Motive● Current Generators problems

○ Loud○ Non-renewable○ Not Smart○

● A better Generator needs to be:○ Mobile○ Clean○ Smart○ Modular

Clean

3

● Gas generators run on Fossil Fuels (By definition exhaustible...)

● Our Generator runs on sun

Smart

4

How?-Use sensors to enable generator to react to surrounding environment.-Remote Deployment

Why?-Solar cells on their own degrade with more exposure to environment-Protect Panels from vandalization-By only deploying solar panels when needed increase lifespan of device

Panel Deployment Test

Light Intensity Test

Due to the fact that the light sensor is enclosed and does not receive full 360° light our readings are on average 0.55 compared to reference value. But the relative relationship is consistent.

Client Feedback

● The overall progress of the project surpassed my expectations.● The group demonstrated a remarkable degree of coordination

and division of tasks among themselves. ● Innovation in some aspects of the project convinced me that

the members of this group are ready for taking on challenging projects in the field of electrical engineering.

Challenges

● Keeping on schedule

● Integrating everything together

● Dealing with unexpected problems as they arose

● Handling real-life weather conditions

● Eliminating unwanted external noise

● Accurately measuring current

Future Work

● Creating another unit to make the units modular

● Make the open and close mechanism more robust

● Fully weatherize the unit

● Make device more lightweight and easier to maneuver.

Personal Learning Experiences

● Finding ways to communicate ideas clearly and concisely is hard.

● Expect things not to work the first time.

● Don’t overthink things, sometimes the simple solution works.

● Working as a team is difficult.

● Noise is real...and frustrating.

● Be flexible
