overcome the shortcomings of single domestic solar radiation measurement products, limited spectral coverage of different products, and low measurement accuracy, it is absolutely necessary to study professional monitoring methods and equipment from the perspective of energy utilization and development.

[0005] In the process of realizing the present invention, the inventor found that there are at least some defects in the prior art, such as few types of equipment, small scope of application, and low measurement accuracy.
