When modeling photovoltaic (PV) systems, accuracy of panel parameters is of great importance. In this study, a system which aims to determine the parameters of PV panels by experimental way has been developed. The characteristic curves of the FV panels are sampled with the proposed system and transferred to the developed MATLAB software. In the MATLAB software, Newton Raphson, Secant, Bisection and Regula Falsi methods are applied for parameter determination. It has been observed that Secant method is the fastest method, besides all root detection methods used to determine parameters with high success.

Fotovoltaik (FV) sistemlerin modellenmesinde panel parametrelerin doğruluğu büyük önem teşkil etmektedir. Bu çalışmada, FV panellerin parametrelerinin deneysel yolla belirlenmesini hedefleyen bir sistem geliştirilmiştir. FV panellerin karakteristik eğrileri önerilen sistem ile örneklenmiş ve geliştirilen MATLAB yazılımına aktarılmıştır. MATLAB yazılımda, parametre tespiti için Newton Raphson, Secant, Bisection ve Regula Falsi yöntemleri uygulanmıştır. Kullanılan tüm kök bulma yöntemlerinin yüksek başarıyla parametre tespiti yapmasının yanında Secant yönteminin en hızlı yöntem olduğu gözlemlenmiştir.
