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 VP hints at Solar Roof comeback with Giga New York push
The comments hint at possible renewed life for the Solar Roof program, which has seen years of slow growth since its 2016 unveiling.
Tesla’s long-awaited and way underrated Solar Roof may finally be getting its moment. During the company’s Q3 2025 earnings call, Vice President of Energy Engineering Michael Snyder revealed that production of a new residential solar panel has started at Tesla’s Buffalo, New York facility, with shipments to customers beginning in the first quarter of 2026.
The comments hint at possible renewed life for the Solar Roof program, which has seen years of slow growth since its 2016 unveiling.
Tesla Energy’s strong demand
Responding to an investor question about Tesla’s energy backlog, Snyder said demand for Megapack and Powerwall continues to be “really strong” into next year. He also noted positive customer feedback for the company’s new Megablock product, which is expected to start shipping from Houston in 2026.
“We’re seeing remarkable growth in the demand for AI and data center applications as hyperscalers and utilities have seen the versatility of the Megapack product. It increases reliability and relieves grid constraints,” he said.
Snyder also highlighted a “surge in residential solar demand in the US,” attributing the spike to recent policy changes that incentivize home installations. Tesla expects this trend to continue into 2026, helped by the rollout of a new solar lease product that makes adoption more affordable for homeowners.
Possible Solar Roof revival?
Perhaps the most intriguing part of Snyder’s remarks, however, was Tesla’s move to begin production of its “residential solar panel” in Buffalo, New York. He described the new panels as having “industry-leading aesthetics” and shape performance, language Tesla has used to market its Solar Roof tiles in the past.
“We also began production of our Tesla residential solar panel in our Buffalo factory, and we will be shipping that to customers starting Q1. The panel has industry-leading aesthetics and shape performance and demonstrates our continued commitment to US manufacturing,” Snyder said during the Q3 2025 earnings call.
Snyder did not explicitly name the product, though his reference to aesthetics has fueled speculation that Tesla may finally be preparing a large-scale and serious rollout of its Solar Roof line.
Originally unveiled in 2016, the Solar Roof was intended to transform rooftops into clean energy generators without compromising on design. However, despite early enthusiasm, production and installation volumes have remained limited for years. In 2023, a report from Wood Mackenzie claimed that there were only 3,000 operational Solar Roof installations across the United States at the time, far below forecasts. In response, the official Tesla Energy account on X stated that the report was “incorrect by a large margin.”

Tesla China’s Megafactory helps boost Shanghai’s battery exports by 20%: report
Located in the Lingang New Area of the Shanghai Free Trade Zone, the Tesla Megafactory has been running at full throttle since opening in February.
Reports from China have indicated that the Tesla Shanghai Megafactory has become a notable player in China’s booming battery export market.
Located in the Lingang New Area of the Shanghai Free Trade Zone, the Tesla Megafactory has been running at full throttle since opening in February. It produces Tesla Megapack batteries for domestic and international use.
Tesla Shanghai Megafactory
As noted in a report from Sina Finance, the Tesla Shanghai Megafactory’s output of Megapack batteries helped drive a notable rise in lithium battery shipments from the city in the first three quarters of 2025. This is quite impressive as the Megafactory is a rather young facility, though it has been steadily increasing its production capacity.
“The establishment of this benchmark factory has not only driven the rapid development of Shanghai’s energy storage industry but also become a new growth engine for foreign trade exports. Driven by the Tesla energy storage factory’s opening, Shanghai’s lithium battery exports reached 32.15 billion yuan ($4.5 billion) in the first three quarters, a 20.7% increase,” the publication wrote.
Ultimately, the Shanghai Megafactory has proved helpful to the city’s “new three” industries, which are comprised of new energy vehicles, lithium batteries, and photovoltaic systems. Exports of the “new three” products reached 112.17 billion yuan ($15.7 billion), a 6.3% year-over-year increase during the same period. The city’s total trade volume grew 5.4% year-over-year as well, with exports up 11.3%, driven largely by the clean energy sector’s performance.
Energy storage is helping Shanghai
Since opening in February, the Shanghai Megafactory has been firing on all cylinders. In late July, Tesla Energy announced that the new battery factory has successfully produced its 1,000th Megapack unit. That’s quite impressive for a facility that, at the time, had only been operational for less than six months.
Speed has always been a trademark of the Shanghai Megafactory. Similar to Tesla’s other key facilities in China, the Megafactory was constructed quickly. The facility started its construction on May 23, 2024. Less than a year later, the site officially started producing Megapack batteries. By late March 2025, Tesla China noted that it had shipped the first batch of Megapack batteries from the Shanghai plant to foreign markets.

Tesla recalls Powerwall 2 units in Australia
Tesla will recall Powerwall 2 units in Australia after a handful of property owners reported fires that caused “minor property damage.” The fires were attributed to cells used by Tesla in the Powerwall 2.
Tesla Powerwall is a battery storage unit that retains energy from solar panels and is used by homeowners and businesses to maintain power in the event of an outage. It also helps alleviate the need to rely on the grid, which can help stabilize power locally.
Powerwall owners can also enroll in the Virtual Power Plant (VPP) program, which allows them to sell energy back to the grid, helping to reduce energy bills. Tesla revealed last year that over 100,000 Powerwalls were participating in the program.

The Australia Competition and Consumer Commission said in a filing that it received several reports from owners of fires that led to minor damage. The Australian government agency did not disclose the number of units impacted by the recall.
The issue is related to the cells, which Tesla sources from a third-party company.
Anyone whose Powerwall 2 unit is impacted by the recall will be notified through the Tesla app, the company said.
