Tesla Solar Roof 12kW installation completed in one day
Weddle and Sons Roofing recently managed to complete a 12kW Tesla Solar Roof installation in a single day. The same roofing company installed a 15kW Tesla Solar Roof system in just four days late last year.
Based on its recent installation, Weddle and Sons Roofing has shown tremendous improvement in three months. The roofing company stated that the installers started and ended the project with headlamps, hinting that the team woke up early and finished the project late to hit the one-day mark.
Weddle and Sons is one of the first roofing companies to announce a one-day installation for Tesla’s solar shingles. During Tesla’s third-quarter earnings call, the EV manufacturer’s Global Head of Commercial Energy RJ Johnson talked about one-day Solar Roof installations.
“Solar Roof is especially exciting as we’ve gained significant experience over the last year in the installation process, which is a key enabler to scale the business. We’ve recently demonstrated our ability to complete Solar Roof installation in just one day,” Johnson said.
He noted that the one-day timeline did not include the removal of a house’s existing roof and preparation for the Solar Roof installation. Johnson added that weather, complexity, the size of the installation, and other factors could also increase the timeline.
In the case of Weddle and Sons’ one-day installation, the tear-off of the existing roof took place a week before the installation because local jurisdiction required a mid-roof inspection, and they did some decking repairs.
Weddle and Sons Roofing is just one of the many professional third-party installers Tesla is working with on Solar Roof installations. The timeline for Solar Roof installations may depend on the company homeowners choose to work with on the project. Weddle and Sons appears determined to meet Tesla’s timeline for Solar Roof installations, and other roofing companies working with Tesla may show the same determination as well.

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.
Tesla announces 100k Powerwalls are participating in Virtual Power Plants
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.
