most buyers are afraid with much technology, if it looks slick and shiny,
it has many parts that can/will break and will be expensive to
repair/replace plus the new homeowner may not have skills to perform
maintenance/repairs.
until solar PV is off-the-shelf type purchase from home depot, I would not
calculate an "add" value to such a system as it's been a turnoff in my
experience. in fact, I won't even mention it in initial walkthroughs, only
when there is a serious buyer and then it's sometimes resulted in loss of
sale (someone else always bought the place)
I agree with Justin. I'm not in the Real Estate business, but that's been
the experience of the other member of our local Solar technology group.
Note that you've asked two different questions - appraised value and resale
value are often quite different. PV might add to the appraised value
without ever adding to resale value.
Passive-solar homes & solar hot water, that reduce energy consumption
without adding a lot of technology (or the technology could fail without
you ever seeing any difference except in your fuel bills) might add value,
but PV, I don't think so. I can't see a lot of people being impressed with
my DIY PV
