Elon Musk promised 1,000 Tesla Solar Roofs installed every week by the end of 2019. According to Wood Mackenzie data cited by Electrek, the running US total through early 2023 was around 3,000 units. Tesla disputed the figure but has never released its own. In the first quarter of 2024, the company removed the solar deployment line item from its quarterly reports entirely.

That gap — between a number Tesla broadcast in 2016 and a number it has stopped acknowledging — is the public face of what Electrek’s Fred Lambert this week described as Solar Roof being “on life support” while the company pivots to conventional panels. For Tesla owners, the consequence is structural. Solar Roof was the piece that was supposed to close the loop. Tiles on the house, Powerwall in the garage, a Model Y or a Cybertruck plugged into both. With the tiles fading out, that loop now runs through any installer with a forklift and a pallet of panels.

None of this is being announced. There has been no product end-of-life statement, no formal discontinuation, no press release. The retreat shows up instead in what Tesla has stopped doing: stopped quoting Solar Roof online for new buyers, stopped staffing its own installation crews, stopped publishing deployment figures, and, since June 23, 2023, stopped posting about Solar Roof on its corporate X account altogether.

The numbers Tesla stopped reporting

When Musk first presented Solar Roof in October 2016, Tesla had just announced its $2.6 billion acquisition of SolarCity. The pitch tied the two together: integrated solar tiles indistinguishable from premium roofing, mated to Powerwall storage, mated to a Tesla vehicle in the driveway. Musk said at the time that the new Buffalo plant — Gigafactory New York — would scale to 10 GW per year of solar production.

Volume production did not begin until 2020, three years late. At its peak in Q2 2022, Tesla deployed roughly 2.5 MW of Solar Roof per quarter. At an average system size of about 9 kW, that works out to around 23 installations per week, or 97.7 percent below the 1,000-per-week target Musk had set in 2016. After Q4 2022, total Tesla solar deployments — panels and Solar Roof combined — declined for four consecutive quarters, according to a CleanTechnica analysis cited by Electrek. Then Tesla took the line off the books.

The Q1 2024 shareholder letter no longer broke out solar deployments. The disclosure was folded into a generic line about energy generation and storage revenue being driven by Megapack, “partially offset by a decrease in solar deployments.” Megapack is Tesla’s utility-scale stationary battery product. It has nothing to do with residential rooftops.

What broke for existing customers

The Solar Roofs that did get installed have aged into a service problem. Tesla’s roof tiles use a string-inverter architecture, the older topology common in entry-level solar arrays a decade ago. The trade-off is well known: partial shading on one section of the roof — a tree branch, a chimney, even a row of leaves — can throttle production across the entire string. Competing residential solar installers route around this with module-level optimizers from companies like Enphase Energy and SolarEdge Technologies. Tesla never did.

Owners on Reddit’s r/TeslaSolar, on Tesla Motors Club, and on the Bogleheads forum have reported systems generating 20 percent or more below the values written into their original contracts. Tesla Energy holds a 2.6 out of 5 rating on SolarReviews. Electrek noted that one Bogleheads user reported a single authorized third-party Solar Roof installer covering the entire Los Angeles metro area. In Florida, Tesla canceled in-flight Solar Roof projects outright and reassigned remaining field capacity to warranty repairs.

The April 2024 companywide layoffs — which Bloomberg reported at 14 percent of Tesla’s workforce — hit Gigafactory New York hard. Tesla cut 285 employees in Buffalo as part of that reduction, and customer-facing solar functions absorbed most of the damage. The financial fallout had already arrived a year earlier. In July 2023, Tesla settled a class-action lawsuit for $6 million over Solar Roof pricing changes. The lead plaintiff had been quoted $72,000 at signing. The final invoice came in at $146,000.

The TSP-420 and the 100 GW pivot

In January 2026, Tesla launched the TSP-420, a US-assembled conventional solar panel built at the same Buffalo plant that was supposed to scale Solar Roof to a gigawatt cadence. The panel uses an 18-zone power optimization architecture — three times the granularity of a conventional panel — designed to keep producing under partial shade. That is the same problem Solar Roof’s string-inverter design has never solved.

