I'm in the Seattle metro area and 25K to 40K is very common. They tell you all kinds of subsidies and payback periods but the out of pocket or loan is always in that range. And payback periods are terrible here given the weather.

My parents spent $18K on rooftop solar in the Boise metro area. One Tesla powerwall battery and install on top of that will be another $15K.
And the Powerwall is also a ripoff vs many other options. 5kw battery module can be for for 1.2k, so 3 modules give 15kwh for under 5k
depends on the market. The 5kw options i was quoted were Enphase 5p batteries, average price from multiple installers was $5k per battery installed.
Compared to this, 15kwh for under 5k https://midlandbatteries.com/products/dyness-15kwh-dl5-0c-ba...

Needs an inverter though, but if you have solar you already should be ok
