PHOTOVOLTAIC PANEL STRUCTURE CAPABLE OF REDUCING INFLUENCE OF DUST ACCUMULATION AND METHOD FOR DESIGNING PHOTOVOLTAIC PANEL STRUCTURE

The present invention relates to a photovoltaic panel structure capable of reducing influence of dust accumulation and a method for designing a photovoltaic panel structure. The method comprises: obtaining a dust accumulation sample, and measuring a particle size distribution function f(R) and a relative dielectric constant thereof; calculating a near field of particles subjected to electromagnetic waves by a Mie scattering theory, and the formula is as follows: obtaining scattered field data of particles with different particle sizes (R) under solar radiation with a wavelength of A by simulation calculation, finding a corresponding distance r when field intensity is greater than a fixed value b, establishing a corresponding fitting function, and thereby calculating an average distance; and selecting ; as the thickness of photovoltaic glass, and assembling the photovoltaic panel structure accordingly. The present invention designs a photovoltaic glass structure by obtaining the physical property of local dust accumulation and the power spectrum of solar radiation in advance, so as to realize high-efficiency power generation of photovoltaic cells.
