Skill? If you can use a screwdriver, and lift 50lbs, you can do it.

1) Throw the "DC Disconnect" switch to de-power the panels. 2) Unscrew old panel from rails. 3) Disconnect MC4 connectors (with fingers). 4) Remove old panel and install new panel. 5) Connect MC4 connectors. 6) Screw panel into rails. 8) Throw "DC Disconnect" lever to re-power panels.

There's also a step 7 where the panel needs to be connected to the ground of the other panels, but with modern systems there's these metal clips that just clip onto the edges of adjacent panels to make the ground. Your system may be different but the ground is a pretty simple connection of metal to metal.

Here's a YouTube short showing it: https://youtube.com/shorts/fpyXHsZCb6M?si=JHoYfff2yz3ZsA9P
