In the US, wind power is getting bigger and better, report says

1. Electrically, solar does feed your house first. It interconnects before the meter and into your main electric panel. The reason it doesn't work during an outage is because of regulations requiring solar to turn off during power outages so that electricians fixing downed lines don't have surprise power from random houses after they turn off the grid power.

2. If you want solar to work during an electric outage you need to install a battery backup that can feed it AC power and disconnect it from the grid during a grid failure. However, you need a pretty big battery to power a full house for a long time so it's generally cheaper and easier to have a gas generator backup if you are worried about this. Batteries are really just good for energy arbitrage purposes these days.

3. There are inverters that have an outlet that works during grid outages, even without batteries (https://www.sma-sunny.com/us/how-to-explain-secure-power-sup...). They generally cost the same

I wonder how many electric F-150s will get sold to people on the basis of using them as a whole-house battery.

I fully agree on your point of the lack of logic to grid-based solar. No doubt large scale facilities can be placed in better areas, be cheaper per watt, have higher uptime, are able to afford the more exotic power storage (dams for one).

Now, if it were me, I'd start with new construction designed around low power usage. LED lighting, efficient computers, chest freezer turned into a refrigerator, no electric heat or dryers or transfer fans for gas heaters. The sticking point would tend to be A/C but I think that can be mitigated via small house size, insulation, and use of efficient split systems. The smaller the electricity use the more tractable the problem.

To be clear, even at $90k that's cheaper than buying a pile of power walls or similar. So it seems like it's a power wall array plus a free truck :).

I expect we get away with it right now due to rarity.

I don't see the solar site management thing happening by the way. A lot of time and effort goes into land siting and selection. It won't be that easy to just pack it up and move.

I can see this happening more in the future when you kind of run out of space and have increased demand for power. First thing you'll probably do is upgrade the turbines to be bigger/more efficient. Then if you've maxed that out you can start adding solar panels underneath the turbines.

At the end of the day it's about lowering your costs to generate the power you need.

I think it might create a long stall where solar doesn't really expand that much in consumer markets.

I don't think that I'd want someone that isn't a licensed roofer or electrician doing the installation work anyway.
