So the delta between .16 and .22 (even in the short term) is being paid for by whom? The rest of the rate payers I would guess. The entire solar power/green energy deal is a scam.

Your capacity factor will be in the 10%-15% range, meaning your 1.2 MW (1200 kW) will produce on average about 150 kW (day/night, sunny/cloudy).

1200 kW X 12.5% X 8760 hrs/yr X $0.22/kWh = $290,000 per year.

If that justifies your investment, go for it. (You should be able to get a better estimate for the capacity factor.)
