Tesla’s Home Battery Offering In Context — Pricing Much Lower Than Expected

think one of the lessons of the day is to trust Elon Musk. When he said approximately a month ago that Tesla would be announcing a “major new product line” on April 30, he wasn’t using the term “major” in a light way. [Full Disclosure: I’m long (very long) TSLA.] […]
