Abstract
The release of polluting gases such as NO/sub x/ of SO/sub x/ to the atmosphere from ships is causing increasing concern. To reduce destruction to the marine environment, the value of the utilization of photovoltaic energy is highly appreciated since photovoltaic energy is and alternate clean energy source to fossil fuels. The use of a photovoltaic generating system to supplement diesel engine driven electric power system on ships has been studied. The design of the photovoltaic generating system based on a photovoltaic array is presented in this paper. The amount of NO/sub x/ and SO/sub x/ emission is found to be significantly reduced for a small vessel operated within a harbour after a photovoltaic generating system is installed to supplement the diesel engine generator system.
