“…This range is lower than minimal value proposed in Table 2 concerning Italy (0.15 €/kWh) and is similar to one calculated for OECD countries (0.09 €/kWh). In according to existing literature, the reduction of PV investment costs has pushed this technology towards greater competitiveness [21,24]. A comparison with values of other technologies proposed in Table 2 confirms this evaluation. A useful tool is represented by the analysis of the distribution of discounted cash inflows (Table 8) and discounted cash outflows (Table 9).…”

“…A review on the various PV incentive systems has defined an average NPV equal to 9570 €/inhabitant under a feed-in premium tariff in 2012, 5906 €/inhabitant under an all-inclusive feed-in tariff in 2013, 2065 €/inhabitant under a 50% tax deduction in 2013 and 2380 €/inhabitant under both 50% tax deduction in 2014 with a reduction of investment costs [40]. Also, DPBT proposes interesting values with existing literature: 3-12 years [12], 4-8 years [41] and 7-15 years [21]. The case studies proposed in this work show that the profitability can reach very interesting values and consumers also play a key-role.…”

“…NPV, DPBT, Internal Rate of Return (IRR), Benefit to Cost Ratio (B/C) and LCOE are the indicators typically used in the PV context [21]. NPV and DPBT are basically used to evaluate residential PV systems [18], IRR can cause conflicting answers (multiple IRR can occur) when compared to NPV in mutually exclusive investments [22], B/C permits to translate environmental impacts in economic terms [23] and LCOE is typically used to compare the cost of the energy obtained from different sources [24].…”

Economic Analysis of a Photovoltaic System: A Resource for Residential Households

New installed annual solar photovoltaic (PV) capacity was equal to 76.1 GW in 2016 (+49%), reaching the total of 305 GW around the world. PV sources are able to achieve a greater energy independence, to tackle the climate change and to promote economic opportunities. This work proposes an economic analysis based on well-known indicators: Net Present Value (NPV), Discounted Payback Time (DPBT) and Levelized Cost of Electricity (LCOE). Several case studies are evaluated for residential households. They are based on three critical variables: plant size (1, 2, 3, 4, 5 and 6 kW), levels of insolation (1350, 1450 and 1550 kWh/(m 2 ×y)) and share of self-consumption (30%, 40% and 50%). The profitability is verified in all case studies examined in this work. The role of self-consumption, that is the harmonization between demanded and produced energy, is strategic in a mature market to improve financial performance. A sensitivity analysis, based on both electricity purchase and sales prices (critical variables), confirms these positive results. The Reduction in the Emissions of Carbon Dioxide (ER cd ) signifies an environmental improvement when a PV system is used as an alternative to a mix of fossil fuels. Finally, a policy proposal is examined based on a fiscal deduction of 50% fixing the period of deduction equal to 5 years.

“…The LCOE calculation method is internationally recognized as a benchmark for assessing the economic viability of different generation technologies as well as of individual projects and enables the comparison of different energy technologies with respect to their costs. [24][25][26][27][28] Besides, the LCOE method is able to reflect the key factors of the production cost throughout the lifetime of the power plant in just one number and it causes a great reduction in complexity and allows a quick and easy comparison of different alternatives. 29,30 According to Myhr et al, 31 from an economic point of view, the LCOE contains the most important factors contributing to the economic evaluation of a project.…”

To promote a low‐carbon society, it is urgent to better integrate renewable energies into energy supply systems. This paper examines the impact of solar photovoltaic (PV) integration into the national electrical grid in Burkina Faso on the electricity production cost. The analysis is based on the levelized cost of electricity (LCOE) technique. Several levels of PV integration have been considered namely 20%, 40%, 60%, and 80% of the total installed capacity. First, the results revealed all the configurations with PV integration are more attractive and cost‐effective compared with the conventional diesel standalone electricity system. The sensitivity analysis shows that the configuration with 80% PV is the most attractive when compared to the other ones as it has the lowest LCOE and CO2 emissions compared with the other scenarios. This paper also shows that in the context of rising fuel prices and environmental concern, the electricity production based on diesel standalone system is not a viable solution for Burkina Faso at the moment. Finally, the results revealed that subsidies offered by the government of Burkina Faso to support the electricity production cost will be more effective for a system with PV integration. This paper gives detail highlights of solution for policymakers to make useful investment in solar energy and widen the access to electricity in Burkina Faso.

“…Based on the unacceptable cost of replacing or repairing the broken equipment at that time, many PV systems were turn off after a few years. The producers also had no motivation to spend their resources to maintain their systems [81]. As a result, the installation of PV plants in Italy was unregulated until 2006.…”

Abstract:Installing sustainable and renewable energy systems is a promising way of relieving Hong Kong's dependence on imported fossil fuels. Solar photovoltaic (PV) technology is a perfect solution for Hong Kong as it fits the economic and geographic situation. Through a review of the PV development history of five leading PV countries, Germany, Japan, Italy, Mainland China, and the USA, this paper serves as a useful policy toolbox to aid PV development. Based on the forerunners' successful PV industry experiences and Hong Kong's unique local situations, a series of incentive strategies were proposed for Hong Kong to help promote the utilization of solar PV systems by reducing the initial investment and providing reasonable subsidies at the initial stages and during the operation period of the PV systems. These results could be a practical reference for promoting renewable energy applications for local policy-makers.
