Wind would be particularly effective in Switzerland and it's fast to deploy. The swiss grid has less than 1% wind which was pretty shocking to me. It seems like Switzerland has a particularly bad renewable story for an EU nation.
The really awesome wind spots are more the coastal or offshore farms, which... well... we can't have (no access to the sea does that to you).
Solar is really really booming right now however, many houses take themselves off grid completely. Mine is a net producer for example.
All year? And do you mean you "inject" more than you "pull", or do you mean that you can live without ever pulling anything from the grid?
Because "being a net producer overall" doesn't say that it would work in practice if everyone was doing the same, right?
I have a 40kWp system and a 20kWh battery.
As such, as of now, the EU can shut down Switzerland without warning if the grid is overloaded and they need to avoid a blackout.
