The global energy market is characterized by the strong growth of photovoltaic (PV) energy.

Abstract
The global energy market is characterized by the strong growth of photovoltaic (PV) energy. This renewable source contributes to sustainable development and is a strategic player in the electricity market. The profitability of PV systems is determined by incentive tariffs in developing markets and by the share of self-consumption in developed markets. This paper aims to evaluate (i) the profitability of PV systems in the residential sector without subsidies and (ii) the profitability of energy storage in a mature market (Italy). In this way, it is possible to define the economic results of integrated PV-battery systems, and the indicator used is the Net Present Value. Furthermore, a sensitivity analysis is conducted on the critical variables. The mathematical model proposed in this paper defines the break-even point of the increase of self-consumption at which residential PV battery systems become economically viable in a mature market. Energy storage systems are useful only when the relationship between supply and demand permits them to induce a significant increase of energy self-consumption.File | Dimensione | Formato | |
