In southern California the average residential customer with an air conditioner can have an electric bill from $200 to $600 per month. The typical home will require a 2 to 6 kWh system to get relief from these increasing bills. The following table provides simple estimates.

*Summary:

The electric company rebate is calculated on the actual production of solar electricity your system produces. This is a function of several factors, such as the direction the panels are facing, the tilt of the panels and the shading. The type of panels installed also influences the rebate. The rebate is tax free for homeowners. The 30% Federal Tax Credit (FTC) is taken on the net value: Gross Cost less Rebate. The FTC can be rolled forward for 20 years.

* These results are approximate only. Your individual results will depend on the position of your roof, the tilt of the roof, shading and your current electric demand and use.
