Why the low demand for solar panels are so expensive?,?
In 1960, the cost of production of the IC (Integrated Circuits) was $ 1000/IC, now the cost is cents or less, because high demand and improved manufacturing process. At that time the demand was only for military ICs and software space. Is there anyone interested in not stimulate demand and / or improvement of solar panel production (oil, auto companies) or just a technology issue?
In 1960, $ 1000 or even purchased 1 watt of solar cells, but today, 1 watt (a fraction of a cell) costs about $ 4. So prices have fallen. The difference between solar panels and the IC are that solar panels have a large quantity of raw materials, and CI are very little. The cost of material (without transformation) of an IC may be a few cents, but a solar panel has a significant amount of silicon, to say nothing of a framework aluminum, iron and sealed under glass. So a solar panel can not be 25 cents more than a double glazed window can be 25 cents dollar. That said, I think the panel prices will drop 20-25 percent in 2009.
