The handful of women are the latest batch of grandmothers from across the world who participated in a certificate programme that began in September, 2013, to learn the knowhow for electrifying their villages using solar technology.
The programme is part of the solar engineering programme conducted by the government's India Technical Economic Cooperation (ITEC) which in 2008 adopted the Barefoot College in Rajasthan's remote Tilonia village as a training centre.
"I am happy to have participated in the training course at Tilonia. Now I'm anxious to go back home and teach everybody about solar energy," said Anna Paulo, a grandmother from Brazil.
"Anna is one of the four women we chose from Brazil for the programme... It was at a time when a rape case received wide publicity and the women chose not to come. But this gutsy woman came," said Sanjit 'Bunker' Roy, founder of Barefoot College.
The ambassador of Brazil, who helped translate Paulo's address, said, "If you can replicate this experience with other people from my country, I will be glad."
"At first, I was scared to come to India because I did not know English or Hindi but, suddenly, I found myself in class," said Rashmi, who donned a traditional off-white Indian salwar kameez for the occasion.
As part of the course, women like Paulo and Rashmi learn how to assemble solar power circuits, mobile chargers, fixed solar units and lamps, items which are then shipped to their villages when they return home.
At Tilonia, any woman over the age of 35 who hails from a remote, inaccessible, non-electrified area of the world, can enrol for the international solar training course, provided she is backed by her village. Indian government pays the airfare and six months' training cost for the women.
Ambassadors from Mexico, USA, Togo and Brazil were among those who participated in the event.
