Abstract(s)
Este trabalho visa analisar a possibilidade de um aumento da capacidade da Unidade de Produção em Autoconsumo da Lidergraf, SA. A empresa, que já tem uma Unidade de Produção de Autoconsumo em funcionamento de 750 kWp, que lhe permite uma autossuficiência anual de aproximadamente 18%, mas tem a intenção de a ampliar,
aproveitando espaço existente e a oportunidade legislativa. Foi realizado um dimensionamento da Unidade de Produção em Autoconsumo de forma a chegar a pelo menos 50% de autossuficiência com o recurso a ferramentas informáticas como PVSyst e Helioscope. Determinou-se que seria necessário acrescentar 1 148,85 kWp à instalação existente e desenhou-se a implementação dos módulos fotovoltaicos no terreno disponível. Serão necessários acrescentar 2070 módulos fotovoltaicos, distribuídos por mesas solares estacadas em terreno, e conectados a 9 inversores de corrente. Após o contacto a diferentes fornecedores e instaladores certificados, foi possível determinar um valor aproximado de investimento inicial de 676 000,00 €.
Convertendo o valor de produção de energia anual, tendo em conta a perda de rendimento dos módulos, foi possível concluir que o prazo do retorno do investimento será de 4,19 anos. O período de vida para a instalação foi de 30 anos e o investimento é recomendável.
This work aims to analyse the possibility of increasing the capacity of Lidergraf, SA's self-consumption production unit. The company already has a 750 kWp self-consumption production unit in operation, which gives it an annual self-sufficiency of approximately 18%, but it intends to expand it, taking advantage of existing space and legislative opportunities. The self-consumption production unit was dimensioned to achieve at least 50 per cent self-sufficiency using computer tools such as PVSyst and Helioscope. It was determined that 1,148.85 kWp would need to be added to the existing installation and the implementation of the photovoltaic modules on the available land was designed. It will be necessary to add 2070 photovoltaic modules, distributed over solar tables staked on the land and connected to 9 current inverters. After contacting different suppliers and certified installers, it was possible to determine an approximate initial investment value of €676,000.00. Converting the estimated annual production value, taking into account the loss of performance of the modules over time, it was possible to conclude that the payback period will be 4.19 years. As we are talking about a photovoltaic installation with a lifespan of approximately 30 years, the investment is profitable.
