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 standard 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
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.

Uses 4 watts at full power here's picture for scale next to a l0,000mah power bank and phone;
Home system 4000 watt (Evergreen) array standing, with 2 Midnite Classic Lites, Midnite E-panel, Magnum MS4024, Prosine 1800(now backup) and Exeltech 1100(former backup...lol), 660 ah 24v Forklift battery(now 10 years old). Off grid for 20 years (if I include 8 months on a bicycle).
- Assorted other systems, pieces and to many panels in the closet to not do more projects.
