Oh how I wait for the days of using solar to heat my home during blizzard night... People posting these headlines make it seem like utopia.

I don’t know where you live, but the Californian power grid is part of the Western Interconnection that goes from the Mexican-American border to half way through Canada[0]. Are blizzards in the USA ever that big?

As for “at night”, it is possible to get batteries of household scale. Plus insulation is getting better and cheaper, so the power required to maintain any given temperature isn’t as high as it used to be.

At times of the year when there are blizzards, I seriously doubt the rest of solar installations in the US are going to be running anywhere near capacity.

First: So? PV is so cheap overcapacity isn’t unreasonable.

Second: My first visit to the USA, I saw people surfing in Asilomar on Christmas Day/Boxing Day and it remained warm and sunny throughout my stay in California, yet a few days into that trip New York was suffering a blizzard that Trump was trying to argue disproved global warming: https://en.wikipedia.org/wiki/Early_2014_North_American_cold...

You're assuming they have an infinite lifespan. They don't.

No I’m not. If I thought they had infinite lifespan I would be claiming solar was effectively free rather than, as I am actually claiming, just cheap.

Sorry - I'm talking about California - not everywhere. We in large part do not have blizzards.
