Solar Pump

India’s agriculture sector is heavily dependent on monsoons for natural irrigation. Pumps are used as an artificial means to provide water for irrigation. Farmers rely on grid electricity or diesel gen-sets to run the pump, which leads to huge delays and economic stress. Hence, for our farmers, an effective irrigation system such as the Solar Water Pump is a great boon. It increases their crop yield by ensuring a reliable and perennial supply of water to their fields.

A solar water pump is an innovative technology water lifting system that is powered by solar energy. It is also known as Solar Pumping System, Solar Submersible Pump, and Solar Pump. This system typically consists of a  solar panel, solar inverter, controller, and sometimes a solar battery. These pumps are more economical since they don’t need grid electricity and reduce carbon footprints too.

A solar water pump is an application of photovoltaic technology which converts solar energy into electricity to run the pumping system thereby, replacing erratic grid supply and pollution-causing diesel-powered versions. The solar water pump is powered by solar modules that help draw surface or groundwater out for irrigation.

These pumps help reduce farmers’ dependency on expensive fuels and their maintenance costs as opposed to conventional irrigation systems. By switching to Solar Water Pumps, farmers can have access to a highly-efficient power supply that can be used throughout the day to provide a consistent water supply.

How DOES A Solar Pump Work?

The working of the solar pump starts with the solar panel. Solar panels are made up of a bunch of small silicon solar cells that absorb the sunlight and convert it into DC electricity, which powers the pump. The solar pump directly connects with the solar panel through an MPPT solar pump controller. So whenever sunlight hits the solar panel and you turn the pump on, it starts to lift the water.

In case you are using an AC water pump, then the generated electricity will pass through the solar inverter. Therefore, you will have to install a solar inverter with your solar pump. The inverter will convert the DC electricity into AC electricity and then transfer it to the pump.

Solar Water Pump Technologies

There are three technologies to power your solar surface water pump (AC & DC) and solar submersible water pump (AC & DC). A brief description of these technologies is mentioned below.

On-Grid Solar Pump

In an on-grid solar system, your water pump will be powered by a solar panel. In case the solar panel is generating more power than the water pump’s consumption, then the excess power will automatically be exported to the grid via net metering and the government will adjust it in your next electricity bill.

Hybrid Solar Pump

In a hybrid solar pump, there are three power options to run the solar pump. The first is solar power, the second is the grid electricity and the third is a solar battery. In day time your water pump is powered by solar electricity, at night it is powered by the grid and when both (solar power and grid) are not available then it will be powered by a battery.

Solar Pump VFD Drive

VFD drives are a modern solution to the problems of farmers. The solar pump VFD drive converts your existing water pump into a solar pump. This technology is becoming famous day by day. There is a shortage of electricity in the rural area and through the VFD drive farmers can operate their pumps even when there is no grid.
