CA Solar Tax Credit - if you take the Solar Rebate you can not take the Tax Credit. Also, the tax credit is limited to about 1/3 of the rebate. So, you always take only the rebate.
This is flat out wrong. You can take both the rebate and the tax credit. The subtlety is the tax credit is taken on the *NET* amount after the rebate. In most cases this is simplified because the installer takes the rebate so homeowner and purchaser takes the tax credit on what they paid.

Both the rebate and credit can only be taken once per property location - so if you add to a claimed system or build a new one on the same property - you get nothing!
Not entirely true, it is possible to apply for rebate for the expansion of a system. I just looked into this because I was considering expanding my system. The tax credit is indeed limited to once per property.

I would think that the other state's rebates/credits have same limits.
For a small system with 24 KC125 panels with one ST2500 inverter that you pay someone to install = 10,680 + 1,250 + 5,000 = $16,930
Rebate = 24x125x.94x3.75= $10,570 but limites to 50% = $8,465.
Cost = 16,930 - 8,465 = $8,465
At $0.12/kw: System must generate 70,541 kw/hr to pay off cost
How long will it take a fixed 3000 panel watt system to generate 70,541 kw/hr?
I bet a long time - Richard
In PG&E land you can't $0.12/kWh unless you are on lifeline service. A consumer with significant usage ends up paying around $0.24/kWh for marginal power because of the surcharges.
With Time of Use metering it is possible to get almost $0.32/kWh for energy sold during peak while off peak power costs around $0.09/kWh.
So if your consumption is high enough you are likely to break even on a cash flow basis on day one (For example assuming you finance the system on 30 year home secured loan).
If your consumption is not very high but you can sell during peak (or buy very little), you can achieve the same thing using TOU metering. TOU can also benefit high energy consumers if you can shift their load.
