Abstract: The solar-radiation over Osogbo (7°47"N, 4°29"E) was estimated from sunshine-hours to determine the available solar energy for deployment of solar photovoltaic technology applications. The computed mean-monthly daily solar-radiation ranges from 10.30 MJm−2day−1 (August) to 18.10 MJm−2day−1 (February). Analysis of daily wind speeds shows an annual-mean wind speed of 3.5 m/s at 18 m height with peak values of about 4.9 m/s occurring correspondingly at the peak of the rainy season. This study shows that wind power can compliment photovoltaic applications. Batteries can be used to overcome the well-known variability of wind power. In a pilot scheme, a wind turbine with low cut-in speed of 3 m/s was installed at 18 m height to compliment a 400 Wp solar module and a 4.8 KW-hrs battery-bank/inverter system, to form a robust hybrid alternative power system. The study establishes that wind resources of wind-power class-2 and above can compliment small-scale photovoltaic systems to overcome lower performance challenges during periods of heavy cloud-cover.
