Tesla Energy’s quick installs hint at ongoing residential solar and Powerwall ramp
It appears that Tesla Energy’s highly-anticipated ramp is picking up some speed. With Model 3 production humming at levels that allow the company to begin distributing the all-electric sedans to international markets, the company seems to be intent in gaining back some momentum in the United States’ residential solar market, a segment that was, at one point, dominated by SolarCity.
Tesla Model 3 owner Nick Wood and his family had been looking to add solar panels and a home battery system to their house in Santa Rosa, CA. The home had been affected by the 2017 wildfires, and PGE had advised residents in the area that there will be power interruptions during windy, dry conditions. With the family being all-in on electric vehicles — a Tesla Model 3 and two Chevy Bolts under a lease — the Woods needed a way to achieve power independence from the grid.
The family filed applications for two projects: one for their main house with about 40 kW of solar panels and five Powerwall units, and another for a second house with 8.2 kW of solar and two Powerwalls. Both applications were filed around June 10. Following a site visit and once the loan terms and other financials of the project were approved, Tesla informed the family that the first Powerwall and solar panels were set to be installed on July 2. That was just over three weeks since the system was ordered.
@Tesla @elonmusk @ElectrekCo @Teslarati @ValueAnalyst1 Tesla solar easy as ordering a car 3 weeks from order to install, less than cost of power per month. Looks like 2 power walls and 26 panels will be installed in 1 day. Longer to get county/PGE sign off

The Tesla installers arrived at around 9 a.m. on the day of the installation. The team worked simultaneously, with some working on trenches for the system’s power connections, others setting up the Powerwalls, and the rest installing the solar panels. Much to the Woods’ appreciation, the entire project was fully completed before the end of the day. The team even set up two electric car chargers at no extra cost. The Tesla team also gave the Woods their email addresses so that they could forward any pertinent information about the site to the installers of the main house’s upcoming 40 kW solar panels and five Powerwalls.
In a message to Teslarati, Nick Wood mentioned that the installers had been finishing around one Tesla Energy project per day. The installers also stated that they have been particularly busy as of late, with an appointment with a residential solar and/or Powerwall customer being scheduled daily. Quite notably, Wood stated that his family now has to wait around 1-5 weeks for the county inspection so that they can activate the system. That’s potentially longer than the time it took for the solar panels and Powerwalls to be ordered and installed.

Granted, part of the reason behind the quick turnaround time of the Woods’ residential solar installation could be their location. Being in California, the family lives in a state that is heavily saturated by Tesla. Nevertheless, the efficiency exhibited by the installers, as well as the team’s mention of busy weeks filled with project after project, hints at a ramp in the company’s Energy initiatives.
This bodes well for Tesla’s residential solar business, which has seen a decline since the company acquired SolarCity in 2016. Since SolarCity’s peak of commanding 32.6% of the US market in 2014, Tesla’s presence in the country’s residential solar segment as shrunk, hitting only 6.3% during Q1 2019. Nevertheless, hints of a potential ramp started emerging last year, when Tesla started dramatically reducing its customer acquisition costs by spending only $0.40 per watt to acquire customers. This is far lower than competitors such as Vivint, which has customer acquisition costs of $0.94 per watt, and Sunrun, whose costs run at $0.90 per watt.
Tesla Energy is pretty much a sleeping giant for now. The business has so far been away from the spotlight, especially amidst the production ramp of the Model 3, but it has a lot of potential. Legendary investor Ron Baron, for one, has estimated that Tesla Energy on its own could be worth $500 billion. Elon Musk and the company’s executives, for their part, have noted that a ramp in Tesla Energy’s activities is underway, with the CEO stating during the unveiling of the Model Y that 2019 will be the “Year of the Solar Roof and Powerwall.”

Zuckerberg’s Meta taps Musk’s Tesla for massive clean energy project
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.

Tesla Supercharger for Business exposes jaw-dropping ROI gap between best and worst locations
Tesla’s new Supercharger for Business calculator reveals an eye-opening all-in cost and location-based ROI projections.
Tesla has launched an online calculator for its Supercharger for Business program, giving property owners their first transparent look at what it really costs to install Superchargers on site and what kind of return they can expect.
The program itself launched in September 2025, allowing businesses to purchase and operate Supercharger hardware on their own property while Tesla handles installation, maintenance, software, and 24/7 driver support. As Teslarati reported at launch, hosts also get their logo placed on the chargers and their location integrated into Tesla’s in-car navigation, meaning drivers are actively routed there. The stalls are open to all EVs, not just Teslas.
We launched Supercharger for Business in 2025 to help companies get charging right. We found simplicity and transparency to be a problem in this industry.
We’re now sharing pricing and a financial calculator to help make informed decisions. The goal is to accelerate investments,…
— Tesla Charging (@TeslaCharging) April 8, 2026
The new online calculator, announced by Tesla on Wednesday with the note that “simplicity and transparency” have been a problem in the industry, lets any business enter a U.S. address and get a real cost and revenue model. A standard 8-stall V4 Supercharger site runs approximately $500,000 in hardware and $55,000 per post for installation, bringing an all-in price just shy of $1 million. Tesla charges a flat $0.10 per kWh fee to cover software, billing, and network operations. Businesses set their own retail price and keep the margin above that fee.
Taking a look at Tesla’s Supercharger for Business online calculator, we can see that ROI is not uniform, and the gap between a strong location and a poor one can stretch the breakeven point by several years.
The biggest driver is foot traffic and how long people stay. A busy rest station, hotel, or outlet mall brings in repeat visitors who need to charge while they’re already stopped, pushing utilization numbers higher and shortening payback time.
Local electricity rates matter just as much on the cost side. Markets like California carry some of the highest commercial electricity rates in the country, which eats into the margin between what a host pays per kWh and what they charge drivers. At the same time, dense urban areas with high EV adoption tend to support higher retail charging prices, which can offset that cost if demand is strong enough. Weather also plays a role. Cold climates reduce battery efficiency and increase charging frequency, but they can also suppress utilization in winter months if drivers avoid stopping in exposed outdoor locations. Suburban and rural sites face a different problem: lower baseline EV traffic, which means a site with cheaper power and lower operating costs can still take longer to pay back simply because the stalls sit idle more often. Tesla’s calculator uses real fleet data to pre-fill utilization estimates by ZIP code, so businesses can run their specific address against these variables rather than relying on averages.
The program has seen real adoption. Wawa, already the largest host of Tesla Superchargers with over 2,100 stalls across 223 locations, opened its first fully owned and branded site in Alachua, Florida earlier this year. Francis Energy of Oklahoma and the city of Alpharetta, Georgia have also deployed branded stations through the program, as Teslarati covered in January.
Tesla now exceeds 80,000 Supercharger stalls worldwide, and the calculator makes the economic case for accelerating that number through private investment rather than company-owned sites alone.
