An irrigation unit ( 20 ) for irrigating an area ( 12 ) with a fluid ( 19 ) from a fluid source ( 18 ) includes a housing ( 200 ), a nozzle ( 220 ), an electronic component ( 221 ), and a power generator ( 230 ). The nozzle ( 220 ) is directly or indirectly secured to the housing ( 200 ) and the nozzle ( 220 ) is in fluid communication with the fluid source ( 18 ) so that fluid ( 19 ) from the fluid source ( 18 ) is transferred to the nozzle ( 220 ). The electronic component ( 221 ) is directly or indirectly secured to the housing ( 200 ). The power generator ( 230 ) generates electrical energy that is transferred to the electronic component ( 221 ). The power generator ( 230 ) directly transfers at least a portion of the electrical energy to the electronic component ( 221 ) of the irrigation unit ( 20 ). The electronic component ( 221 ) can be a power storage unit ( 222 ) for storing electrical energy for use by the irrigation unit ( 20 ).
