“…For this reason, policies that encourage this type of power generation could also help to increase the production of photovoltaic modules (today the vast majority are imported from other countries) and, consequently, decreasing installation costs, as well as generating return for Brazilian economy. Loan and financing programs in banks such as Caixa Econômica Federal (Caixa), The Brazilian Development Bank (BNDES) and Santander are found in Brazil today, although they do not have wide dissemination and solid projects for large-scale implementation of solar energy (Garcia, Nogueira, & Betini, 2018).…”

Purpose: This paper presents a systematic literature review regarding economic feasibility studies and photovoltaic solar energy production. Methodology/Approach: To this end, publications from 2015 to 2019 were collected in two journal databases: Web of Science and Science Direct. In order to create a corpus more relevant to the aim of this research, a selection among the papers found was made respecting some established filters. Subsequently this refinement, the resulting corpus consisted of seventeen papers. Findings: A current matter discussed by the researchers was identified, regarding the study on the best photovoltaic system to be used for each user: whether batteries are the best option as a storage source, or the connection of the system to the network is the most adequate guarantee to meet demand. Research Limitation/implication: This review gives the present study a characteristic of bringing together what, within the mentioned period and in the searched bases, has been approached in different works that deal with the economic feasibility analysis regarding the photovoltaic solar energy production. Originality/Value of paper: can support the implementation of solar systems in peripheral locations where the technology is still little used.

Analysis of Scenarios for the Insertion of Electric Vehicles in Conjunction with a Solar Carport in the City of Curitiba, Paraná—Brazil

The growing environmental impact and rising emission of greenhouse gases have accelerated the research toward renewable energy sources and electric vehicles since one of the main sources of pollution is the CO2 emissions produced by conventional combustion vehicles. This article presents the analysis of the energy balance between a photovoltaic carport with 4.89 kWp installed capacity and an EV, model Renault Fluence ZE DYN, driven in real conditions. The driving tests were performed during the winter season in the city of Curitiba, the capital of the state of Paraná, Brazil, with approximately 1.7 million inhabitants and 1.1 million vehicles. During the test period, we attempt to reproduce the citizen’s daily routes through the city, presenting an average consumption of 15.75 kWh/100 km. The carport PV module’s energy generation and in-plane incident irradiation were acquired to calculate the performance ratio, making a comparison after cleaning maintenance possible. The solar carport system has 4.89 kWp and has generated an average of 465.37 kWh during its 24 months of operation. The analysis scenarios consist of replacing part of the city’s combustion vehicle fleet with the EVs (the same as used in the study) and thus determining how many replicas of the presented photovoltaic systems might be needed, as well as the area required for the installations. In a simulation with 15% of the fleet’s replacement, it would be necessary to generate 17,151.8 MWh, which requires the construction of 36,856 carports, covering an area of approximately 1,105,685 m². Finally, an economic comparison between an internal combustion vehicle and the EV determined that the expenditures involving electric energy to charge the batteries are 3.3 times lower than buying gasoline, assuming the same driving routines.

“…For the authors, when modifying the financing mode by increasing or reducing the use of equity, the greater the initial investment cost in the zero year, the longer the return on investment. For Garcia et al [82], the existence of financing programs, for those interested in buying their own microgeneration centers, would be of great importance. The creation of a national program aimed at introducing PV energy not only for residential use, but also for companies, would bring prosperity to the country.…”

Identification and Analysis of Impact Factors on the Economic Feasibility of Photovoltaic Energy Investments

et al. 2020

The introduction of environmental impact targets around the world has highlighted the need to adopt alternative sources of energy, which can supply the demand and mitigate the damage caused to the environment. Solar energy is one of the main sources of alternative energy, and is considered an abundant source of clean energy. However, to facilitate and encourage investors interested in the installation of photovoltaic energy systems for electricity production, it is essential to evaluate the factors that impact the economic viability of the projects. Therefore, the objective of this research is to present a systematic analytical framework, in order to identify and analyze the main factors that impact the financial feasibility of projects for the installation of photovoltaic energy plants. For this purpose, a systematic literature review was carried out, analyzing the main studies related to the topic and identifying the main factors that may financially affect investments in photovoltaic energy systems. From this review, 29 influencing factors were identified and separated into five categories, namely, location, economic, political, climatic and environmental, and technical factors. The main factors highlighted are the investment cost, power generation, operation and maintenance costs, solar radiation, lifetime, energy tariff, efficiency, electricity consumption, and interest and taxes. The results may assist policy makers, investors, researchers, and other stakeholders to identify the key factors that are being examined in the literature, and to evaluate which ones should be considered in their study to ensure the sustainable development of power generation through the solar source.
