Empowering Communities. Honoring a Legacy. Expanding Global Access to Solar Energy Education.

Empowering Communities. Honoring a Legacy. Expanding Global Access to Solar Energy Education.

The Johnny Weiss Solar Energy For All Initiative continues the legacy of Solar Energy International’s co-founder Johnny Weiss, who believed renewable energy training should be accessible to everyone. While SEI has trained over 150,000 people in 100+ countries since 1991, an estimated 775 million people still lack electricity access, with many still experiencing unreliable power for daily needs. This initiative specifically targets underserved communities where energy access is literally a matter of life and death, bringing solar education and training to those who need it most as part of SEI’s broader mission to address the persistent global energy gap.

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.

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.

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!

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.

The people of SEI really care about your understanding of renewable energy! This review is based on taking the online course RE10 Introduction to Renewable Energy.They take a multi-pronged approach to learning, including education (videos and copies of slides), training (interactive activities), and testing (quizzes) that reinforces knowledge gain, no matter what type of learner you are!The other quality I admire about this course, as someone who does an enormous amount of online learning, is SEI's care for balance in the design of the course characteristics: length of sections and lessons; complexity of content given the context of the course being introductory (technical versus unnecessary technicality); pace of delivery of information in the videos, passion of the instructors, and overall comprehensiveness are something they have clearly spent many hours trying to get just right!If you want to understand renewable energy, with a focus on solar, as a beginner this is one course that will give you the confidence to ask intelligent questions moving forward.

So far, I've taken SEI100, the free course, and plan to take my first solar paid class next. The free course provided a technical foundation for a layperson like me to learn more about renewables, the electric grid, basic electricity science, solar, and issues in less developed areas. It was engaging and easy to finish.
