Off Grid Decentralized Solar Power System for Home Lighting Solutions with Energy Efficient Alternatives and Sustainable Development A Solar-DC Initiative

Abstract

It is an effort in the direction of energy efficient alternative for home lighting system. It proposes the off grid decentralized solar power system. An Existing setup of electricity generation is centralized. It generates electricity centrally at one place (e.g. Thermal power plant) and it is transmitted and distributed everywhere. More over coal is the raw material for such thermal power plants and to save nature we have to put efforts to minimize the use of coal and initiate sustainable ways to generate power which reduces the CO2 emission. One approach is to generate power at a place where we need it. If we are able to generate power in decentralized way, our dependency on grid power can be reduced. As we know that solar panel generates DC Voltage and we can develop 12V DC system or 24V DC system, which does not require conversion from DC to AC. So, use of inverter can be avoided. This is possible as DC bulb, DC LED tube lights, DC fans, BLDC ceiling fans are available. Focus areas of this project: Replicable, Low cost, Easy to install & maintain, Repairable, Easily available components, portable and compact.
