I plan to build Lean-to Greenhouse next to my Storage shed. It's going to be 6Ft Wide and 4 Ft Deep. I plan to use an Adjustable Angle Flange Where the Red line is on Shed. I need some ideas if it will work or if I should go a different route.

I would also use the adjustable angle connectors on the west side of the uprights that will connect to conduit attached to the flanges on the shed side. Also depending on wind conditions it might be a good idea to make sure it's anchored to the ground or weighed down with something.
I am in California; I Don't get much wind or Rain, and no snow. I am planning on adding Old Windows I got for free, debating how should i add that. I think 30in earth anchors can also use sandbags to weigh it down. On the Shed side, there is a 4x4 under the door I can mount to that.
If that concrete wall is to the south, you're going to be shaded pretty much all the time, your greenhouse would keep warmth from the roof but not the direct light that plants crave. What are you going to put in there?
Yes, that is true, but in summer, we go 100+, and in winter, we don't get snow or rain, but we get frost, so I am growing tropical plants like guava. Mango Lychee frost kills those. I will be using Polycarbonate Sheet, so there will be lots of Light from the top and west side
That's good. I have a lean-to style green house that has stood up to ice storms, so structurally I think you'd be fine, especially with that small of a footprint
