“MCLEAN, Va., Jan. 14 (UPI) — Oversupply and low demand have made solar panels cheaper for U.S. homeowners.

Prices for rooftop solar systems, including installation, have fallen by 8 percent to 10 percent since October and are expected to drop an additional 15 percent to 20 percent in 2009.”

via Oversupply pushes solar panel prices down – UPI.com.

Strange math in this article. 15 – 20% panel price drop and the whole system goes down over 50%. Must be incorrect or missing logic somewhere, maybe the expected government subsidies are huge:

“In California a typical 4 kilowatt, $32,000 solar energy system cost a homeowner about $23,000 last year after state and federal incentives. This year, if the price predictions come true, the price for the same system would be between $10,000 and $12,000.“
