> I'd expect most tech people will value the distributed nature of solar over equivilents, that by design require centralisation and commerical/state ownership and control.

I do, but I do not find value in rich folks who can afford solar wanting their cake and eating it too.

If you get a solar setup, get batteries. Then disconnect from the grid entirely. You should not be able to use the grid as a free backup energy source for the last 5% of the time you'll need it. Those last digits of reliability are the expensive hard problem to solve. That, or be charged appropriately for adding your potential usage to the capacity market. I understand that this is not legal in many places, and that folks disconnecting from the grid also cause the grid to collapse at some point as well. But at least there would be less of an individual perverse incentive involved.

Home solar folks seem to love their free battery though. Or even worse - getting paid to dump power to the grid when it's value is the smallest. Net metering is not the way to go - home solar should be being paid something around instantaneous wholesale pricing at best, plus fees to manage the more complex management of the grid they cause via being thousands of kilowatt-scale install vs. a single 50MW solar farm.

So far in the US at least, many solar programs have simply been a handout to relatively rich folks subsidized by poorer grid consumers. It's really put a sour taste on something that should be for the greater good. I don't mind that those subsidies were used to jump-start the industry, but that time has long since passed.

tldr; if your total system cost to be fully off-grid and never have to worry about a power outage is not substantially more expensive than being grid-connected, you are likely being highly subsidized by other electricity consumers.

While many rich are benefiting, they are still driving demand, that is funding continuous improvements that funding further efficiencies innovation and driving down the cost per kWh. In a very really way this makes solar cheaper and cheaper, the benefits of this one, unlike the debunked economic namesake do infact trickle down.
