Abstract: A solar panel water pump assembly is provided. A solar panel apparatus includes a plurality of light-emitting diodes and is attached to a support base. The solar panel apparatus is electrically coupled to a battery cell box and a control circuit board box that are attached to a bottom side of the support base. A water conduit adapter is inserted through the solar panel apparatus and the support base via an aperture. Then, the water conduit adapter inserted through the solar panel apparatus and support base is mechanically connected to a water outlet of a pump to form the solar panel water pump assembly. The pump is electrically coupled to the control circuit board box via electrical connectors. Afterward, the solar panel water pump assembly is installed in an underwater environment in a water display.
