Detection method and apparatus for cleanliness of photovoltaic panel

Abstract

The invention specifically relates to a detection method and apparatus for the cleanliness of a photovoltaic panel, belonging to the field of detection technology for the cleanliness of solar photovoltaic panels. The method detects the cleanliness of the photovoltaic panel by measuring the intensity of modulated laser beam signals scattered by the photovoltaic panel. The matching apparatus comprises a cleanliness sensor and a signal processing device. The cleanliness sensor comprises a laser, a modulation device, a convergent lens and a detector and is mainly used for accomplishing collection of scattered light and photoelectric conversion; and the signal processing device comprises a DC regulated power supply, a signal processing circuit, a microprocessor and a communication circuit and mainly used for AD conversion, amplification and transmission of electrical signals. The detection method and apparatus have the advantages of high measurement precision, simple structure, cost performance, practicability, easiness in operation, strong anti-interference capability, capacity of easily realizing on-line measurement, etc.

Description

technical field [0001] The invention relates to a cleanliness detection technology of a solar photovoltaic panel, in particular to a method and a device for detecting the cleanliness of a photovoltaic panel by light scattering. Background technique [0002] Solar energy generally refers to the radiant energy of sunlight. With the decrease of fossil fuels, solar energy has become an important part of energy used by human beings and has been continuously developed. Photovoltaic power generation technology has gradually developed and matured, which can generate new and pollution-free renewable energy, and has been widely used at home and abroad. [0003] As the carrier of photoelectric conversion, photovoltaic panels play a vital role in the efficiency of photoelectric conversion. In order to receive more light, photovoltaic panels are mostly placed outdoors, and dust often falls on photovoltaic panels, which will have a serious impact on the power generation efficiency of pho...

Problems solved by technology

In order to receive more light, most of the photovoltaic panels are placed outdoors, and often there will be dust on the photovoltaic panels, which will have a serious impact on the power generation efficiency of the photovoltaic panels

In order for the staff to clean up the dust accumulated on the photovoltaic panels in a timely manner, it is particularly important to detect the cleanliness of the photovoltaic panels. However, in the existing technology, it is not possible to quickly measure the cleanliness of the photovoltaic panels and accurately provide real-time quantitative data.
