Product Overview

A smart alternative to conventional roof vents, the Solar Powered Attic Vent operates during the day and collects power from the sun to convert into electricity. In turn, this energy operates a high efficiency motor inside the power vent, so there's no added cost for electricity. That saves energy, which is better for the environment. Cools your home in the summer and removes harmful moisture in the winter.
  • Lowers your energy costs from attic temperatures that can exceed 160°F heating up air condition ducting and radiating heat into your home forcing your air conditioning to work harder

  • 1820 CFM's
  • Solar panel tilts and rotates for maximum sun exposure

The fan arrived in good condition. The base was a little bent, but it was easy to bend it straight by hand. There really isn't any assembly to the fan. You only need to connect the wires together when you are ready to install it and adjust the angle of the solar panel once positioned on the roof. Installation is pretty straight forward. You will need the following: hand drill, jig saw or sawzall, maker, hammier, roofing nails, utility knife or heavy duty shears, caulk/silicone, and caulking gun. The instructions are pretty basic, but there is nothing really complicated about it. It can be done by one person, but 2 people would be more convenient. One note on the installation: The instructions say to cover the solar panel with its protective cover once you connect its wires so the fan isn't running while you are installing it. There was no protective cover included, so make sure you save a piece of cardboard from the box to tape on it until you are done. What I like: Its solar powered so you don't have to mess with wiring it into the house. You can adjust the solar panel based on your roof, relative to the sun. Its quiet - see the video with sound. What I don't like: The panel attaches to the top of the fan by 3 wing nuts. Rather than the bolts running through actual holes on the mounting plate, only the edges of the wing nuts overlay onto the mounting plate. This makes the initial positioning of the panel very easy as you can just spin it around, but I don't feel its very secure with only 3 little lips of metal holding it on. To make that worse, given its position on my roof, the panel needed to be adjusted almost all the way upright. That means it can catch wind well and I worry that a strong gust will be too much for those 3 little attachment points. There is a plastic mesh covering the air opening but its not sealed on the top. A squirrel or chipmunk could easily push its way in. I would recommend sealing it with a line of caulk or silicone. Overall I think its an OK fan, but some slight modifications would make it better.

This is a really good product. Very quiet and very easy to install. My issues are with US Sunlight customer service and the installation instructions. They need to update the instructions because it's very confusing. It says "Position and install the controller". There is no controller included with the fan. I thought it was just left out so I checked the 2nd fan that I bought and it's also missing the controller. I called US Sunlight CS and this rude woman said she this model does not come with a controller. I said but the instructions inside and outside the box mentions the controller. She said I don't know why you're looking for something that's not there. This model is solar and the sun controls when it comes on and off. The dome was dented because the wingnut that holds the solar panel to it came off while inside the box. I disassembled the unit and pounded the dents out.

      Received in good condition. I like that the solar panel is fully adjustable both up and down but also swivels to set it in the optimum position. It moves air, but I doubt it moves 1820 CFM, even at optimum panel angle to the sun. There's no thermostat so when the sun's up, it runs. I got 2, one if which is a little noisy when it runs.

      It hardly runs a few hours a day, with all day sun. You will rarely get max cfm. For almost $400.00 I thought it might have a little capacitance. But it won't run after dark.Regardless, I would not buy again or recommend. They just want to sell you their $139.00 solar control for running it all the time. Also bug screen is cheap and keeps hitting the fan blade. Had to modify it's shape.
