Access to water in areas of high marginalization is undoubtedly one of the main problems to be solved. The objective of this study was to design two photovoltaic systems with solar pumps, the first to establish a planting area for vegetables, and the second with the purpose of bringing water for livestock consumption. The work was developed during the years 2015 and 2017 in the towns of Vicente Guerrero and Lázaro Cárdenas, municipalities of San Juan de Guadalupe Victoria, Durango, Mexico. In the first municipality there is a pond with a capacity of 50,000 cubic meters and in the second, there is a well. According to the maximum demands of crops 6.6 mm d-1, a pump was designed with a capacity of 221.6 m3 d-1 and a total dynamic load of 25 m with 20 solar panels. In the second case, it consists of moving the water at a distance of 4.5 km and 62 m against the slope, for which a pump with a capacity of 30 m3 d-1 and a total dynamic load of 93.3 m was designed with eight solar panels.
