“…The useful lifetime of the investment project is 20 years, and this value is equal to the lifetime of a PV plant. A review on this last topic defines as solar PV gets a 20 to 25 years lifespan [34] and the scenario with a time duration of 20 years is basically less profitable than one in 25 years when considering the low operative cost [35,36]. The choice of 20 years is considered more suitable in several works [3,37,38].…”

The Economic Feasibility of Residential Energy Storage Combined with PV Panels: The Role of Subsidies in Italy

2017

A solar photovoltaic system produces electricity by converting energy from the sun. By the end of 2016, the global installed solar photovoltaic capacity reached 305 GW. Its growth is impressive in the last years; in fact, it was only equal to 41 GW in 2010. However, Europe has installed only 6.9 GW in 2016 (−1.7 GW in comparison to previous year) and this annual power installed is equal to 9% of global one in according to data released by Solar Power Europe. The profitability of PV systems in mature markets depends on the harmonization between demanded energy and produced one residential energy storage when combined with photovoltaic panels is able to increase the share of self-consumption. This work proposes a mathematical model, in which a Discounted Cash Flow analysis is conducted to evaluate the financial feasibility of photovoltaic-integrated lead acid battery systems in Italy. The indicator used is Net Present Value. Furthermore, a break-even point analysis, in terms of an increase of self-consumption, is conducted. The residential sector is investigated and energy storage system investment is incentivized by fiscal deduction and regional subsidies. The analysis provides several case studies, determined by combinations of the following variables: photovoltaic plant size, battery capacity, the increase of the share of self-consumption, and the useful lifetime of energy storage system. The same case studies are proposed also in four alternative scenarios, where is the modified the structure of subsidies. Results confirm that the profitability can be reached in presence of subsidies.

“…This limit can be addressed by implementing a sensitivity analysis on critical variables [43]. In this sense, such an analysis is able to define dynamic scenarios, in line with similar studies [13,24]. The assessment can be done by considering different plant dimensions, such as 200 kW (Figure 2 ‚ Percentage of self-consumed energy (ω self,c ), assesses the level of harmonization between consumption and production of energy.…”

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

2015

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

“…Climate change, the Kyoto Protocol, and the need to reduce energy costs are obliging industries to rapidly acquire knowledge of energy options in key sectors [1], such as the agri-food sector. For example, photovoltaic (PV) energy is one of the renewable energy sources that is widely used in the agricultural sector for various activities [2,3], such as water pumping systems for irrigation, or electricity generation [4][5][6]. Nevertheless, to date, it has not been widely used in wine production.…”

Economic and Environmental Study of Wineries Powered by Grid-Connected Photovoltaic Systems in Spain

This research developed a system that can make factories more independent from the grid. The system enhances efficiency since factory operation is powered by the renewable energy generated during the production process. Winemaking is a key sector that can profit from such a system because wineries can recycle much of the waste from the raw materials employed in wine production. Moreover, the solar energy collected at winemaking facilities can also be used to reduce electricity consumption and thus increase energy efficiency. This study investigated the feasibility of using renewable energy sources, such as solar energy, in wineries in Spain, given the quantity of renewable energy produced in the country. For this purpose, cost-effectiveness, power generation, CO 2 emissions and the renewable energy fraction were taken into account. The assumption was that the photovoltaic system was grid-connected. Research results showed a reduction in electrical power costs ranging from 4% to 36%. This reduction was accompanied by an increase in the use of renewable energy of up to 57%. The results obtained are based on self-consumption or net metering policy as well as the production capacity of the winery.
