Evaluation of Solar System in Complex Environment

Due to the complex mountainous construction environment, solar panel working efficiency is affected by multiple dimensions of the external environment. For research the relationship between generated electricity and environment factors, a method used with combine three-dimensional modeling with radiation models to assess generated electricity in solar system. Firstly, by importing the relevant solar radiation data from a data system, Meteonorm, into the traditional Hay radiation model to construct a highly accurate model to process radiation resource calculation. Finally by comparing devices factor change, such as azimuth angle, tilt angle, and light radiation scattering, to assess solar system. The simulation results indicate that slight changes in tilt and azimuth have a small impact on the photovoltaic system, while changes in radiation reflection and diffusion caused by height adjustment of photovoltaic modules have a significant impact on the overall power generation.
