What is a Sun Tunnel and Solar Tube?


Many homeowners struggle with bringing natural light into rooms that aren't equipped with windows. A solar tunnel is a way to bring natural daylight into lofts or attics. So, what is a Solar Tube? And how does it operate? This page will provide information about solar pipes, also known as sun tunnels, their functions, costs, estimated prices, and other key characteristics.


What is the main difference between a Sun Tunnel, and a Solar Tube?


A sun tunnel is an unpermeable or fixed conduit that runs under the roof and carries light from the outside to a home's interior. The sun tunnel's inner is a highly reflective surface that lets light through from the outside to the room. A diffuser (which spreads light throughout the space) is installed at one end of the ceiling. A transparent cover (roof dome), is then attached to the roof. Sun tubes, sky tubes solar tubes, solar tubes, solar tunnels, and solar tubes are all terms used for sun tunnels.


The radiant interior of the Solar Pipe lets natural light in through. This method of lighting areas is not powered by electricity and is 100% natural.

Because light's natural qualities are light's best attributes, the shorter the tunnel is, the better quality light you'll get in the space.


  • Add a solar tube to your house or sun tunnel


Sun tunnels look very similar to Velux windows. There are no restrictions on how solar tubes or solar tunnels can be installed on roofs. Installing a sun tunnel is similar to installing roof glass. If you are a skilled DIYer you can also install the sun tunnel yourself. It might take some more experience with solar tubes to find the best solar tube.


  • The correct type of solar tube


Which is better: a solar tunnel or a flexible solar tube? This is a tough question to answer since the tunnel type you choose will be determined based on these factors:


  • There is plenty of room in both the room and the roof.

  • Accessibility by using a loft space

  • The ceiling to roof distance is defined as the distance between the ceilings and the roofs.

  • Budgeting.

  • Installation is straightforward

The solar tunnel is strong and can be used for long distances, with no obstacles between the roof of the ceiling and the floor. If your roof orientation is correct, you will get the best rigid solar tube. Stiff solar tunnels provide the best light output if you have a plan for a new structure.

Flexible Solar Tunnels, also called Tubular Skylights, can be used to retrofit loft conversions and other circumstances in which roof space is restricted. Flexible sun tunnels are great for maneuvering around beams and other obstacles. It's essential to ensure the angle of any bends is not too steep, in order to minimize light loss. This kind of solar tunnel is perfect for short distances.


What is the maximum amount of sunlight a sun tunnel can allow?

Sun tunnels should be considered in light intensity. There are many factors that influence how much light you can get in the space. All factors that should be considered include the size of solar tunnels, the orientation, and type of sun tunnels used, as well the roof location.


Many Sacramento solar companies will list the lumen production of their equipment on their marketing materials. These numbers are useless for the average householder. We will instead refer to normal outputs.


Light output from a rigid sunlight tunnel


It is easy to compare different sizes and types to the outputs of standard light bulbs. The most used sizes are the 10" and 14", with an ideal length of 1m. The following light outputs are common:

Expect 150 to 200 watts at the 10 inches and 250 watts at the 14-inch sizes.


It is possible to adjust the output of the solar tunnel light source as necessary.


Expect significant output decreases as the solar tunnel gets longer. When the installation is situated in a non-southward-facing orientation and uses flexible sun tubes 2m in size, you can expect an output of 60 watts to 80 watts.
