In this work a preliminary investigation of the average daily solar insolation in Ihite Uboma LGA of Imo State, South East Nigeria, has been made. Method employed the use of the correlation between solar insolation and the solar resistance of a cadmium sulphide photoresistor cell mounted within the locality. Experiment suggests that the location has average daily insolation figure of about 10.0kWhm-2 per day. In comparison with NASA’s report of 2002, the LGA appears to fall within the high radiation zone of the globe and so can support solar projects. This investigation is informative and should attract the attention of both government and non-governmental agencies that are interested in solar energy harvesting for domestic and industrial use as well as the global battle against CO2 emissions.
