Course: 22.527 Solar Systems Engineering
Semester: Spring 2009
Instructor: John Duffy
Partner:Tohono O’odham reservation
We are working with a tribal college on the Tohono O’odham reservation near Tucson, AZ. The tribal college (TOCC, http://www.tocc.cc.az.us/about_ton.htm ) is constructing modular bathrooms for the elderly and for families in remote regions of the reservation. Many of the families on the reservation have no electricity or running water, and the folks use outhouses. It is estimated that there are 10,000 families on reservations in AZ that do not have electricity from the grid (Alternative Energy Retailer, Oct. 2007, p. 14). The students at the college are learning plumbing, carpentry, and electrician skills. We have formed a partnership in which UML would do the solar engineering and TOCC the construction. Initial sizing of the PV system have been made by Vivian Crespo and design of a variable-slope support structure by a capstone design group Spring 2008. What is needed is a detailed system design with all the components for a load with an evaporative cooler.
