Nice set of directions.And it is made of a nice ABS plastic to help resist corrosion.A few dimensions on this. Overall diameter, edge to edge, is right at seven inches.

Replace your RV's factory plumbing vent cap with this silent, solar-powered one and get reliable ventilation without the noise or energy loss.


These little solar vet caps Work just fine!
None-the-less, For all my PVC/ plastic roof top covers they fall victim to squirrels! The refrigerator Vent cap alone has been replaced 3 times in about 9 years.


I have installed these vents on two 7'x14' trailers that are used to store kayaking gear (boats, paddles, helmets,PFD's,clothing and other soft goods). Hoping that the constant air-flow will help prevent mold & mildew. I can already feel the difference in temperature (cooler) than prior to installation. They work, but the construction is so lightweight, I'm wary of how long they'll last. For $[XX], it seems they could construct them a little beefier.


We have a Suncast storage building and it was beastly hot inside on sunny days so I put some foam insulation between the inner and outer surfaces and installed 2 of these just below the ridgeline of the roof and they are working great. There is absolutely no noise what-so-ever. While they have a limited volume it takes the hot air out allowing cooler air to enter through the normal vents. Great deal for the money and now we will see how long they last making the value even better.


Installed new vents. No issues so far.


Bought it and still haven’t installed it yet. Maybe next spring.


They work great thank you.


I installed the Ultra-Fab Solar-Powered plumbing vent sold by E-Trailer on my 13 ft. Scamp trailer to circulate and vent air in the trailer while it is being stored. There is indirect sunlight incident to the solar-powered vent that shines through some pine trees. The vent works perfectly. I installed a 4-in. air conditioner duct (sold by etrailer,Valterra Heating And A/C Vent Register) with built in flappers to regulate the air flow thru the solar-powered vent and to make the appearance of the vent look better from the inside of the trailer. Also made a trim ring out of a plastic cutting board to garnish the solar-powered vent inside opening. Look great and works like gang busters.

I had to replace the solar powered vent after one year of service. It was no longer operable. I took the malfunctioning vent apart and found that the seal at the solar panel directly above the motor had failed and permitted water to damage the motor. I installed a second new solar powered vent and took the time to place additional sealant between the solar panel ant its mounting plate.


I am an Rv'er, but actually installed this outlet/exhaust fan on top of my shed. Living in S. Georgia, it gets quite hot and humid, and this thing has been spinning non-stop all year round. I sealed the circumference with all weather silicon as I bolted it down. Outstanding device, and I'll probably get one for my toy hauler as well!

Its been over a year and a half and that little fan is still moving strong, even on overcast days!


Installed this on top of my 8x8 shed for airflow and ventilation purposes. I've had it for a year now and it still runs almost all day. Sunny or even overcast skys will have it humming along. I was concerned with the plastic blades becoming brittle and not being able to withstand the highs and lows of Michigan's climate, but no issues thus far. I recommend this for a solar powered shed roof vent, but cannot give a review as to its intended rv venting capabilities.


I didn't use my solar vent quite as intended. I mounted it into the top of a modified Rv roof vent (which I keep closed typically).

This is a replacement. The first lasted about 5 years but ultimately the plastic degraded in the sun and became brittle. I assume this will do the same over time. We shall see.

Works as intended. Keeps a little air flowing through the rv. Wish there were bigger solar fans for this job.


Seems rather cheaply made…really should have an on/off switch for that price.
Don’t need it running all winter long just because the sun is out but it’s only 60 degrees! (So. Cal.!)
eTrailer was excellent as always though../


I installed this vent on the roof of a 6x12 cargo trailer. It worked well right out of the box, even during a cloudy day. Other reviews suggested adding a screen to keep insects out and so I did. The trailer will sit out in the hot Florida summer sun, and when I return later this year, I'll post an update on how well it performed. So far, so good.


This is the second solar powered vent I have installed in my trailer in one years time. The first one leaked water into the motor located below and adjacent to the circular plastic piece containing the solar panels. I applied additional silicon to the top of the new I just purchased vent where a connection is made between the circular panel and it outer mounting piece. Hopefully this might work.


I used this roof mounted solar powered plumbing vent to exhaust excess heat from an enclosed 5x8 trailer. The inside of the trailer remains somewhat close to ambient temperature


Ordered to replace my worn out solar vent fan. Quick shipping!

A year later and the vent is still performing as expected. Haven’t had an odor in the unit since I installed this vent


I bought this item for a snowmobile trailer to remove heat during the summer. I have yet to install it, but it seems to spin quite fast. I felt it would work a lot better than just one or two plain air vents. Heat builds up fast in a black trailer. I only purchased one, but would recommend two or more for larger trailers. This is solar powered so once it's installed the Sun does all the work...


Runs so quietly that it's hard to tell it's working. But I installed it on the top of my small trailer, where temps had soared to 119 Fahrenheit, and now the temps are much closer to ambient.


seems to work as described. Does take a fairly bright sky to work...but not necessarily direct sun. As an FYI, fan was not on shaft when arrived. After I figured it went on with the embossed arrow showing rotation so that it could be seen, I firmly pushed it on the shaft but it was noisy when spinning. I pulled it back just a tiny bit and it ran noiselessly. Installation went smoothly. I did have to cut about 2 inched off vent pipe so the the fan did not hit the pipe. I also removed the 3 screws to separate the base from top (fan and solar panel) to make the base easier to install then reattached after base was fully installed.


Pros: Well made, good ventilation. Cons: Take a very bright light to make it go. It will only work on a clear day with direct sunlight.

I am amending my review. After further testing I found it does work with overcast skies. 5 stars.


Mixed review, bought two of these, installed them both on my enclosed trailer, to help vent it. One of them stopped working a month later.


Great idea, poor quality. Worked fine for about a month before it began making spinning noises. Obvious that fan was becoming loose on it's axis, possibly from cheaply designed mount. Lasted about another 6 weeks before it stopped working completely.

These should not be a disposable item, and climbing a ladder every 2 1/2 months to change a vent is not an option.

I would NOT reccommend this


We have 4 of these units in service for going on a year now and only one has had any problem. One of the motors had the front end bearing/bushing fail and the unit made a ticking sound when the fan would wobble. The one issue I had a problem with was that when I ordered another to have a spare on hand I found the price had increased from that of last year. While we generally expect that prices will rise over time, having been following solar for a potential solar addition to our home I was otherwise finding that solar was going down in price as the technology was improving so that was a bit of a surprise but overall I believe they are still a good deal for the money.


I put this on my Trailer where i store my scuba equipment, needed to let the moisture out, works great. Will probably order a second one for volume because of the size of the trailer. An added benefit is it functions as a skylight and lets in Light as well.


Found these at the local trailer place, except they were way overpriced!
I replaced the entire roof with metal roofing and these were the only ones that would fit between the ribs.
Haven't installed yet, but the customer service so far has been TOP NOTCH! with extremely quick shipping and great follow up to ensure my satisfaction.
Recommend this site, keep up the great work!


The low profile of the vent met my immediate needs. You cannot hear the fan running so unless I climb up on top it's a matter of faith. You cannot turn it off either. While it may be ideal for a backyard shed it's not a real improvement over a standard rv vent. No regrets on buying it but probably wouldn't buy another.
