[0002] Photovoltaic curtain walls are a new type of building energy-saving technology that combines photovoltaic power generation technology with building curtain walls. This technology integrates photovoltaic power generation technology into the traditional decorative and protective functions of curtain walls, providing important support for achieving zero-carbon goals in the building sector.

[0003] The photovoltaic (PV) curtain wall market has enormous potential, especially in high-rise and commercial / industrial buildings in large and medium-sized cities. These buildings have large facade areas, providing a natural advantage for installing PV curtain walls. PV curtain walls not only meet the building's electricity needs but also enhance its aesthetics and technological appeal.

However, existing PV curtain wall technology cannot easily ventilate the interior during use, and the lifespan of the PV panels may not be synchronized with the lifespan of the building. This means that PV panels may need to be replaced during the building's lifespan, but the replacement process for existing PV curtain wall technology is relatively complex. Utility Model Content
