Costs of solar power ($/wp) – as of Oct 2006
solarbuzz.com
As of October 2006, there are currently 176 solar module prices below US $4.75/Wp (€3.71/Wp) or 9.9% of the total sample. This compares with 178 prices below $4.75 per Watt in September.
The lowest retail price for a multi-crystalline solar module is $4.31/Wp (€3.36/Wp). This price is exhibited by a US dealer. The lowest retail price for a monocrystalline module is $4.42/Wp (€3.45Wp), from a US based dealer.
The lowest thin film module price is at $4.00/Wp (€3.12/Wp) per Watt from a German dealer. As a general rule, it is typical to expect thin film modules to be at a price discount to crystalline (for like module powers). The price differentials in this survey are presently consistent with that assertion, since the thin film module in question is 41 Wp, while the crystalline modules are high power 140-160 Wp models.
