In a situation where most people do not have regular power supply at home, they rely on the gracious "generator" owner or mobile phone charging centre owner who agrees to charge the mobile phone batteries for a fee. This generator owner has built a board with about 20 power sockets and mobile phone chargers. This board is connected to a small petrol powered generator. The fee for the service ranges from 30 - 50 Naira. A mobile phone requires an average of three hours with a desktop charger. The frequency of charges per customer ranges between one per day to twice per day depending on the frequency of calls made by the customer and the state of the battery. But with the fluctuating cost of the petrol to fuel the generator and sometimes fuel scarcity, one wonders whether an alternative e.g the solar powered phone charger would not do well in Nigeria. Nigeria is also endowed with an average daily sunshine of 6.25 hours, ranging between 3.5 – 4.0 peak sun hours at minimum at the coastal areas and 5.0 – 5.5 peak sun hours at minimum at the northern region. The northern region of Nigeria can have a maximum of 9.0 peak sun hours.
But anybody who wants to sell these mobile phone chargers should have the right market in mind. Most of the phone chargers in the market priced above the purchasing power of the average man. The manufacturers seem to the wrong people (the middle class) in mind. These middle class people prefer to charge their phones at home and they have generators for power supply. They also have car chargers just in case the battery dies during the day and they are not near a power source. They are also not so environmentally conscious to bother about environmentally friendly products.
I think the market is for the low income earners such as the drivers, artisans and the manufacturers should have these people in mind. They are the ones that would appreciate these solar powered battery chargers but they must within their expected price range. Manufacturers take note.
But what would happen to the "generator owners or mobile charging centers"? Hmmmm.......
