[0002] Awnings have undergone iterative development to meet the sunshade needs of people's lives, including RVs and buildings. With the development of awning technology and the application of flexible photovoltaic modules, photovoltaic awnings, which replace the traditional retractable awning fabric with flexible photovoltaic modules, have emerged.

[0003] However, the power transmission of such photovoltaic awnings has a significant drawback: it typically requires the two-pole circuits of the photovoltaic modules to be routed through the front pole, through the curved arm, and then into the interior of the awning, finally being led out via wires to connect to an external power source or energy storage device. This lengthy and multi-node wiring method not only significantly increases installation complexity but also increases the risk of power transmission losses and line failures. Utility Model Content
