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.
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 .
Do VPV curtain walls block solar radiation?
In contrast, VPV curtain walls with high PV coverage may block large amounts of solar radiation entering the room, increasing energy consumption for lighting and heating. Thus, the single-objective optimal design of the VPV curtain walls is unable to balance its restrictive and even contradictory functions.
Which VPV curtain wall has the highest DGP?
It is observed that the VPV curtain wall with 10%, 0%, and 50% PV coverages of daylight, view, and spandrel sections has the highest average DGPs of 40.1%. By increasing the daylight section's PV coverage to 50%, the average DGPs decrease by 11.5%, while increasing the spandrel section's PV coverage to 90%, the DGPs only reduces by 2.5%.
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.
What is the annual power generation of photovoltaic curtain walls?
Annual power generation of photovoltaic curtain walls on different facades of buildings. According to the characteristics of photovoltaic modules, the attenuation rate of photovoltaic modules is around 2% in the first year, and the average annual attenuation rate from the following year is around 0.6%.
