摘要

In this paper, the interrelationship between the excess energy in a photovoltaic system with battery storage (when the battery is fully charged) and the excess energy if there is no storage is presented. The graphic relationship of those two characteristic energies is obtained by the computer simulation using the hourly measured values of solar irradiation (global and diffuse) incident on a horizontal plane as input data base. The energy flow through the photovoltaic system is determined as time-integrated value of power being produced during each hour. The energy balance model, which governs the behaviour of the different components (array, battery and load), is obtained by considering the energy flow at each component of the system separately.
