I have an old panel, don't know how many watts.
The 2 first minute is normal but then the solar panels output is strange. The ampere/watt behaviour is jumping constantly after the 2 first minutes.
If I reconnect the panel it takes just seconds before the strange behaviour appear. If I wait e.g. an our befor reconnecting it behave normal for 2 minutes again.
I have changed the cable and checked the connections. What can be the reason for such behaviour?
