One resource which might be helpful in arguing your case is Minnesota's "Value of Solar" methodology document.
The quick summary is that last year the state passed a law allowing utilities to substitute a Value of Solar (VoS) tariff for net metering; under this tariff the customer would buy all power at retail and sell all produced power at VoS. But the state also specified that the VoS rate had to include all the benefits to the utility of the generated PV, as well as avoided pollution costs.
So the state went through a months-long process to figure out how to calculate VoS, and everyone (utilities, customers, PV installers, etc.) got to have their say as to what the value of solar really is.
And at the end, they produced a detailed document with actual calculations. Here it is.
The exact numbers will differ quite a bit from place to place, but this gives you a concrete way to show that PV really does have value, and a way to calculate it.
By the way, after lobbying hard to get VoS passed into law last year, none of the utilities have actually filed a VoS tariff yet. Some people think that's because, when the utilities are forced to actually calculate the VoS rate including all the factors they are required to include, it will come out to be higher than retail. Here's an example calculation which comes out to about $0.03/kWh higher than our current retail electric rates in MN. That's partly because VoS includes avoided environmental costs, which the utility does not currently have to pay but which have to be borne by the community at large. In other words, power companies are being subsidized by not having to pay the full cost of the pollution they create.
