RecPro RV Solar Ventilation Fan | Solar Powered Ceiling Vent with Fan | For RV, Marine, Camper, Shed, Trailer (Black)

I put this solar vent fan on the front top of this west-facing storage shed in the picture. This morning at 9:30, with the sun behind clouds and over to the south east of the sky, the solar fan was spinning like a champ - without any direct sunlight on it. I’m not sure why other reviewers are saying it only works in direct sunlight; absolutely not my experience. I sealed up all the openings on this shed and then cut two 4x4” ports on the bottom back wall of the shed, which I covered with fine mesh screen. The vent fan is completely venting the air in the shed. Very good product.

I put this on my uninsulated work van, and it makes a world of difference after being parked for a few hours. It's nearly silent, simple to install (USE SEALANT), and moves enough air to make a difference.

This does move the air that is need to exhaust fumes from the tank also does not work well under a roof where direct sunlight is available. They need to tell you the cfm witch I don’t think they can measure it it moves that little of air it took me a while to install it but was in Florida where there is a lot of sun

Works great

This works great during the day with sunlight. Doesn’t work without sunlight. I wish it had batteries to charge up for nighttime use. The installation was easy. Removing the old dicor was the hardest part. Super quite.

It lasted about 2 years in the daily sun until it completely disintegrated and came apart.

These are a must to pull away the smell from the holding tanks on any RV. We have installed on both a Class C and a 5th wheel. They have a tiny solar powered fan that runs rather than the caps the factory usually installs. The fan aides in pulling that rancid air out of your system and away from the home on wheels.

I love this vent fan. The only bad thing is NO SUN LIGHT NO FAN. I’M THINKING OF RUNNING A 12volt wire from my exhaust fan over to it with loom to it with a s/w in the exhaust fan area.

its noisy and wish it had a battery

It only works in direct sunlight. If it's overcast on a summer's day, or if this is pointed off to the side of a building, so not in shade per se, but not in direct sunlight, the fan does not spin. It also produces a high pitched wine at slower speeds, which can be annoying. If you are putting this directly on a roof, and stay out of the shade, then it works very well. Mine also came a little askew. I had to unscrew the top and set it properly.

J'ai du ajouter une thermoswitch car le moteur étant branché directement au paneau il force lorsque pas tout à fais asser de soleil. Avec une thermoswitch qui ouvre a 40°c jme dit quil va faire soleil. Bref à suivre je ferai un autre avis si je brule le moteur.

Doesn't work very well, you can hardly notice the air movement.

No amount of sun light will make it spin
