A mathematical model for determining the optimum angle of inclination for flat plate solar collectors was adapted for major towns in Nigeria. The optimum angle of tilt of the collector and the orientation are dependent on the day of the month, month of the year and the location of the site of study. This varied from 0 to 35 degrees for the major towns in Nigeria. The model was able to predict the best day of the month. That is, the 21st day of the month when the insolation is usually the highest. When the collector is inclined at the actual angle for a particular month, the absorber with minimum reflection and absorption at the cover glass absorbs maximum solar radiation. Hence, the collector angle of inclination can be made adjustable for the collection of optimum solar radiation for different months of the year.
