PVOL203: PV System Fundamentals (Battery-Based) (40 Hour Course) Class Information
Document ID: 8AF5
Description: PVOL203: PV System Fundamentals (Battery-Based)(40 hour course)

Energy storage has been a part of many PV systems since the beginning, but now the market is growing like never before. In PVOL203 the focus is on the fundamentals of battery-based PV systems. The applications and configurations are many, and their complexity far exceeds that of grid-direct PV systems. Components such as batteries, charge controllers, and battery-based inverters are covered in detail, along with safety and maintenance considerations unique to battery-based systems. Load analysis is critical to system design and will also be addressed along with other design criteria such as battery bank configuration and the electrical integration of the system. Course learning outcomes include:
  • Recognize demand and PV production curves
  • Explain why energy storage is useful
  • Identify the common types of PV systems and their components
    • PV Direct
    • Stand-alone
  • Describe charging options
    • DC and AC coupled
  • Discuss load profiles, modes of operation, energy management, and storage
    • Stand-alone
    • Battery backup grid-tied

This course is entirely online and does not include a hands-on lab component. You can log into this course at any time, 24 hours a day, 7 days a week for the full duration of the specified course. You will generally need between 7-10 hrs/week to complete the lesson materials and graded activities. The earlier lessons generally take less time than the later lessons. Students can access the course anytime, from any computer with an internet connection (access computer requirements link below). There are no specific times that you need to log on; the course is self paced but you must finish all graded materials by the end date of the course. The live instructors are there to give feedback, grade your work and you can contact them with questions on the forum discussion boards, or by email.

This course includes interactive activities, powerpoints, readings and quizzes, and exercises and homework to test student comprehension. There is also a forum where students can post questions to the instructors and network between each other. Online courses last six (6) weeks and will end on the Sunday night of the last week. All graded course activities (e.g., quizzes, forum discussion assignments, any other assignments with a score) need to be completed within these 6 weeks, with a 70% or better cumulative grade, to pass and receive a Record of Completion. After the course end-date, you will have two additional weeks for instructorless review-only time. During this time you will not be able to complete any graded activities. However, this is an ideal time to finish saving and reviewing any course materials of particular interest.

Successful completion of this course results in 40 State of California Journeyman Continuing Education or Electrician Trainee hours.

This course also counts as one of the two courses required to qualify students to sit for the NABCEP PV Associate Exam. The other is PVOL101.

The course additionally results in any of the following NABCEP Training Hours:
  • PV Installer Certification Requirements: This course counts for 20 advanced training hours.
  • PV Installer Recertification Requirements: This course counts for the following:
    • 6 Job Task Analysis hours
    • 6 Non-Technical hours
  • PV Technical Sales Certificate or Recertification Requirements: This course counts for 6 Non-Technical/Other hours
  • PV Associate Recertification: 12 training hours
  • Solar Heating Installer Recertification: This course counts for 6 Non-Technical continuing education hours
Prerequisites: Before participating in the PVOL203 course, students are required to complete PVOL101, an equivalent course from another organization, or demonstrate field experience and pass a placement quiz. Please contact sei@solarenergy.org if you feel you are qualified to skip the prerequisite for PVOL203; they will notify WECA of your equivalency if granted.

Students will receive a confirmation email from Solar Energy International with course log on instructions within seven business days prior to their class start date. All course materials will be accessed through the course.

Required Course Materials: You may want to have your copy of the Solar Electric Handbook on hand from your PVOL101 course.

All course hours must be completed within Solar Energy International's designated course timeline for this instance in order to receive credit.
