As my first foray into Solar DIY, I'd like to try to power a 5V computer fan with a solar panel. My goal is to run it for at least several hours per day. My understanding is that I'd need the solar panel (duh!), a fan, a charge controller, and a battery. As a newbie, I'd like to run my setup by this community since you know better than I do. Please let me know if this makes sense:

Steps:

  1. Strip end of solar panel wire and attach to charge controller
  2. Connect micro USB cable to battery bank and strip the other end to connect to charge controller
  3. Strip end of computer fan and attach to charge controller

Parts:

  1. 10W, 5V Solar Panel:
