I had one that was amazing but jumped. #2 was ALMOST as cool. Love these fish - it's like having a dog in the tank.
Thinking back, my 2nd one his for a while when I added it.
After Solar City noticed our system was under performing (3.4kw system was producing ~12-13 kWh per day), they came out and found that the inverter's 2nd zone was never activated. So 5 panels were just for looks since Dec. Now we are seeing 18-19 kWh/day.
