Some key insights from the article:
Basically, what they did was to look at how much batteries would be needed in a given area to provide constant power supply at least 97% of the time, and the calculate the costs of that solar+battery setup compared to coal and nuclear.
They modelled it for other places too.
Yeah I saw that… Though I’m 3 years into solar and my measurements aren’t so positive. I am definitely not covering 62% of our needs yearly. The 4 less sunny months are killers when you need heating.
I saw a video where a guy was claiming vertical solar panels can effectively generate more power more often. They can catch a little something when the sun is low in winter , or on the shoulder hours of sun-up/down, where traditional solar can’t, and they don’t get snow buildup
it's a trade-off. the average generation curve depends on the inclination; each has its pros and cons
62 percent could be 7 months all the time and 5 never right? So if those 4 months only get you 20% but the others give you ninety something. When I see that 62 I see it as over half the year it will work out good.
Yeah but that would not account for the electricity need: in winter we need between 1000/1300 kWh mainly for heating / domestic hot water. Other months under 250 even if we use air conditioning. So if you cover the 7 nice months you still get absolutely wrecked by the dreaded 4 in the winter cost wise…
They just assumed a constant draw I think.
