I live here in Nigeria where electricity has been epileptic since I was born (I'm 23 now). Like, I live in one of the nicer suburbs in my state, but 12h of power isn't guaranteed. So, last year, I spent $7k on 8.4 KW of panels (400W * 21), an inverter, and 20KWh of batteries. It's been life-changing. I've been able to go completely off-grid. Like, I disconnected from the grid (i.e., my meter) completely. And my usage has gone up to around 50KWh daily (air conditioners, fridges, etc.) but it hums along day-after-day. That assurance that the power won't trip off while I'm on a meeting with a client has done wonders for my mental health among others. Just reliable, stable power. And, given that I used to pay $0.12 per KWh, the whole setup will pay for itself in 2.7 years. Just under two years to go. |

I live in a place with cheap and stable hydropower. There's winter time price spikes but average solar earnings compared to grid cost from solar during sunny months would be pocket change. In winter solar would give virtually nothing.
The overwhelming conclusion was that instead of buying a pile of hardware to install, configure and maintain I will earn more by clicking a button that puts it as a financial investment into anything with more than 2-3% annual yield and just paying the electricity bill and reinvesting whatever is left over.
I wanted to find an edge case that would make me feel smart for buying a multi kWh home battery but with the exception of a market apocalypse or the likes every outcome suggests that I just put it in dividend stock, high interest savings accounts or whatever else until either power prices increase tenfold or $/kWh for batteries drop tenfold.
