“…Photovoltaic adoption requires high technical standards [87]. Although Brazil stands out in terms of solar radiation [9], the largest markets for photovoltaic systems are China, Germany, Italy, and the United States, which have greater technical maturity [88]. The quality of photovoltaic systems is fundamental for the adoption of this technology [61] because its efficiency is directly linked to the economy that the individual will have by adopting it since more efficient equipment ensures a higher generation of electric power [107].…”

“…In this way, solar energy stands out in the transition from non-renewable electricity generation to renewable energy, especially regarding the distributed generation. Among the countries with the highest generation capacity, Brazil stands out in solar energy due to its large geographical area with favorable conditions and high irradiation rates [9]. Furthermore, the photovoltaic generation has a highly competitive potential within the energy scenario [10].…”

The diffusion of photovoltaic distributed generation is relevant for addressing the political, economic, and environmental issues in the electricity sector. However, the proliferation of distributed generation brings new administrative and operational challenges for the sustainability of electric power utilities. Electricity distributors operate in economies of scale, and the high photovoltaic penetration means that these companies have economic and financial impacts, in addition to influencing the migration of other consumers. Thus, this paper aims to systematically identify and evaluate critical factors and indicators that may influence electricity distributors in predicting their consumers' adoption of photovoltaic technology, which were subjected to the analysis of 20 industry experts. Results show that the cost of electricity, generation capacity, and cost of the photovoltaic systems are the most relevant indicators, and it is possible to measure a considerable part of them using the internal data of the electricity distributors. The study contributes to the understanding of the critical factors for the forecast of the adoption of consumers to distributed photovoltaic generation, to assist the distribution network operators in the decision making, and the distribution sustainability. Also, it establishes the theoretical, political, and practical implications for the Brazilian scenario and developing countries.

“…In recent years, several methods of estimating PV energy performance have been proposed, which include process-chain analysis, standard parameters, system dynamics model, Balance Scorecard, spatial planning, and performance simulation [1][2][3][4][5][6]. These methods consider different PV technological features together with the actual characteristics of the operating settings.…”

Environmental Efficiency of Photovoltaic Power Plants in China—A Comparative Study of Different Economic Zones and Plant Types

et al. 2018

In this paper we study and compare the environmental efficiency of 118 photovoltaic (PV) plants in China. Drawing on the nonparametric data envelopment analysis (DEA) method, our study takes the initiative to take the insolation, annual sunshine duration, and covering area as input variables into account, as well as the installed capacity, annual electricity generation, CO2 emission reduction, and coal saving as output variables, to provide a unified measure of environmental efficiency of PV plants in China. We find widespread inefficiencies in roughly 95% of the PV plants, and the performance of different economic zones and types of PV plants are quite different. Specifically, those PV plants in eastern China are the least satisfying performers among three different economic zones. The surprising result indicates that eastern China has room for improvement by overcoming the inefficiencies caused by serious aerosol pollution and the high urbanization rate. We also find rooftop PV plants have the highest efficiencies among the four types of PV plants due to very little power loss. However, complementary PV plants have the lowest efficiencies most likely because of high operating temperatures during the process of power generation.

“…To better forecast the energy production, it is necessary to have a good model for the module. Some methods of energy estimation have been used to forecast the generated energy in specific conditions, de Azevedo Dias et al [2]. Loschi et al (2015) [3] presents a solar tracker method review as well as the energy estimation method review.…”

Photovoltaic modules (PV) are tested in the industry in standard conditions and their characteristics are given in the datasheet. After installation on the site, its performance is not evaluated separately of the other parts of the PV generator. Nevertheless some discrepancies of the expected generation and the measured ones are verified. To deal with these discrepancies it is worth characterizing the module on the site and acquire data in an easy and inexpensive way. This paper presents a proposed characterization system as well as its application. A module test was performed on a site located in Brazil. At these latitudes it is common to have high amount of ultraviolet components. The characterization system measures separately the ultraviolet component, as well as the visible and global irradiations. The results obtained are analyzed and the effect of the UV variation is observed, proving the importance of doing this characterization on site after implementation of the PV system.
