Custo da Energia Solar

Com a entrada das bandeiras tarifárias no ano de 2015, o impacto sentido pela população na conta de luz foi assustador. Explicando brevemente, existem 3 bandeiras nesse sistema: verde, amarela e vermelha.
• Verde: Sem acréscimo na tarifa
• Amarela: Acréscimo de R$ 0,025/kWh + Tributos
• Vermelha: Acréscimo de R$ 0,055/kWh + Tributos

Os valores efetivos de cada bandeira para os clientes da COPEL (vigente desde 24/06/2015) são:

• Verde: R$ 0,7574/kWh
• Amarela: R$ 0,7958/kWh
• Vermelha: R$ 0,8420/kWh

Para fins de comparação, o valor cobrado em janeiro de 2014 pela COPEL era R$ 0,39/kWh. Um aumento aproximado de 115% em um período de 18 meses.
E quanto custa a energia de um sistema fotovoltaico? Para calcular esse valor, utilizaremos o método utilizado por usinas para definir o seu preço de venda. Ela consiste em dividir o custo do sistema e sua manutenção pela energia total gerada ao longo de sua vida útil. Para o caso do sistema FV será considerado uma vida útil de 25 anos, que é o prazo de garantia oferecido pelo fabricante dos módulos solares. Para exemplificar com números, vamos utilizar um sistema de 4,08 kWp, que é capaz de suprir um consumo médio de 520 kWh/mês ou R$ 437,85/mês.
Potência do sistema: 4,08 kWp
Custo do sistema: R$ 38.000,00
Manutenção acumulada em 25 anos: R$ 9.500,00 (1% a.a.)
Geração total de energia: 127.543 kWh (já considerando a depreciação do painel)

A fórmula para o cálculo é:


Ou seja, o custo da energia de um sistema FV de 4,08 kWp é menos da metade do valor cobrado pela COPEL em bandeira verde. Para as bandeiras amarela e vermelha o sistema fica ainda mais viável. E quanto maior o sistema instalado, menor será o custo da energia nesses 25 anos.
