The equivalent electric circuit models reflect the electrical characteristics of the photovoltaic (PV) modules. Estimation of PV module parameters is considered as one of the challenging tasks while evaluating the performance. This article presents a new and useful approach to estimate the five-parameter PV module electrical circuit model. It translates the PV module parameter estimation process into an optimization problem using the information provided by the manufacturer on the rear side of the PV modules. It then employs an efficient metaheuristic technique, namely the backtracking search algorithm, to solve the developed optimization problem. The efficacy of the proposed approach is investigated by predicting the parameters of three PV module technologies: monocrystalline, poly-crystalline, and thin film. Finally, to check the feasibility of the proposed technique, this paper compares the approximate parameters of modeled I-V curves with experimental curves. The findings confirm the reliability of the estimated model parameters in simulating the near realistic characteristics of the PV modules.

The 4.5 MW Cal Poly Goldtree Solar Farm is the largest solar array in the CSU system. It generates up to 25% of the university’s yearly power. However, it currently faces an issue of shading. During some mornings and evenings, solar panels will cast shade on other panels which will decimate the performance of any module that is shaded. Backtracking is a technique that combats this by sub-optimally tracking the sun until the sun is high enough in the sky so that no shade will be cast on any modules. Due to the uneven terrain of the solar farm, this is a difficult technique to perfect. The goal of this project is to investigate and identify the areas where there is significant power loss due to row-to-row shading, then adjust the current backtracking algorithm such that performance is improved.
