What Are The Drawbacks Of Solar Tube Lighting?


A common substitute for conventional skylights is solar tube illumination, called sun tunnels or solar light tubes. These cutting-edge gadgets offer natural lighting without power by capturing sunlight and directing it into interior areas. Yet solar tube lighting has numerous advantages, and it’s also necessary to be aware of its disadvantages. To assist you in making an informed choice, we will examine the drawbacks of solar tube lighting in this post and respond to frequently asked questions.

How do solar tube lightings work?

A system known as solar tube lighting collects sunlight through a dome or lens positioned on the roof transmits it through a reflecting tube, and directs it into a space below. A diffuser or lens at the end of the room diffuses the light, creating a bright, natural lighting source.

What Makes Solar Tube Lighting a Fantastic Skylight Alternative?

Compared to conventional skylights, solar tube illumination offers several benefits. It saves money, is environmentally beneficial, and lessens the need for artificial lighting. It also removes UV radiation risk, gives various architectural options, and may be installed in places where skylights are impractical.

Installing Solar Tube Lighting:

A few crucial actions must be taken to install a solar tube light:

Roof Assessment: Determine whether your roof is suitable for installing solar tubes, ensuring no obstacles or structural problems.

Making a Hole: Make a hole in the roof of the proper size and location for the solar tube.

Connect the reflective tube from the roof to the inside ceiling, ensuring it is aligned correctly and filling in any gaps.

Installation of a Diffuser: Attach the diffuser or lens to the tube’s end inside the space to spread the light evenly.

How soon will I be able to use solar tube lighting at home?

The complexity of the installation, the accessibility of the roof, and the installer’s skill all affect how long it will take to install drawbacks of solar tube lighting. Generally, the action plan can be completed in a day or two, providing instant entry to natural light’s advantages.

Roof leaks – are solar tubes at blame?

When using solar tube illumination, roof leaks are a typical worry. Solar tubes rarely result in roof leaks, nevertheless, when they are fitted properly. To prevent any water infiltration, selecting qualified personnel familiar with the installation procedure is essential, and ensuring the right sealing measures are used.

Do Solar Tubes Increase Room Temperature?

Solar tube lighting does not produce much heat and mostly transmits natural light. However, particularly on warm summer days, the energy from sunshine has the potential to raise the temperature modestly. Modern solar tube systems integrate heat-reduction technologies like reflecting coatings and ventilation options to reduce heat transmission to mitigate this.

Solar tube lighting drawbacks

Limited Light Output: Because solar tube illumination depends on sunshine intensity, it is less effective at night and on overcast or rainy days.

Dependence on Sun Position: The performance of solar tube illumination is influenced by the sun’s position. Rooms with little sun exposure may get less light, which affects the overall illumination.

Solar tube lighting installation restrictions include the need for roof access, which may not be possible in some structures or multi-story buildings.

Space Restrictions: The reflecting tube’s size limits how much light it can transmit, which reduces its efficacy in bigger spaces.

Cost up front: Solar tube lighting can save you money on energy in the long run, but it may cost more to install at first than more conventional lighting solutions.


Any room can have solar tube illumination installed, right?

A: A lot of rooms, as well as the kitchen, bathrooms, and even storage, can be shone by solar tubes.

Do solar tube lights need to be maintained?

In general, solar tube lights require little maintenance. To guarantee optimal light transmission, it is suggested that the dome and diffuser be cleaned regularly.

Can sloped roofs accommodate the installation of solar tube lighting?

Yes, sloped roofs may accommodate solar tube illumination. For proper installation on sloped surfaces, flashing kits that have been specially designed are available.

Are solar tube lights appropriate for all types of climates?

A variety of climates allow for the usage of solar tube lights. However, a region’s access to sunlight may impact its effectiveness.

Are there several solar tube light sizes available?

Solar tube lights come in various sizes to meet lighting requirements. Selecting the right size based on the room size and desired light output is critical.


Solar tube illumination offers several advantages over conventional skylights as an economical and environmentally responsible substitute. However, it’s vital to consider the disadvantages of solar tube lighting, including low light production in poor weather, reliance on the sun’s location, restrictions, restricted installation options, additional space, and upfront expenditures. Solar tube lighting can still offer a useful and sustainable lighting solution for your home or commercial area if you know its limitations and address frequent worries through proper installation and maintenance.
