Water has always been crucial for agriculture from the beginning. Plants won’t thrive in the absence of water in areas where the primary water source is rainfall or there’s a low supply of water. So farmers are one of the most crucial contributors in our society because they are food providers. However, food is not the only thing being farmed; energy is farmed as well.

Farmers generate renewable energy from the sun, wind, and biomass. For instance, solar energy can power a solar water pump for irrigation. Renewable energy is essential in today’s world because it’s one way to simultaneously generate electricity while protecting the environment.

Solar Energy in Farming

Solar energy is the most organic energy a farmer can generate. On a farm, there are numerous buildings whose roofs have direct exposure to the sun. Tree branches do not hinder their access. This makes them the perfect spot to install solar panels. Nowadays, the utilization of solar energy in farming is gaining more traction and acceptance.

The farmer can utilize solar power to generate energy using solar water pumps if there aren’t frequent rainfalls in the area. These days solar-powered products are increasing in the market. For instance, solar water pumps use solar energy to pump water in the farm. The greater the sunlight, the greater the supply of water to the plants. The farmer can also utilize solar energy in agro-processing structures (in the case of large-scale farming).

The Workings of Solar Irrigation

A solar irrigation system is a combination of two things:

  • Photovoltaic cells
  • Water pumps

While the PV cells are responsible for generating electricity from the rays of the sun, the pumps contain a motor that is responsible for using that electricity to suck and transport water to the needed areas on the farm. Its functionality is similar to conventional water pumps powered by generators or electricity from the power grid. However, solar pumps have the edge over traditional pumps.

Solar Irrigation Pump on Farm

Firstly, electricity is inconsistent in remote areas not covered by the power grid or in developing/underdeveloped countries. In such cases, a traditional pump will be almost useless because it can’t function without electricity. This isn’t an issue for solar pumps. As long as the location of your farm has exposure to sunlight, solar pumps will function. So solar irrigation is a helpful solution to water supply in arid areas.

When it comes to diesel-powered pumps, their functionality depends on the availability of diesel. Apart from that, the excess expenses that will incur using a diesel generator are not eco-friendly. When it comes to purchasing costs, diesel pumps cost less than solar pumps, but when you consider operating and maintenance costs into the mix, the diesel pumps will burn a deeper hole in your pocket.

Diesel pumps involve frequent supplies of diesel, servicing, and repairs costs. On the other hand, solar pumps may cost much at first, but you’ll virtually spend next to nothing on operating costs. You need periodic maintenance, and your fuel (the sun) is free and limitless. The only constraint to solar irrigation is rainy or cloudy weather.

In the long run, solar pumps are better options for water management in agriculture.
