In this chapter, we will find out how to get the most solar energy out of the sun by considering the time, the altitude angle, the radiation and the photovoltaic (PV) materials. A simple PV model helps to understand the mechanism of energy conversion - solar to electricity. We will further use a simple equivalent circuit to represent a PV cell to investigate its current-voltage characteristics.
