Solar Mamas: The Story of Sanjit "Bunker" Roy and the Grandmothers Who Became Solar Engineers

The incredible true story of engineer and social activist Sanjit "Bunker" Roy who taught the concepts of solar engineering to grandmothers in a remote village in India.



The radiant sun shines gloriously upon the desert village Tilonia in India, but as night falls, the village plunges into darkness without electricity to keep the lights on. When Sanjit "Bunker" Roy, a young engineer, visits the village, he's inspired to show the men how to use the sun to generate electricity through solar engineering. But with this new knowledge, the men leave their home for greater opportunities in the city. Disappointed, Bunker Roy looks around and wonders who is likely not to abandon their home... and turns to the grandmothers in the village!



The grandmothers are curious and willing to try, but solar engineering is complex. With collaboration, commitment, and hope, the women master the intricacies of circuits and panels to equip the entire village with solar power! Now as night falls, Tilonia and many other villages shine brightly thanks to Bunker Roy and the Solar Mamas.



With poetic text by Jyothi Nookula and dazzling illustrations by Nabi H. Ali, Solar Mamas is the powerful true story of a visionary engineer and a group of dedicated grandmothers who challenged societal expectations to harness the power of the sun. Now their community--and future generations of women--may shine glorious and great.
