The trade winds do not follow the coasts, they go from east to west in the tropical zones.

Re: Wind turbine?
To make 1 kW of heat with a wind turbine, you can "simply" run a pump that delivers 1 liter second under 10 bar, or 10 liter seconds under 1 bar, temperature resistant, inside an insulated tank . I don't know how to calculate at what rpm the ...

Re: Thermal buffer: avoid surface evaporation of hot water with oil or other blocking product?
It was just in case there was really no air entering the circuit of the panels. This would not be normal operation for a self-draining system.
I think you have an air inlet in the circuit, ideally air from the buffer.

6 meters is approximately the maximum pumping (or siphoning) height on the suction side. Above the depression is too strong and the water evaporates.
