Rural areas of Asia and Africa where children lack access to high-quality educational opportunities tend to also be energy poor. Solar lanterns and other small solar energy products, commonly termed “picoPVs”, have been promoted as a promising first step toward improving both lighting in homes and educational outcomes. Rural households throughout Asia and Africa have bought over 100 million picoPVs since 2010, with India, Bangladesh, and other South Asian markets being among the most “vibrant” (and receiving significant market development support from governments and development agencies).
