I bought 2 of these fans one to pull in cool air and one to push out the hot. The fans replaced one inefficient fan. I love how quiet they are, and even with 2 running, they are much cheaper to operate than the old fan.

I received this in the mail, it was on time, and everything was in the box and in working order. I was able to install this in my attic with the solar panel on the roof in about an hour total. Very easy set up and it works great. My home is cooler on hot days now. I have a very old home with no A/C so this is very helpful. I may possibly buy another one in order to move more hot air out of the attic and the upper floors of my house.

Buscaba este ventilador para sustituir a uno barato que solo me había costado un tercio. Pero el nuevo no tiene comparación: cuenta con un panel solar de gran calidad y el ventilador en sí está muy bien fabricado. También está muy bien pensado el cable de conexión tan largo que va del ventilador a la célula solar. Esto ofrece posibilidades casi infinitas para montar bien la célula solar... Utilizo el ventilador para un invernadero; la circulación de aire es enormemente potente, incluso con el cielo nublado. Con el antiguo, se paraba por completo de inmediato... El regulador de temperatura también es muy bueno, aunque, por desgracia, no está en grados Celsius, sino en Fahrenheit... pero la conversión es sencilla, por lo que el ventilador se enciende de forma fiable a 25 °C. En resumen, lo recomiendo totalmente.

Easy to install, sufficient hardware., great performance.

L'ho installato nel mio capanno e funziona benissimo.

Best item!!! I trusted other reviews of greenhouse owners and glad I did! Went back and bought a 2nd one

Best solar powered fan I've ever bought.

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.

Questo è il miglior ventilatore solare che abbia mai comprato.

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.
