Resumen La creciente demanda de energia acompanada de los elevados niveles de emision de gases contaminantes a la atmosfera hace patente la necesidad de encontrar nuevos sistemas de produccion de energia. Una de las posibles alternativas se encuentra en la energia solar de concentracion, y mas concretamente en la tecnologia termosolar con motor Stirling que alcanza unos niveles de rendimiento muy superiores a la energia solar fotovoltaica en cuanto a produccion de energia electrica. En este trabajo se muestra el diseno y la caracterizacion de un prototipo de captador paraboloidal con motor Stirling, que permite obtener datos reales del funcionamiento de este tipo de sistemas. Esto permitira modelizar de manera real el comportamiento esperado de equipos comerciales reales antes de abordar su implantacion en edificios y viviendas unifamiliares. Abstract The increasing demand for energy accompanied by high level of emission of the contaminating gases into the atmosphere underscores the need to find new energy production systems. One of the possible alternatives is concentrating solar power and, more specifically, solar thermal technology with a Stirling engine that reaches higher performance levels than photovoltaic solar energy in terms of electricity generation. This paper shows the design and characterization of a prototype paraboloidal collector with a Stirling engine that allows obtaining real data of this type of systems functioning. This will allow modelling in a real way of expected performance of real commercial devices before approaching their introduction in buildings and single-family houses.
