100 Watt Solar Powered Attic Fan System, Ventilator Gable Roof Vent Fan+100W Solar Panel, for Attic or Greenhouse (DELIVERY in 2 Packages)…

This set up helps to keep our chicken coop cooled down. Everything you need in one purchase. Moves quite a bit of air. I installed a house light switch in the wiring so we could turn off in the winter. I'm going to install a 12V battery so when the sun goes down it will pull cool air into the coop.

There are some things you just should not buy on Amazon. No mounting hardware or bolts included. If you do buy the vent that is shown with the fan it does not fit. The holes do not line up so you have to use a self tapping screw, or some other way to attach the fan to the vent or louver. It should’ve been a simple installation turned into a couple of trips to the hardware store and a pain in the behind.

Works great, good customer service 👍

I purchased a different solar attic fan a year ago from a different seller which is no longer available and it has worked fantastic! Keeps my inside home temp at least 5 degrees cooler. Decided to add one at the other end of the home and chose this solar attic fan. I can't crawl 50 feet through an attic to install on the inside of the vent so I built a 4" deep box and mounted the fan inside the box before mounting to the outside of the attic vent. Worked perfectly doing this and the fan is still protected from the elements. I did wire in an on/off switch so I can easily turn it off during the winter months. Anxious to see if this second solar attic fan makes a difference.

Overall, this seems like a good fan and solar panel - but it is not simply plug and play -- takes a little bit of thought to set it up and configure the wiring correctly. No instructions for installing or connecting the fan to the solar panel were supplied. The panel connections are marked "+" and "-" but the wires coing from the fan are not marked. That wouldn't be a problem, but the end of the solar panel wires that need to connect to the fan wires are left for the customer to finalize with their own additional connectors (male and female bullet connectors - see photo). Since one of the fan wires is black and one is blue, I assumed that the blue would be positive and black negative, which is conventional here in U.S.Everything put together, added a shutter to protect the fan from rain and sun (this one fits, with some extra holes you have to drill yourself, but that's not hard) -- https://www.amazon.com/dp/B08JGBT63V?psc=1&ref=ppx_yo2ov_dt_b_product_details, and tried it out. Alas, the fan was blowing in rather than out (should be an exhaust fan), which does not work with louvered gravity shutters that are only forced to open when the exhaust fan is on and blowing outward. I figure the wires were connected incorrectly, so I redid the connectors and all worked properly. It would have been easier if (a) there were instructions indicating which way to wire for exhaust or intake, or (b) the set had come with appropriate connectors already attached.The solar panel comes with no hardware to attach to a roof (mine is going on an 8' x12' shed which serves as our chicken coop), so I had to order z brackets as well (these seemed good: https://www.amazon.com/dp/B018442ZKQ?psc=1&ref=ppx_yo2ov_dt_b_product_details).Some people add either an on-off switch or a thermostat to allow for cooler sunny days when you might not want the fan to run. I may still do that, but will try it without for a while to see whether it would be an improvement.Update: I did add both a thermostat and a variable speed control because the fan was a bit louder than I wanted it to be, and the positioning of my shed put the solar panel in direct sun all day, which meant it would just always be on. The end result is very satisfactory. The fan is much quieter at about 50% of its capacity, and the thermostat insures that it only comes on when needed.

Purchased for a small greenhouse exhaust. The solar panel and fan are quality made but sourced parts thrown together, it is not out of the box ready, requires additional assembly. Re-reviewing the product images they show for the most part what comes in the boxes (arrives as two part shipment fortifies my thinking they are sourced parts friom disparate vendors shipped to your address) but also a bit misleading need tools and parts not supplied. The fan comes with plastic mounting brackets but no screws (not provided). Fan has two wires with different copper end connectors (shown in the pictures) for some unknown use but not usable with the solar panel cables. Requires cutting off the fan end connectors and stripping wire to use with a compressible wire join connector (not provided). The solar panel comes with two large guage wire cables, one end has male snap connectors into female connectors on the solar panel, the other end just cut wire ends (not shown in the pictures). Requires stripping wires to use with compressible wire join connectors to join solar cables to fan wires. Good I have all the parts and tools at hand for this project. Once the wiring solved I put in the sun and fan runs fast and quiet with good CFM. I plan to keep and improvise an on/off switch in the circuit to allow turning off in the cooler seasons.

I installed it behind a louvered vent on an east facing gable. Outside, you can definitely hear it spin up and down when the clouds go by but not so much inside. Works great.

My solar panel came separately from the fan. I had to go through hell to get the wires and fan themselves. No instructions whatsoever. When I did get my fan and wires, someone put a wire connector on the blue wire. It was the wrong size and I had to cut it off and install one that would accommodate the red wire. The solar panel was the only real part of this purchase. The fan is cheap plastic, no mounting pieces for the fan. I had a small empty plastic bag, I guess the plastic mounting pieces were supposed to be in. Value for the money spent is your paying for the solar panel and get some cheap fan. Performance is poor. Fan motor is not that great. Noise I can deal with as it’s for my chickens. Speed is good as long as suns out and that ok. Overall, I wish the fan had a mounting bracket and blades were made of metal. Definitely will not consider buying another set from this company.
