solar energy design software

Options
Hello, I've been looking around for a software package that can assist with the design (and simulation) of a PV system with a graphical interface. Does anyone know of anything like this? I've searched all over the internet w/o any luck.
Thanks,
Greg

    This one seemed to be pretty accurate (compared to my 3kW Grid Tied installation)... Mostly, just fill in the numbers and some graphs of costs/savings/loan costs...

    What is it you are looking for? CAD drawing of a system overlaid on a home, accounting for shadows, utility usage, etc.?

    Yea, something with CAD for system positioning, layout, and maybe component compatibility, etc.
