If I were entering data on that spreadsheet, I would need a separate column for an intangible cost: the noise and smell that accompany generator use.

Well bless your heart StirCrazy...
325 watts @ 12 volts = 27 amps. (The worksheet calculates 300 watts = 25 amps)
My Honda generator produces 133 amps (this has not changed).
Yes the table may be a decade old, but that does not change the accuracy of the breakeven results...5.4 years if the generator is used 1954 days.
How many years do you calculate as your breakeven number?

Here is a link to Solar vs Honda financial breakeven analysis that will help determine which source of power is cost effective. This analysis indicates for the Honda 2000, it will take about 5.5 year breakeven, or around 1954 days of usage.

Of course the breakeven analysis for carbon emissions is a different story all together. At what point does the accumulated emissions from the generator's manufacture and operation match that of the solar panel emissions? If we take a page from the BEV's breakeven analysis, then it probably is several years away for heavy RV users and probably never for the occasional weekender.

Where are you buying fuel at those prices today?
You have not factored in maintenance. My Yamaha wants oil every 50 hours. If I relied on it totally and ran 24/7 that's every two days, two hours.
