We now also have a lab facility in Costa Rica and the Middle East as well. Many of our workshops are held in other parts of the country and the world. For detailed info about Paonia click here. Lodging & Logistics: SEI’s main campus and Lab Facility is in Paonia, Colorado. If you are sending a check, call first to check on availability and to let us know that you are sending payment. To reserve a space you can register online or call in to register at 97 option 1 and make payment in full. Enrollment is on a first-come basis and class sizes are limited. Late enrollments will be accepted on an individual basis for online courses, and the first day of class for in-person and hands-on labs courses. Solar Energy International (SEI) is approved and regulated by the Colorado Department of Higher Education, Division of Private Occupational Schools.*Įnrollment: Prospective students may enroll anytime.
