This course prepares you 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.

This course is offered throughout the midwest in partnership with several not-for-profits.  The fee for this one-week course is $970 and includes:  Instruction, hands-on labs, textbook and lab material, ETA examination, and (in most cases) lunch.  This course is also eligible for VA and Americorps funding.  Scholarships may also be available based on need.  Contact us at 740-674-4300 for further details regarding the management of fees.

Early Registration Fee:  $970 (includes ETA examination fee, course materials and solar installation tool kit)*





ETA Member or Multi-Person Registration Fee:  $930 (registering two or more people for the course at the same time)





After September 1st, price increases to $1,070
