Analysis of shading and energy generation by PV overhang using different models
Abstract: This paper presents the shading and energy generated by photovoltaic integrated overhangs in a building. The air temperature is greatly raised by sunlight entering through glass facades and windows that are not shaded. The overhang decreases the sunlit area of the windows thus decreasing the inside room temperature which decreases the requirement of cooling the rooms. The energy production by the photovoltaic modules has been calculated using three popular energy …
