It is in this module that the student learns the principles of solar panel construction and the various types of PV panels in use. The five main solar panel PV materials are described and the effect of shading on a solar panel is explained in detail. An introduction to Standard Test Condition (STC) is presented and the function of MC4 connector are explained. Wiring methods for solar panel strings are described with an emphasis on industry best practices. The impact of temperature coefficient on power loss is discussed and examples of calculating solar panel efficiency, as well as tilt and orientation factor (TOF) are presented.
