Probably not. If you have solar and the power goes out, your power will go out, too—unless you have a backup system. This is because U.S. electrical code requires rapid shutdown of a solar system to protect emergency workers and prevent dangerous backfeed current from passing onto distribution lines.
In a blackout situation, the power from your solar panels goes nowhere - unless you have some way of storing the electricity (with a battery) or otherwise cutting your system off from the grid. In this video Will White explains what it takes to ensure you have power with solar during an outage: How can you use solar power to survive a power outage?
Causes can usually be narrowed down by first determining whether your solar system has a lower power output than it should or no power output at all and troubleshoot your solar yourself. If your solar system has suddenly started to provide no power the most common cause of this is going to be an issue or failure with the inverter.
This is to prevent electricity from being fed back into the grid while utility workers are trying to repair the system. Therefore, even if you have solar panels installed, you won’t have power during an outage if you have a typical grid-tied setup. To address the issue of power outages, some homeowners opt for hybrid solar systems.
Those with micro-inverter system setups can usually rule this scenario out as a possible cause for no power output. Again, in this case due to the cause being a damaged component of your solar system it is best to have a CEC Accredited Installer inspect your solar panels and determine a possible solution.
A Loose Wire On Your Panel Array If you are experiencing a significant loss of power this may be caused by a loose wire on your PV system which means that your solar array cannot connect the energy it’s generating to your inverter system. Ensure that you call your installer to do this for you as live wires can be dangerous.

PV intermittently dropping to almost 0 W
My 5kVA Mecer inverter has started dropping the PV input while the sun is still shining brightly outside and the load fairly constant. The PV input drops to almost 0W then in picks up again to the value it was before the drop. It does this at least twice within 30 seconds and then seems to settle down again.
