Direct Coupled Irrigation System

In a direct coupled PV system, the PV array is connected directly to the load. Therefore, the load, pump, can operate only whenever there is solar radiation, so such a system has very limited applications. A typical application of this type of system is for water pumping, i.e., the system operates as long as sunshine is available, and instead of storing electrical energy, water is usually stored. As the irrigation process mainly occurs in sunny hours, this solution is feasible for rural areas, with a hard place topology.
