Studies of economic viability of photovoltaic micro and minigeneration considering ANEELâs regulatory resolution number 482 / Estudos da viabilidade econÃmica da micro e minigeraÃÃo fotovoltaica à luz da resoluÃÃo normativa n 482 da ANEEL

This work consists in performing an economic study regarding the implementation of photovoltaic micro and minigeneration in the Northeast region of Brazil, considering the Compensation System for Electric Energy. A thorough literature review is presented focused on concept of solar energy, as well as potential applications and inherent advantages and disadvantages. In order do understand the current market scenario comprising photovoltaic generation in Brazil, the costs associated to several system components and involved taxes are evaluated. In order to assess solar resources in a given study region and evaluate the amount of energy that generated during one year, three examples regarding systems rated at 1.5 kW, 100 kW and 1 MW are presented and discussed. Based on key parameters such as initial investments, generation rate, operation and maintenance costs, and energy generated, the Net Present Value (NPV) and the Internal Rate of Return are calculated of each aforementioned case. It can be seen that a negative NPV is obtained for the 1.5-kW systems, while the positive values exist for the 100-kW and 1-MW ones. Besides, the Internal Rate of Return (IRR) is lower than the financial ends for the 1.5-kW system and higher for the remaining others. / O presente trabalho trata de realizar um estudo econÃmico de sistemas fotovoltaicos de micro e minigeraÃÃo para a regiÃo Nordeste do Brasil, considerando o Sistema de CompensaÃÃo de Energia ElÃtrica. Uma revisÃo literÃria aprofundada à apresentada e focada no conceito de energia solar, bem como suas potenciais aplicaÃÃes e as vantagens e desvantagens inerentes. Para entender a situaÃÃo atual do mercado com relaÃÃo à energia fotovoltaica no cenÃrio brasileiro, sÃo apresentados preÃos de aquisiÃÃo das componentes que compÃem o sistema solar e exemplificados os impostos envolvidos. A fim de mensurar o recurso solar da regiÃo de anÃlise e avaliar a quantidade de energia elÃtrica gerada em um ano, sÃo apresentados e discutidos trÃs exemplos de sistemas com as potÃncias de 1,5 kW, 100 kW e 1 MW. A partir dos dados de investimentos iniciais adotados, taxa de geraÃÃo, custos de operaÃÃo e manutenÃÃo, energia gerada sÃo calculados o Valor Presente LÃquido e a Taxa Interna de Retorno para cada sistema escolhido, tendo como resultados o VPL negativo para o sistema fotovoltaico de 1,5 kW e positivo para os sistemas de 100 kW e 1 MW, e a TIR inferior a taxa de atratividade financeira para o sistema de 1,5 kW e superior para os demais sistemas fotovoltaicos analisados.
