The Sun Shines for All-An Electrification Model for Rural Africa?

In Globalenvision:

To appreciate founder Fabio Rosa's Solar Home System, it's essential to pay attention to the details: when you are designing a business to deliver solar energy at low cost to an under-served mass market - as Rosa is doing in rural Brazil - there is no room for human error.
So the batteries must be protected with special boxes and numbered locks. And the plugs all have to be designed to fit one-way - because inadvertent reversal of polarity will damage the system. And finally, in an inspired touch, you may even decide to attach a miniature sculpture of a saint to the battery box to serve as a daily reminder to the customer that the battery -- the energy store -- must be treated as sacred.
