During the 80's we installed several SHW jobs on slate, one with 8 - 4x10
collectors. It continues to be leak free.
The key thing to remember is that it is NOT the slate that keeps the water
out, it is the tar paper underneath the slate. Here in Va. the paper is good
for about 100 years before i
Off hand, I can think of two components to this -- conductor heating, and
noise/impedance. From a conductor heating POV, the NEC is fuzzy on specific
distance but the general rule is to not bundle conductors for lengths
greater than 18', or standard derates would need to be applied. With the

With all due respect, I'm going to employ the bull*hit detector on this
customer's inquiry. He tells you that he wants the most efficient product
available, or potentially available in the next 5 years, no matter the cost.
He throws out the two industry leading commercialized, warrantable

We've done this with faux slate. Worked great. I see no reason it would
not work with real slate.

Hopefully, they are equally concerned about the energy efficiency of their

Hi, Drake~ Consider this item:

These are sized to match Eternit brand slates. I know very little else
about this...but if you have a different size of slates... thinking...
somebody else is out there with other sizes.

Hi Wrenches,
There was a strategy mentioned for slate roofs recently. Removing
the slate under the array area and replacing with decking and
shingles would certainly work. That might be the best solution.
There are two potential problems however.

You want to bundle with conductors of opposite polarity wherever
practical. This helps cancel the AC fields.

hello Wrenches,
Since we usually are using the batteries in back-up applications and thus AGM
batteries, we like to stack them. So we make-up a steel (2"X2" angle) rack,
have our tinner bend-up an enclosure, and get all parts powder coated.
Expensive, but last forever.
