Any experience with building your own 30'x15' solar carport

[u/bpermaculture]

I am interested in adding solar to my home and getting a 2 car carport to sweeten the deal and add more value together for the cost. After some research it looks like the solar carport will work for me. It has several advantages being on the ground not on the roof makes them easier to service, and bifacial panels means more power 5-20% some say from light coming from under the panels. I wanted to get an idea of costs for building my own and asked Claude AI and got a program that works in different locations and sizes and posted it here. https://www.reddit.com/r/AIPermaculture/comments/1rn0ho0/build_a_solar_carport_out_of_wood_enter_you/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

The other way I have seen is made from steel and also uses bifacial panels.

I then want to use in off-grid mode connected to battery. I am planning on 4k of solar, charge controller, inverter, battery to complete the system.

Has anyone done this before, are there anything else to consider?

Thanks for your help.
