Solar Water Pumping System Design and Installation for Laguna, Peru

Course: 22.504 – Energy Engineering Workshop
Semester: Spring 2007
Instructor: John Duffy
Partner: Village Empowerment Peru Project – Village of Laguna

Brief Description:

Two students chose to design, model and test a solar water pumping system for remote regions of Peru. Their work focused on designing a photovoltaic pumping system that would feasibly deliver water to ten households in the community of Laguna, Peru. The design was to deliver at least 400 liters of water per day on average and provide storage of 1,100 liters. The system was designed to include solar photovoltaic modules, a controller, wiring, support structures, enclosures, a pump, pipes, water tank, gauges and valves. The students also opted to assess the reliability of the pump and system controls for pressure and temperature.

The students also opted to assess the reliability of the pump and system controls for pressure and temperature.

The purpose of this student project is to contribute to sustainability of pump systems and decrease need for pump replacements in the Peru project. Students developed mathematical models of the pump requirements, assessed piping and wiring needs, and simulated pump voltage and pressures. Students concluded that the principles learned in their Solar Energy Fundamentals, Solar Systems Engineering, and this Energy Engineering Design Workshops provided a foundation to apply these principles to design and model this solar water pumping system for Laguna, Peru.

Community needs met:

  • The water pumping system was installed by the students in Laguna, Ancash, Peru in June 2007.
