    Na busca pela sustentabilidade no setor energético, a energia solar fotovoltaica (FV) vem-se destacando como solução para promover o desenvolvimento sustentável. À medida que a tecnologia FV se expande, surge a necessidade de estudos para a avaliação de como o novo mercado se comporta diante de diferentes cenários, com a consequente elaboração de indicadores diversos. Seguindo uma abordagem interdisciplinar e baseado no paradigma epistemológico da Design Science, o objetivo do presente estudo foi analisar, após seleção e avaliação, indicadores que reflitam um possível impacto da pandemia de COVID-19 no mercado de Micro e Minigeração Distribuída Fotovoltaica no Brasil (MMGD) nos anos de 2020 e 2021. Para tanto, caracterizou-se, por meio de revisão sistemática da literatura (RSL), o estado da arte a respeito do impacto da pandemia de COVID-19 no mercado fotovoltaico e de indicadores aplicados a sistemas fotovoltaicos. Com subsídios da RSL e conforme a literatura de base sobre o assunto, selecionou-se o indicador Potência Mensal Instalada de sistemas fotovoltaicos. Efetuou-se então a análise deste por meio de alimentação do indicador, por meio de consulta em banco de dados abertos da Agência Nacional de Energia Elétrica (ANEEL). Identificou-se que, com a sensibilização geral inicial causada pelo primeiro pico da pandemia de COVID-19, o mercado fotovoltaico sofreu redução na Potência Mensal Instalada; porém, passado esse momento inicial, observou-se a recuperação do indicador, o que sugere capacidade de resiliência e de adaptação desse mercado, superando as dificuldades e novos desafios encontrados e mantendo o ritmo de crescimento observado antes da pandemia.In the search for sustainability in the energy sector, photovoltaic solar energy (PV) has been highlighted as a solution to promote sustainable development. As PV technology expands, there is a need for studies to assess how the new market behaves in different scenarios with the consequent elaboration of different indicators. Following an interdisciplinary approach, and based on the epistemological paradigm of Design Science, the objective of this study was to analyse, preceded by selection and evaluation, indicators that reflect a possible impact of the COVID-19 pandemic on the Micro and Mini Photovoltaic Distributed Generation (MMDG) market in Brazil in 2020 and 2021. To do so, it was characterized through a systematic literature review - SLR, the state of the art about impact of the COVID-19 pandemic on the photovoltaic market and photovoltaic systems indicators. Subsidized by RSL and supported by the core literature on the subject, the Photovoltaic Systems Monthly Installed Power Capacity indicator was selected. Then, the analysis of this was carried out, by means of feeding the indicator using a query in the open database of the brazilian National Electric Energy Agency - ANEEL. It was identified that with the initial general awareness, caused by the first peak of the COVID-19 pandemic, the photovoltaic market suffered a reduction in the Monthly Installed Power Capacity, however, after this initial moment, the indicator recovered, suggesting a capacity for resilience and adaptation of this market, overcoming the difficulties and new challenges encountered, maintaining the pace of growth observed before the pandemic

    ABSTRACT This work presents the mapping of grid-connected photovoltaic systems supported by the Normative Resolution (NR) of the National Agency of Electric Energy (ANEEL) N¬ļ 482/2012 in the city of Curitiba. Firstly, a brief introduction was made justifying the reasons that led to the development of this study, followed by the explanation about the methodology, procedures and criteria adopted in the study. A general mapping of all on-grid photovoltaic systems supported by NR N¬ļ 482/2012 installed in the city of Curitiba, identified by class, is presented, indicating how the urban distribution of these photovoltaic systems occurs, and it is possible to observe in which regions the highest prevalence of installations occurs. From this, the general characterization of these photovoltaic systems is performed, classifying them by class, number of installed systems, power, number of modules, total occupied area, average power of modules and average efficiency of photovoltaic systems. Considerations are also raised regarding the reliability of the Database of Distributed Generation Consumer Units made available by ANEEL

