Resumo
Este estudo teve o intuito de verificar a viabilidade econômica e financeira da
instalação de um sistema de geração de energia fotovoltaica para suprir a
demanda de energia do sistema de climatização da empresa Kaisen Car Center.
Para isso, revisou-se o projeto de climatização da empresa e determinou-se o
consumo mensal médio de energia do sistema utilizando dados técnicos
fornecidos pelos fabricantes e pelo INMETRO. Após este cálculo, verificou-se os
custos anuais com energia elétrica do sistema de ar condicionado com base nos
cálculos de consumo já realizados e a tabela de tarifa da concessionaria de
energia CEEE Grupo Equatorial. Com base nos dados de consumo do sistema
de climatização, já calculados, dimensionou-se o sistema de energia solar
fotovoltaico necessário pra suprir a demanda de energia deste sistema. Os
resultados mostraram que serão necessários 47 módulos fotovoltaicos modelo
JAM72S20455/MR da marca JA Solar e um inversor modelo MID15KTL3-X da
fabricante Growatt. Com o sistema dimensionado foi orçado o custo de compra
e instalação deste sistema fotovoltaico com a empresa Solaxis Engenharia, onde
o valor do orçamento foi de R$ 89.139,99. Com o base nos dados de consumo
de energia, estimou-se a economia com energia elétrica acumulada, no período
de análise, com a instalação do sistema de energia solar fotovoltaica na
empresa. Para isso somou-se os valores de economia com energia elétrica
anuais durante o período de análise de 25 anos onde este valor chegou a R$
1.818.218,80 no final do período. A análise econômica e financeira do projeto,
utilizando os dados já calculados, mostrou que o retorno financeiro ao final do
período de análise foi de R$ 1.729.078,81 e o tempo de retorno do investimento
foi calculado em aproximadamente 3 anos e meio verificando-se que é viável o
projeto em análise.
This study aimed to verify the economic and financial viability of installing a photovoltaic energy generation system to supply the energy demand of the air conditioning system of the company Kaisen Car Center. For this, the company's HVAC project was reviewed and the average monthly energy consumption of the system was determined using technical data provided by the manufacturers and by INMETRO. After this calculation, the annual costs of electricity for the air conditioning system were verified based on the consumption calculations already carried out and the tariff table of the energy concessionaire CEEE Grupo Equatorial. Based on the already calculated consumption data of the air conditioning system, the photovoltaic solar energy system needed to supply the energy demand of this system was dimensioned. The results showed that 47 photovoltaic modules model JAM72S20455/MR from the brand JA Solar and an inverter model MID15KTL3-X from the manufacturer Growatt will be required. With the dimensioned system, the cost of purchase and installation of this photovoltaic system was budgeted with the company Solaxis Engenharia, where the budget value was R$ 89,139.99. Based on energy consumption data, savings with accumulated electricity were estimated, in the analysis period, with the installation of a photovoltaic solar energy system in the company. For this, the annual electricity savings values were added during the 25-year period of analysis, where this value reached R$ 1,818,218.80 at the end of the period. The economic and financial analysis of the project, using the data already calculated, showed that the financial return at the end of the analysis period was R$ 1,729,078.81 and the return-on-investment time was calculated in approximately 3 and a half years, verifying that the project under analysis is viable.
