4 fans 1 pannel?

[wine_guyu_3]

Hi,
I have several solar powered attic fans that I am using to circulate the air inside the cabin (prevent mold)
Each fan has its own panel; about 10 watts each.

I'm going to run DC outlet boxes around the inside of the house so I can just plug the fans in, or move them.
Can I just run all of them from a single 100 watt panel?
Would that fry the motors?

Thanks for the feedback

A 100W panel can go to 20V with only a 30W load. You can buy a buck converter to limit it to 12V. If demand is greater than what the panel can produce, voltage goes into a death spiral. So, low light level performance will suffer. Fan probably won't be needed at those times.

A buck converter at the fan could also efficiently allow setting
a variable, constant fan speed, and allow more fans to
operate at lower settings. But if the load reaches the power
limit available at that moment, the voltage will collapse.
