WHY SOLAR POWERED PUMP?
RURAL INDIA LOOKS BEYOND THE GRID OFF GRID
RENEWABLE

• 50 of energy produced in the world is used in
  operating various kind of Pumps.
• 50 of any SOLAR PROJECT Cost are invested in
  battery back-up and SPP run during day time so no
  investment in back-up.
• Independence from Grid as Grid electricity are
  not feasible at remote location.
• Also, the use of solar energy
• eliminates noise, emissions and fuel spills,
  contributing in this way to the conservation of
  the environment.
• Early pay back period.
• Long Life.
• Reliable power supply source
• More saving due to low maintenance
• Hassle Free of logistics
• Demand for Bigger Pump
• The Solar Pump extracts water over a long time
  period during the day so the low yielding
  borehole has time to refill.

• How much water does it pump?
• The daily water output of a solar pump depends on
  four factors
• How much solar energy is available?
• What is the power of the solar panels that are
  used to change the solar energy into useful
  electricity?
• What is the total vertical distance that the
  water is pumped, measured from the water level in
  the borehole to the level of the water in the
  reservoir (total head)?
• How efficient the system is?

Solar photovoltaic panels-

•  SPV is a power system used to supply usable
  solar power by means of PHOTOVOLTAIC'S. It
  employs solar panels composed of number of solar
  cells to supply usable power.
• Photovoltaic (PV) is a method of
• converting solar energy into direct
• current electricity using
• semiconducting materials
• (Mono/Multi crystalline silicon cells).
• The available power harnessed from Sun is 12-25
  depending on the type of cell type.

Solar Water Pump Major Elements-

• DC Pump

• AC Conventional Pump

• DC Pump
• Standard capacity 1-3Hp
• External protection required
• Lower operating voltage
• Ease in installation, Simple Operation.
• Very efficient for low budgeted project and
  portable solution.

• MPPT Controller
• AC Pump
• Standard capacity 2-15Hp
• Soft protection available from Drive
• High Voltage system hence the losses.
• Motor to controller distance needs to be
  maintained to avoid spike voltage
• Longer Life and modular

• Structures to mount
• Solar panels
• protection circuit (MCB, Surge Protector and
  Earth, Dry Run protection unit, Etc)
• Tank to Store Water(Optional Best for Household
  works Drip Irrigation)
• Automatic On/Off system.

Supreme Offers AC and DC Pump Solutions

• DC Pump are efficient and portable with respect
  to the power required are available from 1-3 Hp
  which suitable for Drinking, house hold works,
  Small Farm Irrigation.
• DC Surface pump

• AC Pump are efficient solution can be installed
  new or retrofit an existing pump with solar power
  AC pump are available at higher Hp varying from
  2-15 Hp most suitable fro irrigation purpose.
• Surface Pump for flood irrigation.
• Solar-Grid Crossover Switch

System Description

• The Pumping solution is designed to offer the
  rural areas, water to use for domestic
  application. 1 setup will use 700-800 Wp of Solar
  power to run 1 Hp of submersible pump at depth of
  20-70 mtr. It will discharge 5000-8000 LPD. It
  will also have automatic on/off mechanism to
  avoid water wastage once the tank is filled.
• The system is a retrofit solution to the
  existing hand pump already installed. Hence it
  will be a Dual pumping system where people can
  have water through hand pump at the absence of
  solar energy.

Solar Powered Curve with MPPT Range at radiation
variation for AC Pump

• Supreme offers MPPT controlled Solar Pump
  controller which keeps on tracking the max power
  and available from the solar panels and drives
  the motor to run at max power available.
• The Algorithm also helps pump to halt when there
  is insufficient power available.
• It also takes care of Stall frequency.
• High processing algorithm also helps is to reduce
  down the power consumption when there is sudden
  power drop.
