This study presents a crop-focused approach to understanding electricity use in drip-irrigated farming systems
supported by photovoltaic pumping. By linking crop water needs with irrigation efficiency, hydraulic conditions, and
pump operation, the framework captures energy demand at both plant and system levels. The findings show that energy
requirements vary notably across crop types, mainly due to differences in biological water demand and cultivation patterns.
When applied to a mixed-crop irrigation layout, the approach confirms that total energy demand is largely shaped by crop
composition and irrigated area. Solar-based pumping was found to be technically capable of meeting irrigation energy
needs, while drip irrigation demonstrated clear energy-saving advantages over traditional surface methods.
