Elon Musk makes opening remarks in SolarCity trial, defends Tesla’s $2.6B acquisition
Elon Musk has made his opening remarks in a Wilmington, Delaware, courthouse on Monday morning, defending Tesla’s $2.6 billion acquisition of solar energy company SolarCity. The deal took place in 2016 and gave Tesla full possession of the solar panel maker, a move that some Tesla shareholders were not keen on, as some are alleging the move was a bailout of SolarCity.
The lawsuit indicates that Musk applied heavy pressure on Tesla’s board to purchase SolarCity back in 2016, as the company was running low on cash and was likely headed for bankruptcy. Musk owned a 22% stake in SolarCity at the time of Tesla’s acquisition. Interestingly, Musk also owned around 22% of Tesla at the time of the SolarCity purchase. SolarCity was founded by two of Musk’s cousins, Lyndon and Peter Rive.
Vice Chancellor Joseph Slights will sit in on the two-week trial in Courtroom 7E in the Wilmington Courthouse. He will ultimately decide whether Tesla’s purchase of SolarCity was fair to shareholders.
Musk commented on questions asked by his attorney, Evan Chesler, initially, stating that the nature of the transaction did not result in any monetary gain for him personally. He said (via Reuters):
“Since it was a stock-for-stock transaction and I owned almost exactly the same percentage of both there was no financial gain.”
Tesla shareholders requested that Musk repay Tesla the $2.6 billion price tag for the SolarCity acquisition. If this were to occur, it would be one of the largest judgments ever to be decided against one person. If Judge Slights decides that the acquisition was unfair to Tesla shareholders, he could ultimately decide on another amount, a number that could be much lower than the actual purchase price that Tesla paid.
Musk added that the acquisition of SolarCity was a key component to “Master Plan, Part Deux,” the second faction to the CEO’s “top secret” playbook for transitioning the world to sustainable energy. Additionally, he stated that he did not control the appointment or compensation of SolarCity board members at the time of the acquisition, and he did not influence the deal’s terms. Musk maintains that his relationship with the SolarCity Board of Directors is “good” and that they “work hard and are competent.”
Musk was cross-examined by the shareholder attorney Randy Baron, who told the Tesla CEO that it could be a long two weeks. In typical Musk fashion, he replied, “I can tell by the binder.”
Ultimately, legal experts indicate that Judge Slights will be looking for any sort of evidence that would conclude Musk threatened directors or board members to decide in favor of purchasing SolarCity. Reuters said in its coverage of the trial that one of the turning points of the trial will be allegations that Musk was a controlling shareholder. If this can be proven, it would likely imply that the deal was unfair to shareholders and could impose tougher legal implications for the CEO.
Slights will not decide Musk’s fate at the tail-end of the trial. A verdict will likely come months down the road after plenty of deliberation.

Tesla Lathrop Megafactory celebrates massive Megapack battery milestone
The Tesla Megapack is the backbone of Tesla Energy’s battery deployments.
The Tesla Lathrop Megafactory recently achieved a new milestone. As per the official Tesla Megapack account on X, the Lathrop Megafactory has produced its 15,000th Megapack 2 XL battery.
15,000 Megapack Batteries
Tesla celebrated the milestone with a photo of the Lathrop Megafactory team posing with a freshly produced Megapack battery. To commemorate the event, the team held balloons that spelled out “15,000” as they posed for the photo.
The Tesla Megapack is the backbone of Tesla Energy’s battery deployments. Designed for grid-scale applications, each Megapack offers 3.9 MWh of energy and 1.9 MW of power. The battery is extremely scalable, making it perfect for massive energy storage projects.
More Megafactories
The Lathrop Megafactory is Tesla’s first dedicated facility for its flagship battery storage system. It currently stands as the largest utility-scale battery factory in North America. The facility is capable of producing 10,000 Megapack batteries every year, equal to 40 GWh of clean energy storage.
Thanks to the success of the Megapack, Tesla has expanded its energy business by building and launching the Shanghai Megafactory, which is also expected to produce 40 GWh of energy storage per year. The ramp of the Shanghai Megafactory is quite impressive, with Tesla noting in its Q1 2025 Update Letter that the Shanghai Megafactory managed to produce over 100 Megapack batteries in the first quarter alone.
Tesla Energy’s Potential
During the first quarter earnings call, CEO Elon Musk stated that the Megapack is extremely valuable to the energy industry.
“The Megapack enables utility companies to output far more total energy than would otherwise be the case… This is a massive unlock on total energy output of any given grid over the course of a year. And utility companies are beginning to realize this and are buying in our Megapacks at scale,” Musk said.

