Abstract

This research proposes the design of a climate-adaptive photovoltaic pumping and irrigation system (PV-PIS) for a 7-hectare sugarcane plot in Chimbote, Ancash, aiming to improve water and energy efficiency within the Peruvian agricultural context. The study addresses the sector’s high-water demand, dependence on fossil fuels, and increasing climate uncertainty. The methodology followed an applied and quantitative approach with a descriptive-propositional design. Historical meteorological data from NASA Power and SENAMHI were used to determine the crop’s water requirement, estimated at 370.3 m³ per day, as well as the optimal solar resource availability. Based on these parameters, a 7.06 kWp photovoltaic system composed of thirteen 575 W monocrystalline panels was dimensioned, managed by an 8 kW hybrid inverter and integrated with an automation system using a Siemens S7-1200 PLC and environmental sensors. Technical validation was performed through SISIFO software simulation, yielding an estimated annual energy generation of 12,217 kWh. The economic analysis determined an initial investment of S/. 56,586.09, a levelized cost of energy (LCOE) of S/. 0.781/kWh, a positive Net Present Value (NPV) of S/. 7,955.03, and an Internal Rate of Return (IRR) of 12.00%, with a payback period of 7.46 years. The results confirm that the proposal is technically and financially viable, representing a sustainable alternative to conventional irrigation systems
