Determination of solar insolation in Michael Okpara University of Agriculture Umudike using a photoresistor

Abstract

The average daily insolation in Umudike has been determined at a figure of 7KWhm^-2 per day using the correlation between solar insolation and the solar resistance of a cadmium sulphide photoresistor cell. With this figure of insolation, Umudike falls within the high insolation zones of the globe. This is in accordance with NASA (2002) report. The community therefore has enough radiation to support not only agriculture but also high level solar projects.
