DIY, homemade solar panel. Final project for Alternative Energy with Professor D. Bowden (University of Massachusetts). 12 5×5 0.5V 2.6W monocrystalline solar cells wired in series. This video chronicles my efforts to make a homemade solar panel from scratch, start to finish. Added a little levity in there to make it less dry and a little more fun. Enjoy!

Please make sure to work in a well ventilated area! Lead is very toxic!
This video shows what items and tools are required for making a solar panel. And how to go about making one. Individual broken solar cells are soldered together to make a solar panel. The panel can be made any size.
The voltage needs to be high for it to be dangerous.
V/R=I
If R is very large I is small (body resistance)
So large voltage is needed to increase I
I or current is dangerous flowing in body.
