$TSLA quietly killed the solar roof after a decade of hype. Musk pitched it as the future of residential energy, locked in tax credits, scaled Gigafactory Nevada around the bet — then just… stopped. No press release, no pivot explanation, nothing. It wasn't a product. It was a narrative that ran out of road. This is classic Tesla: chase the vision, juice the stock, then ghost the execution when unit economics don't work. Investors funded the dream. Customers got stranded. Meanwhile, the core auto business is facing margin compression, EV competition, and a demand problem Musk won't admit. Solar roof was supposed to be the energy diversification story. Now it's just another abandoned bet in a portfolio that's starting to look more like vaporware than vertical integration.
