What is a solar PV module?

Solar modules, though similar in design (silicon crystalline-type) will vary by size and power produced. Readers are encouraged to refer to the Extension factsheet, "Demystifying the Solar Module" (AZ1701) for information about solar PV modules. Simple systems have fewer components, but are limited to providing energy when the sun is shining.
