So the things to consider with these:
They are 120 VOC, but they daisy chain together in parallel (up to 8 I think) with built in cables on both ends. So no need for combiners, or branch connectors, or extra PV wires. Pretty neat.
They are heavy as hell.
They don't get close to putting out the rated wattage. They are designed to have a round production curve, rather than a peak. I think they end up producing the same as a comparable wattage standard panel throughout the day.
They are designed to lay flat, and be self ballast. They need to be installed over a reflective surface (white, or shiny, etc) for best results.
