HOW STUDENTS FEEL ABOUT SEI

Luciano D
The PV 101 online course offered by SEI was an invaluable resource for me as it both allowed me to learn at a comfortable pace, never feeling stressed out about the deadline, and also challenging me to stay focused and really let the lessons sink in. Navigating the website was a breeze, which was accessible 24/7. All the lessons were very clear and easy to follow in my opinion, sometimes requiring me to slow down and often replaying certain details, but still easy and clear to follow along. The presenters are great, the quizzes reasonable, and the instructors were accessible to answering any questions. I can honestly say that this course met my expectations and even exceeded them for being an entry level 101 course. For that I am quite content and I plan to continue taking more courses here at SEI online.
Maneesha Madhuhansi
I would like to sincerely thank the SEI team for providing these valuable courses free of charge. I am genuinely grateful to have found this program, and it has greatly supported me in stepping forward on my career path.
Divine Ejike
The course I took was really packed with knowledge and insights for anyone who is willing to learn about Solar and renewable energy. I would highly recommend SEI. I also loved the delivery from all the instructors. A big thank you to SEI for putting the Intro to RE100 together and making it accessible and free.
Miguel Benero
I just want to express my deepest gratitude for the opportunity SEI provided me to participate in its solar installation training program.

This experience has been profoundly enriching, both professionally and personally. Thanks to the course, I was able to strengthen my knowledge as a licensed electrician and acquire new skills in the field of solar energy. This training has opened doors for me to work as a solar system installer, allowing me to help my family achieve greater energy self-sufficiency by installing battery-based systems. This has been especially valuable in our community, which has faced repeated tropical storms over the years.

Furthermore, the course has inspired me to support others in transitioning to cleaner energy sources, promoting independence from fossil fuels and fostering energy resilience in our region.

I would like to sincerely thank the instructors, who were always available to provide guidance and support throughout the entire process. The fact that the course was offered in Spanish was essential to my learning, as it allowed me to better understand the material and successfully pass the exams that assessed the knowledge I had acquired.

I encourage other professionals interested in the solar field to consider this opportunity, as it can represent a meaningful change in their lives and communities.

With gratitude and respect,

Solar Energy International does what many in the industry fail to do, by making available free introductory courses that can clarify what the renewable energy industry is all about for those interested to learn what an inevitable future will look like, and for those that want to be part of it.
Twyla Hermann
Such an interesting solar energy school. I found it while visiting Paonia and declared if I could ever put the time and money together at the same time I'd be back to take classes. That time happened for me this year. OMG! I'm enthralled. I highly recommend.
Ella K
This course was a very good experience for me. I enjoyed the lessons and the way the instructors explained everything. The atmosphere of the course was wonderful, very supportive, and it motivated me to continue. I am very thankful to SEI and to our instructors.
Muna A. Adem
I recently took my first solar energy course with SEI, and it was an excellent introduction for beginners. The course was informative, well-structured, and covered the key areas needed to build a solid foundation. It even inspired me to believe that the sunlight I see every morning could power a village—or even a house—helping students learn elsewhere! I especially appreciated the materials, though adding more examples from international solar projects could make it even stronger. Highly recommend SEI for anyone interested in renewable energy!
Agobeazim Ugbode
The online SEI free course is excellent. The tutors make the course easy to understand and enjoyable. This is a very fascinating field and very useful for development in the developing world. I am fascinated by the preparatory free course and would like to study the recommended courses. The deal is that I would need to practice the theory. I live in England where access to practice is a little bit difficult.
