Shading refers to the reduction of sunlight reaching surfaces such as solar panels, caused by various factors. In solar thermal and photovoltaic systems, shading reduces solar irradiance, leading to energy losses. Shading can be temporary and/or location-dependent and may result from objects or particles like dust or leaves. Temporary shading can also occur during cleaning processes, while location-dependent shading might stem from trees or buildings. A site analysis prior to installing a solar system aims to minimize such causes. Shading can also apply to rooms or rooftops without photovoltaic systems and can involve artificial devices like blinds. In these cases, the effects are generally positive: Proper shading can significantly enhance thermal comfort in buildings. It reduces cooling demands, although in winter, natural shading can increase heating requirements.
In the context of a building's energy management, shading can have various effects. To improve energy efficiency and enhance user comfort, intelligent building automation is essential. A shading system adjusted for seasonal and daily variations plays a critical role in reducing a building's energy demand. With aedifion’s AI-driven solutions, these systems can be optimized for maximum efficiency and comfort.
