"I have seen no evidence of this. On the contrary, costs of photovoltaic cells seem to be increasing."

You are correct. The cost has roughly doubled since 1999. I bought the parts for a 1000 watt system for $6500 in 99, and was looking into doubling it last summer, but just the additional panels would have cost $14,000.

I just bought a small panel intended to trickle charge my car battery that cost $15 a watt. This cost is not encouraging.
