Comment on How I Installed DIY Solar Power and Started Running My House on Batteries

See:
Arizona, USA:
Soak up the sun: Impact of solar energy systems on residential home values in Arizona
In particular, properties with electricity-generating solar panels enjoy an average premium of approximately $45,000 (15% of medium home value) and transaction price premium of $28,000 (17% of medium home sales price).
California, Connecticut, Massachusetts, and Oregon - USA:
Solar at High Noon: Solar Home Premiums in a Rapidly Maturing Market:
We find clear evidence that solar systems are correlated with higher selling prices if those systems are owned by the homeowner (HO). Alternatively, we find no value or slightly lower values associated with non-owned panels
Southport, Australia:
House price premium associated with residential solar photovoltaics and the effect from feed-in tariffs: A case study of Southport in Queensland, Australia
Using the hedonic approach, the study found that the gross premium was 4.3% of the average house price; the average net premium (exclusive of the PV installation cost) was 21,403 AUD when the FiT was at 44 cents/kWh; when the FiT dropped to 8 cents/kWh, the gross premium fell to 2.4%, and the average net premium dropped to 5600 AUD. The study shows that a solar PV house does enjoy a premium in terms of property value and indicates that a higher solar rebate and subsidy leads to a higher premium
If energy efficiency increases by 100 kWh/m2a, prices increase by 6.9% on average […] there is evidence that about 98% of future energy cost savings are already reflected in a higher housing value under myopic expectations regarding future energy prices.
Italy:
The Market Price Premium for Residential PV Plants
Our results show that individuals are willing to pay an additional price for a solar home, and the average market price premium is equal to 2.69% for monocrystalline PV plants and equal to 3.08% for polycrystalline PV plants respectively.
UK:
Returns to solar panels in the housing market: A meta learner approach
Our results point to a selling price premium above 6% (range between 6.1% to 7.1% depending on the meta-learner) associated with solar panels. Considering that the average selling price is £230,536 in our sample, this corresponds to an additional £14,062 to £16,368 selling price premium for houses with solar panels.

So to do an accurate property value assesment (what you’re doing) you’d need to provide at least 5 examples from each of those regions, only including comparable properties.
I’m not saying solar doesn’t improve property value.
I’m saying you cannot take one example and apply it to an entire market. Which you just did x6.

Exactly, and all studies take that into account and use the same hedonic price models which most appraisals rely on.
Apologies for not providing links to some of those locked papers, as Anna’s Archive is down right now, otherwise you could also dive further into their methodologies
Which is not the case with these studies, as explained above, so once again, perhaps you are the one trying to generalize your local market to everywhere else?
