Influence of Meteorological Parameters on the Efficiency of Photovoltaic Module in Some Cities in the Niger Delta of Nigeria

This paper reports the investigation of some metrological parameters on the efficiency of photovoltaic module in some areas in the Niger Delta region of Nigeria. Results obtained show that efficiency of solar panel is directly proportional to solar flux and output current. Also, that increase in solar flux results to increase in output current of solar panel and enhance efficiency. It was also observed that relative humidity reduces output current and increases efficiency.
