Περίληψη

This paper presents the results of three methods that measure energy produced by photovoltaic(PV) modules integrated in various external opaque shadings of typical office buildings inGreece.These methods are related to the comparison of energy production results by three differentmodels: a simple energy computer simulation model that uses the theoretical average PVefficiency of 12%, a more complete computer simulation model using detailed equations (usingeither theoretical or real PV Market products), and real PV installations.The paper addresses the problem of designing efficient shading devices for buildings. Eachexamined method refers to a different design stage according to the level of information that isavailable to the designer. The results showed that the simple simulation and the moreelaborated models have similar performance for most of the shading devices, apart from thosewith a complicated geometry. Moreover, the complete model that uses parameters of PVmodules already available on the market can provide results of energy production even forcomplicated geometries. It is also concluded that the real PV installations produce results veryclose to the theoretical average PV efficiency of 12%.
