Behind the pond.
What are some devices that can have solar panel arrays directly attached to them without the need for batteries/controllers, etc.
Devices that simply run when there is enough sun wattage and shutdown when there is not.

1.Solar water pumps
2.Solar water heaters (dump loads included)
3. ??
 
I run 24V DC server fans in conjunction with DC water pumps for a solar swamp cooler.

Also have a server fan to help RV propane fridge coil circulation. (surprising how much this helps!)
 
There is the next generation of cheap 12V inverters that will shutdown with low voltage and start up again when voltage returns. These will work with a buck converter set to 12V. Be sure to add extra caps on input and output or you will be sorry.
