[Bldg-sim] Real-time pv yield as a surrogate for irradiance

You can use anything you want as a surrogate, as long as you have some way
of proving it works. In this case, if you could somehow get real time PV
data for a set of sites that also had actual insolation and then looked at
your results, I think you could derive a typical relationship that wouldn't
lead you too far astray. The problem will come when there are passing
clouds and the PV system is "hunting" all the time trying to catch up with
the changing insolation. I bet you could find those and apply a bias
correction that could then be used in multiple sites with real time PV
