Solar System Manufacturers in Mumbai

     A Solar Pump uses power derived from Sunlight that is converted into electrical power by solar photo voltaic (SPV) Modules. These modules give higher power output in the afternoon and lower output in the mornings and evenings depending on the sun’s position. As a result, a solar pump works on varying power input and gives varying water output at a given pump head. Conversely, an electric or diesel-powered pumpset work on constant power input giving a constant water output at a given head.

The most important parameters to select a solar pump are:

  • Quantity of water needed or available at source
  • Application head
  • Location - The location is important because solar energy varies from area to area, and sizing of solar panels depends on the solar energy in that area.


Components of a Typical Solar Pumping System

A Solar Photovoltaic (SPV) Water pumping system consists of:

1. PV array:

  • Capacity in the range of 200 Watt to 5 KWp.
  • Mounted on a suitable structure with a provision of tracking the sun motor pump set (Surface or Submersible):
  • A.C Induction Motor pump set with a suitable Inverter

2. Electronics :

  • Maximum Power Point Tracker (MPPT)
  • Controls / Protections

3. Interconnecting Cables and “On-Off” Switch:

  • Foundation set (Consisting of foundation bolts and mounting structure for solar and panel controller
  • Earthing kit

4. Motors For The Solar Pump Sets :

  • Up To 2 HP: 120V, 3 Phase AC., 50 Hz Induction motors as standard, working with varying frequencies to the sun’s intensity.
  • From 3 to 7.5 HP: 415V, 3 Phase A.C, 50 Hz Induction motors as standard

(Customized Pumps, With Voltages other than 415 V and frequencies varying up to 60 Hz,can also be supplied against special customers requirements).


Advantages of PEW Solar Pump Controller:

     PEW Solar pumps come with a triple mode maximum power point tracking (MPPT) feature.under this, the pump, motor and solar modules are all made to run in the most optimum efficiency zone automatically. With variation is sunintensity ,as motor tends to get underloaded , an electronic correction is applied to maximisation of motor effciency. Thus , effciency of solar panels, Pump, and motor are maximized.

     This is facilitated by a solar  pump controller (designed as per IEC 61683) and tested by NABL / BIS accreadited laboratory as specified by mainistry of new and renewable enegy (MNRE), Govt of india , Under jawarharlal Nehru national solar mission (JNNSM)

The Controller has following safety features incorporated in them:-

  • Sensor-less dry run protection
  • Under voltage and over voltage protection
  • Reverse polarity protection
  • Soft start for the ac induction motors


Principal Of Operation Of Solar Pump Controller:

     Solar power is converted into varying DC power by solar PV modules, Depending on Changing sun during the day, This DC power is converted into 3- Phase AC power whitch drives the AC induction motor pump set directly. As a result, battery charger are both eliminated

  • Dual Mode Unit This option enables the user to run the same pump with either solar power or grid power, whichever is available.
  • Battery Charger cum booster unitThis enables diverting low solar power input , produced by solar modules in the morning and evening (which make it difficult to run a pump), to charge appropriately sized batteries, whitch can them be uses to power CFLs, Fans, TVs, the night
  • Flexible output unit ( 3 Ph/ 1 PH. AC Output  - if the pump is not required to be run during some part of daylight hours, the user can turn the rotary switch on the single phase AC position and operate a few CFLs, fans, TVs, Computers etc. (This unique optional feature is provided for smaller pumps upto 2hp)



  • No Requirement of Conventional grid electricity
  • Highly dependable and robust
  • Easy to carry, operate and maintain as it has a lightweightbody
  • Eco – friendly and no fuel costs
  • Uses free solar energy low maintenance costs



Provide Water supply to-

  • Villages, School, hospital, Homes etc.
  • Tribal settlements and other far flung areas
  • Rural schemes
  • Resorts, hotels, and farm houses
  • Animal farms and poultries
  • Housing Societies and apartments – from underground water tank to overhead reservoirs
  • Farms, fields and greenhouse
  • Corporate / industrial parks and gardems (auto watering manual intervention)
  • Micro- irrigation
