Exemplary embodiments of the present invention are directed towards a solar water pump. 
The solar water pump includes an organic fluid pump connected to a receiver tank of a condenser to pump and pressurise a liquefied organic fluid into the organic fluid tank placed closer to a header of an evacuated tube collector to store the pressurised liquefied organic fluid, a first pressure and temperature switch connected to the organic fluid tank to sense the pressure and temperature of the organic fluid vapour and to operate a first solenoid valve placed between the organic fluid tank and a power generator for supplying the organic fluid vapour to the power generator and a second pressure switch connected to the organic fluid tank controls the power input to the organic fluid pump through a circuit breaker; a second solenoid valve, connected between the condenser chamber and the mechanical pump, prevents the flow of motive fluid from the condenser chamber to the mechanical pump when the mechanical pump is not in operation.
