NextEra Energy Chief Executive Lewis Hay told me last week over breakfast that he had higher hopes for solar photovoltaic (PV) power than for solar thermal power because the prices of solar PV panels were falling so extraordinarily fast.

But most days, I make enough roof top PV solar power at home to avoid buying coal-based utility power.

Plus, my PV-sourced solar power has no inflation for the next twenty five years, and no price volatility.

PK), Phoenix Solar, Neo Solar Power, PV Crystalox Solar (Other OTC: PVCRF.
This might make sense for large scale solar farms, since the integration of PV would allow the overall price of power to be lower than CSP alone, while CSP would be able to compensate for the rapid output changes from PV that occur whenever a cloud passes over, as well as producing power at night, or shifting it ot peak afternoon periods.
Suntech Power commercially manufactures PV cells utilizing Pluto technology.
After Hurricane Andrew in 1992, PV systems were brought in to provide power to shelters and streetlights.

The basic idea, as is done here, of using sunlight through solar PV to electrolyse water, store the hydrogen then, when the power is required, reverse the process.
My PV array allows me to avoid buying any of the expensive afternoon power, so the payback time is reduced in proportion to the pricing ratio in the power rates.

Instead of a decade or more to break even, a solar PV investment pays off in just a few years when the electric power is used to avoid buying expensive gasoline.

Suntech Power is currently pursuing thin film technology, a low cost PV technology that involves depositing several thin layers of silicon or more complex materials on a substrate such as glass to make a PV cell.
Down 40% in the past year, PV modules now account for only about a third of the cost of a power plant.
While the low water use and cost of PV will appeal in the desert kingdom, the fact that solar will be displacing power generated from oil means that even CSP based power will produce cost reductions.
Anne Lauvergeon, chief executive of the French nuclear giant Areva, hinted last week during a meeting in Forbes offices that Areva is developing a hybrid solar power plant concept that combines a solar thermal system with solar photovoltaic (PV) panels.
