Follow These Steps to Disconnect Solar Panels:Check to see if your system has a disconnect switch. If not, cover the solar panels with a reflective or opaque surface.Use a voltage or multimeter to make sure the voltage measures zero.Disconnect the wires. MC4 connectors make this easy, or you can use a socket wrench.Remove the bolts and clamping devices, if applicable.
Turn off both the inverter and the solar array main switch to cut off the flow of electricity. This reduces the risk of electrical shock during the disconnection process.
Disconnect the AC and DC switchesInspect your system to check if it has a disconnect switch. If not, place a reflecting or opaque surface over the solar panels.Verify that the voltage is zero by using a voltmeter or multimeter.Unplug the wires. This is simple using MC4 connectors, or you may use a socket wrench.If necessary, take out the bolts and clamping mechanisms.
Solar panels should be disconnected by first turning the solar disconnects to the off position, both on the DC and AC sides. The wiring connections between panels should then be removed.
