It's not a commercial panel. I strung several Evergreen cells together that I got awhile back on ebay. Plexiglassed them together and it powers the PC fan well. I just didn't want to burn it out. My wife is tinkering with a Solar air heater and she wanted a fan to help move the air along...
Your car analogy is great. Thanks for explaining that to me. It figures I would have heavy cloud cover today and the panel has 0 output. I want to check that voltage while the fan is going. Thanks for your help Mike.

Indoors, next to a window during partial sun my meter said 1.1amps I hooked up the fan and it was running at what felt like 100% This is the reason I was worried about connecting the fan outdoors in full sun. Outside in direct sun the meter says 3.4amps. Do I ignore the amps, and measure...
Looking for some guidance with hopefully a simple question - I have a solar panel that generates 9v /3.4amps in full sun. I want to hook it up to a 12v pc fan that is rated at 0.88amps. Do I need a resistor or anything to prevent any damage to the fan?
Thanks,
Frank
