First of all, the idea of solar shingles had been around and used small applications.
Therefore, they really first burst onto the commercial market in 2011. Then it was
estimated that they would sell for far less than standard solar panels. Profits 
were estimated to exceed $10 billion within a decade, and many people believed that
the future of solar had arrived.

While those initial projections were proven incorrect, solar shingles stand ready
to finally make a larger splash on the market. This is also thanks to new innovations
that will be hitting the market in 2018. Once more, a turning point in the solar
world has been predicted. One with experts surmising that thanks to advancements
like Tesla’s Solar Roof, [the entire clean energy market could change forever](https://futurism.com/solar-expert-predicts-tesla-will-be-a-game-changer-for-clean-energy).

But to even attempt to predict the future of solar shingles, you first have to understand
its history. I mean, where did it come from? Also, where did it go wrong? Finally,
where has it gone right?

##### **Birth of the Concept**

While Dow announced the first major solar shingle to hit the market in 2009, solar
shingles were a dream that took decades to realize. The initial patent for the technology
that would give birth to solar shingles was[filed on August 24, 1976](https://patents.google.com/patent/US4040867).

Therefore, the filing reads, “The invention relates to solar cell arrays. Ones also
particularly those which are designed for use on roofs or buildings. It has been
heretofore suggested that solar cell arrays be arranged with solar cell wafers in
stepped arrangement over a rooftop or the like. It has also been suggested to cover
a helmet or the like with a solar cell array for the collection of radiant energy.
Further suggestions involve building blocks or the like in which solar cells are
encapsulated.”

As well, [solar shingles](https://greenlivingguy.com/2025/07/solar-ev-homeowners-incentives-before-they-expire/)
were developed to combat one of the most common objections homeowners have when 
it comes to solar panels.

[Many people find them to be ugly](https://www.theepochtimes.com/are-solar-panels-ugly-or-beautiful_2131189.html).
Look, I meqn solar shingles were designed to lay flush against standard asphalt 
roof tiles in order to blend in with them so, to the naked eye, the solar cells 
would be invisible.

##### **Failure of the Powerhouse**

Dow Chemical announced the first major residential solar shingle in 2009, the Dow
Powerhouse. At the time of announcement, Dow touted the powerhouse as the future
of the solar industry, estimating profits of [$5 billion by 2015 and $10 billion by 2020](https://www.reuters.com/article/us-dow-solar/dow-sees-huge-market-in-solar-shingles-idUSTRE5944NP20091006).
They also believed, at the time, that solar shingles would sell at 10-15% less per
Watt than traditional solar panels.

In addition, the announcement was also met with much enthusiasm. Especially by the
scientific community. TIME Magazine even declared the Dow Powerhouse one of the[50 Best Inventions of 2009](http://content.time.com/time/specials/packages/article/0,28804,1934027_1934003_1933958,00.html),
based solely on a prototype.

When the product hit the market in 2011, it stumbled due to higher costs than anticipated,
coupled with a lack of efficiency when compared to traditional panels. The solar
[shingles](https://greenlivingguy.com/2020/03/tesla-needs-tech-hiring-in-buffalo/)
were selling from $4-$12 per Watt, while tried and true solar panels were only $
3.50 (more on solar costs at PowerScout.com)

These issues proved to be insurmountable as, five years later, with only 1,000 homes
having installed the product in 18 states! So then [Dow discontinued the Powerhouse line](https://www.treehugger.com/solar-technology/dow-pulls-plug-its-powerhouse-solar-shingles.html).
This announcement coincided with the company’s merger with DuPont. All which saw
[25,000 jobs eliminated](https://www.greentechmedia.com/articles/read/dow-chemical-sheds-solar-shingle-business#gs.YgG=JE8)
worldwide.

Around that same time, a new player arrived on the solar shingle scene in the form
of Tesla.

##### **The Tesla Solar Roof**

When tech powerhouse Tesla[purchased the national solar manufacturer, SolarCity](https://www.usatoday.com/story/tech/news/2016/11/17/tesla-solarcity-deal-xxxx/94020994/)
for $2 billion in late 2016. So it was clear that CEO Elon Musk had a vision for
the solar industry. That came to light in 2017. All with the announcement and rollout
of the [Tesla Solar Roof](https://www.tesla.com/solarroof), and a series of advanced
solar shingles. All which were designed to mimic the appearance of various styles
of roof tiles.

Currently, the Gigafactory 2 in Buffalo, New York is going to Solar shingles in 
Partnership with [Panasonic USA](https://greenlivingguy.com/2013/01/ja-solar-modules-pass-pid-tests-conducted-by-tuv-sud/).
Lastly, Elon went up there to talk through production concerns.

Furthermore, the Solar Roof is also available in smooth and also in textured glass.
In addition to French slate, and Tuscan designs. At this time, only the glass variations
have been released in the United States. The Solar Roof stands to not only blend
in seamlessly while providing utility savings. Tesla also touted its ability to 
[withstand heavy weather conditions. ](https://www.tesla.com/solarroof)So I mean
in a way that far exceeds traditional roof tiles.

However, the [Tesla Solar Roof in partnership with Panasonic](https://greenlivingguy.com/green-living-consulting-services/sponsors/)
Solar is not without its downsides. This new product also comes at a high cost. 
Some estimate that the Solar Roof is 70% more expensive than installing a traditional
solar system on a sturdy roof. Also and that it only generates [70% of the power](https://solaractionalliance.org/tesla-solar-roof-vs-traditional-solar-panels/)
that standard solar panels do.

##### **Return of the Powerhouse**

With Tesla set to dominate the solar shingle landscape in 2018 following the full
rollout of the Solar Roof, Dow is stepping back into the game and attempting to 
revive the Powerhouse brand.

In addition, the Powerhouse 3.0 was developed through a partnership. All seeing 
[Dow team up with RGS Energy](https://www.streetinsider.com/Corporate+News/RGS+Energy+%28RGSE%29+Announces+Pact+with+Dow+Chemical+to+Commercialize+POWERHOUSE+Solar+Shingle/13359446.html).
This new version of [Dow’s original product](https://greenlivingguy.com/2014/01/dow-building-insulation-products-achieve-recertificatio/)
will be made using standard silicon solar cells. So therefore and rather than the
more expensive CIGS technology of its predecessors. This shift in material will,
according to Dow and RGS. Finally and all the while, it will [improve efficiency while controlling costs](https://www.streetinsider.com/Corporate+News/RGS+Energy+%28RGSE%29+Announces+Pact+with+Dow+Chemical+to+Commercialize+POWERHOUSE+Solar+Shingle/13359446.html).

##### **The Future of Solar Shingles**

In conclusion, the stage appears to be set for a battle in solar shingle supremacy.
All between a resurgent Dow and Tesla. While Tesla’s name value and positive reputation
will be difficult to overcome. Yet Dow appears to be armed with a plan forged in
the fires of their previous errors. It will be interesting to see what the landscape
of the industry looks like. Especially through 2020 and into 2021.
