Yo, Mechanics~
A client is considering a "biggest ever for me" battery based power system.
They will probably scale down their ambitions once the cost realities settle
in but for now they've asked me to look for battery based inverter systems
which can scale bigger than a triple stack of Xantrex X
It took a little bit of doinking around, but I did finally find it.

You must be careful about the thermal conductivity of the attachment
method. These pads, part number is TAP, are made of Kapton, and
provide some level of thermal insulation. I have some on my array that

3m has a line of "double stick tapes called VHB: very high bond. The
adhesion is very strong; these materials are use by commercial glaziers to
stick glass onto the exterior of buildings.
Some of the tapes are very thin so they would not slow the heat flow into
the sensor very much. If your temp s
If you want to mount it once and not take it off ever again, why not use a
good polyurethane caulk like Sikaflex? No VOCs, no acetic acid. You could
hold it in place with electricians tape while it cures which should be less
than 12 hours.
To be 100% sure about using any sort of adhesive, you mig
I second Dana's suggestion. We've used high-temperature foil tape on PV here (for attaching temp sensors), and it's been working for years. I'm aware of two grades: the kind with soft sticky foam; and the type with a moderately solid (but pliable) adhesive ours was gray in color). We use the lat
Have you tried the aluminum foil type of duct tape with the
peel off wax protective paper over the adhesive. It seems to
be virtually impervious to heat or cold, though I have not
tried to apply it to the back of a PV module.
I keep it on the raft for all sort of repairs that get very
hot & wet.
Hello Wrenches,
Does anyone have any good ideas for mounting thermocouples or RTD's to the
back of modules for cell temperature measurements?
I've seen electrical tape used (obviously the results were terrible),
thermally conductive epoxy from Omega Instruments ($$) used, some kind of
foil tap
