Our utility(CL&P) is required to net meter grid tied solar systems. Once a year they "settle up". If they owe you for kwh's - they pay you the generation rate as of the day they settle in the form of a check.
I have been very happy with the whole process(except for a 15.00 a month delivery fee on electricity - so I can never really have "no" power bill). The net metering makes it real easy - without the net metering - there would be NO way to justify the expense of the panels. During the day we "bank" a LOT of kwh's - without the metering - we would lose those kwh's - or have to install a VERY expensive battery bank(it was around 30,000.00 dollars).
