Remington Solar "Builder Series" 30 Watt Solar Attic Fan - Includes 110V adapter for auto-run night time operation

I’m very handy when it comes to remodeling houses but I have never cut a hole in the roof to install a new fixture. The install was surprisingly easy after watching a couple YT videos.I started the project by taking a large piece of paper and pressing around the diameter of the fan bottom so I could mark a template on the room. After using an scissor to cut out the circle I got up on the roof and used a sharpie to mark the spot after finding where the roof trusses run. I have an asphalt shingle roof. I used a stud detector and ran across the roof to find where the trusses are. I marked the circle then used a reciprocating saw to carefully start a hole away from the center then pushed the blade all the way into the roof and used it like a jigsaw. The circle cut perfect and quick using this method. With the hole cut I used the saw to cut the nails under the shingles around the entire hole to make them free to slide the fan flashing metal under. I put a couple rings of outdoor rated silicone caulk on the bottom of the fan then slid the fan under the shingles with only the bottom portion above the shingles. I use 5 screws provided to secure the fan through the metal. You can use more but you likely have to pre drill holes through the metal. I then caulked the screws and under all the nearby shingles. I did put some tar where the fan meets the shingles for even more protection. Running power in the attic was a breeze after tapping into another receptacle and adding a receptacle a couple feet away with 14/2 wire. Really easy install. BTW I call the fan durable because I left the fan on the roof and ran to grab some tools and the fan slid down the roof and fell 10 feet on the grass. It was scuffed up and the metal bent slightly on the bottom but worked perfect. Hopefully my attic won’t be 150 degrees anymore!

This solar fan has saved me soooooo much money! Only cost about $200 to professionally install. Immediately starts working. I didn’t know that it also requires a hardwire electrical connection to turn it on or off so when installing, I gave the guy a 50’ outdoor extension cord- well, that is apparently permanent now and I had to install a switch in the attic to connect it to….

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.

I purchased this to replace a 15 year old attic fan in my office, which is located in an attic space above my garage. This is both more powerful and quieter than my old fan. The electrical override kicks in at 72.5 degrees F, according to the little thermometer I bought. Sometimes the fan cools the space down a little too much! I had my old fan plugged into a switch so I could shut it off during Zoom meetings or when I wasn't in the office. I have not done that with the new fan since it would void the warranty. If I purchased the Wi-Fi add-on, I believe I would be able to turn the fan off and on, but I'm discouraged by the poor reviews of the accompanying phone app.With my old fan, I considered it a success when the temperature in the office was the same as the outdoors with the air conditioning running downstairs. On a recent 95 degree F day here in the Seattle area, with my windows closed and the air conditioning on downstairs, the temperature never got above about 82 degrees in my office. I am very pleased.

Solar panel is way undersized, you can easily see this by putting it in full sun and then put you palm over just 2-3 inches of the solar panel, and it will come to stop. Same thing happens with clouds, obviously.Main issue I have is it does not deliver anywhere near promised CFM. Used this to replace my 12-year-old model from another company which is still half the price of this one today, that old model had more CFM and had a swivel solar panel so it worked on solar hours longer. I really wanted this American made product with great warranty to deliver. It just did not.I measured the CFM while on solar and direct/full sun, I only get around 450 CFM. Once plugged into outlet, it goes up to about 650 CFM (still less than half advertised). Compared to my old brand which had lower CFM specs but delivered twice what this one does. My measuring of CFM/airflow is not perfect, but I used same tools to measure my A/C fan it and it calculated out to 90% of manufacturer spec, so measurements are not that far off.At 650 CFM, it does not provide enough airflow to do much. My attic is still 35-40 degrees hotter than ambient temp. This is with plenty of gable vents and this attic fan being bigger in specs than the recommended size for my house.
