Tesla’s solar roof is dead — here’s what went wrong

Tesla has quietly shelved its solar roof tile product after years of sluggish adoption and production struggles. The ambitious concept — replacing traditional roofing with electricity-generating tiles — never achieved meaningful scale. The question now is whether building-integrated photovoltaics as a broader industry concept can survive Tesla's exit.
