SELCO-India created solar panels to provide electricity to a large part of the population. More than 1.6 billion people worldwide do not have connection to electricity. The Solar Home Lighting System allows families worldwide to have wireless solar power.
This work promotes positive social change because it allows families to be more productive. They do not have to spend money on expensive batteries, candles and kerosene. The light in the evening allows for family members to pursue income-generating activities. It also provides better lighting for studying.
With the Solar Home Lighting System families can focus on other aspects of their lives that they want to improve and be more productive. Previously they only had the hours of daylight to be productive. Now families have more hours in the day to make money and study. This leads to positive social change. Now that the huge burden of providing light and electricity is taken off, that energy and time can be put elsewhere. It promotes studying and working harder which is a positive aspect of social change. This system is currently being used in Sri Lanka, Bhutan and Vietnam successfully.
