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.
What is a photovoltaic curtain wall?
A photovoltaic curtain wall has the added benefit ofgenerating electricity over the building’s life. Whilst it costs a bit more than standard curtain walling, the incremental cost of a BIPV facade will typically be paid back within around five years. The standard material for a photovoltaic facade is thin film glass (see picture below).
How much power does a photovoltaic curtain wall generate?
Based on Table 7 and Table 8, the annual and total power generation data for the photovoltaic curtain walls on different facades can be obtained. The south facade’s photovoltaic curtain wall has the highest power generation capacity, with a cumulative power generation of 17,730.42 MWh over a 25-year period.
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 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%.
What are the benefits of a photovoltaic curtain wall?
It also improves the aesthetic appearance of the building. A photovoltaic curtain wall has the added benefit ofgenerating electricity over the building’s life. Whilst it costs a bit more than standard curtain walling, the incremental cost of a BIPV facade will typically be paid back within around five years.
