    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!
