How much will a Tesla Solar Roof cost on my home?
Updated May 10, 2017: Tesla has provided an online calculator that attempts to compute the cost of a Tesla Solar Roof based on a home’s approximated square foot and number of stories. Single story homes are presumed to have double the roof surface area than a 2-story home with the same interior space. Here are some estimates on how much a Tesla Solar Roof will cost depending on the size of the home:
- 1.500 square feet (1 story) – $55,600
- 1,500 square feet (2 story) – $29,500
- 2.000 square feet (1 story) – $72,700
- 2,000 square feet (2 story) – $38,300
- 3,000 square feet (1 story) – $55,600
- 3,000 square feet (2 story) – $106,600
- 5,000 square feet (1 story) – $155,300
- 5,000 square feet (2 story) – $89,700
Solar Roof costs outlined are based on 60% solar coverage and does not take into account value of energy produced from the roof tiles themselves. The cost also does not factor in any local solar tax credits which varies by region.

Tesla’s new Solar Roof tiles are the hot topic of conversation right now. At the official reveal event, Elon Musk asked rhetorically, “So, why would you buy anything else?” In a new analysis, Consumer Reports (CR) tries to answer that question.
In the absence of pricing information from Tesla, Consumer Reports decided to make some assumptions of its own. People may quibble with them, but they at least establish a baseline that can be used to begin the discussion.
CR reached out to some knowledgeable roofing sources such as the Slate Roofing Contractors Association, the Tile Roofing Institute, and the folks behind the Remodeling 2016 Cost vs. Value Report. Assuming a typical roof size in the US of 3,000 square feet, it determined the average cost of a clay tile roof is $16,000, an asphalt shingle roof is $20,000 and a slate roof is $45,000.
CR then assumed the average annual utility bill for that typical home is $2,000. Multiplying that by the 30 year life span Tesla says customers can expect from their Solar Roof, that comes out to $60,000. Consumer Reports then backed out the $6,500 assumed cost of installing a Tesla Powerwall 2 from the projected cost of electricity and declared that a Tesla glass tile roof would have to cost no more than $73,500 in order to compete successfully with a normal asphalt shingle roof.
Note that in these calculations, the customer is expected to pay for 30 years of electricity up front. CR makes no adjustment for what the costs of financing that amount immediately might amount to over that same 30 year period. The analysis also does not factor in the location of the home, the angle of the roof, or its orientation toward the sun. Clearly, a roof in southern California will generate more electricity over its useful life than a roof in the northeast.
The team at CR also assume the combination of a solar roof and a Powerwall system will supply all of a home’s energy needs without the need to draw (and pay for) additional power from the grid. Finally, no allowance is made for the monthly fees many utility companies assess to homeowners who have residential solar systems. The industry position is that rooftop solar places an undue burden on the utility grid and forces the bills of other customers to increase.
Elon said last Friday the Tesla Solar Roof tiles will “look better than a normal roof, generate electricity, last longer, have better insulation, and actually have an installed cost that is less than a normal roof plus the cost of electricity.”
He is absolutely right about the aesthetics.” People like the idea of being energy efficient, but solar panels can be an eyesore,” says Giovanni Bozzolo, a partner at Roof4Less roofing in Seattle, Wash. “To be able to combine the energy savings with aesthetics would be a very big thing in the industry. But the pricing has to be right.”
So, will the pricing be right? After Consumer Reports checked all its sources, made all its assumptions, and crunched all its numbers, it said in order to be competitive, a Tuscan tile roof needs to cost less than $69,500 ($2,300 per 100 square foot). A smooth or textured tile roof needs to cost less than $73,500 ($2,450 per 100 square feet). A slate tile roof needs to cost less than $98,500 ($3,300 per 100 square feet).
Two important factors we don’t know are the cost of installation for a Solar Roof or the skill level installers will need. “Roofers aren’t electricians and vice versa, so I’m most interested in seeing how the costs of labor affect the end price to consumers,” says Vikram Aggarwal, CEO of EnergySage, an online marketplace of solar installers.
Elon Musk is right about one thing. The Solar Roof products we saw at Universal Studios last week are drop dead gorgeous. Any home owner would love to have one. The question is, will they be a luxury item, like a Tesla Model S, or affordable to a broad range of homeowners, like a Model 3? The answer is, no one knows. Asked for comment, a Tesla spokesperson told Consumer Reports, “We haven’t released details on pricing.”
