Tesla’s solar roof was supposed to revolutionize residential solar energy. Elon Musk introduced the product in 2016 with the promise of beautiful solar shingles that would replace your entire roof, and set a goal of 1,000 new solar roofs per week by the end of 2019. Nearly a decade later, Tesla has installed roughly 3,000 solar roof systems in total, stopped reporting deployment numbers, and is now quietly switching to conventional solar panels.
The gap between the promise of Tesla’s solar roof and reality is one of the clearest examples of unfulfilled ambitions in the company’s history, and has left thousands of customers stuck with an expensive product that Tesla appears to have deprioritized.
The promise versus the numbers
When Musk first unveiled the solar roof in October 2016, he positioned it as a cornerstone of Tesla’s energy future. The proposal was compelling: solar tiles indistinguishable from premium roofing materials, integrated with Powerwalls for whole-home energy independence. Musk claimed it would cost less than a conventional roof plus traditional solar panels. Tesla acquired SolarCity for $2.6 billion in part thanks to this vision, and Musk even said at the time that the SolarCity Gigafactory would produce up to 10 GW/year.
None of that materialized.
Tesla didn’t reach even small-scale production volume until 2020, three years late. At its peak in the second quarter of 2022, Tesla deployed approximately 2.5 MW of solar rooftops per quarter, which is equivalent to about 23 rooftops per week. That’s 97.7% less than the target of 1,000 per week.
According to Wood Mackenzie, Tesla has installed approximately 3,000 solar roof systems in the US through early 2023. Tesla disputed the figure, but never provided its own figure, a telling response.
Then came the silent retreat. Tesla’s solar deployments across all products (solar panels and roof combined) declined for at least four consecutive quarters after Q4 2022. In Q1 2024, Tesla stopped reporting solar deployment numbers entirelysimply removing the item from your quarterly report. The company acknowledged that energy generation and storage revenue increased, driven by Megapack deployments, “partially offset by a decrease in solar deployments.”
Since then, Tesla has virtually stopped mentioning solar shingles.
Customer experience
For current solar roof owners, the situation is arguably worse than the deployment numbers suggest.
Tesla has largely abandoned direct installation of solar roofs. The company no longer offers online quotes for Solar Roof and instead directs customers to third-party certified installers – a small network of regional roofing contractors. in florida, Tesla has completely canceled solar projectsand field workers report that all available equipment is dedicated to repairs, leaving no resources for new installations.
The third-party installer model creates a structural problem for consumers: when something goes wrong, the installer blames Tesla’s design, Tesla blames the installer, and the customer is caught in the middle.
Complaints about customer service are widespread and consistent. Tesla Energy is rated 2.6 out of 5 on SolarReviews, and forums like Reddit’s r/TeslaSolar, Tesla Motors Club, and Bogleheads are filled with reports of months-long service waits, no-show appointments, and unreachable support teams. A Bogleheads user described that Tesla has only one authorized third-party installer in all of Los Angeles.
Company-wide layoffs in 2024 will hit the solar division hard. tesla 285 employees laid off at Buffalo factory as part of a 14% reduction in workforce, and service and support functions were clearly eliminated, explaining the collapse in customer service responsiveness.
There are also unresolved product issues. Tesla’s solar roof uses string inverters rather than microinverters or power optimizers, meaning that partial shading on any section of the roof can stop production of that entire string. This is a major design limitation that competing solar installers address with panel-level optimization technology from companies like Enphase and SolarEdge. Solar Roof owners have reported that the systems are underperforming contracted estimates by 20% or more, and Tesla has reportedly denied some service requests, attributing poor performance to “low usage and weather conditions.”
The economy never worked either. An average Tesla solar roof costs about $106,000 before incentives, compared to about $60,000 for a traditional roof replacement plus conventional solar panels, a $46,000 premium. The payback period extends to 15-25 years, compared to 7-12 years for traditional panels. In 2023, Tesla settled class action lawsuit for $6 million after Customers accused the company of changing prices.and one plaintiff saw the contracted price jump from $72,000 to $146,000.
Tesla’s silence says it all
Perhaps the most telling indicator is Tesla’s own marketing behavior. A search on Tesla’s official X account shows that the last post dedicated to the solar roof was on June 23, 2023 – almost two years ago. Since then, the only mention was a passing vignette in a June 2024 recap thread about “achievements since 2018.”
Tesla regularly promotes Powerwall, Megapack and its new solar panels on social media. Solar Roof has been deleted from marketing.
On earnings calls, Solar Roof barely registers. When Tesla VP of Power Engineering Michael Snyder announced a new residential solar product during the third-quarter 2025 earnings call, it was a conventional panel, the TSP-420, not a solar roof upgrade. The language was carefully chosen: “industry-leading aesthetics” that echo Solar Roof’s marketing, but apply to a standard panel mounted on existing roofs.
The pivot towards the panels
Tesla’s actions make the strategic shift clear. The company launched the TSP-420 panel assembled at Gigafactory New York in Buffalo in early 2026, with a patented 18-zone power optimization system, ironically addressing the shading issue plaguing Solar Roof’s string inverter architecture.
In January 2026, Musk announced in Davos that Tesla aims to build 100 GW per year of solar manufacturing capacity in the United States. Tesla is reportedly in talks to purchase $2.9 billion of Chinese solar equipment to achieve this goal, primarily from Suzhou Maxwell Technologies. A Tesla job posting confirms the goal: “100 GW of raw materials solar manufacturing on US soil by the end of 2028.”
To put it in perspective, total US solar installations in 2023 reached around 32 GW. Currently, Tesla has approximately 300 MW of annual capacity in Buffalo. The 100 GW target represents a 300-fold increase in less than three years and should obviously be taken with caution.
The company also announced it would expand its solar equipment for the first time in five years and launched a new solar leasing product to take advantage of what it sees as a surge in residential demand.
All of this is conventional panel manufacturing. No solar roof tiles.
Electrek’s opinion
I really feel like this product could have worked, but Tesla dropped the ball. Tesla sold thousands of customers a vision of integrated solar shingles that would be the last roof they would ever need. The reality, for many, has been poor performance relative to contracted estimates, a customer service infrastructure shattered by layoffs, and a company that has clearly moved on to its next big project while existing customers are left managing systems that need support that Tesla doesn’t provide.
The move towards conventional panels is probably the right business decision. The panels are cheaper to manufacture, faster to install and the economics really benefit consumers. The TSP-420’s 18-zone optimization system even solves the shading problem that Solar Roof’s string inverter architecture cannot solve. And if Tesla actually achieves even a fraction of its 100 GW manufacturing ambition, it could significantly accelerate solar deployment in the United States.
But that doesn’t change the fact that Tesla made specific promises to Solar Roof customers (about production levels, energy independence, durability) and has quietly walked away from those commitments without publicly acknowledging what went wrong. The company stopped reporting numbers when it became embarrassing, transferred facilities to third parties, and redirected its energy team to an entirely different product. Solar Roof isn’t officially dead, but it has been left to fade away as Tesla chases its next headline.
Whether you’re considering a solar roof, conventional panels, or a home battery pack, the first step is to get competitive solar quotes. With electricity rates increasing nearly 10% last year and expected to continue rising, solar energy is one of the best ways to protect yourself against rising costs. And with leasing and PPA options, you can do it with no upfront cost and start saving right away. If you want to find the best offer, consult energywise. It’s a free service with hundreds of pre-vetted installers competing for your business, so you save 20-30% compared to going it alone. No sales calls until you choose an installer.
