What Are The Drawbacks To Solar Tube Lighting (12 Caution You Need To Know)

Statistics show that most homes in America and other nations are now installing solar tube lights in their homes and business places because of the ambiance this artificial lighting gives.

Many skeptics believe that these solar tube lights are too expensive and get the house too hot. These points are not factual and should not keep anyone from enjoying this unit in their homes.

The fact is that these units can be noisy, takes a lot of space, and might not suit all homes. It, however, has a lot of benefits that far outweigh these drawbacks.

What is Solar Tube Lighting?

Solar tube lighting, otherwise known as light tubes, tubular skylights, or sun tunnels, is an innovative and effective way of conveying the lightning from the outside to illuminate the inside of a house that does not get this sunlight direct through the windows or doors.

This unit is engineered by placing highly polished metal tubes which are reflective and can amplify the light from the sun as sun rays pass through them on the roof membrane and the ceiling of your house, through which the sunlight from outside gets into your house with the help of a protruding tube which does not require electricity.

This alternative to skylights and electric lighting is becoming very popular because it is very efficient and is not affected by weather because it has a translucent waterproof dome. They also come in varied sizes, shapes, and colors, and they do not put holes in your pocket.

How Does it Compare To a Skylight?

Both skylights and solar tube light have their selling points and drawbacks, and which one is better than the other is a matter of individual preference. However, they are both good solar energy collectors that will benefit you. Below is a comparison of these two light units.

1. Energy Efficiency

This is simply the amount of solar energy that each unit captures and can disperse to different house areas without losing this light energy.

Skylights are less efficient because even though they accumulate about 3 times the sunlight that an average window can give to a room, most of this energy gets lost as heat in warm weather.

However, this is not the case with solar lights, which disperses almost all the light energy it collects. Hence, solar tubes are more energy efficient.

2. UltraViolet Ray (UV Rays)

Solar tubes have the advantage over skylights regarding the number of ultraviolet rays that get into the house.

This is simply because solar tubes are protected with a weather-proof dome that is acrylic, which helps to keep the sun’s ultraviolet Ray from getting into the house.

Skylights, however, are just placed on the building’s rooftop and only filter and reduce these UV rays. Remember that this UV harms both the skin and the eyes and must be avoided.

3. Aesthetics And Appearance

Skylights look more appealing than solar tube lights because they provide an aura to the home stretch night that feels magical and tends to change the architectural perception of the house.

On the other hand, solar tubes only conduct sunlight inside a building without really changing how you feel about the house.
