Solar Pumping

300 watt = 72 cell

1 cell =160mm*160mm

panel connection in series

flow of water= 23.65

Drive

Drive Efficiency = Pump Sharp Power/Motor Power

Pump Efficiency= Efficiency output pump /Pump sharp power

Efficiency Output Pump-

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

1. 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

3. Panel

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.
