Probably all over. There's tons of dealers. I just linked ones from a post I had saved. Personally, I wouldn't worry about bifacial panels. They cost more then the extra power you would get under ideal setup, assuming you don't get real complicated with adding reflectors.
I would just use single faced panels. Set them on my roof facing south and angled at 30 degrees, and let them do their thing. Bonus they block light from the roof and keep it cooler, reducing cooling costs in the summer.
That being said, one could get real complex with bifacial panels. They actually work very well by placing them vertical facing south/north. One could put them vertical on their roof, given they have a very sturdy structural setup. Then, paint their roof white. This has the added benefit of keeping the roof cooler in the summer.

I would use this costing or a similar one for the roof. Guy in the video shows it reduced roof heat by 30-35 Celsius, which is insane. So the roof itself becomes a reflector and would boost panel efficiency.

This video does a really good breakdown of the different panel formations and how they compare.
