Tesla Solar Roof tile production begins at Gigafactory 2, customer installs soon to follow
Tesla has begun production of its highly-anticipated Solar Roof tiles from the company’s Gigafactory 2 facility in Buffalo, NY. According to an email sent by Tesla, production of the photovoltaic glass roof tiles began last month and the company expects first customer installations to begin in the following months.
The announcement made by Tesla follows a series of production delays, since CEO Elon Musk first unveiled the company’s glass roof tiles more than a year ago. Tesla initially expected the rollout of the solar shingles to begin in 2017, with the manufacturing of the first two types of tiles — smooth and textured — to start during summer. Due to unforeseen delays, however, the mass production and installation of the shingles was ultimately pushed back, first to late 2017, and later, to 2018.
Over the past few months, several sightings of Solar Roof installations were observed by the Tesla community. These installations, however, turned out to be exclusive only to select employees of the California-based electric car and energy company. The glass solar roof tiles were being manufactured in Tesla’s Fremont factory at the time, a facility that is, while capable, unable to produce tiles on the same pace and scale as Gigafactory 2.
For the most part, Tesla has been fairly silent about the progress of its Solar Roof production. There were signs that a ramp-up was happening, such as solar cell manufacturer Panasonic opening new jobs for product expansion, as well as our report on a Tesla patent featuring an adhesive that can conduct electricity through the solar tiles. With Tesla’s recent announcement, however, the timeline for Solar Roof installations has become significantly clearer.
If any, the fact that the Solar Roofs are now being manufactured in Gigafactory 2 means that the photovoltaic tiles are rolling off the production line faster than ever. This ramp-up seems to be well within Tesla CEO Elon Musk’s expectations. Musk, after all, stated in a 2016 interview that he believes the 1.2 million-square-foot Buffalo, NY facility is capable of potentially producing up to 10 gigawatts of solar products every year.

Bloomberg New Energy Finance analyst Hugh Bromley believes that the Solar Tiles’ appeal will not only be limited to the United States, as other countries such as Australia might prove to be lucrative markets for the Silicon Valley-based energy company.
“It may actually do well in overseas markets where solar-photovoltaic is cheap, and homeowners are used to paying a premium for building materials and cars — such as Australia,” Bromley said in an email, according to a Bloomberg report.

Tesla’s Solar Roof tiles are quite unique in the way that they are both functional and aesthetically pleasing. Developed in collaboration with SolarCity, the Solar Tiles look almost indistinguishable from conventional roof tiles despite featuring a full-fledged solar panel. Being constructed from tempered glass, the tiles are pretty durable too, capable of surviving impacts that would otherwise compromise traditional roof materials like terracotta and slate. Paired with Tesla’s Powerwall 2 unit, the Solar Roof has the potential to give customers true independence from conventional power grids.

Tesla updates Cybertruck owners about key Powershare feature
Tesla is updating Cybertruck owners on its timeline of a massive feature that has yet to ship: Powershare with Powerwall.
Powershare is a bidirectional charging feature exclusive to Cybertruck, which allows the vehicle’s battery to act as a portable power source for homes, appliances, tools, other EVs, and more. It was announced in late 2023 as part of Tesla’s push into vehicle-to-everything energy sharing, and acting as a giant portable charger is the main advantage, as it can provide backup power during outages.
Cybertruck’s Powershare system supports both vehicle-to-load (V2L) and vehicle-to-home (V2H), making it flexible and well-rounded for a variety of applications.
However, even though the feature was promised with Cybertruck, it has yet to be shipped to vehicles. Tesla communicated with owners through email recently regarding Powershare with Powerwall, which essentially has the pickup act as an extended battery.
Powerwall discharge would be prioritized before tapping into the truck’s larger pack.
However, Tesla is still working on getting the feature out to owners, an email said:
“We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026.
This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy.”
Owners have expressed some real disappointment in Tesla’s continuous delays in releasing the feature, as it was expected to be released by late 2024, but now has been pushed back several times to mid-2026, according to the email.
Foundation Series Cybertruck buyers paid extra, expecting the feature to be rolled out with their vehicle upon pickup.
Cybertruck’s Lead Engineer, Wes Morrill, even commented on the holdup:
As a Cybertruck owner who also has Powerwall, I empathize with the disappointed comments.
To their credit, the team has delivered powershare functionality to Cybertruck customers who otherwise have no backup with development of the powershare gateway. As well as those with solar…

He said that “it turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid-forming devices need to negotiate who will form and who will follow, depending on the state of charge of each, and they need to do this without a network and through multiple generations of hardware, and test and validate this process through rigorous certifications to ensure grid safety.”
It’s nice to see the transparency, but it is justified for some Cybertruck owners to feel like they’ve been bait-and-switched.

