My DIY Solar Panel System Total Cost and Comparison to Quoted Install

I made a detail breakdown of my 9kW DIY solar panel system total cost, including all the hidden unexpected costs, and compare that to the quotes I received to have it installed by a professional solar company.
I used Unbound Solar, for the solar components and Ready Rack for the racking system. The suppliers mentioned are the ones I used based on my own research, I received no discounts on my components.
