Abstract

The invention discloses a method and system for evaluating the quality of a photovoltaic module. The evaluation method includes: cleaning a photovoltaic module in a photovoltaic power station, and acquiring a cleaning effective time interval after the cleaning of the photovoltaic module; acquiring the original data of the photovoltaic module; correcting the original data to determine corrected data; training the corrected data and the cleaning effective time interval after the cleaning, establishing a related influence factor expert database and a secondary expert database; comparing the samephotovoltaic module in the related influence factor expert database and the secondary expert database under the cleaning effective time interval after cleaning, and determining the attenuation efficiency of the photovoltaic module; and evaluating the quality of the photovoltaic module according to the attenuation efficiency. The evaluation method and system provided by the invention can improve the quality evaluation accuracy of the photovoltaic module.

Description

technical field [0001] The invention relates to the field of photovoltaic power plants, in particular to a method and system for evaluating the quality of photovoltaic modules. Background technique [0002] As of the end of 2013, driven by recent national policies and relevant laws and regulations, the cumulative installed capacity of ground photovoltaic power generation in grid-connected operation across the country was 16.32 million kilowatts. From 2013 to 2015, the average annual installed capacity of photovoltaic power generation will be about 10 million kilowatts, and by 2015, the total installed capacity will reach more than 35 million kilowatts. [0003] With the continuous construction of photovoltaic power stations and the rapid growth of installed capacity, a large number of problems have gradually appeared in the operation of photovoltaic power stations in my country, such as low photoelectric conversion efficiency of photovoltaic power generation, high developmen...
