Feb 21st – March 28th:  Weekly Zoom Q&A sessions and Chapter Review

April 15th:  In-Person Hands-On Labs

April 16th:  Exam Review and PV Certification Exam >

This Residential Solar Installation & Design hybrid course is a comprehensive learning experience designed to take students with little or no background in electrical systems and/or solar photovoltaics. The course provides solid foundation for those wishing to enter the industry, design and install their own residential PV system, or simply understand how this emerging and important technology works. By the end of the course, students should have all the skills necessary to design and install residential-scale solar electric system.  Students will also be certified (assuming you pass the examination) as a Level 1 ETA PV Installer – a credential recognized around the globe.

So how does the solar course work?

Online Self-Paced Study:  Registered students will have access to the 46-hour online Residential Solar Installation & Design course.  This course tracks with the provided textbook (Understanding Photovoltaics), and is organized into 11 chapters, 71 major topic areas – with 11 review quizzes, 25 lab projects, over 550 narrated slides, dozens of integrated videos, links to online resources and materials for added comprehension and more. Upon registration, each student will be given access to this program and can begin studying at their own pace.  But most people need a bit of structure – so that will be provided as well with weekly Zoom sessions.  While this session is designed to begin on Feb 21st – you can start earlier if you like or even join us a bit later and catch up.

Instructor-Led Study Sessions:  Beginning Feb 21st, instructor-led sessions via Zoom will be held to walk through each chapter and session, clarifying difficult concepts and reviewing the most important highlights.  These sessions will take place once a week for six weeks (Tuesdays at 1 pm eastern).

Instructor Availability via E-mail:  Often questions arise and can’t wait for the next Zoom meeting.  An instructor is available to answer questions via e-mail throughout the course.

Hands-On Labs:  On April 15th, we will host the course hands-on labs (in Greencastle, IN), that provide opportunity to work directly with actual PV systems and also fulfills the hands-on requirements of the ETA PV Level 1 certification.  The hands on labs take a full day to complete. The student can choose which day best meets their schedule.  Students will work in small groups and follow appropriate COVID-19 protocols (if that is still an issue).

Remote Hands-On Option:  If it is not possible to travel to Greencastle, IN to take the hands-on portion of the course, it is possible to proctor the hands-on tasks remotely (see task list below).  In order for students to comply with the ETA certification requirements for remote hands-on testing they will need access to the appropriate equipment and materials.  Contact the instructor for more information.

Certification Examination:  We will host an examination session on April 16th in Marietta, OH for those who prefer the pencil an paper option.  We we hold a comprehensive review session in the morning, followed in the afternoon with a proctored exam.  Remote proctoring is also available at a time scheduled by you if you cannot attend the in-person examination.

Remotely Proctored Certification Examination:  ETA now offers remote proctoring of their examinations through ExamRoom AI.   In this way students can take the examination from their own device, with a live remote proctor monitoring the process.  Help is available to walk students through the process of registering for the examination.  The certification examination fee ($155 to ETA) is included in your course registration.  However you will need to pay the $14 proctoring fee to ExamRoom AI when you schedule your examination (details on this process will be provided during the class). The examination consists of 75 multiple choice questions (with a 2-hour time limit).  Passing score is 75%.

This course prepares students to sit for the ETA Photovoltaic Installer (PVI) Level 1. It is the first level of ETA’s certifications designed to assess renewable energy professionals. It is also a great first step for those seeking to enter the PV industry, and perhaps later prepare to sit for the ETA Photovoltaic Installer Level 2 or  NABCEP PV certification programs. 

 
Some jurisdictions (the state of Illinois, for example) require certification in order for an installer to install PV systems or apply for solar incentive programs.  The ETA PV Level 1 certification meets these requirements in most cases.
 
This course is offered  in partnership with several not-for-profits.  The fee for this six-week course is $599 and includes:  Instruction, hands-on labs, textbook and lab material, and ETA examination fees.  This course may be eligible for VA and Americorps funding.  Scholarships, on rare occasions may also be available based on need.   Group discounts may also be available.
