Seriously, the man is a genious, but batteries for homes is not that good, unless it is possible for utility to control them as well. At the very least, Tesla should make available server software that utility can interact with home batteries when owner allows. In seasonal weather with high demands and when solar can be blocked via clouds or length of day, it is best to allow utility to control when to charge them , or buy from them.

2) Cloud... And the difference [between sunny-day production and cloudy-day production] is less than you'd think - it's about 90% of summer rather than the 25% or similar you might think.

That has not been my experience. For example, here is my system's output on April 25th (which was a cloudy day), and here is the output on April 26th (which was a sunny day). The cloudy-day output was about 10% of the the sunny-day output.

What would make solar energy viable would be panels that didn't cost $30,000 to buy and install. [...] I just don't happen to have $30K laying around.

This game changer has already occurred in many places. There are many locations where you can get a home solar array installed without paying any money for it, because the installing company is willing to pay for the equipment and installation in return for selling you the generated power. This is appealing to consumers because they get a significant reduction in their monthly power bill, they don't have to pay anything, and they don't have to take on the risk of not getting the expected return on their investment.

The fact that solar companies are willing to take the financial risk on the customer's behalf indicates that the risk/reward ratio of home solar installations is already low enough to be economically viable, and it will only improve over time.

If that 10 years is maintenance free as in I don't have to do anything to it He will win big.
The biggest problem with off grid solar+wind installs is that caring for the battery bank is outside of the abilities of 80% of the population. If musk can make an off grid solar/wind install a zero effort/ zero care system where the drooling masses don't have to do anything.....

That will get the adoption rates way up, if the payback is within 5 years.

"Corporations don't hold guns to their customer's heads."

AS in a physical gun? no not yet. But they hold financial guns to peoples' heads all the time. and many times try to do financial assassinations.

Why kill a person when you can make them suffer for the rest of their lives financially.
