We see the transformational change that you get when people have access to this power. It’s not just a case of saving money, it enables people to do things that they previously couldn’t, because they have access to information, to media and to light.

People can do things that they previously couldn’t, because they have access to information, to media and to light

Azuri is bringing affordable electricity to consumers in emerging countries that lack access to the grid. Indigo is the company's “pay-as-you-go” sustainable solar lighting product currently available in Kenya, Zambia, Malawi and South Sudan.

By combining solar and mobile phone technology, Indigo is paid for with scratchcards through a service model. Users receive 8 hours of fume-free lighting for two rooms and mobile phone charging, whilst cutting their weekly energy spend by 50% or more. Customers can progressively up-grade to larger systems over time, to access more electricity and ultimately reach full home electrification.
