Adding more solar is a question of adding another panel.
The inversion loss is a small price to pay for safe power. [2]
DC is probably not coming back as a way to wire houses and buildings.

- antisthenes 5y agoDC might come back as a separate in-tandem network specifically for ceiling LED lighting. It's more convenient to simply plug into a low voltage DC current wiring with a LED fixture than to install a AC-DC converter. It's certainly something I've entertained doing for my own place.

- KaiserPro 5y agothe thing to really highlight here is that having microinverters on the back of each panel increases overall efficiency when even a single panel is partially covered (either by leaves, poop, or damage) otherwise you chain a bunch of panels together in series and track the max power point there. This means that you don't quite optimise for each panel
