World’s first nailable solar shingle gets an upgrade, now produces 23% more power

• GAF Energy recently released the Timberline Solar ES 2, an upgraded model of the world’s first nailable solar shingle, which the company originally launched in 2022. This new solar technology generates 23% more power than its predecessor.
• The shingles can withstand wind speeds up to 130 miles per hour, and each unit is capable of generating 57 watts of solar power.
• The company wants to scale up production of this technology and opened a 450,000-square-foot manufacturing facility in Georgetown, Texas, late last year to help achieve that goal.

An upgraded version of the world’s first nailable solar shingle was introduced in February 2025. GAF Energy’s recently released Timberline Solar ES 2 can reportedly generate 23% more power than its predecessor, which the New Jersey-based company first launched in 2022.

“Timberline Solar ES 2 represents everything we’ve learned about solar roofing, enhanced by extensive feedback from contractors and homeowners,” said Martin DeBono, president of GAF Energy. “It’s an innovation that delivers a solar shingle that is more powerful, even easier to install, and more versatile than ever before.”

What can these solar shingles do?

This technology serves as both a roofing material and a source of solar energy. According to the company, the new model offers improved installation efficiency and greater design compatibility. These shingles are designed to direct water away from a home’s foundation, and are able to withstand wind speeds of up to 130 miles per hour.

With a power output of 57 watts per unit, each individual shingle can generate enough electricity to power small household devices, such as a medium-sized TV or a desktop computer. Additionally, at less than a quarter inch thick, the shingles are thinner than traditional solar panels, which typically range from 1.5 to 2 inches in thickness.

What happens next?

GAF Energy has expressed plans to scale up production of these solar shingles. The company recently completed a 450,000-square-foot manufacturing facility in Georgetown, Texas, as part of its efforts to expand its solar roofing solutions.
