Tesla Solar Roof는 패널로 전환하면서 생명 유지 상태에 놓임

Tesla's Solar Roof has failed spectacularly despite massive R&D investment, achieving just 2.3% of its 1,000-unit-per-week target and prompting the company to pivot to conventional solar panels. The product's fundamental design flaws (string inverter vulnerability to shadows), punishing economics ($106,000 vs $60,000 for standard solar), and deteriorating support have exposed the limits of hardware differentiation when competing against simple, proven alternatives. This retreat from radical innovation to commodity competition signals Tesla's broader struggle: grand visions often collapse under the weight of physics, economics, and service delivery realities.
