The second, and much improved, version of California’s experience with PV prices, Tracking the Sun II, has been released.
It is a huge step forward from the previous report, which seemed to treat CA as an island and ignored the much greater experience of the non-CA-dreaming world outside. This year there are special sections comparing CA with Europe. We are blessed!
However, the report is still out of date, since it ends in 2008 (with an unrevealing peek at 2009). As we know, prices for silicon modules have dropped like a stone, and very large quantities can be bought under $1.5/W.
Now what we can do from the CA report is actually estimate what we should be paying going forward without getting ripped off. The reason this is important is that most people will read the CA report without the knowledge of the staggering plunge in module prices and think we are still stuck at $8/W for residential systems (and similarly high prices for the commercial and big ground-mounted systems).
