Even Thin Solar Can't Weather Silicon Glut - Barron's [View article]
I run a solar electric program in a medium sized state. Last year we cofunded about 870 kW of installed systems. This month we got in about 200 kW of applications. This is before the stimulus money hits. This year may surprise the forecasters.

Let us assume $5/watt, annual generation of 1.4 kilowatt hours (kWhs)/watt of PV and see what price of power would be required for a PV system to pay for itself it two years.
First cost: $5/watt Cost after incentive: $2/watt Generation per year: 1.4 kWh Generation over two years: 2.8 kWh
Cost of power required to payback over two years: $2/2.8 kWh = 71 cents a kWh
Electric prices are not that high, not even in Hawaii. I currently pay about 13 cents per kWh here in the Midwest.
You can be sure that power prices are far lower in China.

Hey Aquaculture - I believe you mean ground sourced heat pumps not geothermal. Speaking as a geologist, geothermal is hot water gysers etc. Ground sourced heat pumps use the stable temperature of the earth as a heat source (winter) or sink (summer) for a heat pump.
