DC off-Grid PV System to Supply Electricity to 50 Boats at Gaza Seaport

This work presents an off-grid solar energy system at Gaza seaport to power fishermen boats’ lights needed for night fishing. The design process started by assigning the project site which should be close to the port. Then, the energy consumption and the percentage of energy loss are calculated. Followed by estimating the number of batteries that needed to power the lights of each boat. Finally, the number of solar panels and their angle of inclination are calculated. The designed system consists of: 7 independent sub-arrays, each one consisting of 2 photovoltaic PV strings, each PV string consisting of 4 modules, and 30 batteries each 6 batteries connected in series. The total PV modules for this project are 56 modules with a total power of 20.160 kW and the total batteries are 210. The estimated cost of the system is found to be ${\$}2,527,700$. The system will provide enough power to light the fishermen boats lights, decrease dependency of the fossil fuel and mitigate the environment hazardous emissions.
