Tesla quietly abandons Solar Roof after hitting 0.3% of its weekly install target

Nearly a decade after Elon Musk unveiled the Solar Roof in 2016 with a goal of 1,000 installs per week by end of 2019, Tesla has deployed only around 3,000 systems total. Peak production in Q2 2022 hit roughly 23 roofs per week — 97.7% short of target. Tesla stopped reporting solar deployment figures entirely in Q1 2024, has not posted about Solar Roof on its main social channels since June 2023, and has shifted nearly all installation work to a thin network of third-party contractors.

Existing owners are caught in a familiar squeeze: Tesla blames installers, installers blame Tesla’s design, and a 2024 layoff round that cut 285 Buffalo employees gutted service capacity. The product itself has structural problems — string inverters instead of panel-level optimizers mean partial shading can knock out entire sections, and systems frequently underperform contracted estimates by 20% or more. At roughly $106,000 versus $60,000 for a conventional roof plus panels, the economics never closed, and a $6 million class-action settlement in 2023 covered bait-and-switch pricing claims.

The replacement strategy is now explicit. Tesla’s new TSP-420 conventional panel, assembled in Buffalo, ships with an 18-zone power optimizer that directly addresses the shading flaw in Solar Roof. Musk has floated a 100 GW US manufacturing target by 2028 — a 300x jump from current capacity that warrants heavy skepticism — backed by a reported $2.9 billion in planned Chinese equipment purchases. Solar Roof is not part of that future.
