6.2. Connections in large PV systems

Power output from the solar arrays would be dependent on the arrangement and connection of the modules within the plant and can be varied based on local preference. To know how we can manipulate power output, we need to understand the principles of interconnections of PV cells in the modules and connections of those modules to the direct current equipment. From the following reading, you will learn about different types of connections and how they determine the module response to disturbances such as shading or formation of hot spots. Additionally, we will see how the module performance may be affected by different environmental parameters, such as irradiance, temperature, and type of solar cell material. Finally, this reading will describe how the cable connections are made between the solar modules and a generator.

Note: The quiz at the end of this lesson will include a few questions on this reading. Please refer to the Summary and Activity page for more details.
