Tesla’s solar roof cost calculator validated by Consumer Reports
Consumer Reports has double-checked Tesla’s math behind its solar roof tile calculator and confirmed that estimates provided by the company are accurate. The consumer ratings agency notes that pricing varies depending on where the individual lives, as geography dictates available sunshine and utility rates which ultimately determines if the innovative solar roof tiles makes sense as a purchase.
Tesla’s new solar roof tiles are warrantied for 30 years against weather and ensures that the new roof doesn’t leak after installation. The roof tiles themselves are physically warrantied forever or as long as the home lasts, “whichever comes first” per Tesla.
It’s important to note that conventional solar panels will almost always come in at a lower total installed cost, a faster “breakeven point” and ultimately generate more value for the homeowner over their useful life than a home with a Tesla Solar Roof. On the other hand, the new roof tiles do come with a very impressive warranty that adds value beyond just their solar energy production value.
Consumer Reports starts off with a huge admission that it did not factor in any solar incentives or rebates in their calculations. In the US, this is a 30% rebate at the federal level alone and represents an inexcusable omission in their calculations. With Tesla’s numbers coming in below the target price of $24.50 per square foot without the rebates, it is clear that the new solar roof tiles met the financial requirements of Consumer Reports.
To see what the payouts look like in a few areas in the U.S., Consumer Reports pulled the numbers from Tesla’s website to see if the new solar roof tiles would be a good investment in three very different area: New York, Texas and California.
The value of Tesla’s Solar Roof ultimately hinges on the amount of energy the solar roof tiles will generate. Sunny California tops the list as the state that will provide the most return for a solar roof investment, while Texas rounds out a close second. New Yorkers looking to purchase a solar roof will see the least value purely because of its northern location which receives less face time with the sun. This dictates the volume of energy the tiles can create, and thus how much money it can save a homeowner.
The other contributing factor to the equation is the price of electricity in the area. If the price of electricity is high, the value of the energy produced by the tiles is effectively worth more. In New York state, the average price of electricity is above the national average of 12 cents per kilowatt hour, coming in at 17.5 cents per kilowatt hour. Texas is at the opposite end of the spectrum at 11.41 cents per kilowatt hour and represents a less lucrative home for a solar system while California takes first place with the highest price at 18.68 cents per kilowatt hour (per EIA data from Feb 2017).
After running the numbers through Tesla’s Solar Roof calculator which you can do for yourself, Consumer Reports found that the installation in New York would payout and save the homeowner money over 30 years, largely due to the high price of electricity in the area. Consumer Reports also noted an additional state incentive to install solar in New York that would potentially slash another $5,000 off of the total purchase price.
Installing the solar roof tiles on a home in Texas would not payout due to the lower cost of electricity in the area. Finally, the home in California was a shoe in with high electricity cost and abundant sunshine.
The Consumer Reports analysis highlights that Tesla’s Solar Roof already makes sense in many areas of the nation. Even if the tiles don’t make sense on your home, it is worth checking to see if a traditional solar panel system could save you money as they are much easier to install and generally have better payouts. You can easily check to see if solar makes sense in your area by getting a solar cost estimate.

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.
