[RE-wrenches] solar lease questions

[Darryl Thayer]

Hi all,  not enough information.
Does her grid allow export?
Does she have a period of poor sun?
What is her daily or monthly consumption?
Is there an AC  or DC limit on connected solar power?
Will her AHJ or Utility allow line side tap?
The system seems to be poorly designed.  Power Walls are AC coupled, the
large array would clip all day and only have advantage in the shoulders, a
smaller array and bigger inverters?
This design depends upon Utility and AHJ   thank you have a nice day.
