I haven found that a 20W multi-crystalline PV panel can be coupled to quite a collection of surplus muffin fans. I recently acquired some muffin fans that move 120CFM while consuming 6W, and I am able to run 3 fans off one 20W PV panel. Works fine if you're home when it is sunny, but what if you work?
Put a 12V charge controller on the panel, charge a 12V 5Ah battery. Now you can run the system after the sun goes down. If you use a charge controller with a low voltage cut-off, your drier will stop before it damages the battery. I realize the 5Ah battery is rather small for the 20W panel, but you can parallel the batteries for more storage capacity, especially if you don't run the system daily.
