Yep. I also live in Los Angeles County and am currently producing 36 kWh with 19 panels, so they should definitely be closer to 40 kWhor they just flat out forgot to connect the second string. The output is not adding up they are actually in parallel. They clearly can't be in series since 24 of those modules would exceed the voltage input. Power production should be closer to 40 kWh for the day vs 20 kWh.
