Solar Lights and Basic Electric for Chintamani
Team Member: Lucas Spangher
EVENT DATE Aug 10, 2016
UPDATE: We have succesfully piloted our first plant, and the lights are on! The inauguration was on 12 May, 2015, and the first ten villagers of Bommekall are now using their new 285W system. So far, no problems!

Consistent electricity is a luxury that we often take for granted. Our goal here in Chintamani, Karnataka, India, is to provide solar lighting to villagers who aren't afforded this luxury. The financial model our team contructed is set in a way that the villagers pay for their system, and the money that they pay goes directly to a fund that provides solar to another village in need, administered by ADATS, the NGO I am currently working for. Our system consists of a 285 Wp solar module with an inverter and battery that links to ten to twelve houses, providing an electricity budget of 25 W per house with four hour backup. In order to be included in the scheme, the villagers agree to a downpayment and monthly fee that is payed forward to the next system the NGO constructs. With your help, we can create a self perpetuating program that brings light to those who are in the dark.

As a colleague and friend of Emmanuel, I second everything he is written, and affirm the positive potential of this project. I am the technical manager of this project, and thus I have contributed much of the electromechanical design. We are doing things that are unique to other microgrids; namely, the use of spatial statistics in optimizing grid layout. For example, we use a graph theoretical approach called "minimum spanning trees" to find the shortest connection between all nodes. This reduced wire use and transmission loss over a naive approach by almost 50%. Second, we mark spatial outliers and temporarily exclude them from grids with the goal of including them in future grids nearer to their home in order to maximize community and, again, minimize wire and transmission losses.
Please check out the pictures we have posted of the spatial statistics employed, and of the pictures recently added showing the pilot.
