Nearly 400 million Indians, mostly those living in rural communities, lack access to grid power. For many of them, simply charging a cell phone requires a long trip to a town with a recharging kiosk, and their homes are dimly lit by sooty kerosene-fueled lamps.
To change that, Nikhil Jaisinghani and Brian Shaad cofounded Mera Gao Power. Taking advantage of the falling cost of solar panels and LEDs, the company aims to build and operate low-cost solar-powered microgrids that can provide clean light and charge phones. Microgrids distribute electricity in a limited area from a relatively small generation point. While alternative solutions, such as individual solar-powered lanterns, can also provide light and charge phones, the advantage of a microgrid is that the installation cost can be spread across a village. The system can also use more efficient, larger-scale generation and storage systems, lowering operational costs.
