donutz28, big thanks to you for finding the PDF, I've given up long ago and decided it wasn't worth the trouble to use these on anything productive
I've given 4 of them away to a friend who is in the process of making a battery operated 4WD wheelchair "for the fun of it" and hes using them to charge batteries.
the other 2 is now planted on my utility shed, connected to 8 12V fans and keeping the shed quite cool during the hot summer days. Its direct drive, so it'll throttle up and down in RPM throughout the day
Shed
Inter-tie under awning
Fans
can you believe that for the entire setup all I needed was the $1.25 terminal block? these fans were literally brand new and installed in a server tower that was thrown out and abandoned...so with a pair of dikes, a philips head, and two aftenoons I salvaged 16 of these fans, ~10 Gamma32 120mm blowfans, and numerous others including 3 2" thick block fans that pulled about 1.6A on 12V
One of the biggest hazard is the heat, the other is vapor concentration. The shed houses the wood workshop and lawn mowers, as well as being chock full of gasoline, 2-cycle gas, waste oil, new oil, lube oil, paint, primer, paint thinner, acetone, caustic solvents, rubbing alcohol, grain alcohol, solid fertilizer, liquid fertilizer, aersol cans, over a pound of potassium nitrate and a decent box of fireworks...now in all of this is where I solder, testing homemade incendiary devices [in a forced air 50cal steel can with a spark arrestor], and work on HV circuits that creates sparks. To help cut down on the noise the fans were wired 4S2P for 24V operation...its a good thing too because 1S8P the fans wont turn whatsoever [each fan was rated ~500ma and drew about 300 each] the modules are connected in parallel and peaks around 17V in full sun. the fans are estimated to be running at 50-60% capacity. I have another 8 wired in a similar manner on the adjacent window to vent out. On max it draws 12V 2.6A out of my 4A supply and when its on I can't hear myself think, but it sure does pitch out alot of air, even more than the box fan dad had installed. Being bigger than the window by over half it did the best it could swirling the solder smoke around the room instead of venting it out.
And yes, theres a pull chain switch that leads all the way out to a safe distance from the shed that I can disable the fans in the event of a fire so it won't fuel the mess by forcing in more air.
I don't plan on charging cells with these modules, I'm planning to invest in a single piece 50W module for that.
Can someone identify these panels?

I can't believe those were thrown into a scrap yard like trash! I don't recognise yours, but an internet search found these panels that look similar:
