Wrenches,
So a follow/add-on up to the last post.....
So do any of you add the cost of labour for removing and replacing a roof top
array, to be included in the "life cost" of a PV system, since it is reasonable
to assume that a well installed array will outlast any asphalt shingle roof,
and re-shingling around the array is not recommended since no roofing company
would warranty this work?Just as informing an off-grid client that the
batteries will not last as long as the charge controllers/inverter/array, and
will need to be upgraded from time to time, so it will be a system lifetime
ongoing cost to consider.
Thanks,benn

Subject: [RE-wrenches] Re-shingling roof
Hey Wrenches,
I know it has been discussed on this list, but i'm not having any luck finding
any threads on how to deal with re-shingling an asphalt shingle roof with a PV
array already on it.
I have a potential client who is asking (somewhat concerned) about this
scenario and i'm looking into what suggestions i can offer. Their roof is only
3-4 yrs old now.
Depending on the condition of the roof when the system is installed, is
re-shingling around the array an option, since it will have been somewhat
protected from the sun/rain/snow? ... or is that just a bad idea and not
something that should be suggested (re-shingling around the array)?
If anyone can recall the name or date of a thread on this topic, i'd appreciate
being pointed in the right direction. I'm sure i recall in one of these
threads, WM talking about his custom(?) mounting method that allows for the
array to be easily tilted up to allow access underneath.
Thanks,benn
