Investors led by Japan’s Marubeni Corporation have made a $26m investment in UK pay-as-you-go solar company Azuri Technologies. Azuri, which has offices in Nigeria, Kenya, Tanzania, Uganda and Zambia, said the capital infusion would enable it to accelerate expansion in existing sub-Saharan Africa markets and roll out its solar lighting, TV and additional services into new markets. Azuri has sold more than 150,000 solar home systems and has adopted a comparatively cautious approach to building its business.
