Sumitrabai Kendre sells tea and biscuits on the footpath in Koregaon Park, Pune, India. Her clients are office goers during the day and passers-by at night.
She used to use a small rechargeable electric lantern for the nights. Her daily expense to re-charge her lantern battery was Rs.20. She bought a solar device with KPay and was paying Rs.12.5 per day (for 4 hours of operation). For her this was a huge saving and she has now paid off the cost of the device and it is completely free for her. This saving has allowed her to provide more for her family.
