Payback time in Scotland is 6-ish years. Same seems to be true in Massachusetts. Solar Panels have a lifespan of around 25 years. Inverters may need to be replaced sooner than that, but still last at least a decade.

So it pays for itself 3-4 times over.

There is no way that is true unless those solar panels are very subsidized. The energy needed to make a PV is 2x what that panel would harvest over its entire lifetime in Scotland for example. Scotland is a terrible place for PV. The numbers you give are probably accurate for central Mexico though. Also, the mean lifetime of a PV panel is 20 years.

We spend billions every year in gas subsidies. We spend billions every year in food subsidies. For energy independence and the carbon reduction alone, this is a worthwhile investment even if the upfront costs are substantial.
