The Research Of Pv Sound Barrier Of Solar Energy

With the depletion of non-renewable energy resources and increasing environmental pollution,the human must take measures to develop and exploit renewable energy. On the other hands, with the development of urban road construction and transport industry, traffic noise pollution will become seriously, it led to widespread attentions, and the human is actively exploring effective measures to control traffic noise. The PV sound barrier of solar energy has the capabilities which can absorb sound and generate power; it has huge market potency. This paper made in-depth study on the solar sound barrier and designed a PV noise barrier based on acoustic resonance structure; it had a detailed study on the new PV noise barrier loss affection and photoelectric conversion efficiency by the experiments.(1) This paper studied the acoustic characteristics of road noise barrier and analyzed the theory of sound barrier; furthermore, it discussed the methods of sound barrier insertion loss calculation of different sound sources and the noise barrier design. It identified geometric shape and position of highway noise barriers. These studies will provide a theoretical basis for studying the feature of acoustics solar PV noise barriers comprehensively and widely.(2) This paper studied the mechanism of absorption sound for the resonant structure of the perforated plates absorption sound and established theoretical model of the resonant frequency, It designed a new solar PV sound barrier of the absorption sound resonance structure and made use of standing wave tube by the experiment study the low frequency and high frequency sound absorption coefficient of different acoustic resonance structural parameters. We found that the new structure of the noise barrier absorption by the experiment and confirmed the structural parameters of the best reduction noise effect.(3) We research the noise barrier photoelectric conversion efficiency deeply, and analyzed photoelectric output characteristics of PV noise barrier in the same light intensity and temperature with different structural parameters, It made a contrast in photoelectric conversion with monocrystalline silicon solar panels and confirmed PV noise barrier parameters and working conditions which had the best photoelectric conversion efficiency.
