Who to use for residential solar?

[Jfed]

Hi brand new to this group and this is my first time posting sorry if this is was asked before.
I decide to finally pull the trigger and get solar. Who should I use in Long Island NY. I’m going to be tied to the grid.

so far I met with these guys

where do I start?

I’ll respond to myself and ask another question.
This is what is being quoted from the first place:
380w Q.PEAK DUO BLK ML-G9+
Microinverter IQ 7+ (240V)

is this a good system and can I add batteries easily via DIY?

can is switch this to off grid in the future if I wanted to?
