Seasonal daily nonrandom cloudiness is typical in many geographical locations. Optimization of flat-plate solar collectors orientation in such situations requires azimuth and tilt modifications from those when daily cloudiness is random. The present study evaluates the significance of optimizing solar radiation gains, while considerating an illustrative case of nonrandom afternoon/morning cloudiness. Results suggest that for fixed flat-plate collectors the related gain in solar energy is practically insignificant. For nonfixed collectors the solar energy gains can be improved on a monthly basis by up to ∼6 percent.
