Connecting solar panels to a battery-operated mini fan

  1. Jul 5, 2009 #1
    Is it possible to connect solar panels to a mini hand held fan and making it run on both rechargeable batteries and solar panels? i'm sorry if it's vague. i need to make a hand held fan that runs automatically on solar panels (when there's sun) and on its rechargeable batteries (when there's no sun haha!) it needs to be all built in. my worries are on the wirings. is it doable? can the panels still charge the batteries when it's running(turned on)?

    wait, can i even change the source from disposable batteries to rechargeable batteries(like those covered batteries in cordless phones)? or can i put rechargeable batteries(normal looking ones available in the market) directly on the fan and would it be recharged there?

    How can i make this thing work??? please help me. i need it for my physics project. :(

    Go to the www.instructables.com website and do a search on "solar". There are all sorts of DIY solar projects listed that should get you headed in the right direction. Also Forest Mims "Electronic Sensor Circuits and Projects" Volume 3 has a section on Solar cell projects. There is a ton of solar circuits on the web, start searching.
