“Our solar energy system occasionally shuts down when the sun is shining. Why is this happening and what can be done to prevent it?” Every inverter features a built-in mechanism that ensures it is automatically disconnected from the power grid when the so-called ‘grid parameters’ are exceeded.
If you live in a state where the National Electrical Code (NEC) 2014 or newer is enforced, your solar system will need to follow NEC rapid shutdown requirements to pass the final inspection and be connected to the utility and powered on.
Solar panels always generate electricity when exposed to light. But PV systems have a switch that can be turned off to stop current from flowing into appliances, and grid tied solar panels are automatically turned off during a power outage to protect utility workers. How Do I Turn Off My Solar System?
Yes, you can turn off a solar panel. Realistically, it’s unlikely that you’ll need to. For the most part, solar panels are only turned off when maintenance is needed. If you’re planning to do some maintenance on the panels or have some other reason for needing to shut off the power, here’s what you can do.
Solar panels are generally safe and reliable, but knowing how to quickly shut it off is still important. And in case your system does not have a rapid shutdown button, there are other ways to prevent solar energy from reaching your home wiring. By putting a cover on the solar panel, you effectively shut it off.
NEC 2014 requires all controlled conductors beyond ten feet of solar panels to be brought down to 30 volts and 240 volt-amperes within ten seconds of initiating the rapid shutdown switch.

Solar Systems Grid Down: Ensuring Solar Power in Outages
Solar panels consist of photovoltaic (PV) cells that convert sunlight into direct current (DC) electricity. This DC power then passes through an inverter, which transforms it into alternating current (AC) electricity compatible with household appliances and the power grid. Most solar systems are connected to the electric grid, allowing excess energy to be fed back into …
