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

This fan works well, but we had to install a speed controller to lower the speed during full sun. At full speed it is very loud and a little obnoxious. With the speed controller installed, it works great

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.

The fan arrived without the solar panel. Unknown how to get the panel. The solar panel arrived 3 days later. The wiring on the fan has a receptor to plug in the wiring from the solar panel but the solar panel arrived without compatible plug at the end of the wires. The wires are short and you will need to add additional wiring to make the wires longer. The set up For the non-electrician. The solar panel does not hold any residual power. As soon as you walk in front of the solar panel the fan stops blowing. This is very different from other solar panels I’ve used. I’m very disappointed and I will be returning this item.

It came on time and was as described. It was easy to put together, required no extra parts.

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.

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.

Purchase arrived two days ahead of schedule. Mounted and wired system up and it has made a big difference in my homes temp. It only runs during the day as there is no battery to store power. Doesn’t seem to be a problem though. Also wired a temp switch to limit fan on cooler days. I recommend this product. Solar is the way to go for attic fans. Why waste energy to save energy? Zero cost after initial purchase. Happy with this choice.

This works well. The wiring is confusing at first. The two ends that come off the fan accept the two exposed silver ends. I had to pry one of them open. For the exposed silver wire to fit. Wrap the connection with electrical tape. Connect the solar ends from the solar panel. To the red and black wire. It works well, and only works when it's getting sun. The only negative review. Is it needs an on/off switch. I'll add that no problem. Just installed it. The longevity of it I do not know.
