AI Technical Summary
In existing technologies, photovoltaic panels and building exterior wall insulation measures have not been effectively integrated in new construction and renovation of old walls, resulting in resource waste and increased construction complexity.
The system adopts an attached solar photovoltaic wall structure, which combines the photovoltaic panels with the building wall through a keel system to form a closed insulation cavity. It also utilizes a non-removable template to achieve flexible installation of the photovoltaic panels and concealed wiring.
It achieves a unified solution for photovoltaic power generation and building insulation, applicable to both new and existing buildings, reducing construction complexity and costs, improving aesthetics, and enhancing building energy efficiency.
