I have a 10'x10' shed that gets hot as hades inside, and want some ventilation involving pushing air through a hole I would punch in a wall near the roof peak and screen over so my friends the wasps don't move in. With a gas-powered mower and weed whacker, gas cans, and spare propane tanks for the bbq and camping lantern, it gets thick with fumes, and I'm uncomfortable with how hot it gets in there.
I have myself a salvaged solar panel in a weather-proof frame, which in its former life charged a battery that then ran a string of little LEDs at night. It being March, I don't know what to expect from summer sun in terms of juice production, but I did test with a single 60w incandescent bulb in a reading lamp pointed directly down at the panel. The multimeter registers 6.5v/1.3a at a distance of about 6", and with the bulb just about directly over the panel, just barely 9v/2a. This is direct from the panel; the battery and charging bits have been removed. They had stopped charging and/or holding a charge, which is how I inherited this.
I have a fan in this vein that came from an old external hard drive enclosure which puts out enough air, I think, to do the job: en.wikipedia.org/wiki/Centrifugal_fan
It's marked 12v/0.38a. It would be inside the shed blowing through the opening I make. Solar shed vents sold for this purpose are $40+ and reviews say they all just plain suck and are worthless.
What I'd like advice on is how to take this panel's output, which I can't imagine ever getting above the 9v/2a number, and probably hoping for the 6.5v/1.3a is optimistic, stepped up to 12v at sufficient amps to turn this fan. I found the items below which to my novice eye seem like they might be steps in the right direction:
Am I out of my mind? Could a device like one of the above take the panel's output and put out enough to get me 12v/0.38a if I get enough direct light? Is there some other, better way to go about this based on the panel I have?
