This paper presents an innovative approach to tackle the crisis of electrification of off grid and near off grid homes by using the innovative Inverterless Solar DC system. Improved efficiency, lower cost and robust design makes it a very attractive solution. Inverterless system is not only cost effective to power off grid homes but as and when grid becomes available, it can be seamlessly integrated. For homes which are connected to the grid but face load shedding, this system provides uninterrupted power. This paper presents the technical design details of this system. © 2016 IEEE.

Inverterless Solar- DC system design for off- grid and near off-grid Indian homes

2016 1st International Conference on Sustainable Green Buildings and Communities, SGBC 2016

It is well established that access to energy is closely linked with socioeconomic development. India houses the largest share of the world's population deprived of electricity with about 237 million people lacking access (International Energy Agency). At the same time, in India, many households that do have access to electricity lack an uninterrupted and quality power supply. A recent study conducted by the Council for Energy, Environment, and Water (CEEW) across six states (Bihar, Jharkhand, Madhya Pradesh, Uttar Pradesh, West Bengal, and Odisha), found that about 50% of the households had no electricity despite having a grid connection. This indicates that there is an immediate need to address the quality, affordability, and reliability of the power supply in addition to extending the grid footprint. © 2013 IEEE.

Solar-dc Microgrid for Indian Homes: A Transforming Power Scenario

India is a power deficit country and one third of its homes are off grid or near off grid. This paper presents an efficient and affordable Solar DC solution for powering such homes. Though several solutions have emerged in the past for powering these homes, those have been expensive and energy inefficient. These solutions rely on several DC to AC and AC to DC conversions, to feed the widely used AC home loads, thus, wasting a large chunk of the expensive power. The proposed Solar DC solution for off-grid homes (OGH) is developed to use the generated PV power efficiently. With this solution, the panel and battery size is reduced by 2 to 2.5 times and the cost to power a house is reduced to nearly half the cost of the existing solutions. The paper also presents a techno-economic comparison between the proposed OGH solution with some existing solar systems. © 2015 IEEE.
