Solar tube skylights have various names, including sun tunnels, tubular skylights, and sola beams, some of which are trade names. These skylights are designed to maximise the amount of light entering a specific area, despite their relatively small size. They consist of a transparent top on the roof, a reflective duct that channels light to the ceiling level of a room, and a diffuser that disperses the light while concealing the duct.
Most solar tubes are round on the roof, although some are square with round ducts and round diffusers on the ceiling. The round tops (domes) are typically made of perspex or acrylic.
Solar tubes are considered entry-level skylights compared to conventional types. They are cost-effective to supply and install, making them an attractive alternative to more professional systems. The manufacturing process is also cost-effective, using significantly less material than conventional skylights and allowing for quick installation into a roof and ceiling. Solar tubes effectively bring natural light into areas that lack sufficient natural light.
A professional solar tube, like Skybright Skylights’ proprietary Sola Beams, can be up to a third cheaper than installing a traditional skylight with boxing.

Solar tubes effectively bring natural light into areas that lack sufficient natural light.
Solar tube skylights bring in natural light but not direct sunlight due to the diffuser at the ceiling level. However, the amount of light can be almost the same as that of a normal skylight, depending on the size of the units and the depth of the tunnel.
Most modern homes lack natural light, and installing a skylight is one way to address this issue. Skylights, especially solar tubes, have a profound impact on our mental and physical well-being. They can improve moods and energy levels, reduce depression, and help with vitamin D production, which is crucial for the immune system and bone health. Morning light boosts cognitive performance and focus. Sunlight affects the circadian rhythm, influencing the production of melatonin.
Exposure to morning light enhances circadian rhythms, helping to wake up and maintain a healthy sleep schedule. Natural light is essential for eye health. A well-lit home feels warmer, and studies have shown that children studying under natural light achieve 20-30% better results in exams. Skylights also reduce electricity usage, making them energy efficient.
Unfortunately, no. The quality of solar tubes vary. You can find imported units that look good and are well-made, but they may not withstand the harsh South African climate, particularly the high levels of ultraviolet light. Locally made units may be manufactured as cheaply as possible using low-quality materials that do not last.
Poorly designed systems can perform badly once installed, as they may not be designed for different roof types. If a skylight’s price seems too good to be true, consider the quality of the unit, installation, and guarantees.
The plastic acrylic tops can fade and become whitish after a few years, reducing the amount of light passing through the dome. Highly reflective ducts, designed to maximise light, can create a glaring effect when the sun shines directly onto the duct. Smaller units may not let in enough light, especially on cloudy or overcast days. Outdoor light is always better than indoor light, and larger units generally perform better.
Thin domes or acrylic tops can be damaged by hailstorms. Flexi ducts that are not UV stable can crumble over time due to exposure. Many sola skylight companies do not sell spare parts, and different styles from various manufacturers are not interchangeable. It’s important to remember the make and model number of your skylight.
Most solar tube skylights, like sola beams, are available in 300mm, 450mm, 600mm, and 700mm round systems.
There are a few leading manufacturers, including Skybright Skylights, a member of the Skylight Association of South Africa. They produce various skylight systems, including their proprietary sola beam systems (solar tubes). They have made several improvements to the solar tube skylight system for the South African market, such as:
Standard Sizes Include:
Custom sizes can also be made, which are cost-efficient when fitting between rafters. Larger units can be very cost-effective.
If you are unsure about the sizes and need more information or a professional sola beam installer, you can request a quote online from Skybright Skylights.
Some companies offer a 1-year warranty, but Skybright Skylights provides a 5-year guarantee on their solar tube/sola beam units.
Sola beams are suitable for roofs with pitches greater than 20 degrees but are not ideal for flat roofs. For flat roofs, a conventional pyramid or sloped skylight with minimal boxing is recommended.
As technology continues to advance, we can expect solar tubes to become even more efficient and versatile. Innovations in materials and design will likely lead to increased light output and easier installation processes. Additionally, the integration of smart home technology could allow homeowners to control and optimise their solar tube systems more effectively.
The environmental benefits of solar tubes will continue to be a driving factor in their popularity. As more people seek to reduce their carbon footprint and live sustainably, the demand for energy-efficient solutions like solar tubes will grow. By harnessing natural light, solar tubes offer a simple yet powerful way to contribute to environmental conservation.
The market for solar tubes is expected to expand as more homeowners and builders recognise their benefits. Increased awareness and availability of solar tube products will likely lead to broader adoption. Manufacturers like Skybright Skylights will continue to lead the way with innovative designs and features that meet the evolving needs of consumers.
Solar tubes are an elegant, efficient, and affordable solution for bringing natural light into dark areas of your home. They offer numerous benefits, including cost savings, energy efficiency, low maintenance, and positive environmental and health impacts. While they may not provide the expansive views of traditional skylights, their practical advantages make them an excellent choice for many homeowners.
By carefully selecting the right solar tube models and features for your home, you can enjoy all these benefits and more. Whether you’re looking to brighten a dark hallway, bathroom, or any other dim interior area, solar tubes are a versatile and valuable investment. Embrace the future of natural lighting and enhance your living space with the simple yet powerful addition of solar tubes in 2024.
