RURAL INDIA LOOKS BEYOND THE GRID – OFF GRID RENEWABLE

Solar Photovoltaic Water Pump

—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.

Comparison Between Solar & Diesel powered Pump

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. SPV is a power system  used to supply usable solar  power by means of PHOTOVOLTAIC’S.

Architecture for Convential & DC Pump

Solar Water Pump Major Elements

DC 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.

AC Conventional Pump

  • 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

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 AC Pump

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

—Levicon 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.

Levicon Offers complete customized solution for AC Pump

—Levicon assist Client to chose right pump according to the clients requirement depending on the Water Head, Discharge Required, Selection of pump stages and Pipe dia to get optimized energy efficient solution.

—We assist one selecting the right Solar panels according to the MPPT range required for the controller.

—Multiple alarming features makes the system troubleshooting very handy and ease to resolve via field technician.

Levicon had installed upto 5 Hp Submersible & Surface Solar Pump Controller In Maharashtra.
