This paper presents the dimensioning of an irrigation system applied to a lemon crop. Making use of solar power, it satisfied the Potential Evapotranspiration (PET) values of 4.31 mm/day and Consumptive Use (CU) of 1.85 mm/ha/day, whose experimental matrix is composed by three furrows of 57 trees with a requirement of 64.91 liters/tree/day, using dripping irrigation systems with a water discharge of 4 liters/hour. The study demonstrates, at a very significant level, that humidity concentrates at a depth of 15 cm. which is influenced by the sandy physical characteristics of the soil. Thus, for the irrigation water requirement, it is dimensioned a solar system obtaining a setting of 10 panels in series and 2 others in parallel, for a total of 20 as a whole, a capacity inverter to power a 2HP pump and a house with an average consumption of 1.5 kWp. The global efficiency of the system was registered in the range of 10 and 14%, and the maximum output power of the photovoltaic system was reached between the 10:00 and 14:00 hours with an 84% of the total capacity installed (5.2 kWp).

Keywords : irrigation system; solar power; global efficiency; evapotranspiration; lemon.