Tesla Megapacks powers the xAI Colossus supercomputer
Tesla Megapacks step in to stabilize xAI’s Colossus supercomputer, replacing natural gas turbines. Musk’s ventures keep intertwining.
Tesla Megapack batteries will power the xAI Colossus supercomputer in Memphis to ensure power stability. The collaboration between Tesla and xAI highlights the synergy among Elon Musk’s ventures.
The artificial intelligence startup has integrated Tesla Megapacks to manage outages and demand surges, bolstering the facility’s reliability. The Greater Memphis Chamber announced that Colossus, recently connected to a new 150-megawatt electric substation, is completing its first construction phase. This transition addresses criticism from environmental justice groups over the initial use of natural gas turbines.
“The temporary natural gas turbines that were being used to power the Phase I GPUs prior to grid connection are now being demobilized and will be removed from the site over the next two months.
“About half of the operating turbines will remain operating to power Phase II GPUs of xAI until a second substation (#22) already in construction is completed and connected to the electric grid, which is planned for the Fall of 2025, at which time the remaining turbines will be relegated to a backup power role,” the Chamber stated.
xAI’s rapid development of Colossus reflects its ambition to advance AI capabilities, but the project has faced scrutiny for environmental impacts. The shift to Megapacks and grid power aims to mitigate these concerns while ensuring operational continuity.
The Megapack deployment underscores the collaboration among Musk’s companies, including Tesla, SpaceX, Neuralink, and The Boring Company. Tesla appears to be the common link between all of Musk’s companies. For example, The Boring Company built a tunnel in Giga, Texas. In addition, Musk has hinted at a potential collaboration between the Tesla Optimus Bot and Neuralink. And from January 2024 to February 2025, xAI invested $230 million in Megapacks, per a Tesla filing.
Tesla Energy reported a 156% year-over-year increase in Q1 2025, deploying 10.4 GWh of storage products, including Megapacks and Powerwalls. Tesla’s plans for a new Megapack factory in Waller County, Texas, which is expected to create 1,500 jobs in the area, further signal its commitment to scaling energy solutions.
As xAI leverages Tesla’s Megapacks to power Colossus, the integration showcases Musk’s interconnected business ecosystem. The supercomputer’s enhanced stability positions xAI to drive AI innovation, while Tesla’s energy solutions gain prominence, setting the stage for broader technological and economic impacts.

Tesla Energy celebrates one decade of sustainability
Tesla Energy has gone far since its early days, and it is now becoming a progressively bigger part of the company.
Tesla Energy recently celebrated its 10th anniversary with a dedicated video showcasing several of its milestones over the past decade.
Tesla Energy has gone far since its early days, and it is now becoming a progressively bigger part of the company.
Tesla Energy Early Days
When Elon Musk launched Tesla Energy in 2015, he noted that the business is a fundamental transformation of how the world works. To start, Tesla Energy offered the Powerwall, a 7 kWh/10 kWh home battery system, and the Powerpack, a grid-capable 100 kWh battery block that is designed for scalability. A few days after the products’ launch, Musk noted that Tesla had received 38,000 reservations for the Powerwall and 2,500 reservations for the Powerpack.
Tesla Energy’s beginnings would herald its quiet growth, with the company later announcing products like the Solar Roof tile, which is yet to be ramped, and the successor to the Powerwall, the 13.5 kWh Powerwall 2. In recent years, Tesla Energy also launched its Powerwall 3 home battery and the massive Megapack, a 3.9 MWh monster of a battery unit that has become the backbone for energy storage systems across the globe.
Key Milestones
As noted by Tesla Energy in its recent video, it has now established facilities that allow the company to manufacture 20,000 units of the Megapack every year, which should help grow the 23 GWh worth of Megapacks that have already been deployed globally.
The Powerwall remains a desirable home battery as well, with more than 850,000 units installed worldwide. These translate to 12 GWh of residential entry storage delivered to date. Just like the Megapack, Tesla is also ramping its production of the Powerwall, allowing the division to grow even more.
Tesla Energy’s Role
While Tesla Energy does not catch as much headlines as the company’s electric vehicle businesses, its contributions to the company’s bottom line have been growing. In the first quarter of 2025 alone, Tesla Energy deployed 10.4 GWh of energy storage products. Powerwall deployments also crossed 1 GWh in one quarter for the first time. As per Tesla in its Q1 2025 Update Letter, the gross margin for the Energy division has improved sequentially as well.
