re: Does the left really believe we can power the entire country on solar and wind?

what kinda isht panels are you talking about? Quality panels haven’t improved anywhere near that much
Then how much have they moved. I don’t do this all day, everyday for one of the largest solar companies in the US or anything.

A 5kw system at 100% efficiency ( no other loads ) is 27/5. Good luck doing that under 5 hours.
Thank you for proving that you’re estimation was wrong. Even a small system, which is significantly smaller than the 9kW average of current installations is on the low end of your estimation and a more average sized system performs obviously better.
And to reiterate, solar isn’t for everyone or every household, but disregarding distributed generation and utilizing all options for energy is a ridiculous argument.

Last thing I saw was Trina with an IBC cell a hair over 25%. No where near the 40% improvement you're talking about. I guess that could make sense if you compared the cheapest crap-azz utility grade panels from 10 years ago to a modern IBC cell. But that's not exactly a like-to-like comparison.
quote:yeah. I response to the assertion "that even a small array of panels can fully charge a car." A 4'x5' panel does about 350w in perfect conditions. I'll leave the math to you to decide if charging a 27kwH in a reasonable (1-2 hours) is a small array or not.
