As the world population increases geometrically, world food production is not sufficient in meeting the demand of the ever increasing population. Africa is not left out in the increase in food demand, especially Nigeria being the most populous African country. Most times, it is not that food is not available, but how well are we able to preserve the ones available so that they do they perish. Most food preservation methods are energy dependent such as the electrical energy, heat energy from fuel combustion, etc. Most of the developing countries are having problem of instable electric power supply and Nigeria is not left out. Thus the food preservation methods are not effective. Hence, in light of the above, the use of solar energy in Nigeria is very favourable. Nigeria, located between latitude 4°16"N and 13°32"N, is endowed with abundant sunshine all year round, with daily sunshine hours in the southern part averaging about 8 hours during dry season and about 4 hours during wet season.
