Solar Mamas is the affectionate name given to women from different countries who have had hands-on training as technicians on the solar programme at the Barefoot College based in India. These women, with little or no formal education or literacy, usually between 35 and 50 years old, with no young children, and coming from often impoverished rural areas, go on to assemble, install, repair and maintain solar panels and equipment in their previously non-electrified villages. The women gain a sustainable income by doing this and have a new role in their communities beyond that of wife and mother, having given them the benefits of a safe, sustainable source of lighting for work, education and family life.
