In this paper modelling and simulation of photovoltaics array in local energy domain systems is presented. Photovoltaics array consists of group of connected PV modules. Thus, connected to energy domain system is building block of a photovoltaic energy conversion system. PV module is the essential power energy conversion unit of a solar energy transformation system. The output characteristics of a PV module are determined by solar irradiance, cell temperature and the output voltage of the PV module. Strong nonlinearity, in turn, enforces to use such energy system using maximum power point tracking (MPPT).
