Well now you see why there is no escilated costs.
Here's the break down.
Sungevity was to offer 2.8KWH Hyundai panels with a 2.5KWH Kaco inverter (which I think is one of the cheapest and crappiest inverters to own), to equal a AC CEC of 2.28 KWH. Sungevity would lease this system at $80 per month no escalation costs. As you said, cost for that system over 20 years is $19,200. This system is crap as sungevity claims it would only offset the utility bill 60% annually. I looked into the cost of piecing together the same exact system if I was to out right purchase it. Window shopping at amazon and some warehouse outlets the cost without the tax credit was $18,980 with a contractor to put together the system, that's without the tax credit. Tax credit would be $5694. System after tax credit would cost $13,286. So over the course of 20 years sungevity makes $5914.00 in intrest, plus the $5694 tax credit, minus the $500 cash back incentive upon energizing.
Sunpower lease is $110 per month but offsets the utility bills on average by 85% annually. Uses better quality inverter and would install 3.65KWH of sunpower panels, to max out the spr-3000 inverter ( which I've been told is a sunny boy 3000US model). I can't make the cost comparison on sunpower products line as the actual cost are hush, hush. However I do know the invereter costs double that of the Kaco. Sunpower is probably making about the same on investment the sungevity is making, however the bottom line is the utility bill owning the sunpower system will remain lower longer, and overall looks like the better investment.
Solar city seemed to sway more in the direction of using micro inverter, and again like sungevity was only really looking to offset the annual cost of the utility bill by 60%.
