Abstract

The increase of demand for energy, stimulated by developing countries and consequent decrease of power sources, is leading to an unsustainable future. These way renewable and clean energies are necessary to be used, particularly solar energy. It can produce heat or be directly converted into electricity, called photovoltaic (PV) energy. To achieve the grid parity the cost of components necessary to build a PV system has to decrease, specially the price of silicon. Focusing the sunlight into smaller cells, the expensive cells are substituted by cheaper elements (Concentrated Photovoltaic (CPV)). Associated to CPV there is the parabolic concentrator mirrors which are one of the vital component of many solar energy systems. The main objectives of this thesis were to study and use the optical testing tools to assist in solar concentrator development and maintenance using experimental and mathematical technique. This technique will use to measure and evaluate an optical performance of solar parabolic trough concentrator for photovoltaic system by comparing it with the ideal profile of the solar parabolic reflector. A prototype model was built to evaluate and measure the solar parabolic trough where two series of experiments is presented with different parabolic contour respectively. Before that, a mathematical formulation related with optical profile is being study to be combined and collaborated with the experimental model. The result of the measurement which is as the surface reflection angle and slope error is presented and analyzed which by then shows that a prototype model to measure a parabolic reflector which is demonstrated and analysed using mathematical modelling and experimental prototype has been achieved together with a method approach to evaluate the solar parabolic trough concentrator.
