Frige Fan?

That is good info to know about the solar fan.

If one would use the guts of a solar security light, they seem to be pretty good (I have some working for several years). They have some buffer batteries, and could thus handle some clouds. I think they run on 6 volts. What voltage do muffin fans have?

If you are talking about this setup from Camco Clicky dont waste your money. I bought 2 of them dirt cheap and I am glad I never paid 90 bucks for them. The solar panels are complete garbage. The first one turned yellow and starting cracking within 2 months and then just didnt work. I replaced it with the second one I had and the same thing happen. I wrote Camco because a solar panel should be made to be outside but they could have cared less.

Needless to say I would never reccomend them to anyone. Buy your own quality small panel and make it yourself instead.

I really like the idea though. It would make a great item to hook to the dump load of a solar controller, or build a quality set up with a small dedicated solar panel. As long as the fridge does not need the fan to operate and it is just there to increase efficiency, using direct solar to run the motor is a great idea. If you computed the increased efficiency of not storing solar energy in the batteries then taking it out, and added in the increased efficiency of the fridge, it could be one of the most efficient/fastest payback solar systems you can install on an RV.

Does the fan speed on these type of muffin fans vary with amps available? Say if you give it 30 % of it's desired current, will it just run slower without damage?

Different subject than the OP but since you asked;
You may not need fans at the rear, the most common problem is poor installation. It can often be solved by adding baffles to direct the air flow where it belongs.

Study these pictures and see if yours is installed correctly and how to modify your installation.

I installed fans and baffles in my pop up. I may take the fans back out because it appears they are unnecessary and I seldom run them. The baffles are the way to go.

Thanks for the link. I have to look at my unit once the weather gets a little warmer. With our current condition I could use the fridge as a heater, cause it will never reach the single digit (or lower temps) we currently have.

I have a "Valterra FridgeCool" fan mounted in the vent at the top of my fridge vent stack. It's thermostatically operated, and makes a noticeable difference in hot weather.

Thanks, that seems to be a good idea.

I've seen too many overcast days and dark nights when it was still plenty hot enough to affect the fridge to want to rely on solar to power the fans.

Hudsoner,
I installed 3 computer fans on a homemade frame at the top of the reefer stack to exhaust the heat.
The reefer is ion the rear wall of the fifth and gets a lot of sun.
12 volt power is available at the rear of the reefer or as I did run them off solar panels on the roof.
