Is that really maximum? Cause the other site I went to had better watts / m^2 based on 5 hours of sunlight a day. Obviously, the maximum would be with direct sunlight, and that doesn't happen for very long.
Cost per panel - $611 (US) each (must buy in bulk).
Cost per watt - $3.79
So to get your 1,600 watts mentioned earlier you'd need to fork out $6,064 up front for the panels alone.
I found a place that was cheaper, but that's not a big issue.[/quote]
Now a nice consumer spends what 10 cents per kWh? So for your panels to pay for themselves you'd need to wait 7 years ... if you ran everything 24/7. THIS IS JUST FOR THE BLOODY PANELS.[/quote]
I'm pretty sure the watt rating was based on 5 hours of sunlight a day. That seems to be the industry standard for watt ratings.
Anyway, I pay less per Kwh and it would take me only 8 years to pay off the materials. Less than 3 for the labour.
In other words this is from a COMMERICIAL ENTITY trying to sell a product, so their bias is TOWARDS SOLAR.
Now what's the out the door price for a solar kWh? Niels Wolter (of the the Wisconsin Solar Use Network, a pro-solar group) estimates it at 18 cents a kilowatt hour after pro-rating the system for
40 YEARS.

Now this would strike the SANE person as a bad economic invesment. It's a MYTH that solar systems break even in the long run.
I don't know why you are getting the numbers you are, but power here costs less than 6 cents per watt and I'd pay off even $10,000 in less time than that. Less than 12 years, and that's assume energy costs don't increase in those 12 years.
The only reason solar is remotely viable is because governments like to burn money (fine the government wants to be green ... you get vastly more for your buck just getting a more efficient refrigurator than going solar). I highly doubt your solar powered home is remotely economical without subsidy and I highly doubt it can be powered without first be extremely efficient (which means you have even higher up front costs).
But isn't it being energy effiecient a smart thing do regardless of your power source?
Now ALL of that is conditional on using the utility company as a giant battery. You dump your excess in and pull your shortfall out. If a substantial number of people did that, then the battery no longer works in the event of bad solar conditions.
I don't think Industry can effectively used Solar, neither can apartments. So other sources are needed. These can always be used as giant batteries.
Given the pollution generated with silicon etching I much prefer nuclear. Go CANDU.
I'm all for Candu, it helps the Canadian economy. But Candu has the nasty side effect of creating weapons grade plutonium.
