First prototypes. Today’s testing condition at 10-10:30 atlantic meridian. Hazy/Smoggy. Friday, August 19th, 2016. Temperature: 70-80f Humidity -50-60%
I built these in the summer/fall of 2013, they were originally intended as part of a 300+ watt array for an immediate install atop a vintage travel camper.
Now of course in engineering there are setbacks (or rather diy construction), there’s always a thomas edison cum-faced napoleonic asshole dispensing his squad of ignorant mafioso muscle men who threaten your life when you’re making and ruin your mojo for compounding projects. “Ignorance is bliss when it is folly to be wise and you’re a giant fucking ignorant lummox of a mafia goomba, said mr greenhouse gases to mr sustainability. Hiya tootz.. I mean sir.. Please drive your would be pittsburgh steel pick-up truck into a flooded river and get the fuck out of the teamsters union.
[You must use a “crafting” iron or an old soldering iron that will reach less than 700. A new one with 900-1000+ WILL easily burn through cells. Even if you’re a skilled technician, but due to the pressing involved, you really need a cooler iron. This is no circuit board. I’ve never soldered so much on one project.}
The intent is the lightest possible rigidity per cell without using a liquid resin for superior power:weight. The lexan is 2-3x lighter than glass of equal strength. Slightly less clarity over time, minor loss of voltage of lumens per square inch of illumination overall, but the performance matched the math in concept. Being that I live in a winter climate for other use, there is less heat warp as well as an increased voltage output in the cooler temperature. The losses are negligible relative to a desert environments’ heat soak losses.
10:30am October 2013, on a sunny clear crisp day they both produced 12-13+volts and the stronger panel hit 3.85 amps respectively with 20 cells. Individually they each weigh possibly lighter than 3 pounds. Noticeably lightweight for the output.
cells were not perfect and have minor laminate defects.
The camper is gone, and they weren’t stowed properly for (wow, years now) my cat dropped one. They still produce over 10v, so in series will still (as a pair) trickle charge 12v or 6v DC… etc. In the next video I’ll show how to make use of broken cells. Even the tiniest pieces still produce voltage no matter the mosaic. Pretty cool! 0 pollution. der cough cough+_sol
Now they will be used for an upcoming Super secret. Just don’t shake them assholes! There’s lot’s of math that’s involved…
LoL gasoline.
First part of the homer tutorial. It ends abruptly because the program crashes!
