Sunny countries are often poor. A shame, then, that solar power is
still quite expensive. Eight19, a British company by Cambridge University, has,
however, invented a novel way to get round this. In return for a deposit
of around£10 it is supplying poor Kenyan families with a solar cell able to
generate 2.5 watts of electricity, a battery that can deliver a three amp (安培) current to store this electricity, and a lamp whose bulb is a
lightemitting diode (二极管). The firm thinks that this system, once the battery is fully
charged, is enough to light two small rooms and to power a mobilephone charger
for seven hours. Then, next day, it can be put outside and charged back up
again.
The trick is that, to be able to use the electricity, the system's
keeper must buy a scratch card — for as little as a dollar — on which is
printed a reference number. The keeper sends this reference, plus the serial
number of the household solar unit, by SMS to Eight19. The company's server
will respond automatically with an access code to the unit.
Users may consider that they are paying an hourly rate for their
electricity. In fact, they are paying off the cost of the unit. After buying
around£80 worth of scratch cards — which Eight19 expects would take the
average family around 18 months — the user will own it. He will then have the
option of continuing to use it for nothing, or of trading it in for a bigger
one, perhaps driven by a 10watt solar cell.
In that case, he would go then through the same process again,
paying off the additional cost of the upgraded kit at a slightly higher rate.
Users would therefore increase their electricity supply steadily and
affordably.
According to Eight19's figures, this looks like a good deal for
customers. The firm believes the average energystarved Kenyan spends around£10 a month
on oil — enough to fuel a couple of smoky lamps — plus£2 on
charging his mobile phone in the marketplace. Regular users of one of Eight19's
basic solar units will spend around half that, before owning it completely.
Meanwhile, as the cost of solar technology falls, it should get even cheaper.
