Solar light roofs have been around for decades, but they're still a relatively new concept for many homeowners. They can be installed on top of existing roofs or built into new constructions.

With a solar light roof, you can harness natural light during the day and reduce your reliance on artificial lighting. This can lead to significant energy savings and a more sustainable living space.

Solar light roofs work by using photovoltaic cells to convert sunlight into electricity, which powers the LED lights embedded in the roofing material. These lights can be adjusted to different brightness levels and colors to suit your preferences.

The benefits of solar light roofs are numerous, including reduced energy bills, increased property value, and a more eco-friendly living space.

What Is a Solar Light Roof

Solar roof lights are a type of renewable energy-powered lighting solution that sits in the ceiling of structures.

They use solar energy to charge a battery during the day, which then produces light once it's dark.

Solar roof lights often come with motion sensors that trigger them to light up for a short period of time, and can be reactivated if needed.

These energy- and cost-efficient lighting solutions are ideal for mobile structures, as they don't require a mains connection.

There's little to no maintenance involved with solar roof lights, since the battery is recharged automatically.

How It Works

A solar tube is a 10- or 14-inch-diameter sheet-metal tube with a polished interior that acts as a continuous mirror, channeling light along its entire length while preserving the light’s intensity.

The interior of the tube captures daylight at the roof and delivers it inside your home, making it a great option for homes with limited natural light. The effect is dramatic, with new installations often having homeowners reaching for the light switch as they leave a room.

Solar tube heads are optically engineered to direct as much light as possible into the tunnel below, and they come in a variety of sizes ranging from about 1 to 2 feet in diameter.

A solar tube, also known as a sun tube or light tube, is a sheet-metal tube with a polished interior that acts as a continuous mirror, channeling light along its entire length.

It's usually 10- or 14-inch-diameter, and captures daylight at the roof to deliver it inside your home.

The solar tube head is optically engineered to direct as much light as possible into the tunnel below, and comes in a variety of sizes ranging from about 1 to 2 feet in diameter.

A clear, weather-resistant acrylic dome protects the tube head from the elements.

The tube skylight piping length can be extended indefinitely, and is lined with a super-reflective coating to amplify the direct sunlight as it pours through to its target.

This means you can get light from the roof to the room below, even if it's on the opposite side of the house.

Most models come with a low-profile, flexible tubing that makes installation easier, as you don't need to cut and fit sheet metal like you would with rigid solar tube models.

A UV ray protection system is usually included, either at the source of sunlight on your roof or in the light diffuser at the end of the tube, to prevent adverse health effects or damage to paintings or surfaces.

Solar light roofs are also very effective, with a working time of over 500 cycles after one full charge. Each cycle lasts 30-45 seconds, providing reliable lighting for a long time.

Here are some key benefits and savings of solar light roofs:

  • Cost-effective: The initial investment for solar light roofs is low, and ongoing costs are non-existent.
  • No maintenance: Once installed, solar light roofs don't require any maintenance or associated costs.
  • Easy installation: Solar light roof installation is simple, quick, and doesn't require expert assistance unless requested.
  • Green energy: Solar light roofs use renewable energy to power them, making them extremely green and having a low environmental impact.

Solar light roofs also offer a lot of savings, especially when compared to traditional lighting solutions. They can help reduce your electricity bill and your carbon footprint.

Installation and Ease

Installing solar roof lights is a breeze, taking just 5 minutes with or without professional help.

A Solareye solar powered roof light is a great example of this, requiring only a small 83mm hole for installation.

The process is straightforward, with the light secured using adhesive, screws, or rivets to ensure a watertight seal.

A rubber washer is used to prevent any rain from entering the structure.

Solar tube installation is also relatively fast and simple, thanks to their small footprint.

They can be easily plopped into your roof, between rafters.

In contrast, installing skylights is a more laborious task that requires careful consideration of roof structure integrity.

A large window is embedded into your roofing membrane, making it a more complex process.

Comparison with Skylights

Solar tubes are a cost-effective alternative to traditional skylights, with a price tag of around $750 apiece compared to $1500 to $2500 for skylights. This significant price difference makes solar tubes an attractive option for homeowners on a budget.

However, skylights do offer a more immersive experience of the outdoors, especially if you have a vaulted ceiling to embed them in. Solar tubes just can't compete with that.

For homes with a lot of attic space, solar tubes are a practical solution that can save you money by avoiding the need for expensive header beams and drywall. By piping sunlight through a solar tube, you can achieve a similar lighting effect at a fraction of the cost.

Benefits of Skylights on Health

Having a skylight in your home can be a game-changer for your health. According to the National Institutes of Health, 42% of Americans are deficient in Vitamin D.

Every extra photon of natural sunlight in your home is an additional resource your skin can use to create more Vitamin D. This helps boost your immune system, mood, and musculoskeletal health.

Being in an environment with more sunlight can ease symptoms of depression, increase your energy, and help you feel better about yourself.

Cost of Traditional Skylights

In terms of cost, solar tubes are often less expensive to install than skylights, especially for smaller spaces. However, skylights can be more aesthetically pleasing and may be worth the extra cost for some homeowners.

Solar tubes have a more limited view than skylights, as they rely on a reflective tube to direct sunlight into the room. This means that skylights often provide a more direct view of the outside, which can be a major advantage for some homeowners.

In terms of maintenance, solar tubes are often easier to clean and maintain than skylights, as they don't have a glass surface that can be prone to streaks and water spots.

Skylight Pros vs Cons

Solareye roof lights have some advantages over traditional skylights. They're portable, so you can install them anywhere without needing a mains connection.

One of the biggest benefits of Solareye roof lights is their long-lasting batteries, which can last 8+ years. This means you won't have to worry about replacing batteries anytime soon.

Solareye roof lights are also incredibly durable, made from high-impact engineering grade polymer that can withstand temperatures ranging from -20c to 70c. I've seen them work just fine in some pretty harsh weather conditions.

Here are some key differences between Solareye roof lights and traditional skylights:

Solareye roof lights are also very cost-effective, with a low initial investment and no ongoing costs. They're essentially maintenance-free, which is a big plus.

Skylight vs Cons

Skylights are the clear winner when it comes to taking in the view. They allow you to more fully experience the glory of our natural surroundings than solar tubes will, especially if you have a vaulted ceiling to embed them in.

Solar tubes can't compete with skylights in terms of visual impact. They just can't match the experience of having a direct view of the sky.

However, solar tubes have a significant cost advantage. They can be installed at a fraction of the cost of skylights, making them a more practical choice for many homeowners.

Skylights require expensive header beams, new drywall, and other costly materials to install. This can add up quickly, making them a less affordable option.

Overall, if you're looking for a more affordable solution, solar tubes are worth considering. But if you want to take in the view, skylights are the way to go.