    In the search for sustainable development, the energy issue is one of the main focuses, facing the difficulties of the paradigm of sustainable development, where it is necessary to reconcile the maintenance of the supply of energy inputs with the maintenance in the short and long term of environmental, social , ethical, cultural, economic, spatial and political needs of society. In this context, renewable sources of electricity generation are identified as a solution to promote sustainable development in the electric power generation sector. Photovoltaic generation, in turn, presents itself as an already consolidated way of implementing sustainable development in the energy sector. The unpredictability of the photovoltaic scenario, especially of micro and mini distributed generation supported by REN No. 482/2012 of ANEEL, makes difficult the elaboration of growth forecasts and consequently the planning of the sector. Thus, it is necessary to draw a panorama of how the insertion of this segment in the Brazilian territory and in several space cuts is identified, identifying the usual characteristics of these SFV and understanding how its process of dissemination and consolidation occurs in Brazil, thus making , the expansion of photovoltaic generation better understood and harnessed in its technical, urban and social aspects. The research showed the trend of increasing the participation of the centralized PV generation versus the distributed PV generation; the rapid evolution of distributed photovoltaic power installed in Brazil as well as in Paran√° and Curitiba; the typical profile of a photovoltaic system installed in different classes of consumer units; that centralized generation systems are located near the sites with the highest solar irradiance, while distributed generation systems are concentrated in large urban centers; that most of the SFVCRs of distributed generation in the state of Paran√° are located in the areas of greatest irradiation in the state; the regions with the highest power and amount of SFV per capta. Thus, this work allowed a broad understanding of different aspects of the expansion of the photovoltaic generation of micro and mini distributed generation in Brazil, the State of Paran√° and the City of Curitiba.Na conjuntura de busca pelo desenvolvimento sustent√°vel, a quest√£o energ√©tica assume um dos focos principais, enfrentando as dificuldades do paradigma do desenvolvimento sustent√°vel, onde √© necess√°rio conciliar a manuten√ß√£o do fornecimento de insumos energ√©ticos com a manuten√ß√£o no curto e longo prazo das necessidades ambientais, sociais, √©ticas, culturais, econ√īmicas, espaciais e pol√≠ticas da sociedade. Neste contexto, as fontes renov√°veis de gera√ß√£o de energia el√©trica se apresentam como uma solu√ß√£o de promover o desenvolvimento sustent√°vel no setor de gera√ß√£o de energia el√©trica. A gera√ß√£o fotovoltaica, por sua vez, se apresenta como uma j√° consolidada forma de se implementar o desenvolvimento sustent√°vel no setor energ√©tico. A imprevisibilidade do cen√°rio fotovoltaico, sobretudo de micro e minigera√ß√£o distribu√≠da amparada pela REN N¬ļ 482/2012 da ANEEL, dificulta a elabora√ß√£o de previs√Ķes de crescimento e consequentemente o planejamento do setor. Assim, faz-se necess√°rio tra√ßar um panorama de como se d√° a inser√ß√£o deste segmento no territ√≥rio brasileiro atrav√©s de diversos recortes espaciais, identificando-se as caracter√≠sticas usuais destes SFV e entendendo como ocorre o seu processo de dissemina√ß√£o e consolida√ß√£o no Brasil, tornando assim, a expans√£o da gera√ß√£o fotovoltaica melhor compreendida e aproveitada em seus aspectos t√©cnicos, urbanos e sociais. A pesquisa mostrou a tend√™ncia de aumento da participa√ß√£o da gera√ß√£o FV centralizada frente √† gera√ß√£o FV distribu√≠da; a r√°pida evolu√ß√£o da pot√™ncia fotovoltaica distribu√≠da instalada tanto no Brasil quanto no Paran√° e Curitiba; o perfil t√≠pico de um sistema fotovoltaico instalado em diferentes classes de unidades consumidoras; que os sistemas de gera√ß√£o centralizada est√£o localizados pr√≥ximos aos locais de maior irradia√ß√£o solar, ao passo que os sistemas de gera√ß√£o distribu√≠da concentram-se nos grandes centros urbanos; que grande parte dos SFVCR de gera√ß√£o distribu√≠da no estado do Paran√° est√° localizada nas √°reas de maior irradia√ß√£o do estado; as regi√Ķes com maior pot√™ncia e quantidade de SFV per capta. Assim, este trabalho permitiu compreender de forma ampla e sobre diferentes aspectos como est√° ocorrendo a expans√£o da gera√ß√£o fotovoltaica de micro e minigera√ß√£o distribu√≠da e centralizada no Brasil, no Estado do Paran√° e na Cidade de Curitiba
