Net Metering Debate Rages On Despite Calls For Calm

I have a 10.24 KW DC PV system that cost me a net $0.91 per watt for a 20 year prepaid lease. I won't bother you with more details then are necessary, but seeing there are obviously a number of savvy energy buffs on this thread, can anyone help me determine what a realistic ROI on the system is? My previous 12 month bill averaged $200/month.

I sized the system to provide about 85% of my load, but find I am producing over 100%. Since I understand the panels alone cost around $1.15 a watt to produce, it seems like I got a good deal. I realize this is somewhat off the subject, but I would really appreciate some help.

Thanks, John

Solar Shakeout Continues: Stirling Energy Systems Files for Chapter 7 Bankruptcy

Very Stimulating observations. I have wondered about the viability of using a 3 to 6 KW stirling coupled to a parabolic trough through a heat pipe. The lower profile could be more acceptable for residential use. Any thoughts?
