This paper revisits classical problem of PV cell parameters extraction based only on three points of their characteristics. Given the dispersion and discrepancy of the results provided by the various extraction methods, the goal is to examine and compare some analytical methods for reconstruction of I-V curves while stressing in particular on the influence of the ideality factor on the series resistance. These methods are tested on two commercial types of PV panels: monocrystalline and polycrystalline ones. Among some results, the performed analysis has shown the profile of the series resistance with respect to the ideality factor as well as their influence on I-V characteristics. In addition, a contribution proposes an explicit expression that links the series resistance to the ideality factor derived from Cubas’ formula upon an approximation of Lambert W-function.
