A Guide to Solar Powered Linear Move Irrigation Systems and Their Benefits
What Exactly is a Linear Move Irrigation System?
A linear move irrigation system is a type of mechanized irrigation where water is delivered to crops in a straight line. Unlike center pivot systems that rotate around a central point, linear move systems travel in a straight path across the field. This makes them a good fit for rectangular or square-shaped fields, as they ensure even water distribution.
This system is made up of a series of pipe spans, often held up by wheeled towers. Water is pumped through these pipes and distributed through sprinklers or emitters that are attached to the spans. The entire system moves in a straight line, powered by motors or hydraulic systems.
Solar Energy as a Power Source
Photovoltaic (PV) panels capture solar energy and turn it into electricity. This electricity can then be used to run the motors and pumps of a linear move irrigation system. Solar-powered systems are especially useful in remote areas where there is little or no access to the electrical grid.
Moreover, the use of solar power lowers reliance on fossil fuels, making the system more sustainable and better for the environment. The initial cost of solar panels can be high, but the long-term savings on energy bills often make up for the cost.
