Comment: Solar PV is grid sync'd... (Score 1) 735

I thought this was a really cool idea until I talked to someone locally why has a solar install on their house. They mentioned that most current installs use the local grid and syncronize the AC to it. If the local grid goes down, you are down as well. They don't have a battery bank either, rather rely on selling daytime power back to the power company, then doing the reverse at night, buying local power for the house. Unless you install a bunch of more expensive equipment, you are out of power when the local grid goes off as well.
