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

I didn't compensate with brackets for the slope from the curve of the rooftop, leaving that slight angle for drainage.
This is exactly how it should be done. With few degrees slope for drainage.
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.
When it rains, the output drops 5-7 times. My 500W flat array then can barely harvest enough to run the fridge and lights.
