are you or anyone in your company certified by NABCEP? QUOTE]

Yes, one is. I am looking into it for myself but can't say if it is worth it or not. I think it may be comforting to some customers.

When talking about "selling power", keep in mind that the utility will pay you far less than what they charge you. Therefore an economic analysis regarding payback is very important.

Er .... well..... ah .... no kidding. :smile:
 
Grid tied systems used to be difficult as the utility had to set the protective relays and metering- electromechnical relays and such. Today the solid state inverters, such as trace make it much easier.
However you still need to install per the POCOs requirements and NEC.
You'll need grouped disconnects and signs.
What is hard about working on the PV panels the DC disconnect is fed from both directions, DC from the array and DC from the battery (if one is used)
To turn off the panel you cover it up.

That gap has been narrowed.

And as far as the economic analysis regarding payback of course it's important. Some of the panels we will be installing add R-10 to the roof and that is also factored in. :)
