This invention provides a strong wind-resistant double-glass photovoltaic module structure, which includes multiple photovoltaic panels. Multiple connectors are slidably connected to the bottom of each photovoltaic panel, and adjacent photovoltaic panels are staggered together via these connectors. Each photovoltaic panel has a limiting component 1 and a limiting component 2 on both sides. When the photovoltaic panels are in the unfolded state, adjacent photovoltaic panels are fixed together by the limiting components 1 and 2, achieving rapid unfolding / storage and high space-efficiency folding. Through the sliding hinge block and groove design, adjacent photovoltaic panels can be folded around an axis or slid horizontally and stacked for storage. Combined with the detachable limiting components, users can quickly lock or release the panels without tools, achieving a seamless transition from the unfolded state to the compact folded state. This greatly improves the module's space storage efficiency, facilitates transportation and storage, and supports rapid deployment and dismantling.
