Zerolot so what is your expected annual savings by doing the lease?
I don't know the annual savings yet, I'm just going month to month. So here's the math, all based on approximations:
Neighbors currently at $50/ month uses 371 kW, they use no AC
Neighbors who use a little AC at $100/month uses 571 kW.
Neighbors who use 2-4 hours of AC a day is around $150/month uses 737 kW. This is assuming they don't have my electrical issues as previously stated.
I'm basing off other residents I've spoken with in my hood because we have similar houses and we are all 3 bedrooms from same builder.
Anyone using less than 600 kW will not benefit from solar because it will take them forever to recoup if they purchase. If they lease the leasing companies only install at a minimum output value.
The break even point is around 700 kW per month for summer.
With a Solar City rates of 15 cents per kW, 0.15 x 700 = $105/month.
0.15 x 737 = $110.55
Savings would be $150 - $110 = $40/month.
This is all in theory and based on the June 2014 rate. July 2014 the difference would be $45/month.
Is it significant, no. It's not worth it if I purchase to save $45/month.

Now assume if I cool my house to a nice 76 degrees during the summer, I may be at 1000 kW, which Edison charges $250 in June 2014, $280 in July 2014.
Solar City can only give me a 761 kW production at $114, the remaining 239 kW I purchase at 0.15 from Edison at $36.
$114 + $36 = $150 new electric bill with Solar City + Edison
Compare that to $280 if I didn't have solar ... Well that would be a $130 savings in the summer months.
Now I'm basing off Solar City rates at 0.15. If I went with Sullivan and upfronted a car payment, I would save more.
Again to speak in annual savings I don't know. Over the course of 20 years the sale people said I will save $40k. Sounds nice not sure if that's all true.
