I've been watching solar panel pricing for the past few months. The price drops have been dramatic. The 30% federal tax credit and other incentives are starting making a PV system a viable investment.

Best panel pricing I'm seeing (UL, CE listed panel) is around $2.60/watt. I'm seeing grid tied systems (ready to install) for around $4/watt (10kw system).

Tennessee's only incentive is through Tennessee Valley Authority's Green Switch Program where green power is purchased for $0.12/kwh over the retail rate, which is currently around $0.09/kwh. Given a 30% federal tax credit and a higher rate for solar power, I am seeing return on investment of ~5%. That isn't bad.

Anyone else working the numbers? I thinking about making the jump when panel pricing reaches $2/watt. If TN had aggressive cash rebates I'd have already made the jump.
