Our Classroom

nabcepLogo ESI has partnered with Harrisburg Area Community College (HACC) to provide renewable energy training at our central office in Jonestown, Lebanon County, and HACC’s Harrisburg campuses.

ESI’s instructor, Mike Schmerl, is certified by the North American Board of Certified Energy Practitioners (NABCEP) and joined our team after previously teaching at Northwestern Michigan College. Mike was actually the first NABCEP-certified instructor in the state of Michigan before relocating to Pennsylvania to join ESI.

ESI offers a variety of courses in renewable energy, which are hosted at different times and locations to accommodate those with busy schedules. Classes provide a comprehensive overview of the specific technology and are designed for those seeking introductory instruction. Advanced classes are also available for tradesmen who already have a significant electrical background.

Typical topics which are addressed in class include:

  • Markets and Applications
  • Safety Basics
  • Regulatory and Policy Issues
  • Hands-On Workshop
  • System Components and Sizing
  • Government Incentives Available
  • Mechanical and Electrical Design
  • Performance Analysis and Troubleshooting
