The probability distribution of hourly solar irradiation for Kumasi –Ghana was conducted using 14 years of data of measured values by the KNUST SOLAR LABORATORY. The analysis was carried out to find out the probability distributions that best fit the data of a given month of the year. The analysis conducted, revealed that solar irradiation for January, March and May can be fitted with the lognormal probability distribution. The month of April can be fitted with the Exponential, Weibull, lognormal Geometric and Gamma distribution while the months of June to December can be fitted with Exponential, Weibull, Geometric and Gamma. The paper finally concludes that the solar irradiation distribution in Ghana is not normally distributed with the above mentioned distribution describing the respective month of the year.
