Intended Grade Level(s):
Estimated Activity Length:
3 hours
Learning Goal(s):

Students will be able to describe the basic structure of a photovoltaic solar module implementing the ideas of series and parallel wiring. Students will be able to describe the basic structure of a photovoltaic solar array implementing the ideas of series and parallel wiring. Students will be able to describe the function and necessity of an inverter when using photovoltaic arrays.

Description:

This lesson begins with basic chemistry with regards to atomic structure. The lesson then moves to understanding the special properties of silicon as a photoelectric semi- conductor. Building on this, the basic structure of photovoltaic solar cells is described in detail.
