This case study documents the experience of a private company disseminating rechargeable solar lanterns to off-grid households in rural Lao PDR as an alternative to the use of diesel. By constructing solar charging stations and distributing rechargeable lanterns, Sunlabob uses an innovative method of service delivery: end-users only pay for the charging, rather than for the lanterns themselves. This fee-for-service model effectively enables poor households in off-grid areas to buy hours of solar lighting, offering a cheaper, cleaner and safer alternative to kerosene lamps.
