Abstract
This chapter discusses the photovoltaic (PV) characteristics, performance, modelling, maximum power point tracker techniques and grid interconnection. It covers four different PV generator models with their characteristics and their performance analysis. In addition, the four most famous conventional MPPT techniques with some of the soft computing MPPT techniques have been discussed including detailed comparison, assessment, and discussion with the limitations, merits and demerits of these MPPT techniques. Interconnection of the PV energy system with electric utility has been discussed at the end of this chapter.
