The Azuri Duo by Azuri Technologies is designed to provide a source of power for lighting and mobile phone charging using solar panels and a battery. Azuri’s service model allows customers to pay a $10 installation fee and then rent to own the system using mobile money or purchasing IndiGo scratchcards. If payments aren’t met, the unit powers off until the next payment is made. After paying off the entire system, users have the option of “unlocking” it for free, unlimited use, or upgrading to a larger model.
The 5 watt Azuri Duo was previously the 2.5 watt Indigo Duo.
Azuri Technologies is located in Cambridge, England with additional operations in Malawi, Ghana, Kenya, South Africa, Zimbabwe, Uganda, Rwanda, Tanzania and Ethiopia.
