Permit requirement and installer that will do DC rooftop solar San Jose CA

[Wiz33]

I'm looking to install a DC 6-8Kw solar panel system without micro-inverter that can get me a 400-450VDC drop into the garage for battery backup using a Ecoflow Ultra. I heard that a lot of the solar installer won't work on anything less than a complete system. If that is the case. Is there any permit requirement and is it possible to hire a contractor/electrician to set that up? Thanks in advance for any advise.

Hello again.

Do you need a permit to build a DIY standalone 4000w solar rack in the backyard San Jose CA?

It seems that most installer will want to install a complete power package. I have a fairly large backyard with a large area with minimal shading from trees and such. Can I just build a 10-12 panel structure 6-10 feet off the ground which also makes seasonal cleaning and repairs a lot easier...