Tesla just trademarked ‘MEGAPOD’ with the United States Patent and Trademark Office (USPTO), its latest move in what seems to be a hint that the company is incredibly focused on its AI efforts and storage needs as compute increases.
The application carries serial number 99893717 and lists the applicant as Tesla, Inc., located at 1 Tesla Road, Austin, Texas 78725.
The filing remains in ‘live pending’ status, and it is a new application waiting for assignment to an examining attorney. It has not yet been published or registered.

According to the official goods and services description in the application, Tesla describes ‘MEGAPOD’ as:
“Modular data center hardware systems for artificial intelligence computing, comprised of computer servers, computer hardware for artificial intelligence processing, computer networking hardware, electrical power distribution units, and cooling systems, sold as a unit; self-contained modular computing hardware systems for artificial intelligence workloads; integrated computer hardware platforms for artificial intelligence computing, namely, enclosures containing computer hardware, power distribution hardware, and cooling hardware, sold as a unit; downloadable software for monitoring, managing, optimizing, and regulating modular artificial intelligence computing hardware systems.”
This description specifies complete, self-contained modular units that integrate servers and specialized AI processing hardware with networking components, power distribution, and cooling systems. It also includes associated downloadable software for oversight and optimization of these systems. The language emphasizes hardware sold “as a unit” and enclosures that combine the necessary elements for AI computing workloads.
Tesla has an established history of developing and commercializing modular hardware systems. Its Megapack product line, for example, consists of utility-scale battery energy storage systems designed as containerized units for grid applications. The MEGAPOD filing follows a similar pattern of protecting a name for modular, integrated hardware platforms, this time focused on artificial intelligence computing infrastructure.
This could be an early move, especially as Tesla did not have trademark rights to the word ‘Cybercab,’ the name of its self-driving, ride-hailing-focused vehicle.
Trademark applications of this type allow companies to secure priority rights to a name for defined categories of goods and services. The USPTO examines applications for compliance with legal requirements, including distinctiveness and absence of conflicts with prior marks. If the application proceeds successfully through examination, publication, and any opposition period, it could result in a federal trademark registration providing nationwide protection. This is what Tesla’s obvious intention is with ‘MEGAPOD.’
Public reports and analysis suggest MEGAPOD could represent modular, container-style AI computing pods designed for easy deployment. These would bundle servers, AI accelerators, power systems, and cooling into self-contained units suitable for distributed AI workloads. This approach aligns with Tesla’s announced AI compute strategy.
In March 2026, Elon Musk outlined plans for “Digital Optimus” (also referred to as Macrohard), a joint Tesla-xAI project for AI agents capable of handling complex digital tasks. The plans include running these agents on Tesla’s AI4 hardware in parked vehicles as well as dedicated compute units installed at Supercharger stations, which collectively offer substantial unused electrical capacity.
What is Digital Optimus? The new Tesla and xAI project explained
A modular hardware platform like the one described in the ‘MEGAPOD’ filing would support scalable, rapid deployment of such distributed compute resources. It could complement Tesla’s other AI infrastructure efforts, including the Dojo supercomputer used for training models and the development of AI systems for autonomous driving and robotics, by enabling edge or regional AI inference without reliance on traditional centralized data centers.
In a notable intersection of Big Tech powerhouses, Meta, led by Mark Zuckerberg, has partnered with Canadian energy infrastructure giant Enbridge on a significant renewable energy initiative that will rely on battery technology from Elon Musk’s Tesla.
The project, which was announced this week, marks another step in Meta’s aggressive push to power its expanding data center operations with clean energy, dispelling many of the complaints people have about them.
This new development is located near Cheyenne, Wyoming, and will feature a 365-megawatt (MW) solar farm paired with a 200 MW/1,600 megawatt-hour (MWh) battery energy storage system, also known as BESS. Tesla is providing the batteries for the project, valued at roughly $200 million.
The story was originally reported by Utility Dive.
This Wyoming project represents the first phase of Enbridge and Meta’s joint “Cowboy Project.” Once operational, it will deliver power to Meta’s regional data centers through Cheyenne Light, Fuel, and Power under Wyoming’s Large Power Contract Service tariff.
