I really need to take that AI class. If just only for the knowledge and self improvement.

Why assume an outcome of a valuation? Why assume the outcome favors a cause? Why insult the appraiser who applies recognized, accepted appraisal methods? Why assume their inputs and analysis are not appropriately developed and used? Why keep guessing here?
Is the state reporting the most prevalent options chosen buy buyers? Because that right there, is the evidence of the "market value" of existing systems.
That can be the market value of the systems, but the appraisal assignment is find the market value of the real property- and then the solar system is considered in its contributory value to the whole. (which might be different than what buyers are paying for solar system as a stand alone retail purchase.

zackly… if "owned" the system cost is not relevant. The payments are not relevant. The maintenance costs are marginally relevant in the same sense as the other short term obsolescences found in the house, and not many people address those short and long term items outside apartment appraisals.Sunk cost.
Easier to prove 2 + 2 = 4 than it is to prove a unicorn "adjustment" based on "paired" sales when such pairs are a convoluted mess. In those cases, you have SUPPORTED your adjustment clearly when neither method can PROVE it.2 plus 2 equals four
No assumption at all, it's only data points,
which options did buyers chose, is no different than how much did a buyer pay for a different property.
'Cept, with the property prices, the buyer has wider options, not limited by the state. And, the seller has choices of different buyers.
With solar income/savings, the options are limited by law and regulation and differ from one utility company to the next. And, the buyer is limited to only the utility company connected to the property. No other buyer, No other options..
