In 1954, Bell Labs revealed an invention that might change the way forward for clear energy: The world’s first identified sensible silicon solar cell.
The New York Times reportedly hailed it as “the beginning of a new era, leading eventually to the realization of one of mankind’s most cherished dreams.”
That dream — to make use of the energy of the Sun to create electrical energy — continues to be unrealized, however that doesn’t imply there hasn’t been progress.
All you want to do is take a stroll by way of a metropolis, and you may see them in all places: solar panels powering properties, workplaces, and municipal buildings. Since these panels made their manner onto roofs within the Nineteen Seventies, new knowledge from the Solar Energy Industries Association means that put in residential capability within the U.S. equates to 23 gigawatts in 2021. That accounts for practically 20 % of the U.S.’s complete solar energy generated.
Today, Tesla’s Solar Roof is main the cost with an innovation of its personal: reducing out the center step between constructing the roof and putting in the solar panels. Tesla’s specially-designed tiles imply anybody can outfit their home with what seems like a typical (if a bit shiny) roof that gives the home with power.

The roof tiles are restricted in availability, which implies Tesla Solar Roofs are unlikely to turn out to be as ubiquitous because the bulkier panels we see pasted onto roofs across the neighborhood. Some estimates put the price of Solar Roofs tens of 1000’s of {dollars} above an analogous, extra standard solar panel set up.
Tesla is noticeably tight-lipped about what number of Solar Roofs it has offered. The firm claims it has fitted solar energy methods on 400,000 roofs within the U.S., however doesn’t reveal what number of are Solar Roofs versus retrofit solar panels. Pew Research in 2019 discovered that six % of U.S. householders have put in solar panels, and the Census Bureau discovered there have been 83.5 million owner-occupied housing items on the finish of 2021.
But the few people who do personal a Solar Roof say it has modified their life — identical to the New York Times predicted solar cells may.
“I would definitely recommend the Solar Roof,” Tomas Nochta tells Inverse. Nochta lives in Saddle Brook, New Jersey, works within the hospitality trade, and has a 1,175-square-foot roof with sufficient sunlight-harvesting tiles to generate 7.6 kilowatts of power — sufficient to power Nochta’s home.
“It looks fantastic!”
WHAT IS TESLA SOLAR ROOF?
Elon Musk’s Solar Roof was first unveiled in October 2016. Around two years later, Reuters reported that Tesla had solely activated 12 roofs in California. Installations remained extraordinarily restricted within the U.S. till October 2019, when Tesla unveiled a tweaked model of the roof tiles to allow sooner set up.
Ironically, CEO Elon Musk informed an viewers in 2019 that it might be the “year of the solar roof” — the yr when solar deployments reached their lowest level because the roof’s launch.
In 2020, Musk claimed he needs Tesla’s energy enterprise to develop from lower than 10 % of the corporate to 50 %. Evidence suggests, nevertheless, that Tesla’s solar installs stay comparatively restricted.
Tesla’s solar deployments — which embrace its retrofit solar panels and the Solar Roof — within the fourth quarter of 2021 have been successfully the identical because the fourth quarter of 2020.
Tesla stays the second-largest residential solar installer within the U.S., behind first-placed Sunrun. Tesla’s 2021 complete of 345 megawatts was a formidable 68 % enchancment over the earlier yr, however solar panel provider Sunrun put in 792 megawatts of capability that very same yr. Wood Mackenzie claims Sunrun accounts for 13 % of the full residential solar market.

