Omubo-Pepple, Chigozie Israel-Cookey Department of Physics, Rivers State University, Port Harcourt, Nigeria Abstract In this paper we have developed a data logging and monitoring system, we validated the system by comparing the result from it with the existing one and found that the system performs slightly better than the existing work in the same area. This implies that the data logger and monitoring system is good and can be used to monitor solar energy variables even at the comfort of our homes. We fitted a model to the generated data and found that the me- teorological variables considered accounted for 99.88% of the power output in the rainy seasons while 0.12% of the variation was not explained due to other factors. Solar panels inclined at an angle of 5 0 (Tilt) and facing South Pole perform optimally.

Introduction Solar photovoltaic (PV) energy system is regarded as one of the reliable, accessi- ble renewable energy sources. In several places where there is an abundant level of solar energy, a solar power plant is the best form of generating electricity. Hence, solar photovoltaic systems are being more and more utilized in solar home system (SHS), commercial industrial grid and there is a growing need to develop a real time monitoring system of data generated from PV systems to enable proper optimization of its overall performance. Therefore, A PV data logger and monitoring system is an electronic instrument that records digital, How to cite this paper: Tasie, N.N., Sigalo, F.B., Omubo-Pepple, V.B. and Israel-Coo- key, C.
