Tesla hints at serious Solar Roof push with roofers’ hiring ramp across the US
Tesla executives like Elon Musk and ardent supporters like legendary billionaire investor Ron Baron have always maintained that the company’s energy department has the potential to be as large, or even larger, than its electric vehicle division. So far, Tesla Energy’s growth has been quite subdued, but there are notable signs that the company is getting serious in ramping its solar and battery storage business.
Among the latest of these signs lie in the mass number of job openings for Solar Roof installers currently active on the company’s Careers page. Based on the listings, Tesla appears to be looking for a large number of Solar Roof installers across the United States, from its home state of California to Texas and all the way to Hawaii. As observed by Tesla investor Warren Redlich in a Twitter post, there seem to be about 100 jobs related to Solar Roof installations currently active as of today.
The Solar Roof, which is currently in its third iteration, is Tesla’s flagship solar product. Solar Roof tiles are quite unique in the way that the tiles have the appearance of regular roofing material, but are capable of functioning as solar panels. This allows customers to enjoy the benefits of a photovoltaic system without compromising the overall aesthetics of their homes. The tiles were initially unveiled in 2016, but due to constant refinements, a ramp of the Solar Roof V3 tiles only started earlier this year.
Yet despite the delays on its ramp, the growth of Solar Roof installations has been notable. In its Q2 2020 Update Letter, Tesla noted that Solar Roof installations have tripled in the second quarter compared to Q1 2020. This is quite notable, especially considering that the United States was dealing with the effects of the pandemic at the time. Considering the number of job listings for Solar Roofers in Tesla’s Careers page today, it appears that the increase in Solar Roof installations will not be subsiding in Q3 2020.
During the second-quarter earnings call, CEO Elon Musk explained that products like the Solar Roof are incredibly pertinent to Tesla’s overall goals. Tesla aims to accelerate the world’s transition to sustainability, and to accomplish this, the company would have to offer products that could enable customers to generate their own power. Conventional solar panels and novel solar shingles like the Solar Roof address this need.
“I think long term, Tesla Energy will be roughly the same size as Tesla automotive. The energy business collectively is bigger than the automotive business. So you say like, how big is the energy sector, big in automotive. And in order to achieve a sustainable energy future, we have to have sustainable energy generation, which I think is going to be primarily solar and — followed by wind. And those are intermittent, so you need to have a lot of batteries to store the energy because wind doesn’t always blow and the sun doesn’t always shine.
“So, there’s like three elements of the sustainable energy future. Wind and solar sustainable energy generation, battery storage, and electric transport. Those three things. And the mission of Tesla is to accelerate sustainable energy. So that kind of says enough. The battery [Indecipherable] will both be enormous and they kind of have to be in order for us to have a sustainable future and we’ve got a great product road map on that front as well,” Musk said.

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.
