Can you get power from solar power even when there is a blackout?

Yes, you should be able to use energy from solar panels, even when there is no electricity in your area, depending on how much power has been stored by your panels. Also, some solar panels combine there power with that of your normal electrical power and, in that case, you might not be able to. In short, in really just depends on your situation. I would suggest trying it next time your area power is out.
