the cool thing is that they look good... they look like a normal roof at the angle you would see from the street in front of the house, but from above... from the angle of the sun they are transparent and you can see the solar cells.

This product strategy certainly seems easy to copy, I agree. That's good for humanity and bad for Elon financially (I think that's the point for him, I don't think he cares about money outside of more commas).

The product itself might be easy to copy, but im not so sure about the product *strategy". Solarcity does the full stack, from the solar panels to the installation to the management and storage. That's going to be hard for a Chinese factory to reproduce.

How long are the batteries going to last? With phones, we expect the battery to deteriorate after a couple of years. This is an investment. Will it need to be replaced in a few years' time?

Tesla automotive batteries have shown pretty strong resilience over the few years they have been running, even on cars that have been driven hard.

Cars are at >90% capacity after 50,000 miles. It's not like the batteries need to be replaced frequently.

I wonder if these Powerwalls will have the same sophisticated battery thermal management system as the cars?

I'm interested in both but could not find any details what kind of output a solar roof would generate.

Also, I would be interested in know if it's possible to walk on top of a solar roof. People still need to be able to get on the roof to do work.

Are the solar cells and powerwall shielded by any kind of solar storm? I couldnt find any detailed information confirming or denying it. I would not like for any of us to be in a situation where the 1st solar outtage is our most damaging, and thats what causes any producer of electronics to adopt labeling and marketing for it.

Solar storms don't reach the earth, one of the jobs of our atmosphere and magnetosphere is to protect us from it. So there's no point in making protections against it for solar panels on the planet.

Not to mention that coronal mass ejections (CME) happen so often that you'd expect to have already heard of such power outages if one were possible.

In CA, it is illegal for HOA to block solar installations

Earlier quoted context omitted.

Where are you seeing $3000? When I set it to 1 Powerwall it tells me: One 14 kWh Powerwall battery $5,500 Installation and supporting hardware starts at $1,000 Total estimate $6,500 Requires $500 deposit for each Powerwall

I don't see $3000 - that's my point. But for $3000 I'd buy one.

The powerwall 1 (are they still selling them?) is at exactly that price point, albeit with half the energy storage capacity.
