Tesla Solar Roof is becoming a legitimate bargain against high-end roofs + solar
Tesla took a while before it was able to start a serious ramp of its Solar Roof tiles, but it appears that the wait will be worth it. As the electric car maker continues to expand its Solar Roof installations in the United States, it is starting to become evident that the aesthetically-pleasing solar shingles are a bargain in its class. At its current prices, Tesla’s Solar Roof presents savings compared to high-end roof options plus a traditional solar system.
The Tesla Solar Roof is actually one of the least expensive in its class of building-integrated PV options. While it’s true that the Solar Roof’s competitors are fewer than, say, the Model 3’s rivals in the EV segment, the flagship shingles do have some competition. These include DeSol’s Power Tiles, as well as the Luma Solar Tiles, both of whom adopt the same concept as the Tesla Solar Roof. The Solar Roof undercuts both competitors in price.
The Tesla Solar Roof is estimated to cost about $2.11 per installed watt, as noted by Green Building Advisor. This is far more affordable than the price of the DeSol Power Tiles, which stand at about $7 per installed watt. Even the Luma Solar Tiles, which are closer in appearance to Tesla’s Solar Roof V3, command a price of about $4.50 per installed watt. But this is not all, as the Solar Roof could be a reasonable alternative to a setup that involves traditional roofing materials and conventional solar panels as well.
A rough comparison outlined in a previous webinar from Solar Oregon estimates that replacing an entire 2,000 square-foot roof with Tesla Solar Roof tiles will cost about $42,500. This is more expensive than installing a regular asphalt-shingle roof with a traditional racked solar system, but it is more affordable when compared to more premium materials like metal, slate, and tiles combined with a conventional solar array.
This was highlighted earlier this year by Tesla owner-enthusiast Ben Sullins, who estimated that a 9.2 kW Solar Roof system will cost about $56,000. And while a standard shingle roof with a 9.2 kW PV system will likely cost just around $42,000, premium roofing materials with solar panels are far more expensive. Sullins estimated that a metal roof with a comparable PV system will cost about $70,000, a tile woof with a 9.2 kW solar system will cost about $111,000, and a slate roof with traditional panels will set back homeowners around $134,000.
With this in mind, and with Tesla’s tendency to keep innovating, there is a good chance that the Solar Roof will get even more affordable in the near future. At an estimated $2.11 per installed watt, after all, the Solar Roof is already a disruptor in its segment, and it is already taking steps to get closer to the costs of conventional roofing materials plus solar panels. Granted, this disruption is yet to become evident as the Solar Roof is only available in some zip codes of 16 US states today, but the following year will likely be exciting for the flagship solar product.
This was highlighted by Elon Musk during Tesla’s Q3 2020 earnings call. When asked about that ramp of the flagship product, Musk noted that the potential of the Solar Roof will be evident in 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 regular 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.

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.
