Does a vertically mounted bifacial photovoltaic sunshade generate electricity?

In this study, we conducted an experiment to evaluate the thermal, light, and electrical performance of a vertically mounted bifacial photovoltaic sunshade (BiPVS). Over three consecutive days, the average daily power generation was 709.4 kJ for the west-oriented PV module and 636.7 kJ for the east-oriented one.

What is a BIPV solar sunshade?

BIPV (building-integrated photovoltaic) technology can convert incident solar energy directly into electricity while reducing cooling energy consumption. Using PV modules as a sunshade also prevents glare.

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.

How does a PV sunshade affect thermal performance?

Thermal performance The thermal performance of PV sunshades refers to their ability to block a portion of the incident solar radiation on glazed window panes and affect their temperature. Additionally, the temperature of the PV sunshade itself largely influences its solar-to-electrical conversion efficiency.

What factors affect the application of PV sunshades?

The amount of power generation is a critical index for the application of PV sunshades. It is influenced by multiple factors such as the type of PV cells and their solar-to-electricity efficiency, module size and orientation, etc [ 18 ].

Can a BPV sunshade generate electricity?

The rear side of bPV sunshade can generate electricity because it can receive reflected irradiance from ground, and other surfaces . The level of irradiance received on the rear side is highly dependent on the surface properties, particularly the reflectivity of wall and window.
