Thank you, this is very helpful.

On microinverters, though: I don't know about other microinverter systems, but I've been running a 10 kW array with 34 Enphase microinverters for about a year now, and we've had zero problems with our wifi reception - and it's going a large distance across the house. (There is a different issue: The microinverters embed panel performance data in the AC line, and an Envoy unit inside the house, which is connected to the router, extracts it and sends it to a server, so your web and smartphone app can work, give per-panel data, etc. *That* AC line encoding doesn't work well when we have lots of stuff turned on, using power. But it can buffer up the data for months, if necessary, and we've never had it go more than a day without being able to extract and send the data.)

Almost every article I read says "efficiency" (% of photon energy converted to electricity) is the problem with solar panels, and there is all this focus on higher-efficiency panels. But let's get it straight: It won't be rising efficiency (watts/m^2) that make solar panels really take off; it's not like limited roofspace is the bottleneck that we're all fighting here. It's cost: dollars per watt. As cost drops, solar panels should further proliferate.

Where else do you propose finding people with the relevant experience to these government positions? Fairyland?
