Finalizing Solar Energy Project Ideas for a First Year Class

Hi all,

I am currently a first year Electrical Engineering student who is finalizing ideas for a solar energy product for my Design Thinking class. As of now, I have four ideas relating to solar energy/ hydropower that I am considering prototyping, and I am looking for some professionals in energy to contribute to a 30 second – 1 minute survey that I created to rank these four ideas based on what you all believe would be the most feasible to prototype and eventually build: https://forms.gle/DaWTrSQSvaDZBu6o8

Thank you all for advance for considering my survey!
