Rhetorical questions to follow:<br><br>
If you do not provide string calculations, how do you verify that Voc
will not exceed NEC limits? How do you verify DC feeder
ampacities? Does your jurisdiction not verify such
parameters? We know you have a handle on these factors, but
how about the Johnny-come-latelies trying to take your business?
Should they not be kept to uniform standards meant to protect the safety
of the consumer (and ensure fair competition)?<br><br>
Can you really expect a field inspector or the customer to verify these
parameters? I believe all of these issues are best handled by
stringent plan check.<br><br>
What is more important to you: saving a few bucks in permit fees or
preventing house fires?<br><br>

My standard permit docs are comprehensive, but do not
include documentation regarding string sizing, thank goodness. A
permit technician/ plan reviewer should not be overseeing string
sizing. You should be thankful that the permit fees are so low,
because that is the best thing a jurisdiction could do to support
PV! <br>
Any fly-by-night, incompetent installer can check
string sizing on the inverter manu's web site. I would suspect
that, regardless of the plan review process, the less experienced
installers will still be accountable to the inspector and their
customer.<br>
