Remington Solar30-Watt Solar Attic Fan (BDB) with Thermostat/Humidistat/adapter (20 x 20 x 11 IN.) - Runs at Night - Brushless Motor – Solar Vent Hail and Weather Resistant – “Builder Series

Recently had our roof replaced and chose to update the attic fan in the process. This fan has made an astounding difference in the temperature of our upper level on warm, sunny days. The AC adapter was crucial - on the few days before I got around to plugging it in, the upper level would get hot and stuffy as soon as the sun went down. It's also nearly silent compared to our old one, which is a definite bonus.

This is a very well designed product. The workmanship is very good. The product manual could be a bit better in terms of settings and set up variations. The adaptability to AC power is easy and convenient. The solar panel proved to be very sensitive. As I was ascending the ladder to begin installation the fan received enough solar charge to begin running. After installed, I discovered the thermostat preset at 80 degrees was very quick to shut the fan down. While running it is very quiet. I would have no hesitation in buying it again. I highly recommend this product.

I did a DIY install of this on my 2 story house with asphalt shingles this spring. We live in the pacific northwest with no AC. Our bedrooms upstairs can get mighty hot much in part due to a poorly designed ventilation system in the attic that allows for little airflow from soffits. I've unblocked these to a degree but the static vents just don't evacuate hot air in quantity. I was thinking of going straight solar but I'm glad I didn't. The solar panel is very directional east to west and will only run with near direct sunlight at a minimum. Once it gets to 5pm in the summer it shuts down leaving a still very hot attic. Don't go straight solar with these you will be disappointed.Install: I do a lot of DIY projects and this one is definitely not a super ez install especially if you've got a steep roof high off the ground. I bought a roofers safety harness and rope system ($100 at HD) because one slip up on a high roof and you're done. The video for this product is pretty poor for a DIY instructional. There are others out there but hopefully Remington will step up and make a detailed video to help DIY'rs. I suggest two people for this install will make it a lot easier.. I did it myself and the results were decent but could have been better (didn't line up the unit well with the hole I cut in the roof). Definitely remove a lot of shingles as in rows from 1/3 up the unit to the top then piece them back in being careful to seal properly so you don't end up rain in your attic.It does do a decent job of removing hot air but as I said solar only just doesn't cut it unless you install several at different angles to pickup sun throughout the day.

Really!!! I live in Maui. And this summer was SO Hot! My house is 2 story and the upstairs was claustrophobic with heat! The Home Depot , Lowes, did not and would not order these for me! So, thanks to Amazon! I found them here and they arrived quickly and perfectly packaged. I ordered one for the morning sun and after 1 day, I ordered the other one for the afternoon! Now, I can easily enjoy my upstairs and not be consumed by the heat! The roofer said they were very well made and his install was less than an hour for each one! I am so grateful to have relief! DO NOT hesitate to buy these solar fans ! They work Fantastic!

Good fan, good value, but some issues. I spend more time in my semi-finished storage attic than most people, so I have more detail to share than other people may be able to.The Remington 30 watt solar fan vent uses solar to spin the fan during the day and AC power during the night. Overall I liked it, but there are some issues that need to be addressed.We bought the "Builders Version" that includes AC power adapter. That is important so your vent fan can expel hot afternoon air and also run at night allow cool night air to drift in. You really do want your fans to spin at night.This is a brushless fan motor, a more modern & better motor design. Brushless motors use less power to do more, and is likely to last much longer without maintenance than the old style motors.The fan includes a dangling blue thermostat and only runs if the attic temp is 80ºF or higher. (see attached photo from install video)You'll need to clip a zip tie in order to connect the power adapter cords. And then you need to use more zip ties (not provided) to secure those cables so they don't pull off their solder joints. Remember to have some zip ties on hand.The power adapter is sort of big & sort of heavy, maybe 2 pounds. But the cord from the fan to the power adapter is short. Probably too short for the power adapter to sit on the attic floor and still reach the roof vent. You'll need to mount the power adapter by screwing it into a roof 2x4 before you connect those wires.At night I measured the fan was using 20 watts of AC power, so that seems like a good match with a 30 watt solar PV panel.Some Solar fans include a rechargeable battery, this one does not. My thought was that any rechargeable battery will fail after 3-5 years, and it is unlikely that would be noticed or replaced. I figured with a brushless fan motor, solar power during the day & ac power at night, this unit ought to last a very long time without replacing anything.The instructions say that you must power up the AC power adapter before connecting the solar panel. This is the opposite of what I would expect. Also you must never allow the solar panel to provide power when the AC power is not on(!)This means that an ordinary power outage, or even someone unplugging the power adapter may damage the unit. This seems totally unreasonable and a serious design flaw.Important: you will need to provide AC power to the fan. You'll probably need to get a new outlet installed or run a long extension cord. Consider labeling that cord "Do not disconnect, may damage Remington Solar fan vent if unplugged".When buying a roof fan vent I suggest going much bigger than the ratings suggest. Or getting more fans. This 30 watt solar vent is rated to ventilate 2500 sq feet, my house is about 1200. With an outside temperature of something like 85ºF, the attic temp has been 116ºF even with this fan spinning full speed. I thought I was going 2x big when I bought this fan, but clearly not big enough.I don't know why the fan doesn't cool the attic. Clearly the fan is spinning well & fast. And if you toss some fine dust near the fan, it does get sucked up & out the vent. Even so, I don't feel any breeze at all 1 foot away. Maybe my expectations are unreasonable?I will also say that if you are buying these for someone else to install, go ahead & open the box yourself. You need the serial numbers & papers inside for the warranty, but your installer may throw all that away without reading it. You also want to make sure the installers actually install the power cords and the metal side brackets to aim the solar panel south towards the sun.It seems to me that the hinged side of the panel should face either South or North, which ever will work best to aim the panel towards the sun and allow side bracket adjustment. Without the side brackets installed, the hinged solar panel is free to bang up & down in the wind, which I'm sure isn't good for the glass solar panel.My roofers installed the fan vent facing east (!) with hinge at top edge, and threw away all the paperwork, power cables, hardware & side brackets. Clearly they didn't read any of that either. Luckily I noticed it right away so they were able to dig through their dump truck and retrieve the boxes, papers, & parts. Replacing the power adapters is about $110, so you really don't want those thrown away. It was too late to rotate the solar panel to face south, so my solar panel will forever underperform.While we are talking about roofers, show your roofers the instructions that say that this fan vent should be installed high on the roof, and all the other vents should be low on the roof. No other vents should be within 10 feet of this fan vent. You'd think professional roofers that would know that, or maybe there is some disagreement between roofers & vent makers.Another reason to open the box yourself & read the papers.In closing this fan seems to be mostly good quality build, but my attic is still hot in the summer. So go way bigger than recommended. 2X of ratings was not enough. Electrical design of the power adapters is very suspect. You will need an AC power outlet near the fan. You will need the serial numbers & papers in the box to register the warranty.