The pivot was formalized on March 6, 2026, when Tesla published the “Introducing Tesla Solar Panels” page on its own site. The marketing copy borrows directly from Solar Roof’s playbook: all-black cells, concealed electrical connections, low-profile skirt to hide hardware. The product, however, is a panel mounted on top of an existing roof. There is no tile.

Then came the scale claim. At the World Economic Forum in Davos in January 2026, Musk announced that Tesla and SpaceX would each independently build 100 GW per year of US solar manufacturing capacity by the end of 2028, covering the supply chain from raw materials to finished panels. A Tesla job posting later confirmed the language: “100 GW of solar manufacturing from raw materials on American soil before the end of 2028.” Tesla is reportedly in talks to fund the buildout in part with $2.9 billion in Chinese solar equipment from Suzhou Maxwell Technologies, a contradiction Electrek flagged in its own reporting.

The math is steep. Total US solar installations across all manufacturers reached around 32 GW in 2023, the most recent full-year benchmark. Buffalo today runs at about 300 MW of annual capacity. First Solar, currently the largest domestic solar manufacturer, projects 17.7 GW of capacity by 2027. Tesla’s 100 GW target represents roughly a 300-fold increase over current Buffalo output in under three years and would, on its own, exceed the entire US installation rate of 2023 by a factor of three.

The ecosystem Tesla is quietly trimming

Solar Roof is not the only Tesla product retreating below the noise floor. The Cybertruck Long Range — the rear-wheel-drive trim Tesla launched in April 2025 as the affordable version of its angular pickup — moved just 173 units before Tesla quietly canceled production in November 2025. That number became public earlier this month through an NHTSA recall covering all RWD Cybertrucks with 18-inch steel wheels. The recall paperwork was filed because the rotors could crack. The accidental disclosure was the sales volume.

The pattern is consistent. Tesla launched a stripped-down Cybertruck to address a price ceiling and pulled it after a single-digit production run. Tesla launched Solar Roof to address residential aesthetics and pulled back to commodity panels after roughly 3,000 installs. Both products were pitched as ecosystem closers. Both ended up as line items the company stopped highlighting.

For the EV owner who bought into the original Tesla pitch — a closed loop running from rooftop generation to home storage to vehicle charging — the closed part is what is going away. The Powerwall still exists. The vehicles still exist. The Supercharger network has expanded. The roof, however, is now something Tesla sells you using the same hardware approach as any third-party installer. The TSP-420 is a competitive panel. It is not a Tesla product in the way Solar Roof was meant to be a Tesla product.

Where this leaves the buyer

For prospective customers, the calculus is simpler than it has been in a decade. Solar Roof is still listed on Tesla’s website, but new buyers in most US markets are routed to a thin layer of third-party certified installers who carry the warranty risk Tesla has stepped back from. New residential solar dollars from Tesla itself now flow toward the TSP-420 and whatever follows it.

For existing Solar Roof owners, the service path is the one Electrek documented this week: third-party installers handling Tesla-engineered hardware, regional capacity constraints, and underperformance complaints that the company has at times attributed to “low usage and weather conditions.” That is a customer-service framing common in mature solar businesses. It is not the framing Tesla used in 2016, when the entire product was sold as a single integrated promise.

None of this changes the fundamental case for residential solar in the US. Rooftop generation paired with home storage continues to make economic sense in most state markets, especially with electricity rates climbing close to 10 percent year-over-year in 2025. What changes is that the customer pursuing that economics no longer needs to wait for a Tesla-branded tile. They can buy a panel from anyone — including Tesla, on the same terms as everyone else.

Musk pitched Solar Roof in 2016 as the piece that would make SolarCity make sense. Ten years later, the SolarCity factory is producing a conventional panel and chasing a 100 GW target that, on the current trajectory, would require building more new manufacturing capacity in three years than the entire United States installed in 2023. The Solar Roof itself is not officially dead. It has simply been left to a customer support queue while Tesla writes a different headline.
