New Tesla Solar Roof variants spotted being tested near Fremont Factory
It appears that Tesla is hard at work testing what could very well be the next variants of its flagship residential solar product, the Solar Roof. As could be seen in a recent flyover around Tesla’s Fremont facilities, the company seems to be testing some tiles with a wood-like appearance, as well as some that feature a similar shade to the “slate” tiles that Elon Musk unveiled back in 2016.
A recent flyover of the Fremont Factory from drone operator Gabeincal revealed some notable activities happening in Tesla’s primary EV production site. This time around, the drone operator was able to capture some images of the refresh Model S and Model X at the Fremont Factory test track and one of the Giga Press machines in action. Tesla’s Kato Road facility, which hosts the company’s pilot production line for its 4680 cells, was reportedly full of employee cars as well.
But amidst these activities, one thing that genuinely drew attention was the test houses that Tesla used for its Solar Roof tiles. The video showed three structures that seemed to be undergoing testing, each with a different type of Solar Roof. One appeared to have been fitted with some dark, smooth, or textured tiles; another with what seemed like simulated cedar tiles, and another with tiles that featured a slate-like shade.
The cedar-like tiles in one of the test houses are particularly interesting considering that such a variant was not initially announced by Elon Musk during the Solar Roof’s unveiling back in 2016. During the tiles’ unveiling ceremony, Musk announced four variants that would eventually be available for ordering: a Smooth tile, a Textured tile, a curved Tuscan tile, and some stunning gray Slate tiles. So far, Tesla’s Solar Roof installations have only been comprised of Textured tiles.
Despite this, Tesla’s patents have suggested that the company is pursuing some new Solar Roof variants. One such patent was issued last March, and it described a way for Tesla to obscure, color match, and camouflage its Solar Roof in a way that makes the tiles almost indiscernible from traditional roofing materials. Tesla’s illustrations in the patent hinted at variants of the Solar Roof that are yet to be released, such as the Tuscan and Slate tiles.
It would not be surprising if Tesla is now exploring Solar Roof variants beyond the initial four designs that were announced in late 2016. Cedar Solar Roofs would be a good expansion from the Textured tiles that the company is producing today, after all, as wood shingles have been used in colonial American homes for many years, partly due to their excellent insulation properties and durability. If Tesla does release a Cedar Solar Roof variant, it would not be surprising if it becomes a great seller among homeowners.
Elon Musk has noted that the Solar Roof’s potential would likely be evident this 2021. “I think a future where we’ve got beautiful roofs generating energy that are tough and resilient and better in every way than a natural roof and alive with energy, that’s the future we want. Solar Roof is a killer product. This will become obvious next year,” Musk said in a previous earnings call.

Tesla launches Cybertruck vehicle-to-grid program in Texas
The initiative was announced by the official Tesla Energy account on social media platform X.
Tesla has launched a vehicle-to-grid (V2G) program in Texas, allowing eligible Cybertruck owners to send energy back to the grid during high-demand events and receive compensation on their utility bills.
The initiative, dubbed Powershare Grid Support, was announced by the official Tesla Energy account on social media platform X.
Texas’ Cybertruck V2G program
In its post on X, Tesla Energy confirmed that vehicle-to-grid functionality is “coming soon,” starting with select Texas markets. Under the new Powershare Grid Support program, owners of the Cybertruck equipped with Powershare home backup hardware can opt in through the Tesla app and participate in short-notice grid stress events.
During these events, the Cybertruck automatically discharges excess energy back to the grid, supporting local utilities such as CenterPoint Energy and Oncor. In return, participants receive compensation in the form of bill credits. Tesla noted that the program is currently invitation-only as part of an early adopter rollout.
The launch builds on the Cybertruck’s existing Powershare capability, which allows the vehicle to provide up to 11.5 kW of power for home backup. Tesla added that the program is expected to expand to California next, with eligibility tied to utilities such as PG&E, SCE, and SDG&E.
Powershare Grid Support
To participate in Texas, Cybertruck owners must live in areas served by CenterPoint Energy or Oncor, have Powershare equipment installed, enroll in the Tesla Electric Drive plan, and opt in through the Tesla app. Once enrolled, vehicles would be able to contribute power during high-demand events, helping stabilize the grid.
Tesla noted that events may occur with little notice, so participants are encouraged to keep their Cybertrucks plugged in when at home and to manage their discharge limits based on personal needs. Compensation varies depending on the electricity plan, similar to how Powerwall owners in some regions have earned substantial credits by participating in Virtual Power Plant (VPP) programs.
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…
— Wes (@wmorrill3) December 12, 2025
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.”
