Chapter 10

Modules, Inverters, and Solar Photovoltaic Systems

Abstract

Individual silicon solar cells are formed into modules by connecting them in series and parallel. These modules are subsequently encapsulated to protect them from natural elements before they are deployed. Thin film cells can be much larger than silicon cells, and one thin film cell may form a single module. The cell output is direct current, which must normally be converted into alternating current at the grid frequency in order for a solar installation to interface with the grid supply. Conversion is carried out with a device called an inverter. When the cells are part of a utility-scale power station, there will also be a dedicated transformer substation to interface with ...
