This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

$16K in parts, PE drawings and tree removal. With 30% of that back in tax rebate. I did the install myself with help from my wife. 11.64KW DC worth of panels. Anything more than 11.7KW and I would have gone from class 1 to class 2. I didn't want to deal with all that required.
My degree is in computer engineering and I used to work in power generation so I was very comfortable with the electric design and working with high voltage and current. You might not be so comfortable. A similar system without battery was quoted to me at $24K by an installer.
Battery was about $2K. Tree was $1K. After rebate cost was $11.2K. It's reduced my power bill by about $210 a month. So about 4.4 years to break even.
It was a lot of work on my end but I know I didn't cut corners and was very careful to make a system that should last.
