Easy to install, Instructions were easy to follow. Fan is working great at removing heat from my attic. 1 fan is keeping attic cool enough that my AC is running less often.

PERFECTO, funciona muy bien. extractor de aire caliente para caseta de riego.

Funktioniert tadellos. Benutze zwei Lüfter für Zu- Abluft im Gewächshaus. Lüfter, Solarpanel und Steuerung machen einen wertigen langlebigen Eindruck.

I bought two. I hooked them up to check to see if they worked. They did. I will find a time to install. The Panels are nice, the fan is akin to a car radiator fan. Which is sturdy, heavy plastic. The fan comes with mounting brackets, hardware as does the panels. I think the cable/wire is #10 and is about 12' long. The thermostat MPCC which is what you need to run a Solar/Dc connect direct. One could wire some batteries in series or parallel to charge and run when there is cloud cover or after the sun goes down. One would instead of wiring the fan direct to panel instead put the battery in between the panel and MPCC/ Thermostat then the panel would charge the battery and then run the fan from the battery direct. However, the fan will wear out quicker if you do not have an MPCC to regulate the DC flow. I think they are manufactured well and are a deal at sub $100 range. Now as far as a gable vent application. Realize that air flows with the path of least resistance. So if you have a vented ridge (like I do) and a gable vent, the fan will just pull the nearest air which would be at the ridge vent. FWIW. If your roof is sealed like a dry climate you just tie this up to the Gable vent and exhaust hot air from the attic out the vent. Some argue that the fan is useless since it is radiation that is heating the attic from the sun and blowing the air out is pointless. I think sucking Hot air from the attic and cooling tjhe attic to 110 opposed to 150 will help the Chase/venting deliver cooler air to ducts. I have Styrofoam insulation covering all my Chase/Ducts to avoid the Radiation. This unit is going to be installed in my garage access point to attic, where it will pull cooler air from the garage area into the attic and the ridge vent and gable vent will do their job. The other is for my green house/hoop house. I will have to fabricate some brackets to mount and to put it on a bit of a tilt to chase the evening sun. I think the fan itself eats energy as the sun needed to be bright to drive the fan itself...1300 cfm is pretty good, it is akin to a 20" shop fan on low.

Super Lüfter und macht einen tollen Job!

Bought this on a chance and no regrets. Great item. Battery does not store power, but when the sun is high it's running hard. Works beautifully in our little greenhouse. Ordering our second today.

Picked this up to cool down a shipping container works better than expected!

Its a great fan. I use it in my bee shed to keep my hives cool would recomend to friends.

I bought two of these solar fans to put in my hoophouse. They were easy to install, quality material, arrived fast, and were very affordable. I will definitely be buying some more for the other houses we have.

Works great for moving hot air from my greenhouse! It is actually very quiet also which is nice! I have been using this for about one month now and so far so good…I can’t attest to the longevity of the product yet, though it seems to be well made!
