Technical FAQs 4

What is bifacial photovoltaic shading?

The buildings with high wall reflectivity and low WWR achieve more energy savings. Solar photovoltaic (PV) shading systems are of great significance for achieving low-carbon buildings. Bifacial photovoltaics (bPV) is a promising technology that can generate electricity from both the front and rear sides of bPV modules.

Can bifacial photovoltaics be used as sunshades?

This paper integrates bifacial photovoltaics as sunshades into buildings. The impact of installation and building factors on power generation is studied. The impact of installation factors of bPV on the energy savings is studied. The south orientation, small tilt angle and wide bPV are recommended to install.

Do sunshades increase energy consumption?

However, it is noted that the introduction of sunshades can lead to an increase in artificial lighting usage. In hot and humid climates, the overall energy consumption of a building is primarily attributed to the energy required for cooling and lighting.

Can BPV sunshades save energy?

Building energy savings Apart from electricity generation, another crucial function of building-integrated bPV sunshades technology is to mitigate cooling energy consumption. However, it is noted that the introduction of sunshades can lead to an increase in artificial lighting usage.
