Abstract(s)
A dissertação apresentada enquadra-se no âmbito da eficiência energética. Neste trabalho foram estudadas as componentes técnicas e económicas de uma central fotovoltaica para autoconsumo e melhoria de uma ferramenta informática previamente projetada em linguagem VBA. Esta ferramenta foi projetada em ambiente empresarial com o intuito de auxiliar uma empresa de engenharia na área da energia a reforçar a sua posição no mercado das energias renováveis, mais concretamente em projetos de sistemas fotovoltaicos. A ferramenta poderá ser utilizada como suporte para empresas ESCO, elaborando relatórios que servem de base para contratos de performance ou apenas para a apresentação de propostas para uma venda direta a um cliente. De modo a facilitar um processo de dimensionamento fotovoltaico, que é algo complexo e moroso, esta dissertação tem como principal objetivo criar uma ferramenta que facilite este processo. Esta será capaz do carregamento das várias variáveis técnicas e financeiras e otimizar o dimensionamento da central. Foram realizados testes à ferramenta com dados reais, e conclui-se uma mais-valia em relação a um método de dimensionamento manual. Das vantagens de utilização da ferramenta pode-se destacar a capacidade de otimização do número de módulos numa dada instalação, a facilidade com que se define um tempo de contrato, assim como a capacidade de monitorizar a produção da central ao longo dos anos de contrato.
The thesis presented here is framed in the study of energy efficiency. In this work, it was studied the economic and technical components of photovoltaic panels for self-consumption and an improvement of an informatic tool previous designed in VBA language. This tool was designed in workplace environment with the purpose of helping an engineering company strengths its position on the renewable energy market, especially in photovoltaic plants. This tool can be used to help ESCO company’s elaborating reports that serve for energy performance contracts or just direct offers to a client. Photovoltaic dimensioning is a complex and time-consuming process, so in a way to facilitate this process this thesis has its main objective to create an informatic tool. With access to the load diagram of a facility and the local radiance it will be able to make technical and economic reports using as method of calculus the optimization of photovoltaic panels for each specific case. The tool was subject of tests with real data and it was concluded it was an advantage comparing with the manual dimensioning. Of its advantages, the capacity of optimization of photovoltaic plants as well as its capacity of monitoring the production were the most valuables.
