A single Powerwall used to be $11,500 and each thereafter $7,500. The reason being a $4000 Tesla Energy Gateway was required to manage incoming and outgoing energy for the first unit. Current price first Powerwall is $12,850, additional Powerwalls are $8350. And while you degrade the PV system 1% per year you didn't account for future energy prices. $2600 degraded 1% per year for 30 years is $67,677.90 not $58,000 (which is 30 years at 70%). While PV is not the clear cut economic choice of a 30 MPG vehicle vs 20 MPG, the numbers are close enough one can not ignore. But not so good as for mandates from Beloved Leader.
I figured there'd be variations in math, but as you note, they're not world-changing. But, future energy prices are part of the coercive element of this, as I footnoted. There's no reason for them to be higher (inflation excluded) if the energy market were unfettered, so it's not quite right to judge PV's merits simply because the government is driving other prices up. Plus, we are truly one president away from that all flipping.
In addition to the costs that should be expected from the moronic expectations of "savings" from the installation of residential panels, in my part of the world hailstorms are to be expected. The cost and logistics or replacing damaged panels as well as a new roof underlaying them would place the "investment" so far underwater that a typical homeowner would see no chance of recovery.
Another excellent piece! Very convincing!

And you have to cut down all your trees so they dont block the panels. Thats real environmentally friendly.
