yes I meant it. the OP is referring to specific wiring for an unknown load and/or device. Designing a clear path to allow any future access between these points is far less costly and far more useful for future use. As to the 12/2. Any electrician worth a damn designs the system for future use. More space in load centers. More total load capacity than currently needed. And a 12/3 to the attic junction box is almost always done.

They are connected through a safety interlock. If you just tie them to the main panel then you'll potentially electrocute linesmen working on what should be cold wires.

There is one interesting device I read an article on. It's a little box that the panel plugs into. Then the box plugs into an outlet. The interlock is somehow built into the box. It feeds the power from the solar pannel onto the grid (reverse metering). It works even places where reverse metering isn't legal, so the Mother Earth people called it Guerilla Solar. They said it was so costly that the payback period was silly long, but they liked the idea anyway

I can't see how you can run wire now to connect an unknown solar system
They can range from a few 200w panels up to an 8,000w setup + higher
The 1st one you could get by with 12-2 run, the 2nd depending upon the setup you would need 4 12-2 runs or one single higher gauge run

My future system will be wired thru the attic, so I have access
If I did not (have access) I would not run wire for something that is unknown

Many people ran CAT3 runs years ago for computer devices & the runs were never used
A complete waste of $$ at $90 a run in commercial buildings

You can supply DC to a house
There are underfloor heating setups that I looked into that use striaght DC power from solar panels
But here most people use an inverter & covert the power to standard 120v power for use

People do use DC - usually when they are off grid, cabin in the woods etc
