Select the best area of the ceiling to install a solar tube—preferably the center—and label it. Make a wide enough hole to accommodate the tube by drilling from the ceiling to the roof. Install the dome and flashing after that.

Install the bottom assembly, making sure to include the ceiling fixtures. Attach the extension tubes to the dome and bottom components. Install a diffuser to distribute light throughout the house in an even manner. Make sure the installation is tested to make sure the light is captured by the dome from the sun and directed via the tube to the ceiling, where it is dispersed by the diffusers and lenses.

11 Simple Steps To Install A Solar Tube

1. Know Each Part of Your Solar Tube

Installing solar tubes incorrectly results in less-than-ideal performance. Making a hole in your roof is necessary for mounting a dome. You might get soaked in the leak if you miss this point! Seek extensive advice and establish a well-defined plan to avoid any losses, damages, or future issues.

There are multiple parts to the solar tube that need to be installed by experts. Learn how each component works before you begin mounting your unit. The tubes are quite expensive, and understanding how each component functions would prevent needless breaks.

How then does the sun tube function? Sunlight is captured and directed into the pipes by the normal solar tube’s dome at the top of the roof. A diffuser at the bottom of the tube distributes sunlight evenly throughout your home.

The tube is a long conduit that conducts light from the dome to the diffuser by forming a continuous mirror. Since most units feature flexible tubes, trimming to size is not an issue.

The clear, empty space allows sunlight to enter your home. Even more advanced types use an optic fiber in place of a tube.

Every brand has distinctive components and tenets. Get to know your user manual and read it carefully to learn exactly how to perform a good installation.

Knowing how each component of your solar tube operates can help you install, fix, and maintain it.

This image shows the various components that make up a solar tube. Even though your unit won’t look precisely like this one, you can use this as inspiration for installation.

2. Get The Necessary Tools

Gather the equipment and tools that will facilitate your task. A ladder is first necessary in order to reach the higher areas. When drilling a hole through your roof and into the ceiling, the stepladder will also be useful.

Falling from a height can result in life-threatening injuries or permanent impairments. Hence, purchase step ladders that can support your entire weight. Seeking expert aid is advisable if you reside on the upper floors of an apartment complex or if the roof is too high.

A few tools and equipment to be used during solar tube installation are as follows:

  • Hammer
  • Magnetic compass
  • Torch
  • Plumbline
  • Retaining wire
  • Keyhole saw
  • Reciprocating saw
  • Sealant gun
  • Angle grinder
  • Screwdrivers
  • Drill and bits
  • Scissors or knife
  • Tape measure

It’s easier to install when you have the right tools on hand. Choose between using manual or electric workshop tools based on your level of skill and handymanship.

3. Prioritize Safety Precautions

You should have the necessary tools and an exact installation plan by now. The next action item is to outline your safety precautions.

Any damages or injuries you sustain during the installation process are not covered by the manufacturers’ warranty. The onus of staying safe rests entirely on homeowners or solar installation specialists.

First, think about donning safety gear. A basic hand glove and helmet could prevent a lot of agony and hospital expenses.

Take note of these safety measures as well:

  • When installing the sun tube, you should always have another person nearby.
  • Avoid working on slick surfaces.
  • Install it while the weather is calm and dry.
  • It is not robust enough for the drywall to support your weight. Position a stepladder.
  • The tube’s reflecting qualities may concentrate light or heat in one area under the intense sun. Watch out for flames coming from this radiation’s concentration.

4. Mark The Placement of The Roof and The Ceiling

You should be ready to begin the installation procedure by now. Choose the ideal spot for your solar tube.

Place the dome in a clear area far from any shade. When choosing the appropriate location, take into account the type of ceiling, its length, and the shadow.

Make sure there is no obstruction in the area between the ceiling and roof holes. Next, indicate the locations for your tube’s entry and exit.

5. Drill a Hole Into The Ceiling

Once you’ve ensured the alignment of the spots, it’s crucial to proceed with drilling through the ceiling. Take into account the necessary space required for the solar tube installation. Allocate sufficient room not only for functional aspects but also for enhancing the aesthetic appeal or providing adequate support for the diffuser base.

Ensure the hole is spacious to fit both the diffuser and fixture’s visible house and ceiling features during installation. A snug fit ensures seamless integration, maintaining aesthetic appeal. This meticulous attention to detail guarantees a flawless finish, enhancing the overall ambiance of your space.

6. Make a Hole in The Roof

Equip yourself with your stepladder and drills, ascending to your roof once more. Precision is key: mark your spot meticulously and cut out a hole matching your tube’s diameter, with an added inch for proper flashing. This attention to detail ensures seamless integration and optimal functionality for your roofing system.

7. Put The Top Assembly and Flashing in Place

You must get the top tube and flashing ready before you set the dome. In order to connect the roof end to the bottom assembly using reflecting tubes, you are building the roof end.

Any water or dust will not be able to enter the tube or reach the ceiling thanks to the flashing and roof assembly. Try to seal the hole you made in your roof as much as possible.

For your unit to mount both above and below the roof, it must flash. For example, if the sheets on your roof are galvanized, you will install the flashings at the top and bottom of the sheets. Next, using screws or twists, depending on your unit, secure the flashings.

Using the screws, secure the dome’s ring to the flashing.

8. Position the Dome

You’ve now established a cozy spot for the solar tube roof dome to rest. Tighten the crown into place.

Not all domes face the same direction. Some are slightly skewed.

While some tilts are vertical, others are oriented in the direction of the equator. The unit you’re installing and your location will determine the dome’s angle and flashing from the ceiling hole. Thus, study your handbook or speak with your supplier.

The angle should ideally match your state’s latitude. The dome may face the sun and receive the best radiation all year round thanks to the tilt.

Solar panels in Australia are usually oriented about 30° to the north. The ideal tilt angle in America can be between 28° and 48° south, but you should always check with local authorities or recommendations.

9. Connect Extension Tubes

You now possess both the upper and lower assemblies. It’s time to use extension tubes to connect them.

Start the assembly by removing any protective coverings from the reflecting surface of the tube. There is a wide side and a narrow side to the tubes. Regard these as the ends of the male and female. The bottom assembly should be faced by the narrow end.

Install as many tubes as necessary to join the assemblies at the top and bottom. As recommended by your user manual, use the screws or tapes to modify the angles. To get the right angle, feel free to use retainers to support the extension tubes.

10. Put The Diffuser In Place

The most delicate part of your sun tube system is the final one to install. It’s important to handle the diffuser and effects lenses carefully to avoid breaking or dirtying them.

Therefore, insert the lenses from the bottom assembly until they articulate with the base. The diffuser’s clear section must be facing downward.

While some diffusers rotate clockwise, others must be screwed into place. However, a few of them have smooth joining male-female lugs when they are twisted. To find out the precise procedure your model needs, consult your user manual.

11. Check Your Solar Tube and Fix Any Issues

You’ve successfully finished installing your solar tube, congratulations! It’s time to fix any flaws you may have discovered in your system. Verify that every component of the system is operating as intended.

Verify if the light from your unit is bright enough to illuminate your home as you had originally projected. To compare the two lights during the day, turn off all electric lights and shut the windows. You may wish to increase the number of solar tubes in your lighting system if the light is too low.

In the initial weeks following installation, the device may seem a little dimmer. Dust and humid air can occasionally reflect light away from the light source. Through the flashing insulator, the solar tube will gradually eliminate the pollutants on its own.