This tariff, originally developed in collaboration with Microsoft and Black Hills Energy, is designed specifically for large loads like data centers. It ensures that the renewable supply serves hyperscale customers without impacting retail electricity rates for other users.
The battery system will operate under a long-term tolling agreement, providing dispatchable capacity that enhances grid reliability. During periods of high demand, the utility can access the backup generation, addressing one of the key challenges of integrating large-scale renewables with the explosive growth of data center electricity demand driven by artificial intelligence.
This latest collaboration builds on prior joint efforts between Enbridge and Meta in Texas, including the 600 MW Clear Fork Solar, 152 MW Easter Wind, and 300 MW Cone Wind projects. Together with the Wyoming initiative, the companies have now partnered on roughly 1.6 gigawatts (GW) of combined solar, wind, and storage capacity.
The deal highlights the intensifying demand for reliable, low-carbon power from technology giants. Meta has committed to supporting its data center growth with renewable energy, joining peers like Microsoft and Google in seeking large-scale solutions. Enbridge’s Allen Capps described the project as “one of the larger utility-scale battery installations supporting U.S. data center operations and growth.”
The involvement of Tesla’s battery technology adds an intriguing layer, linking two of the world’s most prominent tech leaders—Zuckerberg and Musk—in the clean energy transition.
As data centers continue to drive unprecedented electricity load growth across the United States, projects like this one illustrate how hyperscalers are turning to strategic partnerships with traditional energy players and innovative storage solutions to meet both sustainability goals and reliability needs.

Why SpaceX just made a $60 billion bet on AI coding ahead of historic IPO
SpaceX has secured an option to acquire Cursor AI for $60 billion ahead of its historic IPO.
SpaceX announced today it has struck a deal with AI coding startup Cursor, securing the option to acquire the company outright for $60 billion later this year, while committing $10 billion for joint development work in the interim. The announcement described the partnership as building “the world’s best coding and knowledge work AI,” and comes just days after Cursor was separately reported to be raising $2 billion at a valuation above $50 billion.
The move makes strategic sense given where each company currently stands. Cursor currently pays retail prices to Anthropic and OpenAI to the same companies competing directly against it with Claude Code and Codex. That means every dollar of revenue Cursor earns partially funds its own competition. With SpaceX bringing computational infrastructure to the Cursor platform, that could reduce Cursor’s dependence on OpenAI and Anthropic’s Claude AI as its providers. Access to SpaceX’s Colossus supercomputer, with compute equivalent to one million Nvidia H100 chips, gives Cursor the infrastructure to run and train its own models at a scale it could never afford independently. That one change restructures the entire unit economics of the business.
Elon Musk teases crazy outlook for xAI against its competitors
Cursor’s $2 billion in annualized revenue and enterprise reach across more than half of Fortune 500 companies gives SpaceX something its xAI subsidiary currently lacks, which is a proven, fast-growing software business with real enterprise distribution.
For Cursor, SpaceX’s $10 billion in joint development funding is transformational. Cursor raised $3.3 billion across all of 2025 to reach that $2 billion in revenue. A single $10 billion commitment from SpaceX, even as a development payment rather than an acquisition, dwarfs everything Cursor has raised in its entire existence. That capital accelerates product development, enterprise sales infrastructure, and proprietary model training simultaneously.
The timing is deliberate. SpaceX filed confidentially with the SEC on April 1, 2026, targeting a June listing at a $1.75 trillion valuation, in what would be the largest public offering in history. The company is expected to begin its roadshow the week of June 8, with Bank of America, Goldman Sachs, JPMorgan, and Morgan Stanley serving as underwriters. Adding Cursor to the portfolio before that roadshow gives IPO investors a concrete enterprise software revenue story to price in, alongside rockets and satellite internet.
The deal also addresses a weakness that became visible after February’s xAI merger. Several xAI co-founders departed following that acquisition, and SpaceX had already hired two Cursor engineers, signaling where its AI talent strategy was heading. Cursor, for its part, faces a pricing disadvantage competing against Anthropic’s Claude Code.
Whether SpaceX exercises the full acquisition option before its IPO or after remains the open question. Either way, this deal reshapes what investors will be buying into when SpaceX goes public.
