Solar Pumps


A solar PV water pumping system – commonly known as a solar pump – draws power from solar cell / modules to operate a motor pump set. Solar power pumps use specially developed and energy efficient motor pump sets to achieve higher discharge which off sets the high initial cost. A solar PV water pumping system consists of a number of solar PV modules connected in series – parallel combination to generate sufficient power to operate a motor pump. The system does not have any storage battery since power generated is used directly then and there. The pumping system can draw water from the open well / bore well or stream / pond or canal.
Types of Solar Power pumps: SPV water pumping system may be of any one of the following types of motor pump sets 1.In-built Controller Brushless Solar Pump 2.Submersible Solar Pump 3.Floating motor pump

In-built Controller Brushless Solar Pump

Solar pumps are specially designed pumps which run at low/
variable frequency and powered by solar photovoltaic modules. There are
two basic types of solar pumps DC and AC pumps. In DC pumps brushless
DC motor is used whereas in AC pumps specially designed AC motor which
is compatible to run on Solar power is used. These pumps may be either
surface or submersible pumps. Generally, solar powered surface pumps
up to 2.2 kW (3 hp) and submersible type up to 75 kW (100 hp) are available.
Electronic controller is used between solar PV modules and pump which
controls the electrical parameters of the pump. PV modules are configured
in series and parallel connection to suit the electrical requirement of pump.
These PV modules are installed on a metal structure. The structure
can be either fixed type or tracking type. Tracking structure follows the Sun
path and gives 20-25 % more water output than the fixed structure.

A 3 HP solar water pump is latest technology water pump that don’t rely on grid electricity to operate or power the pump. Instead it use solar energy, generated by 3kW solar panels to lift the water. There are many advance safety features in it like dry run, reverse polarity, low voltage, etc.

Solar powered water pumps have many benefits over their traditional counterparts. They require no outside power sources and can be used in areas where there is no access to electricity. Furthermore, they comes with 5 years complete warranty.

There are three power options available to operate a solar water pump i.e. solar power, solar battery, and grid electricity. In case, solar power and battery backup is not available, than a 3HP (horse power) solar water pump can be operated on regular grid electricity. A solar pump extracts maximum solar energy and reduces your electricity bills up to zero rupees.

There are two types and 3 technologies to operate a solar water pump through one of which, you can also run your existing water pump on solar power. So it’s worth spending 10 minutes reading this information and selecting the best that meets all your requirements.
