Solar Photovoltaic (PV) pump operated drip irrigation system has been designed and
developed for growing orchards in arid region considering different design parameters like
pumps size, water requirements, the diurnal variation in the pressure of the pump due to change
in irradiance and pressure compensation in the drippers. The system comprising a PV pump
with 900 Wp PV array and 800 W dc motor-pump mono-block, micro filter, main and submains
and three open-able low-pressure compensating drippers on each plant was field tested.
The emission uniformity was observed to be 92–94% with discharge of 3.8 l/h in the pressure
range of 70–100 kPa provided by the pump and thus the system could irrigate some 1 ha area
within 2 h. Based on the performance of the PV pump and the drip system, it was inferred
that about 5 ha area of orchard could be covered. The projected benefit–cost ratio for growing
pomegranate orchards with such a system was evaluated to be above 2 even with the costly
PV pump and therefore the system was considered to be an appropriate technology for the
development of arid region.
