Context: I’m in the Netherlands. With taxes, power is around 25cent/kWh for me. For reference: Amsterdam is around a latitude of 52N, which is north enough that it only hits Alaska, not the US mainland.

I installed 2800Wp solar for about €2800 ($3000, payback in: 4-5 years), and a 5kWh battery for €1200 ($1300) all in. The battery has an expected payback time of just over 5 years, and I have some backup power if I need it.

I’m pretty sure about the battery payback, because I have a few years of per second consumption data in clickhouse and (very conservatively) simulated the battery. A few years ago any business case on storage was completely impossible, and now suddenly we’re here.

I could totally see this happen for the US as prices improve further, even if it’s not feasible today.
