GoKawiilTesla’s Solar Roof was supposed to revolutionize residential solar. Elon Musk unveiled the product in 2016 with the promise of beautiful solar tiles that would replace your entire roof — and he set a target 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 total, stopped reporting deployment numbers, and is now quietly pivoting to conventional solar panels.
The gap between Tesla’s Solar Roof promise and reality is one of the most stark examples of unfulfilled ambitions in the company’s history — and it has left thousands of customers stuck with an expensive product that Tesla appears to have deprioritized.
The promise vs. the numbers
When Musk first presented the Solar Roof in October 2016, he positioned it as a cornerstone of Tesla’s energy future. The pitch 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 partly on the strength of this vision, and Musk even said at the time that SolarCity’s Gigafactory would produce up to 10 GW/year.
None of that materialized.

Tesla didn’t reach even small-scale volume production until 2020 — three years behind schedule. At its peak in Q2 2022, Tesla deployed approximately 2.5 MW of Solar Roofs per quarter, equivalent to about 23 roofs per week. That’s 97.7% short of the 1,000-per-week target.
According to Wood Mackenzie, Tesla installed roughly 3,000 Solar Roof systems in the US through early 2023. Tesla disputed the figure but never provided its own number — a telling response.
Then came the quiet retreat. Tesla’s solar deployments across all products (panels and Solar Roof combined) declined for at least four consecutive quarters after Q4 2022. In Q1 2024, Tesla stopped reporting solar deployment figures entirely, simply removing the line item from its quarterly report. The company acknowledged energy generation and storage revenues were up, driven by Megapack deployments, “partially offset by a decrease in solar deployments.”
Since then, Tesla has virtually stopped even mentioning the solar roof tiles.
