Tesla Solarglass Roof: LA-based homeowner shares first impressions of V3 roof tiles
As the cost of installing solar drops in the United States by as much as 70% in the last decade, more and more homeowners in the US are considering a switch to greener energy. At the forefront of Tesla’s push into residential solar is its flagship Solarglass roof, which are essentially solar cells that look like standard roofing tiles. Yet, inasmuch as Tesla’s Solarglass tiles have caught numerous headlines in the past, many questions about the product, such as its durability, installation process, and real cost, remain.
Los Angeles, California-based Austin Flack is one of the first consumers to get a Tesla Solarglass Roof. In a recent video shared on YouTube, Flack decided to share his first impressions about his Tesla Solarglass experience.
“We placed our order in early November and were scheduled for installation in mid-December, but rainy weather pushed installation into January. Unfortunately, the federal rebate fell from 30% in 2019 to 26% in 2020, but Telsa was kind enough to give us a 4% discount to make up the difference,” Flack wrote on the description of his review on YouTube.
COST OF TESLA SOLARGLASS ROOF
Prior to the announcement of Tesla about the latest version of the company’s flagship solar product in October 2019, Flack and his wife thought of getting Tesla solar panels but they discovered that their roof, which measures 1,745 sq.ft., wasn’t properly designed and installed.
The couple decided to compare the cost of getting a new composite roof plus the Tesla solar panel array they need. Estimates for the composite tile roof ranged roughly between $9,000 and $12,000. Meanwhile, Tesla calculated that their Los Angeles home would need a system size of around 9.087 kW with some room for energy needs to grow. The quote from Tesla for the Solarglass Roof is $33,749 after rebates. This price is about $3,000 more expensive than the cost of getting a composite tile roof with the equivalent solar panel array setup.
According to Flack, they went for the Solarglass Roof and found the price reasonable “given the enhanced aesthetics of solar glass and how much value it might add to our home.”
SOLARGLASS ROOF INSTALLATION
Installation of the Solarglass Roof started on Jan. 6 and took 7 days including removal of the old roof, installation of Solarglass tiles, replacement of other roofing elements, and hardware setup.
Flack shared that their new roof is mostly solar tiles with some dummy tiles for the edges and to fit near the vents and pipes. The roof was also raised by about 1.5 inches to have some space for wiring and ventilation.
From the solar tiles, Tesla neatly installed conduit boxes in their attic and directed the power to a DC inverter, shutoff switches, and 200 amp electrical box.
The couple is still waiting for the final approval to turn on the system and promised to post an update video once it’s online.
“For now, we are very happy with the Solar Glass. It’s beautiful. It’s durable. It’s guaranteed for 25 years, and when fully operational it will completely zero out our electrical bill,” Flack said.
TESLA SOLAR ENERGY BUSINESS WILL SHINE IN 2020
Tesla’s solar business had its moments under the cloud and seemingly losing its shine amid rising competition from smaller solar roof installers and lower subsidies for solar panels. With the solar business’ back on the wall, Elon Musk re-aligned and reignited Tesla’s solar push with the promise to ramp up production and aim to install more solar roofs compared to previous years. Musk showed a more cautious side and for most, that was a good thing.
“In the long term, I expect Tesla Energy to be of the same or roughly the same size as Tesla’s automotive sector or business. This is the most underappreciated group. I think it could be bigger, but it’s certainly of a similar magnitude to Tesla Solar. Meaning, if you take Tesla Solar plus battery stuff, Tesla Energy is, I think, the least appreciated element,” Musk said.
At present, Tesla offers $250-incentive for new customers and for people who will refer other buyers.
In December, Tesla also installed canopies for their solar test houses in its Fremont factory, reminiscent of how it used big tents to solve Model 3 production issues. During the same period, Tesla looked to hire more installers to beef up its teams in California, Texas, Nevada, and Florida. In Q3 of 2019, the company deployed about 43MW of solar, about 48% more compared to Q3.

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.
