Farmers Foil Utilities Using Cell Phones to Access Solar

In October, Bangalore-based Simpa Networks Inc. installed a solar panel on Anand’s whitewashed adobe house along with a small metal box in his living room to monitor electricity usage. The 25-year-old rice farmer, who goes by one name, purchases energy credits to unlock the system via his mobile phone on a pay-as-you-go model.

When his balance runs low, Anand pays 50 rupees ($1) — money he would have otherwise spent on kerosene. Then he receives a text message with a code to punch into the box, giving him about another week of electric light.
When he pays off the full cost of the system in about three years, it will be unlocked and he will get free power.

Across India and Africa, startups and mobile phone companies are developing so-called microgrids, in which stand- alone generators power clusters of homes and businesses in places where electric utilities have never operated.

Very cool. Worldwide, approximately 1.6 billion people have no access to electricity and another 1 billion have extremely unreliable access. The poorest spending up to 30% of their income on inefficient and expensive means of providing light and accessing electricity. Solutions like this, finding engineering solutions for basic needs that are market based, are great.

That the poor end up owning their solar system after just 3 years is great.

Creating great benefit to society with the smart adoption of technology and sustainable economics is something I love.
