The course is too basic, there are no equations, no specific descriptions of the types of PV systems, software to calculate energy yields, nothing. More than that, there are no prepared technical slides or relevant images, is just the professor talking and talking.... and talking.

Great course! Information is well presented and organized. You'll end this course feeling confident on designing your own solar system, as well as gaining knowledge in other renewable energy schemes.

great course and I like the prof way of teaching so much, such a cool person. I highly recommend any one to come and "Explore" this course on Photo voltaic, Wind and Hydro Energy.

This course was really interesting. It cemented my basic foundation on renewable energy; solar, wind and hydro.

The Course is a good introduction to PV and Solar Energy, although it is only an introduction and is too basic and simple in my opinion - really beginner level, quick and easy, but I did enjoy it

To be honest, I also struggled with the English/spanish accent of the teacher, which did not make it easy. beginners will like that the teacher speaks in simple terms, with metaphors and examples, so that everyone can understand.

There are other courses on Coursera that will give you a better or deeper understanding of Solar Energy etc, such as the one from DTU (Denmark) for instance.

The teacher is somewhat difficult to follow, searching for words. I playd the vides at 1.25 speed which, made it easier to follow him. formula 'sand theories were not very well explained. Training was not at an acedemic level.

Soporific course, an interesting topic made boring with hours of talk and few materials. Would be great to offer, ppt, slides or hands-on tools.

its best course for beginner and specially for those who love renewable energy and its importance.

its a great opportunity for both students and field engineers who love to work on solar panels :) .

and specially thanks to great course instructor who made every thing clear.thank you coursera and thank you University of Pennsylvania

Hello, thank you for your efforts in the course. It was very useful and beautiful. I hope you will always be healthy and happy. Mohammad Pakzad from Iran.

This was a nice high-level survey of some renewable energy options but I felt it lacked the depth required to put together a good system off-grid, which was the stated goal of the course. In particular very little attention was paid to the batteries, which will be the most expensive part of an off-grid solar system. I also felt details on how to size the required components was weak. I did learn some useful things from the course but overall I was disappointed.

Such a wonderful course for a beginner to renewable energy systems. We all know about renewable systems to a degree, but through this course, one gets a solid understanding of the basic fundamentals and introduces new perspectives and criteria essential to running a successful system. Professor Santiago does a really good job of connecting the course material always to developing a real system. The additional readings are a great source as well.

Thanks Dr. Jorge Santiago for this excellent course, where I had the chance to explore renewable energy concepts. I liked the methodology and pedagogy whic h helped me to assimilate clearly the basics of PV solar , eolic and low head hydroelectric systems. This course has motivated me to go farther in the study of PV Solar System, which is a technology that may be be easier to undertake in household projects.

This is a great course indeed, presented by someone who is patient and very passionate about the subject. I enjoyed it all the way and would recommend it to anyone else. Now I am going to get that certificate and study further! Thank you Doc, and thank you so much to the University of Pennsylvannia.

Instructor was very knowledgable and easy to follow. The content coverable was more than expected and I learned a lot in this course that I will be able to apply to my real life living. Lots of excellent resources that I have booked marked to continue exploring solar energy.

The course was very well structured and the lectures were extremely complete and informative. A beginner to understanding renewable energy schemes will undoubtedly learn the basics. I appreciate the contributions of prof. Jorge Santiago-Aviles.

Great course!!! Well presented and organized. You'll end this course feeling confident on designing your own solar system, as well as gaining knowledge in other renewable energy schemes

This course provided a well organized information regarding Renewable Energy Schemes and how can we design a system to provide energy at smaller level.

Exploring Renewable Energy Schemes, That is very helpful, I'm very glad to join in this experience with a team of Coursera, many thanks for all of you.

very good course i toke more information and enhance my knowledge. More thanks and love to the best cool prof who presented the course.

Overall, I am quite happy with this course. It may be a bit too short and general for me being a mechanical engineering student, but I found it quite interesting. I was happy to find a course in renewable energy as I have interest in sustainability and environmentally friendly projects, I feel it is important for courses like this to be available to the public as it is something that should be greatly encouraged. This course was very solar energy focused which works for my country, but it would be nice for the course to go into more detail on other renewable energy schemes as well. Dr. Jorge was good. Although it can be a bit difficult to understand him at times, and there may be a bit too many pauses when explaining something than I’d like, I found him quite entertaining and after a few videos I got used to his style. He seems like a very nice man.
