Pv panel 0 volts and amps and a strange suggestion from the service

[elias]

Hi,
I noticed that after a week of installing a pair of 100w solar panels , one of them reads 0 voltage and 0 amps in sun . I tested directly from the junction box on sunlight . The service guy says that he will change it but suggested to wait 2-3 days and it might "wakes up" itself

Sounds like a faulty connection or dead panel to me. I had two 100 watt panels fitted and neither of them ever needed a wake up call, but maybe the person who fitted them for you does !!
