THIS CHAPTER EXAMINES PV module fundamentals in detail. It also
includes a discussion of the differences between PV cells, modules, panels,
and arrays. This chapter also contains electrical output parameter infor-
mation and an in-depth look at the effects on PV systems from different
sources.
Information is included on the components and construction of flat-
plate modules as well as how to determine the power output of PV mod-
ules. Bypass diodes are then discussed. The chapter concludes with a look
at how to maintain the safety and reliability of PV modules.
