Abstract: A study of the effects of relative humidity on solar electricity generation was carried out in Uyo and Port –Harcourt cities. Their results were compared to ascertain which city generates more solar electricity in relation to relative humidity of the city. Relative humidity, output current, and output voltage, were measured using digital instrument. Also formal meteorological data were utilized. Analysis show that, relative humidity is higher in port-Harcourt; > 93% in the morning hours, >70% at noon hours and >80% during evening hours, this giving output current of; <10x10-1A in the morning hours, »15x10-1A at noon hours and <8x10-1A in the evening hours. Also power efficiencies of; <50% in the morning hours, »65% at noon hours and <35% during evening hours were recorded. While in Uyo city relative humidity is lower with values of; <90% in the morning hours, <65% at noon hours and <70% during evening hours, also output current of; >15x10-1A in the morning hours, >20x10-1A at noon hours and <18x10-1A during evening hours. Efficiencies of; >60% in the morning hours, >90% at noon hours and >70% during evening hours was recorded. Result shows similarities in trend in the effects of relative humidity on the output current, output voltage and power efficiency of solar module in both cities. Observation shows that at low relative humidity, output current increases as well as power efficiency of solar module hence solar electricity generation is high and vice vase. These implies that solar electricity generation is higher in Uyo while relative humidity is low than in Port-Harcourt where relative humidity is high.
