So as us. Please ask how much Uncle Sam is subsidze the PV. The main cost difference is our land cost and regulation cost not PV cost. With Fed and state sub we can also get a PV for free. How about Chinese? I heard they pay about $1/W for PV and $0.50 for equip after subsidze their Chinese PV. There is no sub for US made PV which is costed about 2X more than local PV in
China when I try to export to China.
Just to be clear, I assume you are talking about the period to pay back for the energy used in manufacturing.
A useful rule of thumb: Final 'retail' cost is about 4 times the manufacturers cost to produce.
So, your four year worst case is not inconsistent with the 48 year payback given that the full cost includes a whole lot of other stuff.
Umm, my figures above were for a 2.5KW system. A big chunk of the subsidies in Oregon phase out just above that wattage.
Right-sizing for me would be about 4KW. But the extra 1500 Watts would cost about 4 times more.
This sound more like a failure of the business model, not the technology. They should have targeted niche market first and expand slowly to give their product time to mature and gain market recognition. Hope this will not scare away the wannabes to continue innovate in the solar field.
