Those numbers are WAY off!
The largest system in Germany couldn't have cost 1/8 of that number and no one builds a commercial system that doesn't have a payback period of less than 15 years, most are 10 years or less.
PV Module cost is very rapidly approaching $1/watt and the BOS is the big problem now. Many of the small companies are folding, but the biggest are just getting bigger and some are posting record gains and a few of the silicon suppliers are sold out till 2013-2015.
The industry is leaning more towards utility scale plants instead of resi scale. The GW scale arrays in planning and construction right now in California dwarf the largest European arrays and are being installed at substantially lower $/W numbers.
There's a LOT of PV hype (good and bad) and very little of it is really true, at least in the context in which it is hyped.
It won't be, but a few years before subsidies are no longer needed, but without them the industry would have never got to where it is today.
