Photovoltaic solar cells can serve as a reliable source of electric power for electronic instrumentation in 

 temporarily or permanently submerged marine systems in the form of bottom installations, buoys, or remotely 

 controlled unmanned vehicles. The power output of submerged solar cells is a function of solar insolation 

 intensity on the water surface, depth of submersion, optical properties of water, temperature, and the orientation 

 of the cell surface with respect to the sun. Experimental data were generated by submerging solar cell panels in 

 different bodies of water with a 2.5- to 95-ft visual contrast limit, as defined by the observation of a submerged,
