Analytical methods for parameter estimation of PV cells In a large number of research works, analytical methods have been used to extract model parameters of PV cells. In this section, those research work are classified based on their used PV cell model and will be analysed. 3.1.1.
PV cell model parameter estimation is a hot research topic in renewable energy. In this paper, different circuit models of PV cells have been described and the existing research works on PV cell model parameter estimation problem have been categorised into three categories and the research works of those categories have been reviewed.
This paper proposed a simple and effective method to evaluate the PV cell equivalent circuit parameters at STC, regardless of the power rating of the PV cell. Each parameter is formulated by a mathematical model that can be easily and instantly evaluated by just using the information provided in the datasheet.
Although, there exist other ways for modelling PV cells, circuit models are the most popular ways for modelling PV cells. Finding the circuit model parameters of PV cells is referred to as “PV cell model parameter estimation problem” and represents a challenging problem in the field of renewable energies.
