Question 1: Interfacing solar array with
...
larger/heavier vehicle than standard cruisier
Requirements for integrating solar to power major vehicular functions of a regular car
Small frontal CRA
Light
Driving under 75mph
Bottom line: Not enough power for drivetrain
Question 2: For someone new in this environment, how to immerse yourself with solar tech
Solar car design team
PV Education.org
Solar Cell Operation
Keep up with the industry and the news in it
Work with different people in different fields
Think about how your skills can integrate with other people in the field to achieve vision
Question 3: Sunpower solar project - (one of the projects she is working on )
Use conductive adhesive to stick the panels.
Laser cut strips
...
Shingle panels together
Question 4: Biggest areas for innovation in solar array
Monocrystalline is current standard e.g:Topcon
...
etc (getting around 23% power efficiency)
Biggest areas of innovation then since max theoretical power efficiency is 29% would be cost :
Cost down
Using the module area better for the solar panels
Question 5: Keeping solar array clean and efficient during race
Make sure electronics are podded or protected in a water resistant enclosure
Make everything assuming that things will be completely soaked
Get waterproof heat shrink
RTV PV-804 (have to use special acetate-free rtv)
Have a hole underneath driver so person is not sitting in a puddle haha
Front sheets could use fluorinated polymers
use deionised water and microfibre to clean and keep it cool
Question 6: PCB Debugging
Highly recommend external IR camera
Inspect everything you make in IR
Observe your solar array when it is in the sun using IR; you could detect hot cells or broken parallel pathways or other issues
Ask FLIR for donation if possible : ) (if we don’t have one already)
...
Good for small resolution but the Fox and Hound is fine for automotive wiring
Really great for troubleshooting
