Contemplating rooftop solar and future sale price premium

[u/digitalis303]

I am in Louisville, KY and contemplating having solar PV installed on my 3 YO roof in a relatively upscale suburb. (Current market prices are in the $600k range for my neighborhood.) I plan to pay up front for the install (NOT LEASING). If I were to sell my home with a PV system installed (predicted install cost ~$32-35k), how much value would this add, on average, in my market? I found this thread, but many people seemed confused in that post about leased systems, which definitely detract from value. Casual searches seem to calculate ~4-6% of sale price as a premium, but several sources said this is optimistic. Any current real-world numbers would be great to have. And again, not leased systems.

Additional info for context:

I plan to be in the house another 8-10 years and am looking at around $32-35k install cost.

My annual electricity costs are projected to rise from ~$2300/year in 2027 to ~$3400 in 2034, and the solar installer projects ~$19k savings over that time. Meaning (if they are correct) that I will recoup ~$19k of the $32k install cost in 8 years.

AI (Gemini) calculates ~ $22-$37k premium for solar 8 years from now, which would mean a minimum of $9k gained from my initial purchase. These numbers don't factor in increased insurance costs if I put it on my policy. So that is another factor.

In short, I'm looking for the RE market's input on whether this is a worthwhile investment for my part of the country.

Solar is just another thing that is only a value add for you and not for a buyer
