Generating and Conserving Energy is one of the most important concerns in several countries in view of the piece of evidence that they have inadequate resources of energy to depend on, and they may be import all their needs of energy from other countries. Consequently, many conventions have been held push for the public to demeanor the consumption of energy. Conserving energy of public road lights using photovoltaic solar system could be used to trim down the power invoice by generating and controlling the lights of street lamps in the public road and will save a lot of energy (Meridji et al., 2013).
This section presents an overview of the related techniques used for integrated our proposed system of photovoltaic solar system and sound biometric techniques on what say called system on chip.
Semiconductor material normally composed of the silicon and is used in slim wafers or ribbons in most commercially existing cells. One side of the semiconductor material has a positive charge and the other side is negatively charged. Sunlight hitting the positive side will activate the negative side electrons and produce an electrical current (Sakai et al., 2006)
