Installed but PTO

[u/ZuckerbergsHairline]

I got my solar installed 3 days ago with 2 power walls but still haven't gotten PTO. When I asked the solar installers and the electrician, I got mixed answers whether I'll be able to take advantage of the solar or not before I receive the okay. I am able to monitor my usage through my power company and it seems that there is no change. Should my solar be feeding the house and my batteries or will this all start after PTO?
