Tesla Solar Roof tile production begins at Gigafactory 2, customer installs soon to follow
Tesla has begun production of its highly-anticipated Solar Roof tiles from the company’s Gigafactory 2 facility in Buffalo, NY. According to an email sent by Tesla, production of the photovoltaic glass roof tiles began last month and the company expects first customer installations to begin in the following months.
The announcement made by Tesla follows a series of production delays, since CEO Elon Musk first unveiled the company’s glass roof tiles more than a year ago. Tesla initially expected the rollout of the solar shingles to begin in 2017, with the manufacturing of the first two types of tiles — smooth and textured — to start during summer. Due to unforeseen delays, however, the mass production and installation of the shingles was ultimately pushed back, first to late 2017, and later, to 2018.
Over the past few months, several sightings of Solar Roof installations were observed by the Tesla community. These installations, however, turned out to be exclusive only to select employees of the California-based electric car and energy company. The glass solar roof tiles were being manufactured in Tesla’s Fremont factory at the time, a facility that is, while capable, unable to produce tiles on the same pace and scale as Gigafactory 2.
For the most part, Tesla has been fairly silent about the progress of its Solar Roof production. There were signs that a ramp-up was happening, such as solar cell manufacturer Panasonic opening new jobs for product expansion, as well as our report on a Tesla patent featuring an adhesive that can conduct electricity through the solar tiles. With Tesla’s recent announcement, however, the timeline for Solar Roof installations has become significantly clearer.
If any, the fact that the Solar Roofs are now being manufactured in Gigafactory 2 means that the photovoltaic tiles are rolling off the production line faster than ever. This ramp-up seems to be well within Tesla CEO Elon Musk’s expectations. Musk, after all, stated in a 2016 interview that he believes the 1.2 million-square-foot Buffalo, NY facility is capable of potentially producing up to 10 gigawatts of solar products every year.

Bloomberg New Energy Finance analyst Hugh Bromley believes that the Solar Tiles’ appeal will not only be limited to the United States, as other countries such as Australia might prove to be lucrative markets for the Silicon Valley-based energy company.
“It may actually do well in overseas markets where solar-photovoltaic is cheap, and homeowners are used to paying a premium for building materials and cars — such as Australia,” Bromley said in an email, according to a Bloomberg report.

Tesla’s Solar Roof tiles are quite unique in the way that they are both functional and aesthetically pleasing. Developed in collaboration with SolarCity, the Solar Tiles look almost indistinguishable from conventional roof tiles despite featuring a full-fledged solar panel. Being constructed from tempered glass, the tiles are pretty durable too, capable of surviving impacts that would otherwise compromise traditional roof materials like terracotta and slate. Paired with Tesla’s Powerwall 2 unit, the Solar Roof has the potential to give customers true independence from conventional power grids.

Tesla launches first Virtual Power Plant in UK – get paid to use solar
Tesla has launched its first-ever Virtual Power Plant program in the United Kingdom.

Tesla has launched its first-ever Virtual Power Plant program in the United Kingdom. This feature enables users of solar panels and energy storage systems to sell their excess energy back to the grid.
Tesla is utilizing Octopus Energy, a British renewable energy company that operates in multiple markets, including the UK, France, Germany, Italy, Spain, Australia, Japan, New Zealand, and the United States, as the provider for the VPP launch in the region.
The company states that those who enroll in the program can earn up to £300 per month.
Tesla has operated several VPP programs worldwide, most notably in California, Texas, Connecticut, and the U.S. territory of Puerto Rico. This is not the first time Tesla has operated a VPP outside the United States, as there are programs in Australia, Japan, and New Zealand.
This is its first in the UK:
Our first VPP in the UK
You can get paid to share your energy – store excess energy in your Powerwall & sell it back to the grid
You’re making £££ and the community is powered by clean energy

Tesla is not the only company that is working with Octopus Energy in the UK for the VPP, as it joins SolarEdge, GivEnergy, and Enphase as other companies that utilize the Octopus platform for their project operations.
It has been six years since Tesla launched its first VPP, as it started its first in Australia back in 2019. In 2024, Tesla paid out over $10 million to those participating in the program.
Participating in the VPP program that Tesla offers not only provides enrolled individuals with the opportunity to earn money, but it also contributes to grid stabilization by supporting local energy grids.

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.
