Some years ago this chart from the DOE convinced me that solar power was in trouble; that 4-5$/watt was about as good as it gets. Bad news, given that coal is substantially cheaper than than. It was beyond my wit to know what the source of this problem is. It might be market forces – that the floor looks like it was hit just about the time the pulse of money generated by the 70’s oil crises is thought provoking. It might be a technology limit of some kind, something in the physics say.
In any case it appears there is good news. Because these folks are claiming they will hit a dollar a watt soon. “we believe will make us the first solar manufacturer capable of profitably selling solar panels at as little as $.99/Watt.” That’s the future tense, and it doesn’t include the rest of the capital equipment involved in the installation. Good news none the less.
It’s weird that they are shipping them to East Germany; you’d think they would prefer someplace sunny.
