[QUOTE="Alan B, post: 550904, member: 37327"] [SIZE=4]I have some panels that would be around 15 years old ,when it rains they trip the AC 30 ma house circuit breaker [63amps]. after the isolator is turned off i can reset and all is well . where and how would i begin to test ,they are set up as two strings of 7 panels . I replaced a few that had visable corrosion at bottom end of panels . they are 175 watts a piece at around 6amps ,the backing paper has changed from white to light brown . I have a basic multimeter but am a novice . regards Alan[/SIZE] [/QUOTE]
