Xringer,
The idea of using RF coax cable for solar panel DC is good (find new use for coax cable). There is plenty coax cable around the house. I was wondering is it safe to use existing coax cable for a low power solar panel rated 45W (12V about 4AMP)? I didn't understand you concern about arcing. Is arcing also an issue for 45W low power solar panels? I am thinking to use the exiting coax cable to connect the solar panel to the charger controller which is inside the house (about 50 feet). Any comments? Thanks.
