Tesla promised 1,000 Solar Roofs/week by 2019, installed ~3,000 total in nearly a decade, and is now pivoting to conventional panels.
Key Takeaways
Peak Solar Roof output was ~23 roofs/week in Q2 2022, 97.7% below Musk’s 1,000/week target.
Tesla stopped reporting solar deployment figures entirely in Q1 2024, removing the line item from quarterly reports.
Average Solar Roof costs ~$106,000 vs. ~$60,000 for a traditional roof plus conventional panels; payback stretches 15-25 years.
String inverter architecture causes full-string shutdowns under partial shading – a flaw the new TSP-420 panel addresses with 18-zone optimization.
Tesla’s new focus is the TSP-420 panel and a stated 100 GW/year US manufacturing target, representing a 300x increase from current ~300 MW Buffalo capacity.
Hacker News Comment Review
Commenters are skeptical rather than analytical: discussion leans toward cynicism about Tesla’s motives and execution quality rather than technical dissection.
One commenter suggests Solar Roof was introduced primarily as a stock-pump during a weak financial period for Tesla, framing it as a marketing vehicle rather than a serious product roadmap.

@winfredJa: argues Solar Roof was a financial distraction tool, not a genuine product commitment.
