Approach to Modeling Photovoltaic Energy Yield Using Chebyshev Polynomials

Year: 2026

Type: article

Abstract: Photovoltaic energy yield varies in response to changes in meteorological conditions. The main factors affecting the amount of electricity generated include solar irradiance and air temperature, as well as seasonal and daily variations. This paper examines the relationships between these factors and photovoltaic energy yield and presents an approach to modeling those using orthogonal Chebyshev polynomials. The main input variables, data-preprocessing steps, and structure of the approximation model are defined.
