We installed roof solar (10kW panels + 8kW hybrid inverter + 32kWh battery + planning/execution) last October for 11k euro. After all the math, our "investment" would pay off in approx 8-10 years (at current electricity prices). That's without an electric car, which we plan to buy sometime in the next two years.
All in all, pretty happy. Especially that we have frequent grid faults. Even my ISP has some beefy batteries for their equipment, so much so that one 14-hour grid blackout didn't affect us at all and we were able to use the internet since we're working from home (FTTH + ONT, GPON).
Usual disclaimer, sample size of one. We're in Romania.
