Abstract

This paper provides a method for thermoelectricity coupled simulation of the photovoltaic wall. Based on the equivalent circuit model and the relationship between the operating temperature of photovoltaic modules and the thermal characteristics of photovoltaic wall, a one-dimensional unsteady heat transfer model considering multiple boundary conditions is established, and the operating temperature of the photovoltaic module is calculated, then the value is again coupled into the dynamic power model of photovoltaic modules to achieve the accurate simulation of the photovoltaic power generation performance and the heat transfer process of photovoltaic wall. The above decoupling and recoupling processes between heat transfer and power generation performance fully consider the effects of multiple environmental factors and multiple boundary conditions on the power output and unsteady heat transfer of the components, as well as the coupling between thermal and electrical properties. By simulating the power generation performance and thermal performance of photovoltaic wall in winter and summer in Nanjing, the correctness of the proposed method was preliminarily verified, and the problems of photo-electricity-heat combined simulation of the solar photovoltaic wall are solved.
