Product Overview

The new solar powered Fresh Air skylight lights up your home and provides proper ventilation using only the power of the sun. It features a solar panel that captures any available daylight and uses it to recharge a highly efficient battery powered operator and control system. The solar panel does not have to be exposed to direct sunlight to function, so it will work on cloudy days and with indirect light.

Customer Questions & Answers

I had a velux solar powered skylight installed today, but as of yet can't get the remote to pair with the skylight.

Do I have to wait for the solar panel to charge in order to power the window, if so how long does that take?There is no mention of this anywhere in the manual, or in the advertising materials.
Asked by: Vesol
There is a very small Off/On switch at the bottom inside of the skylight that needs to be turned on before you start the registration/activation of the remote. The same thing happened to me.

Can the Solar-powered “Fresh Air” Skylight be installed on concrete roof?

Can the Solar-powered “Fresh Air” Skylight be installed on concrete roof?
Asked by: Bobby
Yes, you will need to use the EDW High Profile Flashing Kit, which is used for concrete tile. I hope this is helpful to you. Thank you for choosing VELUX!

can this skylight be installed on flat roof?

and what is the difference between deck mount and curb mount?
Asked by: constantine
No, the VSS Deck Mount Skylight cannot be installed on a flat roof deck. The minimum pitch requirement is 14 degrees (3/12) pitch. You have the option of installing the VCS 4646 Curb Mount Skylight. Our Curb Mount Skylights can be installed on a flat roof application. Simply build your own curb, using a 2x4 or 2x6, and install our unit over it like a lid over a shoe box. I hope this is helpful. Thank you for choosing VELUX!

Can the sash be removed from the inside for someone from the inside to go to the roof ? Or larger opening ?

Can the sash be removed from the inside for someone from the inside to go to the roof ? Or larger opening ?
Asked by: Wai
Per our Technical Department, it is doable, but not recommended. It poses as an awkward situation and the weight of the sash makes it difficult to have control. It is much easier to remove the sash from on top of the roof deck. Thanks!

21 in. x 45-3/4 in. Solar Powered Fresh Air Venting Deck-Mount Skylight with Laminated Low-E3 Glass is rated 4.8 out of 5 by 12.
Rated 5 out of 5 by from So far so good, great addition to room We had a bonus room with no windows and the air was very stagnate. This skylight was a perfect fit to eliminate both conditions. It looks great inside and out and the solar power/rain sensor have worked perfect so far.

Rated 5 out of 5 by from Best product ever!!! I love being able to use my remote to open & close this window. No more cranking the window open with the long pole. The best part is when I forget to close it when it rains it will automatically sense the rain & close itself. One thing I highly recommend is to clean the window well before it's installed. Remove the label reside from the window. Unfortunately my window installers did not do this and I'm stuck looking at this until I can find someone to go on my roof & clean them for me.

Rated 5 out of 5 by from My wife loves it!! I wanted to install a replacement skylight on my home with power type unit so my wife could open an close it easier ,at the time the only one that was available was a hard wired system and that would make it to difficult to do myself . Velux was the answer ,the new solar powered skylight was my answer to my dilemma, I could install it myself without hard wiring it . I ordered it along with the Velux flashing kit through Home Depot online and received it in about a week right to my door . I went online and did my home work and watched the videos that Velux offered . It took me about 8 hrs to install the unit but that's because I had never installed one before , it went smoothly ,the flashing kit made it a breeze . Well we had a hard rain storm 3 days later and it works great with the automatic rain sensor , it closed the window and not a drop of rain got on our kitchen floor. We could never leave our old skylight open if there was even a chance of rain. My wife loves it , she loves the wireless remote (no more cranking) just push a button and it goes up or down . On those hot days when we get home we push a button and within an hr the house cools down 5-10 deg and saves on air conditioning. I would highly recommend these solar units, I'm sure it will pay for itself in the long run just in the savings on AC usage

Rated 4 out of 5 by from Great product, looks great. It's a great looking skylight and works good too. It is a little loud opening and shutting but that's not too bad. The control panel is cool and looks nice on the wall. The item does not come with flashing which is necessary to install it. Not being aware of this we had to place a separate order and wait to have the installation completed which was a bit of a pain.

Rated 5 out of 5 by from I love this skylight! I can't really talk about the ease of installation because my contractor did it. But I have had it for a year now and it doesn't leak. The remote control is very cool and I love how no electricity is required at all. Just cut a hole, install with flashing and patch the roof. It works like a charm and has totally transformed a dark bathroom. I am putting another one in my kitchen and a third in another dark bathroom. Very highly recommend this skylight.

Rated 5 out of 5 by from Loved the 30% tax credit Considering the 30% tax credit this seemed like a very good value. Remote set up very easy other than the instructions should have mentioned the On/Off switch on the skylight that must be on to activate the remote before beginning.

Rated 5 out of 5 by from Great skylight Framed the r.o. and it fit like a glove. Operation was very easy and the remotes work from the basement to the 3rd floor w/ no problem.

Rated 5 out of 5 by from Cool Skylights! These skylights transformed the room. I can't imagine why anyone would install those opaque plastic bubbles when these are available. We had a contractor install and I don't think he had any problems except the instructions for the blinds were useless -- a few pictures -- had to scour the internet for videos. The blinds were not difficult to install once it was clear how to do so. These things close as soon as it starts raining and the remote control is very easy to use and basically auto-configures itself. There are lots of features with the control that we haven't explored.
