100W Poly panel in Home Depot
Don't have a use for solar that small :), but I think the price isn't too bad. You'll have to order, they don't stock it in the aisles. Free shipping, and it is Poly. 100W

Arrays larger than 400W are usually made of bigger high-voltage panels. Cheaper per watt, more expensive controller, and easier install without rooftop junction box. Though they never ship big panels for free, you have to be near some solar warehouse.
I wasn't all that concerned with price per watt as much as I simply wanted a system that would perform in the conditions I wanted. Being the guy always asked to troubleshoot and sort out generator/solar issues for others, I very much prefer the flexibility of a parallel setup and PWM controller which doesn't get "confused" as easily. That little bogart SC controller has better adjustability and controllability that anything else I've seen available right now and doesn't really care if some of the panels are not producing as well as the others because of shading, tilt or what have you. Obviously if I was setting up the system on a fixed facility roof, or a tracking system my choices would be different.