In April 2021, Tesla introduced plans to lift roof costs primarily based on a given set up’s complexity. Musk admitted the corporate made “significant mistakes” in assessing how laborious it might be to put in sure roofs in an earnings name that month.
Musk’s long-term imaginative and prescient for the long run is one the place it’s “odd” for a roof to not acquire energy to power the constructing inside.
But how does an early adopter really feel about Tesla’s roof? We requested.
Tesla Solar Roof: How all of it got here collectively
In January 2021, Nochta switched on his new roof. His 1,175-square-foot roof has sufficient solar-harvesting tiles to generate 7.6 kilowatts of power. The Tesla Solar Roof makes use of a mixture of solar tiles and dummy tiles; the latter used on the fringe of the set up to allow groups to extra simply minimize edge tiles right down to dimension and match the roof seamlessly to the home.
Nochta first put in solar panels on his home in 2016, equipped by SolarMetropolis. SolarMetropolis merged with Tesla later that yr.
The first set up was lower than three kilowatts — not a lot energy, which meant the couple was utilizing barely greater than they produced. But because the family grew so as to add kids and oldsters, Nochta found it was surprisingly tough to develop the present solar panel system so as to add extra capability. The new panels must work as a part of a twin system, with two inverters feeding into the home.
These inverters are important for getting solar power into the home. As Energy.gov explains, they convert the panels’ direct present electrical energy — with a single voltage in a single path — into the alternating present utilized in properties the place the voltage strikes between constructive and destructive.
“I think the people hate me at Tesla.”
Nochta had “a couple of friends that do roofs” and so they estimated it might value $8,000 to $10,000 to exchange the roof. Including new solar panels would value one other $10,000 to $15,000.
When Inverse checked Tesla’s retrofit solar panel web site, these estimates appeared correct. For a home in Saddle Brook, New Jersey, Tesla costs:
- $10,128 for a 4.8-kilowatt solar panel set up
- $20,256 for a 9.6-kilowatt set up
- $11,000 for one Powerwall battery
A 9.6-kilowatt set up with a battery would come to $31,256 complete. Still, Tesla’s web site notes that prospects may gain advantage from a $6,205 Federal Tax Credit, plus a $7,392 Solar Renewable Energy Credit that would carry the full value right down to as little as $17,659.
That determine was near the quantity Nochta had already guessed he would spend on a brand new roof — so he took the plunge.
“At that point, it’s just, don’t do it, just get a Solar Roof done,” Nochta says.
Nochta’s mission got here to $42,000, together with $14,500 for battery storage. It could have been cheaper for Nochta to get a brand new roof and solar panels — however he’s glad with the ultimate set up and doesn’t remorse the acquisition.
See a video of Nochta’s set up under:
Nochta is considered one of a slowly rising variety of completely happy Solar Roof house owners. Inverse additionally spoke with:
- Amanda Tobler in California, who was an early adopter again in January 2018 together with her 9.85-kilowatt roof
- Jason Lassen in Wisconsin, whose 15.9-kilowatt roof braved the chilly climate in early 2021
- Tony Cho in Florida, whose large 44-kilowatt set up went viral in December 2021
- Richard and Beth Parrish’s California mission in March 2022, which powered two Tesla electrical automobiles
How to get Tesla’s Solar Roof
Nochta ordered his roof in July 2020, months after Musk introduced new third-generation tiles that might allow sooner installations. But Nochta says he additionally did “a lot of research” to try to transfer the mission alongside.
“I was an asshole, I’ll tell you that!” he says. “I think the people hate me at Tesla.”
Nochta organized the permits for constructing the roof himself. He contacted folks to get the right permissions, chased up the utility firm to get approval, and stayed home to make sure each inspection went easily. A earlier contact from the utility firm, who had helped together with his 2016 set up, pitched in once more to help Nochta’s mission.
The folks at Tesla could hate him, however Nochta says a “super nice” worker from Tesla Solar additionally contacted him to see if he may assist them get the mission off the bottom sooner.

The set up course of befell over a few weeks in late 2020. It did not begin nicely: Nochta had deliberate to take away the skylight from his roof. But the installer’s plans retained the characteristic. The mistake would have lowered Nochta’s Solar Roof right down to 7.07 kilowatts.
“I would advise every single person to stay home on the first day and look at the plans of the installer,” he says.
But by November 2020, the roof was absolutely put in. After one other month of ready for closing approval from the utility firm, Nochta switched on the roof in January 2021.

Nochta says his roof has produced 8,148 kilowatt-hours of energy in his first yr of utilization — greater than sufficient to cowl the household’s energy utilization, even with an electrical car.
But he nonetheless has to pay a $5 per thirty days connection charge to maintain his home on the grid, nevertheless — simply in case.
“Our main reasons were to go green and use the Sun to produce our own electricity,” Nochta says. Objective achieved.
Nochta’s actuality is quick changing into different Americans’ desires. In a Pew Research report, 65 % of U.S. adults in 2017 mentioned crucial precedence for addressing the nation’s energy provide needs to be growing alternate options to coal, oil, and gasoline — like wind and solar. This was ranked above increasing manufacturing of present sources like coal and gasoline.
In 2020, that determine had jumped from 65 % to 79 % of Americans who imagine solar and wind — and different inexperienced alternate options — are the precedence.
Musk mentioned in 2019 that the purpose of the Solar Roof was to “make roofs come alive.” With the surging curiosity in renewables, that imaginative and prescient may lastly be simply across the nook.
