The Casa Maria Soup Kitchen won Technicians for Sustainability’s solar grant for 2011 and received a 3.87 kW solar electric (photovoltaic) system.  The system saves the soup kitchen over $70 a month which allows them to reallocate those funds towards offering more services and providing food to more people. The organization was chosen to receive the TFS 2011 solar grant because of their wonderful involvement and unfailing assistance in the Tucson community.  At their Free Kitchen, Casa Maria volunteers serve lunch to 600 single persons, many of whom are homeless and they provide a family food bag to more than 200 families who are on the edge of poverty.  They also have a free Medical Mobile Clinic twice every week, a program for Vaccines for Cats and Dogs, and offer American Citizenship Lessons in Spanish and leadership and Community Organizer Training also in Spanish.

According to Casa Maria volunteer, Jerry Gill, "This solar system gives us an opportunity to extend our commitment to serving the poor with justice and in harmony with the earth. We already participate in recycling day old food donated by various food stores and restaurants, as well as used clothing from different private donors. We also grow some food of our own. Now, not only will we be able to save a considerable sum of money, but we will lessen our carbon footprint at the same time".
