Solar powered barn fan?

[RobA]

I have a 10'x10' run in shed for our sheep and want to add a fan to help with the heat and the flies. I'd rather not run electricity to the shed and am looking for a solar powered barn type fan. I've searched online but haven't really seen much. Does anyone know of any?

Amazon I searched solar powered fan. One 12" 3 speed $38 seemed the best deal.

Hope this is right link. 100 sq.ft. should be fine.

Sorry, wrong one. You'll see all by that search, Amazon, eBay, etc.

Have you thought about a wind powered turbine vent? I've used these in the past and found them to be very effective. Requires almost no wind to get a good flow going.

A 12v or 24v DC fan would be best. I assume the RV industry would be the place to start.

SNAP fans are DC powered and can be run directly off a panel IF you only need a fan running when the sun shines. This lowers the cost considerably by taking batteries and charge controller out of the equation. These are very high quality fans made specifically to run off solar.

I have a 16" 3 blade model in one of my small greenhouses wired directly to a solar panel with a thermostat inline so it doesn't run on bright COLD days in the winter. Fan is rated for 24v max, I'm running it on a 100w panel that puts out 18-19v with full sun.

Greenhouse is 12x20 and this fan does a good job moving air. Sun shines, it turns.
