Abstract: The paper presents a study of the urban microclimate characteristics on the photovoltaic sources efficiency. Considering the actual interest for the renewable sources application in European Union and in the world, involving important financial efforts, the study continue with an economic component, focused to the bankability of the concrete investments projects. There are considered different photovoltaic equipments, operating in standardized and in field conditions. The conclusions are based on computer simulations and supported by measurements in the laboratory of the Hydraulic, Hydraulic Machineries and Environmental Engineering of the University Politehnica Bucharest. The results 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.
