It's not hard to do the calculations yourself:

You calculations essentially tell someone only whether solar is cheaper for
them vs. buying grid power. While this is very useful, it wasn't what the
O.P. was after -- whether or not solar panels were a neat energy sink.
Indeed, given how regulated the energy business is with taxes and subsidies
for various technologies, there's pretty much zero correlation between the
two.

BTW, for the cost of getting energy off the grid, you also need to include any
losses due to grid power outages. While in many places outrages are rare
enough this is essentially $0, people out in the country a bit often have
frequent and long enough outages that losing, e.g., some of your frozen food
isn't uncommon -- we've probably lose ~$100/year this way.

How will a solar system do when it's cloudy for a week or two? Or when
the panels are covered with snow?
