I live in Texas now where there's a lot more sun and a lot more electricity usage (though it's cheaper per kwh). Panels and inverters are a significant percentage more expensive due to tariffs and stuff, but that's not even the biggest cost driver. It's the permitting and installation costs that make it so so so much more expensive. If I could get a bunch of panels on my roof for $5k, they'd be there already. But typical costs I'm seeing is low five figures which is well beyond my appetite or electricity costs.
