This is all great, but...
Elon and company missed an opportunity here to show how this benefits a typical homeowner. I'm not talking about how it's beneficial technically (balancing the grid, storing solar at night, etc.). I'm talking about how it financially benefits a homeowner. They should have had some examples in their presentation about how a typical homeowner could come out ahead by getting this system. It costs me $3500+installation. OK. How much do I save over its lifetime?
Without that aspect, I was left thinking that people who are educated on renewable energy will see the benefits, but the benefits won't translate to the masses. Maybe they don't need it to translate to the masses for a long while, since they will likely be production-constrained for years to come. But regardless, it's a missed opportunity in that respect.
I'd suggest that many in the press will be left with similar questions.
I come away from this thinking that Tesla makes great, world-changing products, but doesn't do a great job presenting them.
