Photovoltaic Sources Efficiency Evaluation in Urban Ecosystems Conditions

摘要

The paper presents a method of the photovoltaic sources efficiency evaluation considering the urban microclimate characteristics effects. In the actual context of high interest for the renewable sources application in European Union and in the world, involving important financial efforts, the cells effectiveness evaluation become important for energy systems providing design. The paper presents extended the first step of the method, the cells efficiency determination in different operation conditions. The measurements were elaborated in the laboratory of the University Politehnica Bucharest, joining a multidisciplinary team from the Physics and Hydraulics departments. Finally, the method will offer a clear picture of the real efficiency of photovoltaic equipments exploited in practical situations, and can be applied for a correct evaluation of renewable sources potential evaluation and planning.
