AI Technical Summary

Technical Problem

Existing technologies for simulating natural dust accumulation suffer from uneven dust distribution and fail to consider the influence of photovoltaic panel installation angles, resulting in large deviations between simulation results and natural conditions, poor repeatability, and impacting the accuracy of photovoltaic power generation efficiency assessments.

Method used

An adjustable-angle platform and air supply system are used, combined with natural wind speed control. Pre-treated natural dust is released into the closed test area through natural settling and wind drive. The amount of dust is calculated by uniform distribution of the ultra-clear cover glass and the difference in mass, thus achieving standardized simulation.

Benefits of technology

Precisely control dust distribution and quantify dust accumulation levels to improve the repeatability of experimental results, provide standardized experimental procedures, and support research on dust accumulation on photovoltaic panels and evaluation of power generation efficiency.

Abstract

The invention discloses a method and system for manufacturing a standard dust retention photovoltaic panel by simulating natural dust retention, and belongs to the technical field of photovoltaic dust retention detection. A target inclination angle is set through an objective table with an adjustable angle, a constant wind speed and a closed experiment environment are combined, pretreated natural dust is put, and a dust deposition process of a photovoltaic panel in an actual installation state is truly restored by utilizing a synergistic effect of natural sedimentation and wind power, so that the problem that an inclination angle parameter cannot be simulated in the prior art is solved; a uniform surrounding distribution structure of ultra-white cover plate glass is adopted, and standardized calculation is performed by weighing a mass difference value before and after dust accumulation and combining with a glass area parameter, so that the dust accumulation distribution uniformity is verified, and the experiment repeatability is improved; the dust accumulation degree is accurately controlled by adjusting the parameters such as the dust throwing amount, the wind speed and the inclination angle, the actually measured data of the cover plate glass is converted into the dust accumulation amount of the unit area of the standard photovoltaic panel, the problems that in the prior art, authenticity simulation is insufficient, distribution is uneven, and quantification is difficult are solved, and a standardized experiment scheme is provided for photovoltaic panel dust accumulation research.
