If you are looking for a great way to go off the grid, Costco has a three panel, 55W solar system. The frame is a little flimsy as is, but the panels really do a great job even in overcast/cloudy conditions. For less than $200, you don't need to plug in. It was easy to hook up to the battery and comes with 12V and 110V adapters to power just about anything directly.
