Abstract
In this paper, electrical energy demand (load) of health centre at Ibeno beach in Akwa Ibom, was estimated based on watt-hour energy demand of the electrical appliances in the health centre. The estimated daily load demand is 35 kWh/day with peak load of 7.735 kW. The sea ambient temperature is about 8% lower than that obtainable on land while the wind speed on sea is about 67% higher than the wind speed on land. The cumulative effect of the lower offshore temperature and higher offshore wind speed is offshore PV cell temperature that is about 18% lower than the PV cell temperature on land. The system is designed with 3 days of autonomy and the resultant load demand will be satisfied by 11.41 kW PV modules and 4765.8Ah battery capacity which amounts to 64 units of the selected PV panels and 24 units of the selected battery.

The results of the numerical computations of the Offshore PV system are presented in the tables 5 and 6
The lower offshore water temperature and higher offshore wind speed ensured that the PV cell temperature is about 18% lower than the PV cell temperature on land
Summary
The sun provides the energy to sustain life in our solar system. The earth receives enough energy from the sun to meet its energy need for nearly a year [1, 2, 3, 4]. Harnessing solar energy to power electrical appliances starts by converting the energy from the sun to electricity. Photovoltaic (PV) is the direct conversion of solar energy into electricity. PV systems can be used to exploit the solar energy in almost all applications. With fossil fuel resources expected to be depleted in the years ahead, PV Power systems provide a means of providing electricity and addressing concern for fuel supply security [5, 6, 7, 8]
