Do photovoltaic curtain walls improve the cost-effectiveness ratio?

After sensitivity analysis of the cost of photovoltaic curtain walls and the efficiency of solar panels, it was found that as the cost increases, the economy of photovoltaic curtain walls gradually deteriorates, and improving the efficiency of solar panels can improve the cost-effectiveness ratio of each facade.

Do VPV curtain walls save energy?

According to the literature review, VPV curtain walls exhibit significant potential for energy savings owing to their excellent thermal insulation performance . Furthermore, the shading effect of PV cells can alleviate discomfort glare and enhance occupants’ visual comfort .

Are vacuum integrated photovoltaic curtain walls performance-driven?

The vacuum integrated photovoltaic (VPV) curtain wall has garnered widespread attention from scholars owing to its remarkable thermal insulation performance and power generation ability. However, there is a lack of in-depth, performance-driven optimal design that considers the mutually constraining functions of the VPV curtain wall.

Can photovoltaic curtain wall array be used in building complexes?

Xiong et al. [ 31] develops a power model for Photovoltaic Curtain Wall Array (PVCWA) systems in building complexes and identifies optimal configurations for mitigating shading effects, providing valuable insights for the application of PVCWA systems in buildings.

What is photovoltaic technology based on exterior walls?

Photovoltaic technology has the capability to generate cleaner and low-carbon energy [ 25 ]. The photovoltaic technology based on exterior walls improves the energy performance of buildings by converting solar energy into electricity, achieving dual functional integration of solar power generation and building curtain walls [ 26 ].

What are some examples of photovoltaic curtain walls?

Examples include colored solar panels in Denmark [ 27 ], Building-integrated Photovoltaics (BIPV) walls in Italy [ 28 ], and the Ekoviikki Sustainable City Project in Finland [ 29 ]. Currently, research on photovoltaic curtain walls is still in its early stages, primarily centered around the performance evaluation of such systems.
