COURSE CONTENT

Student Learning Outcomes:
At the conclusion of this course, the student should be able to:

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:

At the conclusion of this course, the student should be able to:

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.
