COURSE CONTENT

Student Learning Outcomes:
Upon completion of the course, students will be able to:
Untitled document
1.  Explain photovoltaic module characteristics, specifications, and response to the Sun.
2.  Conduct a solar site evaluation for installation of a photovoltaic system.
3.  Optimally size utility interactive and off-grid photovoltaic systems to electrical demand.
4.  Select appropriate inverters and balance of system components.
5.  Perform a basic National Electrical Code (NEC) compliant photovoltaic (PV) array
    installation.

Objectives: Untitled document
During this course, students will:
1. Discuss the history of photovoltaic technology.
2. Use current-voltage curves (IV curves) to interpret photovoltaic response to sunlight and
    temperature.
3. Read a sun chart and understand Earth's movements around the Sun.
4. Chose appropriate personal protection equipment when working with PV.
5. Use standard industry tools to determine a site's shading and to measure the total solar
    resource fraction available.
6. Perform a load analysis for both utility interactive and off-grid system sizing.
7. Match PV modules to inverter by using both manual string sizing calculations and
    manufacturer's string sizing tools.
8. Select appropriate racking and balance of system components for roof and ground mounted
    arrays.
