Grid-tied solar is fragile. If the grid is not nearly-perfect, it won't generate. It will not help society as a whole.

If you personally have battery backup, that helps you personally and you should pay for it, just like you might pay extra to turn up the heat while I keep it lower to save money.

In Canada (or the US) the grid is reliable and so you can ignore when it isn't working. This doesn't apply everywhere in the world

Which is why the money should go toward getting 10x utility solar than roof solar.

Grid-scale solar installations can be much more decentralized than nuclear or natural gas power plants.

Decentralizing through subsidies at the homeowner level is maybe not the best use of money.

> Decentralizing through subsidies

Consider the lower production cost of renewable electricity: in the long run, it offsets the investment. Bonus: no risk of accidents, no hazardous waste, no dependence on a fuel source, no weapons proliferation...

I didn't say subsidize nuclear. I said subsidize grid-scale solar before rooftop solar.

Indeed, sorry.

Decentralizing solar power reduces electricity transmission costs and improves reliability. This doesn't offset the additional cost, but it's not negligible.

If the grid gets heavily overloaded, the frequency and voltage drop. And home-based grid-tie solar will shut itself off when it's most needed. This is fragile and DEcreases reliability.

Storage, such as batteries coupled with V2G and also green-hydrogen fed turbo-alternators, can alleviate this.
