These new nailable solar shingles can be installed like a traditional roof [Update]


The world’s “first” nailable solar shingle, the Timberline solar-powered shingle, was launched on January 3 by GAF Energy, the sister company of GAF, the largest roofing and waterproofing company in North America.

January 6: Electrek spoke with a representative from GAF Energy about the cost, efficiency and specifications of their Timberline solar power shingle, and that’s what they said.

On cost:

Timberline Solar is competitive with rack mounted systems and is more affordable than other solar roofs. That’s about half the cost of the Tesla solar roof.

The most affordable time to switch to solar power is when you’re in the market for a new roof, turning two home improvement projects into one. Plus, solar power helps pay for the roof by lowering your monthly utility bill.

GAF Energy chairman Martin DeBono said replacing a $ 15,000 roof (not including solar power) would likely cost $ 30,000 (before subsidies) with Timberline solar power.

GAF Energy’s roofing partners set the prices directly for the consumer and it depends a lot on the roof, shading and a number of other factors.

On efficiency:

The emitter and rear mono passivated cells (PERC) we use are, on average, 22.6% efficient. This will be the most reliable number if you are looking for a number, as our shingle technology is ahead of standardized efficiency tests (intended for large rigid panels).

Based on our internal testing, GAF Energy’s custom diode layout allows the system to outperform rack-mounted systems in real-world conditions without additional bulky electronics and associated additional labor. Finally, the flexible form factor of the shingles allows GAF Energy to install more solar power in areas where a traditional 5ft by 3ft panel is simply not suitable, providing more options for customers who could not. not use solar energy before.

The weight of the Energy shingle is 10.1 pounds (4.58 kg) and its dimensions are 64 1/4 ″ x 17 1/8 ″ x 1 ″ (1632 x 435 x 26 mm). The permitted roof slope is 2:12 or greater, and the maximum installation altitude is 13,123 feet (4,000 m). The average ambient temperature range is -40F to 122F (-40C to 50C).

The wind classification is ASTM D3161 Class F – that is, shingles that have passed wind tests at 110 mph.

Regarding impact resistance, shingles are classified from class 1 to 4, with class 4 shingles having the highest resistance. The energy shingle is UL 2218 class 1 classified.


January 3: The Energy shingle is combined with other standard roofing components to create the “Timberline Solar” roofing system. GAF Energy claims to have the only product to integrate solar technology into existing roofing materials and processes, resulting in a full-fledged solar roof.

GAF Energy claims that its Energy shingles have weather resistance performance comparable to that of roofing shingles from GAF, the Timberline HD / HDZ.

All nailable solar shingle components are coplanar and the electronic components are located on the front of the shingle rather than the back so they are easily accessible for maintenance.

In September 2021, Timberline Solar achieved UL 7103 certification, which allows GAF Energy to install the system on residential rooftops as a roofing product and solar power product, the first of its kind to be recognized as both.

GAF Energy also worked with the Albuquerque-based company Sandia National Laboratories, a research and development laboratory of the United States Department of Energy, to verify the strength, durability and overall readiness of the product.

One of Sandia’s missions is to drive technical innovation in the solar sector as part of a larger DOE effort to reduce costs, increase efficiency and continue the deployment of solar technologies.

More than five million new roofs are installed on American homes each year – one in four of those roofs comes from GAF. With access to GAF’s national network of contractors, GAF Energy is well positioned to develop residential solar on the mass market.

Martin DeBono, President of GAF Energy, said:

At GAF Energy, we have the ability to evolve this technology like no one else thanks to GAF, delivering an integrated weatherproof solar product that is affordable and designed for homeowners across the country.

Energy shingles will be manufactured on the company’s premises new facility in San Jose, Calif., and launched this month.

GAF Energy did not give us the specifications or prices for these new tiles, so we don’t know how efficient they are in terms of power generation, or how expensive they are. But if we assume they’re efficient and aren’t outrageously expensive, that could be a game-changer.

It makes sense to combine roofing and solar installation, as GAF Energy does. If the process is streamlined, more homeowners will adopt rooftop solar power.

I will find out and report… and if the answers to the two questions above are correct, I would like them on my own roof. [See above for update.]