Tesla starts hiring efforts for Texas Megafactory
Tesla’s Brookshire site is expected to produce 10,000 Megapacks annually, equal to 40 gigawatt hours of energy storage.
Tesla has officially begun hiring for its new $200 million Megafactory in Brookshire, Texas, a manufacturing hub expected to employ 1,500 people by 2028. The facility, which will build Tesla’s grid-scale Megapack batteries, is part of the company’s growing energy storage footprint.
Tesla’s hiring efforts for the Texas Megafactory are hinted at by the job openings currently active on the company’s Careers website.
Tesla’s Texas Megafactory
Tesla’s Brookshire site is expected to produce 10,000 Megapacks annually, equal to 40 gigawatt hours of energy storage, similar to the Lathrop Megafactory in California. Tesla’s Careers website currently lists over 30 job openings for the site, from engineers, welders, and project managers. Each of the openings is listed for Brookshire, Texas.
The company has leased two buildings in Empire West Business Park, with over $194 million in combined property and equipment investment. Tesla’s agreement with Waller County includes a 60% property tax abatement, contingent on meeting employment benchmarks: 375 jobs by 2026, 750 by 2027, and 1,500 by 2028, as noted in a report from the Houston Business Journal. Tesla is required to employ at least 1,500 workers in the facility through the rest of the 10-year abatement period.
Tesla’s clean energy boom
City officials have stated that Tesla’s arrival marks a turning point for the Texas city, as it highlights a shift from logistics to advanced clean energy manufacturing. Ramiro Bautista from Brookshire’s economic development office, highlighted this in a comment to the Journal.
“(Tesla) has great-paying jobs. Not just that, but the advanced manufacturing (and) clean energy is coming to the area,” he said. “So it’s not just your normal logistics manufacturing. This is advanced manufacturing coming to this area, and this brings a different type of job and investment into the local economy.”

Tesla and Samsung SDI in talks over new US battery storage deal: report
The update was related by industry sources and initially reported by South Korean news outlets.
Recent reports have suggested that Tesla and Samsung SDI are in talks over a potential partnership to supply batteries for large-scale energy storage systems (ESS).
The update was related by industry sources and initially reported by South Korean news outlets.
ESS batteries to be built at Samsung’s Indiana plant
As noted in a report from Korea JoongAng Daily, the demand for energy storage systems has been growing rapidly in North America, thanks in no small part to the surge in AI investments across numerous companies. With this in mind, Tesla has reportedly approached Samsung SDI about a potential battery supply deal.
The deal is reportedly worth over 3 trillion Korean won (approximately $2.11 billion) and will span three years, according to The Korea Global Economic Daily. A battery supply deal with Samsung SDI could make sense for Tesla as the company already has a grid-scale battery, the Megapack, which is perfect for industrial use. Samsung SDI could simply supply cells for the EV maker.
Production of the batteries would reportedly take place at Samsung SDI’s joint venture factory with Stellantis in Indiana, which is currently under construction. Samsung SDI recently announced plans to use part of that plant’s EV lines to produce cells for ESS, with a targeted capacity of 30 GWh by the end of next year.
Tesla and Samsung’s partnership
At present, only a handful of manufacturers, including Korea’s LG Energy Solution, Samsung SDI, SK On, and Japan’s Panasonic, are capable of producing energy storage-scale batteries domestically in the United States. A Samsung SDI official issued a comment about the matter, stating, “Nothing has been finalized regarding cooperation with Tesla.”
The possible energy storage system deal adds another layer to Tesla’s growing collaboration with Samsung, which is already in line as a partner in the upcoming production of Tesla’s AI5 and AI6 chips. Early sample manufacturing of the AI6 is expected to begin in South Korea, with mass production slated for Samsung’s Texas-based Taylor foundry when it starts operations.
The AI6 chip will power Tesla’s next wave of high-volume projects, including the Optimus humanoid robot and the autonomous Cybercab service. Musk has called the partnership with Samsung a “real collaboration,” adding that he personally plans to “walk the line” at the Taylor facility to speed up progress.
