Tesla Solar Roof certified with top UL safety rating, Fremont begins pilot production
Tesla has moved one step closer to getting its new Solar Roof tile product onto the rafters of homes after receiving the highest safety rating by U.S. safety certification company Underwriters Laboratory (UL).
Tesla’s Solar Roof Class A certification granted by the UL gives the energy-producing glass roof tiles the highest fire resistance rating possible, largely because of the high-strength glass material used by Tesla which proves to be extremely fire resistant and nearly indestructible. The UL Roof Rating summarizes the classification as:
“Class A roof coverings, which are effective against severe fire test exposures”
UL rated roofing products are required by many local ordinances, with the higher ratings required in fire prone areas like much of Southern California. “There are several requirements for roof covering fire classifications in model codes and city and county ordinances. These requirements are dependent on the type of building construction and the location of the building. Some jurisdictions, due to the history of fire incidents or because of their location, have increased the minimum fire classification requirements in the IBC.” reads the UL Roof Ratings classification sheet.
Tesla-acquired SolarCity has posted dozens of new jobs for skilled roofers, primarily in California, that must have “roofing experience; including metal, concrete tile, clay tile, comp, shingle, or wood shake”. Compared to traditional roofing, installing a rooftop comprised of thousands of individual solar tiles that must be installed with perfection and wired together puts a completely new spin on traditional roofing.

If the roof is not installed correctly and leaks, or has technical issues with the solar generation, warranty costs would mount quickly. The Tesla Solar Roof product have an infinity warranty on the individual tiles and carry a 30-year warranty against leaks and for the solar production.
Tesla’s Solar Roof cost calculator factors in a Powerwall 2.0 unit into the quote, by default, and as such most customers will end up with one or more on the wall of their garage. In California, where solar net metering agreements are very pro-consumer, the payback on a Powerwall is essentially non-existent. Powerwall does enable homeowners to keep the power generated by the solar system in the house which can be used at night when the panels are not generating any power. With the strong branding of Tesla products and the lack of education of most solar customers, it is likely that the Powerwall upsell will be effective.
Tesla is currently undergoing pilot production of the Textured and Smooth Glass roof tile product from the company’s Fremont, California factory. Once volume production begins this summer from Gigafactory 2 near Buffalo, New York, Tesla’s R&D team in Fremont will parallel path development of the Tuscan and Slate finishes which are aimed at early 2018 production.
Consumer Reports’ recent cost analysis of Tesla’s Solar Roof indicated that the investment makes sense in many areas of the nation. Those looking to take a more traditional and affordable route with solar should consider flat panel solar systems as it’s much easier to install and will have better short term payouts.

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’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.”
