I'm intending to use sockets and plugs near these loads rather than hardwiring all the way, so that in the future it will be easy to, say, run a welder over by the pond instead of the pump.
No, that statement is most likely incorrect. Their 260W rating is determined in a controlled temperature test chamber under artificial sunlight scaled at 1000W/square meter. Voltage goes down with increasing heat, and panels sitting in the noon sun will NOT be at the 25oC test temperature. And, the real sun can't be counted on to be producing 1000W/M. For people that work in the real-world with solar, derating the panels to 80% is typical. Less than perpendicular orientation, and it's even less. I'd say if at any point in the day if the panels passed the 400W mark, I'd say that was outstanding.
