Photovoltaic power generation is one of the cleanest sources for producing renewable energy, however to date its up take on the Irish renewable energy market has been extremely low. Through research carried out on regions where these technologies are widely used and developed, this project investigates the feasibility of using photovoltaic systems to generate power under Irish climatic conditio...
The Effect of Solar Irradiance on the Power Quality Behaviour of Grid Connected Photovoltaic Systems
Photovoltaic systems have been increasingly used in the generation of electrical energy, either as a means of providing electricity in areas where there is no grid connection (stand alone systems), or by providing electricity to the grid (grid connected systems). In a deregulated energy market, the cost of energy produced from fossil fuels is rising and the photovoltaic energy becomes a promisi...
We present a quantum formalism that provides a quantitative picture of the fundamental processes of charge separation that follow an absorption event. We apply the formalism to two-level photovoltaic cells and our purpose is to pedagogically explain the main aspects of the model. The formalism is developed in the energy domain and provides detailed knowledge about existence or absence of locali...
The electric power supplied by a photovoltaic power generation system depends on the solar radiation and temperature. Designing efficient PV systems heavily emphasizes to track the maximum power operating point. This work develops a novel three-point weight comparison method that avoids the oscillation problem of the perturbation and observation algorithm which is often employed to track the ma...
