Households pay a deposit and then daily or weekly micro-payments via mobile money (M-Pesa), with a GSM/M2M chip that locks the unit if payments stop. Once the payments are completed, the customer owns the solar kit. The model turned an unaffordable purchase into a financeable asset for off-grid and underbanked households, and later expanded into financing for smartphones, appliances and loans.● Scaled· scale national
