Yeah and I think that's fine - and as I mentioned below my own reasons for installing solar panels were not just financially motivated. But the economics are also hugely important. Most people don't buy $5,000 tables, and most people don't buy Tesla Solar Roofs - the article says they sold 3,000 total in the last decade. And I don't think Tesla wants to be in the bespoke roof business - they want to be selling to the masses (or at least a sizeable well-off segment of the masses).

It also doesn't help that they seemingly had issues scaling up - and even people who were willing to spend $100K on a Solar Roof faced long delays if they were available at all in their market. Tesla's image has also shifted in the last decade, and having a Tesla parked in your driveway with a powerwall and solar roof doesn't carry quite the same image that it once did - which is important when you are relying on emotions to drive sales.
