These five parame-ters of PV cell/module are in fact related to two environmental parameters of solar irradiance & temperature and owing to non-linear nature of Eq. In overall, although having advantages and disadvantages, different methods have similar gaps as follows: The proposed models are not totally sufficient to study all parameters which can significantly affect to I–V and P–V characteristics of solar PV array, including physical parameters such as saturation current, ideality factor, series and shunt resistance, etc. I–V and P–V characteristics under varying irradiation with constant temperature are given in Fig. A PV module refers to a number of cells connected in series and in a PV array, modules are connected in series and in parallel. In term of two modules connected in parallel (Ns = 36, Np = 2), the value of voltage output is similar to that of it in case of one module (Ns = 36, Np = 1) but the current output doubles so the power output doubles. volume 4, Article number: 24 (2015) The I–V curve experiences multiple steps whereas the P–V curve gives many local peaks along with the maximum power point (the global peak). tracking (MPPT) techniques.
