We have a pretty basic set-up; 90 Watt, roof-mounted solar panel, 2 6V Golf cart batteries, Renogy Solar controller and modified sine inverter. We usually boondock, don't watch TV and are pretty conservative on electric use. This past summer we camped (boondocked) for over 7 weeks and never started our generator. Your needs may differ and, as BB&LAB pointed out, you'll need to determine your needs first. We're very happy with our setup, but I would recommend getting a true sine inverter so you can use delicate electronics. As I mentioned, our controller is from Renogy and they really stand behind their products.
