Would it be enough to run my fridge and the lights off of it?
How big of a battery would I need to install in the basement and how long could I stay off the mains and stay on solar?
Or will I save money by partitioning circuits in the house to Solar PV and keeping the hgih-load stuff (fridge, dryer) on the mains while ceiling fans, lights and computer equipment run off solar?

I have a single, split level with a southern facing roof.
Many people have the same misconception about Solar Power. You would still be hooked to the grid. While the sun is producing energy, you will see your regular meter spinning backwards (depending on the amout of PV you have). You will also have a PV Meter before your utility meter showing the Kw's produced by your panels.
PV does not distinguish between high load and low load. It merely produces energy. As for battery backup, most homes do not have enough roof space to provide 100% of your daily use let alone enough to store excess power.
