connect solar panels in series while sun is shining

[kayillerwhale]

At the risk of asking the dumbest question ever:
Is there any problem when connecting the solar panels in series while sun is shining? I'm not talking about connecting them to a consumer/battery, I'm just talking about the connection between two solar panels. Could it potentially cause any issues to the solar panels (because it already produces electricity). Shall I better cover them with a blanket? Sorry for this really stupid question.

No problem. You will have an open circuit all of the time as long as you do what you suggested.

No, this can potentially be a real issue. DC current flowing out of the panels has the ability to arc much greater than AC can, so you should not unplug a MC4 connection while current is flowing. Flip the breaker, or disconnect the battery though as DTh illustrates and you are good to do as you please. Make it a habit that flipping the breaker is always the first, and the last thing you do.
