Industrial Photovoltaic Systems: An Economic Analysis in Non-Subsidized Electricity Markets

摘要: Photovoltaic (PV) systems are becoming a relevant electricity source, characterised by growing trend in the last years. This paper analyses economic feasibility of investments industrial PV different sizes (200 kW, 400 1 MW, and 5 MW), absence subsidies, mature market (Italy). The selected indicators for this kind assessment net present value (NPV) discounted payback time (DPBT). Furthermore, environmental advantage comparison to fossil sources energy is evaluated through reduction carbon dioxide emissions (ERcd). Finally, sensitivity analysis on critical variables (percentage self-consumed energy, average annual insolation rate, purchase price, sale unitary investment cost opportunity cost) conducted. Results highlight strategic role self-consumption an public policy incentives presence interesting opportunities applications.
