Solar System Fundamentals (PVOL101, PVOL203, NABCEP Exam +Solar Safety Training Package)
The FY23 installers training package includes: Solar System Fundamentals (PVOL101, PVOL203 and the NABCEP Exam – also referred to as the NABCEP PV Associates Exam Prep Package) and Solar Safety for residential/commercial roof‐mounted installations and for large‐scale ground‐mounted installations (also referred to as the Solar Safety Training Package).
Students who complete the training will be able to sit for the NABCEP PV Associate Exam. This exam will be scheduled prior to the October 2023 deadline, however the actual date of the exam may fall after the deadline, as it is administered by NABCEP (please see https://www.nabcep.org/certifications/associate‐program/ for more information about PV Associate installers exam);
Overview of PVOL101: Solar Electric Design and Installation (Grid‐Direct)
This training will provide an overview of the three basic PV system applications, primarily focusing on grid-direct systems. The goal of the course is to create a fundamental understanding of the core concepts necessary to work with all PV systems, including system components, site analysis, PV module criteria, mounting solutions, safety, and commissioning. The course will also cover the basics of sizing a residential grid-direct system, wire sizing, overcurrent protection, and grounding.
Overview of PVOL203: PV System Fundamentals (Battery‐Based)
The prerequisite for PVOL203 is PVOL101.
PV systems with energy storage are a rapidly growing segment of the industry. This course builds a foundation for understanding many battery-based applications, in which the complexity far exceeds that of a grid-direct PV system. Load analysis is addressed along with other critical design criteria such as battery bank design, equipment options, and electrical integration of system components. Component options are covered in detail, including batteries, charge controllers, and battery-based inverters. Solar Energy International ‐ Contract 4 Different battery chemistries, associated pros and cons, and cost comparisons are investigated along with safety and maintenance considerations unique to battery-based PV systems. This six-week training will be online, asynchronous, and facilitated by SEI instructors. Students will have daily assessments including exercises and quizzes to assess learning.
Overview of Solar Safety Training Package
SEI’s 20-hour Solar Safety Training Package consists of two On-demand Continuing Education (CE) courses focusing on the tools and skills to work safely on solar PV systems of various sizes. SEI’s Continuing Education program is aligned with the North American Board of Certified Energy Practitioners (NABCEP) approved topic list for re-certification. These sessions are offered as on-demand recorded presentations to provide flexibility for the busy professional. Present both Records of Completion that are received upon successful completion of the trainings to NABCEP to demonstrate OSHA-10 requirement*. These trainings are online, self-paced, and without instructors.
