So prices have come down. The difference between solar panels and IC's are that solar panels have a lot of raw material, and IC's have very little. The material cost (not counting processing) of an IC may be just a few cents, but a solar panel has a significant amount of silicon, not to mention an aluminum frame, and hermetically sealed low-iron glass. So a solar panel can never be 25 cents, any more than a double-pane glass window can be 25 cents. That said, I think panel prices will drop some 20-25 percent in 2009.<br><b>References : </b><br> In 1960, $1000 may not even have bought 1 watt of solar cells, but today, 1 watt (a fraction of a cell) costs about $4.

The difference between solar panels and IC’s are that solar panels have a lot of raw material, and IC’s have very small. The material cost (not counting processing) of an IC may be just a few cents, but a solar panel has a significant amount of silicon, not to mention an aluminum frame, and hermetically sealed low-iron glass. So a solar panel can never be 25 cents, any more than a double-pane glass window can be 25 cents.

That said, I reckon panel prices will drop some 20-25 percent in 2009.
