As a precaution I've used silicone on the bottom of a meter, where the bottom drop enters. This build up of silicone would prevent water from travelling down the conductors like a waterfall into a panel. Does silicone have any long term effects on the conductors, or SEU. I hope it's not bad for the insulation.
Thanks

Can't help with the silicone deterioration question, but I have a comment.
How is the water getting into the meter pan?
The pane should be relatively water tight; the conduit or cable entering the top should have a "WP" connector, and/or a hub. The head should prevent any rain from entering the conduit/cable. The "drop" drip loop should prevent water from "crawling" into the cable/conduit, or conductors.
As to the water flowing like a waterfall into the panel, I think you should seek the source.

The above is MHO, and please don't take it as sarcasim.

I've wondered myself about the effects of silicone on electrical conductors with regard to 110.11, or 110.12(C).
If you want to be certain, GE makes an electrical grade silicone sealant (RTV 162).McMasterCarr.com will help you find it.

Most WP SE Cable connectors are not all that WP after all. It is common to see an application of DuxSeal around the cable entry to help effect a good seal.

The electrical grade silicone is because standard silicone gives of vapors that are corrosive to copper and other electrical components while it is curing. I don't think it has anything to do with damage to the wire insulation.
