If you want to power your home by the sun and even sell some of that power to the local utility company, you might be in for a rude awakening if electricity is out for an extended period of time. You’ll want to be sure you choose the right option for your needs.
So how do you know which solar power system is right for you? Jeffrey Yago presents an informative overview in the March/April, 2013 “Backwoods Home Magazine” (Issue #140). I’ve put an excerpt below with a link to follow so you can read the whole thing.

Several weeks ago I received a call from a woman in Florida complaining that they just had a power outage lasting several days and her solar system quit working. Although I had no idea who she was and never had anything to do with the installation of her solar system, she was very distressed and I wanted to at least point her in the right direction.
After a few questions it was clear that what she had purchased was a “grid-tie” solar system, and these systems must be “tied” to a working utility grid to operate. These systems do not have any battery backup capability, so their only function is to sell solar-generated power back to the utility grid, which offsets some or all of the metered usage for a given month. Any month the solar-generated power exceeds metered usage of the homeowner, the utility will credit this excess towards a future month when the utility demand exceeds solar generation.
