Hello Wrenches,
I have an installation of 165w PV on a pole mount that was exposed to a fire
from the rear when the customers shop burned. 6 of the 10 panels survived with
only replacement of the MC4 plugs required but one of the panels that is still
functioning had the rear coating melted off.
You could probably use a spray on roof sealer or membrane.

You might try the Plasti-Dip stuff used to coat tool handles. Would be
expensive for an entire array, but a can should cover one PV module. We saw

It's been my experience the only adhesives that work reliably on PV backsheets
are those designed for the purpose, such as Dow 804 et. al.. Substances such
as silicone sealant, tool polymerics, and others will appear to be suitable
when first applied, but they eventually peel loose over

A silicon based spray sealer should work, just make sure whatever you use
is air cured and not accelerated cured by using acetone or some other
solvent that may get trapped and eventually cause corrosion of the cells or
cell interconnects. Even if it buys you a couple of years that is better
Hello Robin and boB.
Ryans Midnite video of the Birdhouse and rapid
shutdown disconnects is amazing. It does look
like you are producing a means of implementing this new code rule.
In many situations, the rapid shutdown
requirement certainly makes sense. In a large

Hi Ron- While I agree with Dan of Exeltech that it would be best to just replace the damaged panel, if you want to try salvage you might want to use a conformal coating that is commonly used to seal PC boards. Conformal coatings can be sprayed or brushed on. In your case a brushing may further
