It is a fact that all of us are dependent on water for survival and the best way to get unlimited supply at home is through a water pump. But a solar water pump is a better idea as it makes use of sunlight and not electricity to draw water for you. If you are someone who is interested in installing a small scaled or a large scaled solar water pump at home or office, then this article will prove useful. It will help you learn the steps or procedure to follow for installing solar water pump. So read on to find out.

STEP 1: Set up the solar panel stand

A Solar panel does the work of supporting the pump and consists of I beams and C Channels.  Before you start building this metal framework, you must find out the appropriate solar angle. Solar angle is the optimum angle at which the panels or pump will receive the maximum sunlight.  Angle the panels towards the sun and to find it you can use an online calculator.

Also you need to paint all the beams and channels with a layer of anti rust or anti corrosion paint so as to avoid them from getting corroded in the future.  Build the metal framework after this.

STEP 2: I-Beam placement and foundation

Follow the given steps to place the I Beam and set up the foundation:

  • Firstly, dig a hole of dimensions 2 ft x 2ft x 2ft in the ground followed by adding concrete into it.
  • Place the I beam into the hole in such a way that it is at a right angle to the ground.
  •  Fill the hole with concrete after ensuring 2 ft of beam is in the ground.
  • Place another beam at a distance of 24.46 ft from the first one following the same procedure.

STEP 3:Add lower C Channel

Now you need to place a lower C Channel by following the given steps:

  • Place the C Channel parallel to the ground and ensure this by using a level bottle
  • Now bolt each of the ends of the C Channel to the I Beams. Use stainless steel bolts and nuts for this.

STEP 4: Add other beams and channels

In this step, you need to add the remaining beams and channels following the given steps:;

  • Add 2-7 ft I beams on top of 2-11 ft I beams. Attach a 24.46 ft C-Channel to the beams.
  • Now in the two remaining corners, place and fit the 2-11 ft I beams perpendicular to the ground.
  • Like before, add the remaining channels to these beams.
  • You also need to add the inclined channel which has dimensions 5×20.84 ft

STEP 5: Adding solar panels

Once all the beams and channels are fixed, you need to add the solar panels.  You need to add 21 of these panels.  The panels must have the given specifications:

  • Power-280W
  • Voltage at Pmax-35 V
  • Lenght X Breadth X Height(mm)-1960x990x42

For fixing the panels, you first need to bolt them to the C-Channels. The distance between them should be 0.25 ft from each side. Connect the solar panels by first opening the solar panel connector box and then using a multimeter to find the polarity of the solar panel.  Connect 7 solar panels in series to form one string. 3 such strings will be thus formed.

STEP 6: Make the electrical connections

In order to get output out of the framework, you need to make the appropriate electrical connections.  Do this with the help of an electrician or refer to the pump manual for the same.  Remember that the solar pump system controller is the brain of this installation process and its working.  This controller regulates the current supplied to the pump from the panels.

STEP 7: Solar water pump

The solar water pump uses the power supplied from the panel array to pump water from the source.  It comes with 3 wires for each phase and one wire for ground. Make sure you choose a good pump depending upon your requirement.
