Thanks icarus for pointing out that the only way to go 100% off-grid with a PV system is to either install a lot of big expensive battery storage, or stop using electricity whenever the Sun isn't shining.

And a big second to chogan2's remarks on radiant barrier. We installed one when our roof was replaced 15 years ago, and it reduced A/C season electricity use by 20%.

Just to add a point. PV of any sort needs "battery" in nearly any incarnation. In a grid tie situation the " battery" is the grid. With out a stable grid or battery no inverter in the world will work well if at all. (an inverter converts PV or battery DC to useful AC.). You can run a few things directly from PV DC, most notably fans, but very little else.

Hope this is clear as mud.
