Multiple buildings with separate solar

Hi,
      Is it possible to have more than one system feed my acreage from multiple sites if I lose main line provider? I want to get into Solar as a backup but have multiple buildings and more than one solar system in storage to be used in the future. My idea is that all buildings would have access to power from all the solar sources as a collective?

Any suggestion?

Please help.

Thanks!

I didn't find the right solution from the Internet.
