▎ 摘　　要

NOVELTY - The device has a photovoltaic generating set (1) provided with a water inlet pipe seat (6). An inner side of a rear mounting frame (4) is provided with an outer drain pipe (7). An end of an external drain pipe is connected with a storage water tank (8). A bottom end of the storage water tank is connected to a water outlet pipe. A water collecting main control unit (9) is arranged on a side of the water outlet pipe away from the storage water tank. An outer row pipe head (10) is installed on an outer row of the water collecting main control unit away from the water outlet pipe. USE - Solar photovoltaic power generation using device. ADVANTAGE - The device utilizes graphene high efficient heat-conducting ability to realize high speed heat exchange, thus preventing hot water from flowing reversely, and hence improving power generation efficiency and battery storage efficiency of the device. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a solar photovoltaic power generation using method. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a Solar photovoltaic power generation using device.
