I'm about to get quotes on replacing the asphalt shingles on my roof and I'm wondering about prepping the roof for solar PV down the road.
While they have the shingles off should I put thicker boards in place to handle the load of the solar panels/racks/etc or is it likely a non issue?
I'm thinking energy star shingles and in my state that comes in a whopping 1 color choice (white, white, or white). Any thoughts on white roof and how that interacts with solar PV?
OK so the general questions are there, let me know if there is anything else you would check or ask for as I'm getting quotes from contractors in the coming days.
As to details 35.934,-84.0749 is pretty close to me if you like to punch it into a solar calculator. Kwh per month for the last few years are roughly Min 600, Max 1700, Avg 1000 but that is with no charging of hybrids or EVs and I'm likely to change that in the near future. House built in early 1970s most likely with the cheapest possible materials but nothing truly substandard (it is in a good neighborhood but obvious the developers built to a cheap spec).
TN doesn't play nice with solar PV in general even though we get good insolation see http://www.simpleenergyworks.com/tva-ki ... steps.html

But I figure it'll be cost effective to grab some solar PV and put it on my roof well before the end of the roof I'm about to put up so I'm looking ahead.
