Following the inverter shutdown, locate and activate the main DC disconnect switch, often found near the inverter or the main service panel, to physically break the connection between the panel strings and the electrical infrastructure. . Working with solar photovoltaic (PV) systems requires recognizing that the panels generate power any time they are exposed to sunlight, meaning the system is always “live” during the day. The mandatory first step is to isolate the power source, beginning by switching off the main inverter, which. . In this post, we'll explain how to disconnect your solar panel and provide the following suggestions if you're new to solar power. Try to make the disconnection at dusk, if at all possible when the panel output is low. Solar panels generate electricity when. .
