  Kent, I'd suggest you follow the same procedure I used before I had my solar 
power system installed.I had my installer give me the names & addresses of 
three previous recent installations he completed and asked him to clear my visit 
with each customer.

I don't have a Tesla system, but a neighbor about a mile away does. During a visit, he allowed me to poke around the system, which had recently been installed, with my Kenwood TH-F6A talkie. The wiring was either buried or in conduit, and the batteries were on the side of a concrete outbuilding. His pre-existing solar array, was on the other side of his property.

That talkie is not very sensitive, so is only useful as a probe close to radiators. I couldn't find any noise. That doesn't mean there isn't any.

FWIW, the TH-F6A can't hear any noise around the charging cable for my Tesla Model 3 when it's charging, and neither can my RX on a 160M vertical that's about 40 ft away. I have a TH-F6A installed in the Model 3 with a vintage 2M/440 talkie amp that has a preamp, and it doesn't hear noise. I've seen reports from a ham on youtube who seems reliable that an HF rig in his Model 3 only hears noise with regenerative braking.
