As an Australian, the lack of anxiety and guilt you get when you're using 10-12 hours of air conditioning in the middle of summer and not paying for a cent of it because your solar panels are covering is worth more than anything
Why shouldn't that be true practically every consumer home in the world?
Yes, grid scale deployments are cheaper, but I'm generally guessing a lot of the grid scale solar deployments do not price in the grid infrastructure adaptation costs, and I'm not even talking about grid storage.
Consumer rooftop solar is fundamentally democratic: it reduces reliance on centralized institutions for power delivery, Make society a lot more resilient in bad weather and other emergency situations, insulates everyday people from wild variations and petroleum and other consumable energy availability.
Combined with plug-in hybrid electric vehicles, it would enable electrification of 80 and 90% of daily driving without grid infrastructure costs.
You should still feel some guilt for the heat pollution your air conditioning causes for those outside your house, esp. in an urban area.
Yeah totally, nice to be able to put the AC/heater on "for free". I even got a negative power bill once!
In my specific case, I barely use much power so home solar covers basically all of the usage, my bill is dominated by the daily charge, so the usage component is practically irrelevant to me.
