17. Small-scale batteries are a thing too, even though the economics don’t always make much sense. 2024 battery attachment rates – proportion of residential PV buyers who get a battery too – were ~ 80% in Germany and Italy, ~ 50% in Switzerland, UK and California.

18. It is very difficult for installers and financiers to become large and long-term profitable in the residential solar and storage market. Margins are thin and there are diseconomies of scale.

@solar_chase@mastodon.green I'm curious whether this will be higher in California for 2025 as the remaining NEM2 projects make it through the system (disclaimer: I don't have details of NEM2 vs NEM3 by date handy, just that 50% sounds low given NEM3 incentives)
