Batteries are dropping fast in price, but for the USA, they might be going up because of tariffs. Neatly sidestepping that: I have a powerwall 2 with 5kw panels, which I've had since about 2021. At the time it was the biggest, cheapest, had a grid isolation mode, and could be mounted outside. (I didn't trust tesla back then, and I sure as shit don't now. Moreover, once it catches fire, that shit aint going out anytime soon) It still cost about £7k installed. From about march/april to end of october, we are power sufficient (london, even with rainy days, gas hot water though.) If I were to get a new system, 13kwhr of battery is something like £2k, plus inverter/charger. The panels are dirt cheap, to the point where the scaffolding costs more than the panels. (and the mounts.)
