Garden setup relative to sunlight

Hi guys

I really want to set up a food forest in my backyard. But the house will be tall and the front of the house is facing southwest, more towards the south axis. Is my backyard going to be blocked from sun since it's facing northeast (more towards the north axis), or can I face my plants to grow east to west?

I'm wondering if my orientations are good since there are more weeds in the backyard and less in the front, does this mean there's more sun in the backyard?
(since I'm not always at home)

Sorry I get confused with all the internet information, some ssay solar panels should be south facing, but another youtube video said plants should be taller in the west direction,

Thanks!
