Hi, I need to build a system to power 2 small ceiling fans and a usb charger. The person I am building it for wants it to run by solar only, no battery. 
the USB charger is 12v 8 amps and the fans are 12v 6 watts each. They basically want the availability for their customers to be able to charge their phones and sit under the fans when its sunny out.  what do I exactly need?
Thanks

    Please check your spec's....
    USB is a stand
    ard 5 volts....   
    and 6 watts would be a very low powered ceiling fan...

    I think somewhere you are getting things confused.

    There are 5 volt USB fans,  and some solar roof tiles are 6 volt (nominal)  s well s other 6 volt panels… while you could use a voltage regulator and no battery;

    Something  like this for  each   outlet;  https://www.sparkfun.com/products/107
    Voltage Regulator - 5V

    You might suggest  including a powerbank lithium battery,, for those overcast days;

    I have 6 volt nominal 40 watt solar shingle,  I use to charge a USB power bank.  Sunelec.com  had some assorted larger 6 volt panels, though I didn't find any on their website.

    I built a solar emergency system for my mom in Florida with power  bank,, fan..  This small  8"  fan puts out  pretty good air for the sise.
