Sewing Machine
Panel – Charge controller – DC Motor
Panel= 100 watt
Batter= 12V , 40AH


  • PMDCM= Permant Magnet DC Motor 
  • Charge Controller Type= PWM (Pluse With Modulation)

Revolution Per Minute

Increasing no of pole = Increasing RPM

Solar Pumping

300 watt = 72 cell

1 cell =160mm*160mm

panel connection in series

flow of water= 23.65


Drive Efficiency = Pump Sharp Power/Motor Power

Efficiency Output Pump-

Pump Efficiency= Efficiency output pump /Pump sharp power

N(overall) = n(pump) * n (drive)

Solar powered water pumps can deliver drinking water as well as water for livestock or irrigation purposes. Solar water pumps may be especially useful in small scale or community based irrigation, as large scale irrigation requires large volume of water volumes of water that in turn require a large solar PV array.

A photovaltaic solar powered pump system has three parts

1 Solar panels

2 The Controller (using MPPT)

3 The Pump

Charge Controller– In solar pumping using charge controller. Charge controller having two types 1. Pulse with modulation

2. Maximum power point Tracking

In these system using MPPT ( Maximum Power Point Tracking) charge controller. MPPT charge controller using large scale system. for example – Solar pump, PWM( Pulse With Modulation) charge controller using small scale system. for example – Sewing machine, Milky machine

The Size of the PV- system is directly dependent on the size of the pump, the amount of the water that is required and solar irradiance available.

Inverter in 5 KVA

we use mppt charge controller .


battery capacity ; 96v and 150Ah

1 panel = 250w we use 10 panels and 5-5 panel are connected in series & both panels are connected in parallel .

solar pv system.

5 panel voltage : 36*5=180v

power : 250*5= 1250w

current = 6.940

parallel current : 13.88
