a $20k invstment for 11 years at 4% would be worth $30k,......
$20k invested at 4% compounded monthly comes out to:
$31k after 11 years
$44k after 20 years
$20k in solar panels and investing the $150 saved per month at 4% compounded monthly comes out to:
$25k after 11 years
$55k after 20 years
Of course that assumes a lot of things, mainly stable returns on investment, stable energy prices, and minimal equipment maintenance.

Utility inflation in the modern era is around 4.6% avg. With solar you'll have insanely low O&M so thats a nothing burger.
If you buy the equipment outright, you're in really good shape. If you finance it, it gets more difficult but at the same time, they do a ton of savings calcs in the background to do the financing. Typically big solar asset managers require a year 1 customer savings. Depending on the finance vehicle, there may be an escalator but without one the savings gap get big pretty quick as long as you have a decent system and favorable irradiance.
