Abstract
A total of 42 different empirical model equations for estimating global insolation from other meteorological parameters is discussed and their predictions compared with measured values for Port Harcourt. The parameters are sunshine hours, relative humidity, temperature as well as geographical declination, latitude and altitude. It is found that a number of the models give significantly the same level of prediction. The average error in the calculated insolation being between 1.7 and 2.6 per cent (maximum deviation less than 7 per cent) when 8‐year monthly average data are used. Utilizing the individual monthly average or daily average data resulted in higher errors in the range 6–7 per cent (maximum deviation less than 33 per cent).
