I'm looking into a DIY install, and it's looking like the microinverters are going to basically be just as expensive as the panels themselves. A quick Google seems to imply this is similar for utility-scale installs: the BoS costs are less than, but still comparable to the costs of the actual panels.
On one hand I get it; panels are very simple, robust devices, while inverters need to interface with the grid and usually have network connectivity and so on. On the other hand, there's a lot less material in an inverter, and they're still relatively simple electronics? Which we're pretty good at mass producing cheaply. You'd think there's a lot of room there to get the cost down.
Perkskovites to name one tech, will probably be a generational shift in solar panel technologies, the US would be stupid to miss it if they want to be a future world energy player outside the slow inevitable decline of fossil fuels.
For who has the stomach to fund it, there is available maybe another order of magnitude in cost performance in solar, and say two or three orders of magnitude of cost performance available in batteries?
