While it's true that solar panels have dropped they are still expensive and in many states there are few to no incentives offered to help defray the costs. The permitting issues he raises are also valid. If it were easier and there were incentives I'd be happy to spend a pile but as it stands now lack of incentives means few installs in my state and thus even fewer installers.
Also, this guy is an idiot. The fact is that panels on every single home would NOT prevent power failures unless they all also had battery banks which drive costs through the roof. Grid-tie systems are what most people install, surprise grid-tie relies on those very same copper wires this guy is crying about being fragile. I'd REALLY like to know what he means by "wired so they provide power when the grid fails" because without batteries this simply isn't feasible unless he thinks everyone should seriously upsize whatever solar install they might have planned. If he thinks that everyone should backfeed the power system then he also doesn't understand how dangerous this is. When a generator is hooked to the system in a power failure homes are disconnected from the grid in order to avoid killing power workers and from frying the generator as it tries to power the whole block. Trying to do this with panels alone isn't likely to have a better result. Grid-tie homes lose power just like everyone else, few have arrays and inverters big enough to power the entire home - their meters spin backwards at low loads only. Certainly batteries are an option but they require maintenance, have replacement costs, weigh a ton - sometimes literally, and can triple the cost of an install which is already damned high. If you're in the boonies and the power company wants $30K to string you a wire they make sense otherwise no you stick to relying on a grid connection. Power a few circuits for lights, say via LED, or other small things sure but you're not going to be powering a whole home on just panels without some storage and more complexity. Most systems aren't sized big enough to power everything except at peak power output which is a small portion of the day. Off-grid systems marshall their inputs into batteries to allow for occasional peak usage, he doesn't seem to understand that.
I don't think this guy has really thought through what he wants. He sees solar and thinks it's magic pixie dust, it's not. When the infrastructure breaks this stuff doesn't magically solve the problem. I'm all for more solar and putting it on everyone's roofs is a great idea but it's not going to solve the basic infrastructure fragility issue and might actually make it worse.
