Technical Details.
*************
Motor is planned to run at 90% efficiency rather than 100% to save cost as 10% doesn't make difference practically.

Plant Components
*************
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.
Both the stings are connected in parallel to generate 16 amps current, which generates 9120 Watt onload energy.
Mounting structure is locally fabricated by the local steel worker as per our design standards.

Controller components
********************
Surge arrestor is used to protect the system from lightning effects
DC MCB is used as a circuit breaker
VFD is used to convert DC power to 3 phase AC with variable frequency. VFD is tuned as per the motor specifications.
AC MCB is used as circuit breaker on motor side.
Online reactor is used to reduce the inductance current as the motor distance is longer from the control center.

Motor specifications
**************
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.

Water discharge
************
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

Failover connectivity
***************
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.

Future expansion
************
Planning to distribute the excess power to the nearby village for lighting purpose. We are working on the suitable devices and our research is in progress
