If the OP's jurisdiction allows supply side taps for PV, then a panel upgrade is not necessary and the extra cost would be minimal. That part of the work would still have to be done by a licensed electrician though.

FYI I have seen several "line side tap" adapters used in installations around here. They are basically a fused adapter that fits between the meter and the meter socket and allows direct connection to the incoming line.

Hey guys when you talk of a panel upgrade are you talking my main and sub panels?

If the PV backfeed is into a sub panel you may or may not need to upgrade that panel, but if your main panel is 200A and the backfeed is more than 40A you may need to upgrade the main panel and maybe your utility service.
(Most POCOs will allow you to upsize the panel and keep the same service size. Los Angeles LADWP will be totally anal about it and insist that you match the service size to the panel size even if you use a main in the new panel which is no larger than your old service size.)
The details of what is required at the main panel are more than I want to go into here. Check the stickies and post a new question if you do not find the answer you need.

Ok ignore that. I found some reading. Although I'm not sure I understand! Obviously a question for my installer.

That is an excellent Price. I work with a dealer and the best we normally can do for a system that size is 4.00. Then you will also need a panel upgrade for a system that size. So if thats an all included price, go with it man. Its excellent.

That's the quote. We will see if there is price creep.
