HP Solar Water Pump design and implementation
is designed in a most economic way at a cost of INR 50,000 per HP.
The overall cost will be around INR 5,00,000/- where as if you buy
from market you need to shellout close to INR 10,00,000.
Following is the high level design specification
Mono Crystalline 250 W panels - 38 Numbers
19 in series sting and another 19 in series sting, which generates
570 V onload voltage and 8 amps onload current.
Connect both the series stings in parallel, which generates 16 amps
current. The overall onload energy will be around 9120 Watt.
Mounting structure is locally fabricated by the local steel worker
as per our design standards.
Surge arrestor is used to protect the system from lightning effects
DC MCB is used as a circuit breaker between panels and VFD
VFD is used to convert DC power to 3 phase AC with variable frequency.
Tune VFD as per the motor specifications.
AC MCB is used as circuit breaker between VFD and Motor.
Online reactor is used to suppress the inductance current spikes as
the motor distance is longer from the control center.
CRI 10 HP 3 phase AC submersible motor is installed at 300 ft deep
in a borewell and from control center the overall distance is around
400 feet. Its maximum specifications are 440V/20Amps/50HZ. This requires
7500 Watts energy where as the solar plant is designed for 9500 Watts
and the excess power is considered for energy losses and distribution
to other power devices.
Motor starts at 7:30 Am with 30 HZ frequency and runs till 6PM. Below
are the frequency variations with corresponding water output on a
clear sunny day.
7:30 AM - 30 HZ - around 2 inch water
8:30 AM - 40 HZ - around 3 inch water
11:00 AM - 48 HZ - more than 3 inch water
3:00 PM - 45 HZ - 3 inch water
5:00 PM - 38 HZ
6:00 PM - 30 HZ
Designed to switch between Grid AC power and Solar power sources.
Designed to connect to two motors 7.5 HP and 10 HP, any one can be
used at a time.
