Solatube: 30 Years In The Making

The evolution of skylights


Over these past three decades, the world has experienced building booms and busts, energy crises, brownouts and blackouts, all leading toward a shift to sustainability and a realization that more natural light indoors is better for the well-being of humans and the planet. And through it all, Solatube International Inc. has been leading the charge, relentlessly innovating and improving its products and their performance to help conserve resources and protect the environment for a better future. Brightening over two million homes, schools, stores, hospitals, offices and other facilities in over 100 countries, Solatube comes back to its roots to review how an idea from three young entrepreneurs evolved into cutting-edge daylighting products that continue to deliver energy-efficient solutions that inspire and shine pure, natural light in residential and commercial spaces across the world.


It all started 30 years ago by three dreamers from Down Under who had the radical concept of capturing sunlight from a roof and transferring it into a dark home. Little did these budding entrepreneurs know that their new product innovation would address a massive void in the building industry, soon becoming a worldwide phenomenon. For years the trio of visionaries pulled their resources together to produce technical drawings and develop launch materials for the new product idea, and in July of 1991, Solatube International Inc. officially opened in Australia, selling only one product, the Solatube 250 residential tubular skylight (or 10-inch unit).

“Soon after launching the Solatube 250 unit, the Solatube tubular skylight quickly became the best-selling skylight in Australia,” said Solatube International President Robert E. Westfall, Jr. “By 1992, co-founder David Rillie understood the potential for dramatic growth in North America and ventured to Carlsbad, Calif. to establish the first U.S. office.”


With only four employees and 7,500 square feet of space, Rillie and his team in the United States explored several more innovations, including add-on features and a larger unit. These developments helped Solatube Australia open its first retail store in South Africa and establish the first Solatube International distributor in New Zealand.

“From there, Solatube’s popularity continued to spread across the global market, and over the next decade, we coined the category name Tubular Daylighting Device, or TDD,” added Westfall. “This helped create a new segment in the building industry which led to developing and supporting new codes and standards for building safety and energy conservation.”

Eventually, Solatube outgrew its first U.S. office, and in 1999, the organization moved to its current 57,000-square-foot international headquarters in Vista, Calif.

Continuing to earn its reputation as the market innovator, Solatube invested heavily in product development and over the next decade introduced an enhanced residential line featuring its patented Raybender® technology and Spectralight® Infinity Tubing, residential decorative fixtures, the Solar Star (a residential solar-powered attic fan), the SolaMaster series (a 21-inch commercial daylighting system) and the ground-breaking 29-inch commercial SkyVault series.

Additionally, Solatube continued to expand worldwide, with new global distributors throughout Europe, Russia, Central and South America, Africa and Asia. With the global expansion and a strong product line, Solatube had set its foundation.

“Thirty years of innovations, collaborative dealers and distributors, committed employees and visionary leadership have created Solatube’s unrivaled position in the daylighting industry,” Westfall shares. “We thank the building industry for embracing our new technologies and the millions of people who allowed us the privilege of installing Solatube in their homes and workplaces.”


Today, Solatube is proud to be expanding its brand through its first-ever home improvement franchise model called Solatube Home. The new Solatube Home franchise will offer the complete Solatube residential product line, including tubular skylights, traditional skylight replacement, solar attic fans, whole house fans and more.

“The first Solatube Home franchise concept will be in sunny Phoenix,” added Westfall. “We believe this will be the perfect market and I’m delighted to return to my hometown to help launch this new franchise with owners Amanda, Justin and Kevin Rhodes.”

The family-owned and operated store will be located at 8055 N. 24th Ave., Suite N, Phoenix 85021 and is scheduled to open at the end of September 2021.
