The technical solution is a thin film panel, measuring 165mm x 237mm with a long cable and 2mm Nokia plug interface. Weighing only 93 grams, the solar charger is highly portable.
The solution is incredibly simple and efficient. With one minute of charging, consumers will get approximately two minutes of talk time. The solar charger is most efficient when used in direct sunlight where the average charging time for full charge on a 1000mAh battery would be under four hours. However, the solar panel can also be used behind a glass window, but is less efficient in these conditions.
According to Nokia, Kenya and Nigeria provide the perfect opportunity for testing this solution, with recent World Bank reports indicating that only 16 and 51 percent of Kenyans and Nigerians respectively had regular access to electricity between 2007 and 2011.
However, mobile phone usage is pervasive in these markets, calling for alternative methods of power. ”There are numerous advantages to this solution, including being able to service consumers outside of regular electricity supply, or those who need a quick charge on the go,” says James Rutherfoord, Vice President Nokia West Africa. “However, perhaps the greatest benefit is the cost saving achieved by being able to harness the natural resource of the sun”.
Initial limited quantities of the DC-40 solar charger will be available in Nigeria at retail outlets across Ikorodu, Ibadan, Ojo/Badagry and Ijebu-Ode/Sagamu at an estimated retail price of N2, 560 with the aim of getting
feedback from the field.
