Actually, I think the heat of vaporisation is more than the energy to heat the water to boiling: 2.26 MJ/kg, which takes us to ~4TJ/day.
The 1000W solar radiation is also for the sun directly overhead without clouds, which obviously can't happen for 12 hours a day. I've found a source saying Bangkok gets something like 20MJ/m^2/day, and higher latitudes presumably have less. With those figures we're at 200000m^2 of evaporation area, and it's still optimistic (what about rain?).
